Kerala Agricultural University, Thrissur
The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively.
Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively.
On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs.
In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc.
During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU).
Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

ThesisItem Open Access Effect of induced stress and antistress agents on the physiological parameters in broiler chicken(Department of Physiology, College of Veterinary and Animal Sciences, Mannuthy, 2003) Srinivas Reddy, Bellur; KAU; Philomina, P TIn modern poultry production system various factors namely floor space reduction, feed and water restriction, high environmental temperature, vaccination, medication, debeaking etc. have the potential to induce stress in poultry which results in poor performance as well as reduction in immune response as the nutrients normally utilized for growth and production are diverted to counteract the stress and survival. The study was undertaken with the objective of evaluating the influence of induced stress and anti stress agents (dietary ascorbic acid and Zeetress®) on various physiological, biochemical and production parameters in broiler chicken. Fifty six numbers of day old broiler chicks (Vencob) procured from a commercial hatchery were reared in battery cages under the standard managemental conditions upto four weeks of age. Then they were randomly selected and divided into seven groups (G-I to G- VII) with eight birds per group. The birds in different groups were as follows: G-I as the control, G-II as floor space reduced group (33%), G-III as floor space reduced group supplemented with Zeetress® @ 0.01%, G-IV as floor space reduced group supplemented with ascorbic acid @ 0.02%, G- V as 30% feed restriction, G- VI as 30% feed restriction with dietary supplementation of Zeetress® @ 0.0 I % and G- VII as 30% feed restriction with dietary supplementation of ascorbic acid @ 0.02%. The birds were maintained in battery cages under standard managemental conditions on broiler ration with the exception of floor space reduction, feed restriction and incorporation of dietary anti stress agents. Production parameters such as weekly weight gain and feed efficiency were analyzed on weekly basis. Blood was collected with suitable anticoagulants, initially at fourth and then at sixth and eighth week of age. Whole blood was utilized for analysis of haematological parameters, heterophil: lyrnphocyte (H:L) ratio and mitogen induced lymphocyte proliferation test. Plasma was utilized for biochemical analyses i.e. for protein profile, lipid profile and estimation of glucose, uric acid and cortisol. The data were statistically analysed by appropriate tests. The birds of G- V group showed significantly lower values of TEC, Hb, VPRC and TLC at sixth and eight week of age. The dietary supplementation of Zeetress® and ascorbic acid in floor space reduced groups feed restricted groups did not show any significant influence on the values of TEC, Hb, VPRC, ESR, TLC when compared to the birds of respective stress induced groups G-II and G- V. The birds of stress induced groups G-II and G- V had lower lymphocyte count and higher heterophil and basophil count, higher H:L ratio and suppressed mitogen induced lyrnphocyte proliferation (probably due to a rise in level of plasma corticosteroids as a result of stress response) when compared to birds of G-J group, both at sixth and eighth week of age. Dietary supplementation of Zeetress® and ascorbic acid in floor space reduced groups and feed restricted groups elevated the lymphocyte counts, suppressed heterophil and" basophil counts, H:L ratio and considerably improved the mitogen induced lymphoblastogenic response both at sixth and eighth week of age. In the present study the birds of G-II and G- V group had no significant variation in plasma protein profile and glucose levels but had increased plasma concentration of ortisol (probably due to stress induced adrenal hyper activity) and decreased uric acid, when compared to birds of control group G-I, both at sixth and eighth week of age. Dietary Zeetress® and ascorbic acid supplementation in floor space reduced groups and feed restricted groups showed a lower plasma concentration of cortisol both at sixth and eighth week of age, and significantly increased uric acid at eighth week of age. Dietary supplementation of Zeetress® and ascorbic acid in floor space reduced groups decreased plasma concentration of cholesterol both at sixth and eighth week of age and total lipids at sixth week of age. In birds of feed restricted G- V group plasma concentration of cholesterol, triglycerides and total lipids were lower both at sixth and eighth week of age when compared to birds of control group G-I. The dietary supplementation of Zeetress® and ascorbic acid in feed restricted groups had no significant