Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-06) Verma, Rajat; Singh, Brijesh
    In the present experiment, there were two groups constituted of Pearl and Lavender varieties of guinea fowl. A total of 300 day-old keets 150 from Pearl and 150 from Lavender variety of guinea fowl were used. The aim of the experiment was to study comparative egg weight, fertility, hatchability, growth performance, carcass traits, hematological and biochemical parameters in Pearl and Lavender varieties of guinea fowl. For the study of growth performance, body weight and feed uptake were recorded at 2 weekly intervals throughout the experimental period. Growth parameters were studied in three different periods viz. Starter (1st-4th week), Grower (5th-8th week), Finisher (9th-12th week) and overall period (1st-12th) at two weekly intervals. At the end of 84th day, six birds from each group were randomly sacrificed for study of carcass yield, yield of cut up parts, organ weights and processing losses. At that time blood was also collected for haemato-biochemical parameters. The results of experiment indicated that the average egg weights were significantly (P<0.05) higher in Pearl as compared to Lavender variety of guinea fowl. The fertility and hatchability were higher in Pearl than Lavender variety of guinea fowl. Pearl had significantly (P<0.05) higher body weight gains than Lavender during all the periods. Pearl had significantly (P<0.05) lesser feed intake than Lavender variety of guinea fowl. Pearl had significantly (P<0.05) better Feed conversion ratio than Lavender during all the periods. The mean of dressing percentage with and without giblet were significantly (P<0.05) higher in Pearl than Lavender variety. The cut up parts in terms of thigh, breast and drumstick weight were significantly (P<0.05) higher in Pearl than the Lavender group. The organ weights in terms of gizzard weights were significantly (P<0.05) higher in Pearl than the Lavender group. The blood picture revealed that the mean value of Hb was significantly (P<0.05) higher in Pearl than the Lavender variety. The mean values of total protein and globulin were significantly (P<0.05) higher in the Pearl than the Lavender variety whereas albumin was significantly (P<0.05) higher in the Lavender than the Pearl variety. From the results of present investigation it can be concluded that Pearl has better performance than Lavender variety of guinea fowl.

    Effect of various feed supplements on the performance of broiler chickens
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-01) Chauhan, Shailendra Singh; Sharma, R.K.
    A feeding trial was conducted to study the effects of various feed supplementson the body weight gain, feed intake, FCR, nutrient utilization, carcass traits, meat characteristics, sensory characteristics, intestinal morphology, haematological parameters, differential leucocyte count, serum biochemical parameters, serum mineral profile, kidney function test, serum protein profile,serum immunomodulatory parameters, faecal pathogens, NPK contents in poultry litterand economics of broilers. For this purpose, a total number of 396 day old broiler chicks (Cobb) were randomly allocated into eleven groups with three replicates of 12 chicks each. The first treatment group (T0) served as control while in other treatments different supplements were added. The results of the trial indicated that dietary inclusion of organic mineral mixtures, probiotics, enzymes, emulsifier and liver stimulants in broilers showed significantly higher amount of body weight gains and reduction in FCR & feed intake. The broilers of feed supplementedgroups retained maximum amount of dry matter, crude protein, ether extract, calcium and phosphorus as compared to the control group.The dressed & cut up yields and organ weights were significantly increased in feed supplemented groups. The processing losses were significantly decreased whereas crude protein content in breast and thigh meat was significantly higher in supplemented groups. Supplementation in broilers had favourable impact on appearance, flavour, juiciness, texture and overall acceptability of meat. There was a significant increase in the length of duodenum, jejunum, ileum, small intestine, villus height and villus height: crypt depth ratio in broilers of supplemented groups. Significant increase in RBC, Hb, PCV, TLC and DLC was observed in supplemented groups.There was a significant decrease in serum glucose, total cholesterol, LDL- cholesterol and triglyceride levels while significant increase in HDL- cholesterol was seen. There was a significant increase in serum Ca and P while non significant effect on sodium and potassium in feed supplemented groups was observed. There was a significant decrease in urea, uric acid and creatinine in feed supplemented groups. There was a significant increase in total protein, albumin and globulin in feed supplemented groups. There was a significant increase in serum IgG while significant decrease in cortisol level in feed supplemented groups. Faecal pathogens (E. coli and Salmonella enteridis) were absent in all the groups. There was a significant increase in nitrogen, phosphorus and potassium content in poultry litter in feed supplemented groups. There was a decrease in the feed cost and increase in the net profit over feed cost in feed supplemented groups. Thus, it may be concluded that dietary supplementation of basal diet with probiotics + enzymes (Brozyme - XPR) + emulsifier (Lipigon) + liver stimulant I (Superliv premix) @ 0.5 g/kg feed is beneficial and cost effective for poultry farmers. There is no advantage of resorting to 3% energy deprivation in birds as liver stimulants were unabe to compensate it economically.