influence on plasma concentration of cholesterol both at sixth and eighth week of age. However, there was an increased concentration of triglycerides both at sixth and eighth week of age with significant increase in total lipids at eighth week of age, when compared to birds of G- V group. There was no significant variation In body weight and weight gain of birds in all floor space reduced groups compared to birds of control group (G-I) at all weeks of age with the exception of lower weight gain in G-IJI and G-IV when compared to G-II at eighth week of age. The body weight and weight gain in the birds of all feed restricted groups were lower when compared to birds of control group (0-1), at all weeks of age. A perusal of the overall feed efficiency from 5 to 8 weeks of age revealed that the birds of 0- VI group supplemented with Zeetress® recorded a superior FE (2.22) whereas an inferior value of 2.59 was noted in 0- V group without any dietary antistress agent. The control group recorded a FE of 2.29. Zeetress® supplementation improved overall FE in feed restricted group (0- VI). On the other hand this advantage was not observed in floor space reduced group (O-IlI). Dietary ascorbic acid improved overall FE only in case of feed restricted group 0- VII when compared to that of 0- V group. However, in floor space reduced group (O-IV), ascorbic acid supplementation could not improve the FE. The observations of the present study revealed that both feed restriction and floor space reduction resulted in some sort of chronic stress which led to variation in haematological and biochemical parameters, and impaired growth (in feed restricted groups). Analysis of TLC, OLC, mitogen induced Iymphocyte blastogenic response and plasma cortisol values indicated that there was a marked level of immunosuppression in the stressed birds. The magnitude of variation in most of these parameters was higher at sixth week of age when compared to that of eighth week values indicating some sort of habituation/ adaptation occurred upon chronic stress in the broiler chicken. The antistress agents - Zeetress® and ascorbic acid were equally effective in reversal of stress induced alterations in haematological, biochemical and production parameters.ThesisItem Open Access Effect of blue green alga (Spirulina platensis) on haematological, biochemical and fertility parameters of egg type male chicken(Department of Physiology, College of Veterinary and Animal Sciences, Mannuthy, 2003) Sethu Nair, C; KAU; Girish Varma, GEnhancement of total production without compromising aspects of wholesomeness and subject Iconsumer lenvironmental safety of the produce forms the new challenge of Indian poultry industry. Since nutrition is the single largest external factor affecting performance of the stock and accounting lion share of the input cost, nutritional manipulations have widely been used to take up this challenge. Especially in the wake of set backs from potential residual hazards of anabolic steroids used as growth promoting feed additives, use of certain blue green algae as dietary supplement offers more innocuous organic alternatives, for being safe to the subject, consumers and environment. Owing to their success in human health with anabolic and therapeutic effects cyanobacteria, the blue green algae, are being tried in livestock/poultry production as well. Spirulina is rich in protein, vitamins and provitamins such as carotenoids, and minerals. Protein from spirulina is believed to be highly digestible due to the lack of a cell wall; it contains 18 amino acids, major ones being lysine, arginine, threonine, methionine and phenylalanine. High levels of arginine is normally believed to be insulinogenic, indirectly through stimulation of growth hormone secretion The present study forms part of an exploration of growth promoting and fertility augmenting aspects of one of the popular species of blue green algae, Spirulina platensis, envisaging evaluation of its influence on haematological, biochemical and fertility parameters of Austra-white male chicken, when used as a dietary supplement. Thirty-two numbers of eight-week-old Austra-white male chickens were reared under standard management conditions in battery cages in Department of Physiology, College Of Veterinary and Animal Sciences. The birds were selected randomly and divided into two groups, G I (control) and G 11 (spirulina supplemented) comprising of sixteen birds in each. Birds of group G I were solely fed with standard layer rution und formed lhe controls in the experiment while birds of G 1I group were fed layer ration with dietary supplementation of Spirulina platensis at the level of 2.5% of feed. Both rations were made isocaloric and isonitrogenous. Feed and water were provided to birds ad libitum. Body weight of the birds was taken at monthly intervals from initial period (eight week of age) to thirty-two weeks of age. Blood was collected at monthly intervals from third to eighth months of age. Estimation of haematological parameters comprised total erythrocyte count (TEC), haemoglobin content (Hb), volume of packed red cells (VPRC), erythrocyte sedimentation rate (ESR) and total leukocyte count (TLC). Erythrocytic indices were calculated from the estimated values of TEC, Hb and VPRC. Biochemical profile of plasma included estimation of total protein, albumin, globulin, albumin globulin (A: G) ratio (protein profile), cholesterol, triglycerides, total lipids (lipid profile), blood urea nitrogen (BUN) and bilirubin at monthly intervals from third to eighth month. Plasma antioxidant status was assessed by estimating catalase enzyme activity and lipid peroxidation level. Semen was collected at twenty- fourth, twenty-eighth and thirty-second weeks of age. Semen evaluation was done by observing the motility, mass activity, semen volume, methylene blue reduction time (MBRT), percentage of live sperms (differential staining and hypo osmolarity swelling) and heat and cold shock resistance tests in the collected semen samples. Birds were sacrificed at thirty-two weeks of age and the relative organ weight of liver,' spleen, pancreas and testes was estimated. Lipid peroxidation level of homogenized samples of liver, spleen, pancreas and testes were also estimated. The data were statistically analysed using appropriate tests. Body weight of birds fed with spirulina (G II group) was significantly higher when compared to control (G I group). Relative organ weight also showed a significantly higher relative weight for spleen, pancreas and testes. The birds of G II group tSpirulina platensis- fed) showed a significantly higher values of TEC, Hb concentration, VPRC and TLC compared to control (G I group) birds. The value of ESR was significantly lower for the spirulina fed group. Plasma protein profile indicated a significant higher concentration of total protein, albumin and globulin levels in spirulina-fed group. Plasma lipid profile had a low total lipid and cholesterol level in spirulina fed birds of G II group when compared to the controls in G I group. However, the triglyceride levels was significantly higher for spirulina fed birds (G II group). Plasma concentrations of BUN and bilirubin were also significantly higher for G 11 group. The results indicated a strong haematopoietic effect of spirulina and its usefulness as a protein rich nutritional supplement for poultry. Plasma antioxidant activity was significantly higher for G II group in the sense that the spirulina fed group showed an increased blood catalase activity and a decreased plasma lipid peroxidation levels. Estimation of peroxidation level in homogenised samples of liver and testes also had a significantly lower peroxidation level in birds of G 11 group. Results underlined the strong antioxidant capacity of spirulina. Semen evaluation studies revealed a significantly higher semen volume, motility, and percentage of live sperms in semen samples from birds of G II group (spirulina fed) when compared to G I group. Semen samples from G II group also showed a significantly lower methylene blue reduction time compared to G I group. Heat and cold shock resistance test failed to show any significant difference between the two groups. Results indicated the fertility augmenting property of spirulina. The present study is consistent with earlier reports of growth promoting and erythropoietic effects of spirulina. Free radical scavenging effect of this species of alga has caused a marked increase in the antioxidant status of the subjects, congruent with earlier findings. Additionally, this is the first publication to report indications of a fertility augmenting effect of this alga in male birds. However, confirmation of the latter effect needs further investigation, preferably with insemination studies.ThesisItem Open Access Metabolic and endocrine profile of crossbred pre-ruminant calves under extended colostrum feeding(Department of Physiology, College of Veterinary and Animal Sciences, Mannuthy, 2003) Babitha, V; KAU; Philomina, P TColostrum is a highly fortified source of nutrients having seven times proteins, twice the total solids, higher content of vitamins, minerals and a very high immune value than normal milk. In most of the commercial dairy farms where day old weaning of calves is practiced, lion share of this potent calf protein supplement is practically wasted since colostrum is unmarketable for human consumption. In this circumstance, the present study was undertaken with the objective of evaluating the effects of enhanced feeding of preserved colostrum in neonatal cross-bred calves on the health status, growth, haematological, biochemical and hormonal parameters and to find any correlations exist among these factors during their first month of life. Fresh colostrum was collected in hygienic conditions from recently calved healthy cows from the first six milkings and then pooled. The pooled colostrum