    Expression and evaluation of immune-potential of recombinant penton base and fibre proteins of Inclusion body Hepatitis-Hydropericardium Syndrome (IBH-HPS) virus of domestic fowl
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Trivedi, Raj Narayan; Rajesh Kumar
    Present study deals with epidemiology and phylogenetic analysis, expression and immune potential of recombinant penton base and fibre proteins of IBH-HPS virus isolates recovered from natural outbreaks. Epidemiological analysis revealed that mortality ranged from 0.5% to 20% and disease outbreak was mainly observed in 21 to 42 days old broiler chickens. Twenty samples, found positive for IBH-HPS virus antigens serologically by AGID, were subjected to virus isolation in CEL culture. Followed by DNA was extracted from infected CEL cells (4th passage). Amplification of L1 loop region (~900bp) of hexon gene was done followed by RFLP analysis with six restriction enzymes which revealed two RFLP pattern. L1 loop region of hexon gene amplicon was cloned and sequenced to determine serotype of IBH-HPS isolates, which indicated that nineteen isolates are FAdV- 11/2 while one is FAdV-8b. L1 loop sequence based phylogenetic analysis revealed that our sequences clustered into one major cluster having similarity with the Fowl adenovirus class D, E and C along with strains FAdV-2, 4, 10, 11, 8b. Penton base and fibre genes from selected isolate (Pantnagar/HA-14/R-21) were PCR amplified and amplicons of about 1713bp and 1668bp respectively were obtained. Cloning and sequencing of the penton base and fibre gene was done and checked for the presence of complete ORF. Both the genes were expressed in E.coli and expressed proteins were found to be immunoreactive in western blotting with known serum. Immune – potential of recombinant proteins was evaluated by inoculating with FCA in SPF chicks. Maximum protection (80%) was observed with fibre protein and antibody titre was maximum for fibre protein at every point of time. Virus shedding was observed in feces for shortest period i.e. upto 8th day post challenge in chicks receiving fibre protein.

    A study on socio-economic profile of broiler farmers in foothills of Kumaon region of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-06) Neha Parveen; Shive Kumar
    The present study was carried out on 120 randomly selected broiler farms in foothills of Kumaon region, Uttarakhand. Socio-economic profile of the farmers was evaluated by dividing their socio-economic characteristics into different categories and cost and returns were estimated only in 45 farms, considering flock size and education as factor. Both flock size and education status were classified into three categories. Farmers were interviewed personally by using well-prepared questionnaire to analyze the effect of socio-economic factors on communication source and to identify various problems faced in broiler farming and suggestions given by the farmers to overcome those problems. Majority of the farmers were young, male, non-vegetarian, untrained, marginal and Hindu, preferred chicken meat and had no taboos in adopting broiler farming. More than half of the broiler farmers practiced broiler farming as a subsidiary occupation and had large flock size. According to flock size average total fixed cost per broiler was Rs. 4.01, total variable cost Rs. 147.13, total cost Rs. 151.15, gross returns Rs.181.83, net returns Rs. 30.69 and BCR was 1.20. According to education average total fixed cost per broiler was Rs. 4.33, total variable cost Rs. 146.81, total cost Rs. 151.13, gross returns Rs.181.79, net returns Rs. 30.66 and BCR was 1.20. The major items of total variable costs were feed followed by day old chicks. It revealed that flock size and education had significant effect on all the components of cost and returns except in case of interest on variable cost, flock size had no significant effect. Based on benefit-cost ratio, investment on broiler farms found most profitable on the large sized farms and on the farms of highly educated farmers. Flock size, land holding and experience had no significant effect on communication source for adopting broiler farming except education, which means education played major role in getting communication from different sources. High feed cost followed by high cost of day old chicks and more fluctuation in price followed by less organized marketing system were major problems at production and marketing level, respectively. Most of the farmers suggested that feed and day old chicks should be provided at subsidized rates and well-organized marketing system should be available in broiler farming.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Naula, Namita; Singh, C.B.