was preserved in dry sterile bottles by deep freezing at -20°C until fed to calves. Crude protein content of colostrum and whole milk were estimated. Total. viable count of pooled colostrum samples were recorded before and after ultra violet irradiation for 30 minutes. Twelve numbers of healthy neonatal crossbred calves of either sex of the Kerala Agricultural University Livestock Farm, College of Veterinary and Animal Sciences, Mannuthy were divided into two groups as Group I (control) and Group II (experimental) with six calves in each group. The calves of group I were fed with colostrum for three days and then milk (one-tenth of body weight) as followed in the farm. The calves of group 11 were fed with colostrum for 30 days of age continuously at the rate of one-tenth of body weight. All calves / were provided with drinking water ad libitum and calf starter (250 g/day/calf) from 15 days of age. The animals were maintained under standard management conditions. Regular monitoring of clinical health status and individual weighing at weekly intervals from day zero (on the day of birth) to one month of all the calves were performed and recorded. Blood samples were collected from the calves of both groups soon after birth (zero day), thereafter 18 h after birth (first day), sixth day, twelfth day, eighteenth day, twenty fourth day and thirtieth day of age. The blood samples were analysed for blood glucose level and haematological parameters like haemoglobin content, total erythrocyte, total leukocyte count, volume of packed red blood cells (VPRC) and subsequently the erythrocyte indices were calculated. Estimation of concentration of serum total protein, albumin, globulin, total lipids, cholesterol, triglycerides, non- esterified fatty acids (NEF A), urea nitrogen (BUN), creatinine and bilirubin were conducted. Hormonal profile of serum thyroxine (T4), triiodothyronine (T3) and insulin were estimated. Clinical parameters of both the groups of calves were within the normal range. Calves of group II recorded a higher weekly body weight gain. Of the various haemotological parameters evaluated, haemoglobin concentration and volume of packed red blood cells exhibited a declining trend, probably due to the haemodilution after intake of colostrum and milk. The total erythrocyte count remained almost constant whereas WBe count showed a persistently an ascending pattern in both the groups, increasing trend in calves of both / protein and globulin also exhibited groups. Serum concentrations of total which can be attributed to the enhanced absorption' of unaltered immunoglobulins by pinocytosis, the property which is lost soon after the maturation of intestinal epithelial cells. Although serum albumin showed a reduction in concentration after first colostrum intake, due to the increased absorption of unaltered immunoglobulins from colostrum, albumin concentration showed a steady rise thereafter till the end of the experiment indicating the enhanced hepatic albumin synthesis. The electrophoretic separation of serum protein components of both groups of calves agreed closely with the biochemical estimation. A steady progressive increase was observed in serum concentrations of total lipids, cholesterol and triglycerides of calves of both the groups throughout the experimental period with the magnitude being more in case of experimental group. This might be explained by the increased . fat content of colostrum, obviously due to an increased requirement of these components as membrane constituents and as energy reserves for the build up of body size and weight. Elevated insulin release stimulated by increased availability of amino acids would have favoured an increase in triglyceride synthesis. Fluctuating pattern in serum EF A status of both the groups might signify reduced mobilisation of fat reserves for energy demands after birth: Blood glucose level of calves of both the groups followed a continuous upstream trend, attributed to the increased energy demand for the enhanced growth. A progressive increment In BUN was more evident In experimental calves. This could be due to the higher protein degradation and subsequent / amino acid deamination, probably as a consequence of the high intake of crude protein and amino acids that were not utilised for protein. synthesis. The decreasing trend of serum creatinine levels in both the groups could be due to the decreased glomerular filtration rate (GFR) of serum creatinine at birth leading to a high serum level at birth, which was reduced later due to the elevated GFR of creatinine during the early days of life. Increased serum bilirubin soon after birth could probably be due to the increased destruction of foetal haemoglobin (Hb) for the replacement of adult haemoglobin after birth. The serum bilirubin levels diminished towards the last quarter of the experiment tenure. Serum thyroid hormones eT3 and T4) were not found to be influenced by time or amount or colostrum or milk fed to calves. There was a fluctuating trend of T3 and T4 ratios in both the groups. The increase in insulin concentration after birth in both the groups of calves could be a consequence of enhanced insulin secretion as a result of greater nutritional intake in the neonatal life. The present investigation proved that increased dietary protein In neonatal cross-bred calves which were fed colostrum continuously for 30 days from birth brought about elevated protein anabolism in association with haematological, biochemical and hormonal changes. They were definitely having an advantage over calves fed colostrum for three days and then switched to milk as per standard feeding regime. Postnatal growth of ruminants is chiefly influenced by metabolic hormones, the secretion of which being regulated by the circulating levels of critical amino acids. The observations of the present / study revealed that nourishing the neonatal calves with protein rich colostrum for a prolonged period ensured increased availability of amino acids, especially the critical ones which can be exploited in enhancing the growth rate of the calves. Since, there is always an interest in maximising the utilisation of protein supplements, the most expensive ingredient in ruminant ration, enhanced feeding of preserved colostrum can be a promising method of improving the weight gain and health status of neonatal calves in farm conditions. Excess of colostrum that is usually wasted in large dairy farms, could be properly preserved and fed to the calves as protein rich nutrient.ThesisItem Open Access Haematological studies of alpine crossbreds from birth to puberty(Department of Physiology, College of Veterinary and Animal Sciences, Mannuthy, 2003) Chitra, Joseph; KAU; Sreekumar, K PGoat (Capra hircus), one of the small ruminant, forms an important economic and ecological niche in small farm systems and agriculture The blood constituents differ among animals due to variety of factors viz., species, genetic, sex, age, growth, environmental and disease conditions. Clinical haematology is an indispensable adjunct to study the functions of the body in both health and disease. Haematological parameters are indicators of normal physiological and health status of an animal. The paucity of information on the haematology of goats is one of the major constraints in the physiological evaluation including the adaptability and health status. Besides very little information is available on the variation of the blood parameters of Alpine crossbred kids from birth to puberty. Physiological factors like age, sex and the type of management affect haematological parameters of an animal. Thyroid hormones viz., thyroxine (T4) and triiodothyronine (T3) are the major regulators of various metabolic functions in the body. Hence the present study was undertaken to evaluate the .relationship of age, sex and body weight on these haematological parameters and serum levels of T, and T3 in healthy Alpine crossbred kids from birth to puberty (six months). The present study was conducted in 48 Alpine crossbred kids (24 males and 24 females) of the University Sheep and Goat Farm, College of Veterinary and Animal Sciences, Mannuthy for a period of six months from day old (on the day of birth) to six months (puberty) period. The animals were maintained under . standard managemental conditions. Body weight of all the animals was recorded on the day of birth and thereafter at fortnightly during the entire period of study. Blood samples were collected from all the animals at monthly interval during the six month period. The blood samples collected with anticoagulant were analysed for haematological parameters like haemoglobin content (Hb), volume of packed red blood cell (vpRC), erythrocyte sedimentation rate (ESR), total erythrocyte (RBC) count, total leucocyte (WBC) count, differential leucocyte count (DLC), osmotic fragility of erythrocytes and specific gravity (whole blood) using standard procedures and erythrocytic indices were calculated. The serum separated from whole blood without anticoagulant was subjected for the estimation of icterus index and hormonal parameters like thyroxine (T 4) and triiodothyroxine (T3) using radioimmuno-assay technique. Clinical health status (respiration rate, pulse rate and body temperature) of all the animals were monitored at fortnightly intervals. On age-wise comparison both male and female kids showed significantly higher values for Hb concentration, VPRC and RBC count at day old which may be due to the transfusion of placental blood from the dam to the infant there by a compensatory reduction in plasma volume, leading to higher RBC count, Hb concentration and VPRC at day old. As the age advanced RBC count, Hb concentration and VPRC were decreased. Even though the value of ESR did not reveal any significant difference between age groups an increasing trend was observed as the age advanced. The velocity of sedimentation of the red blood ceIIs was inversely proportional to the number of red blood cells. The higher RBC count at day old may be the reason for a lower ESR value in day old kids in both sexes. At day old MCV showed lower value in both male and female kids. As the age advanced MCV showed an increasing trend and finally remained stable in both sexes. As the kids grew older it is likely that the requirement for oxygen may be more and with no appreciable change in the number of erythrocytes, the increased demand for oxygen is met by increased size of the erythrocytes. The value of MCR did not show any significant difference between age groups while MCRC value foIlowed a fluctuating trend throughout the six month period. Minimum and maximum osmotic resistance of erythrocytes did not show any significant difference between the sex and age groups except for the females where some differences in maximum osmotic resistance was evident during the second month. The capacity of erythrocytes to resist osmotic dilution is related directly to the corpuscle size or MCV. This is in agreement with the results of present study, that as goats having the smallest RBC, showed signs of minimum osmotic resistance even in 0.63-0.68 per cent Nacl solution. The erythrocytes absorb water from the surrounding hypotonic solution and swell until they reach a maximum size known as critical haemolytic volume after which haemolysis occurred. The smaller the erythrocyte, the earlier the initial volume reached. Eventhough specific gravity and icterus index followed a decreasing trend with age did not reveal any significant difference with age and sex. Age-wise comparison of total WBC count in both male and female kids showed an increasing trend with age except the lower value reported at day old age, though Iymphocyte and eosinophil count were decreased as the age advanced. In contrast neutrophil count showed an increasing trend as the age advanced, with the lowest value at day old. The number of monocyte followed a fluctuating trend without any significant influence of age and sex. As the age advanced the serum concentrations of T 4 and T 3 hormone showed an increasing trend with highest value at birth. The level of T4 in the blood represents the algebraic sum of thyroxine secretion and peripheral utilization. Thyroid hormones stimulate basal metabolic rate via metabolism of carbohydrates, lipids and proteins. The increased metabolic demand for oxygen, associated with the increased body size might have resulted in an increased synthesis and release of thyroid hormones. On sex-wise, comparison male kids had higher bodyweight than female kids throughout the six months period. In the early growing period female kids possessed higher values for RBC count and Hb content but towards puberty male kids had the higher values. In male animals testosterone, which has erythroid stimulating activity led to higher RBC count and Hb content at fifth and sixth month of age. In female kids, oestrogen might have suppressed the erythroid activity therefore lower values were observed for the above parameters in the same age. Erythrocytic indices did not reveal any sex-wise significant difference. Osmotic fragility of erythrocytes, specific gravity (whole blood) and icterus index also did not reveal any significant difference between male and female kids. Lymphocyte count during day old age and first month of age showed significant difference between sex, while total WBC count and number of monocytes and neutrophils did not reveal any significant difference between sex. But the eosinophil count showed significantly higher count for males on the day of birth only. No basophil could be detected in the blood smear of male and female kids. The serum hormonal profile of T4 and T3 of male kids showed significantly higher values than their females throughout the six months period, justified that the onset of rapid growth was closely related with the onset of increased serum concentration of T, and T3. In both male and female kids effect of body weight showed a negative relationship with RBC count, Hb concentration, VPRC values and lymphocyte number. In the present study, at birth body weight of male and female kids were lower. As the age advanced, male and female kids showed a gradual increase in body weight in all age groups. However, the values of RBC count, Hb concentration, VPRC, specific gravity (whole blood) and lymphocyte number showed a higher value on the day of birth and followed a decreasing trend as the age advanced. This decreasing trend of all the above parameters with an increasing trend of body weight resulted in a negative correlation between them. But in both male and female kids effect of body weight showed a positive relationship with the values of ESR, MCV, WBC count, neutrophil number and serum T4 and T3 concentration. The increasing trend of all the above parameters with increasing trend of body weight resulted in a positive correlation.