    In the present investigation, experimental, trial was conducted on 120, day old broiler chicks (cob-400 strain) for a period of 6 weeks, to study the effect of black cumin supplementation on the growth performance, carcass traits and certain hemato-biochemical and health status related parameters. In the investigation, experimental broiler chicks were randomly divided into four dietary groups (T1, T2, T3 and T4) each group having three replications consisting of ten broiler chicks each. The different groups were supplemented with black cumin @ 0, 0.05, 0.75 and 1.00 per cent in the experiment. Growth parameters were studied at weekly intervals as well as for starter (I-III week), finisher (IV -VI week) and overall periods (I-VI weeks). At the end of experiment on 42nd day, two broiler chickens from each replicate (six broiler birds/ treatment) were randomly slaughtered for carcass yield, yield of cut up parts, organ weights and processing losses. Representative blood samples were also collected for study of hemato-biochemical parameters. The results of the experiment indicated that dietary inclusion of black cumin in broiler chickens increased body weight gain, increased feed intake, improved feed conversion ratio and performance index significantly (P<0.05), with best performance during all the periods was noted in group supplemented with 0.5 per cent of black cumin. The dressed yield with and without giblet were significantly (P<0.05) affected by black cumin supplementation. Breast and back weight were significantly higher due to supplementation of black cumin. Weight of thigh, drumstick, neck and wings were not significantly affected by black cumin supplementation. Black cumin supplementation significantly improved gizzard weight. Heart and liver weight and processing losses were not affected by black cumin supplementation. Hematological parameters such as TEC, TLC, PCV and Hb values showed significant impact of black cumin supplementation while MCV showed significant decrease and MCH showed non-significant impact of black cumin seeds supplementation in broilers chickens. Decreased concentration of serum glucose, serum cholesterol and serum triglycerides whereas increased concentration of HDL cholesterol was noticed in black cumin supplemented groups. Protein profile showed significant improvement in total protein and globulin with black cumin supplementation and non significant effect on the albumin and albumin-globulin ratio. From the results of present study it can be concluded that, dietary black cumin supplementation at 0.05 per cent level may be advised to improve growth performance and FCR while 1percent level may be advised to improve carcass yield and hemato-biochemical parameters and also decrease in serum total cholesterol and production lean meat of broiler chickens.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-06) Prakash, S.; Palod, Jyoti
    In the present investigation, two experimental trials were conducted on 120, three day old Japanese quails (red plumaged) for a period of 6 weeks each, to study the effect of nucleotide supplementation as yeast extract on the growth performance, nutrient retention, carcass traits, meat composition, haematological, certain serum biochemical and health status related parameters, intestinal morphology and immunological status. In both of the experiments, experimental Japanese quails were randomly divided into four treatment groups (T1, T2, T3 and T4), each group having three replications consisting of ten Japanese quails each. The different groups were supplemented with nucleotides @ 0, 0.5, 1.0 and 1.5 per cent and 0, 0.25, 0.5 and 0.75 per cent in experiment I and experiment II, respectively. Growth parameters were studied at weekly intervals as well as for starter (I-II week), finisher (III -VI week) and overall periods (I-VI). Delayed type of hypersensitivity test was conducted on the 21st day of experiment I, by randomly selecting six Japanese quails from each group for the sensitization test. A metabolic trial of 7 days duration was conducted from 36th – 42nd days of both the experiments to determine the effect of nucleotide supplementation on nutrient utilization. At the end of experiment I on 42nd day, two Japanese quails from each replicate (six Japanese quails/treatment) were randomly slaughtered for carcass yield, processing losses, yield of cut up parts, organ weights and carcass composition. Representative blood samples were also collected for study of haemato-biochemical parameters and humoral immune response. After evisceration the intestine of the birds were carefully separated and the length of the intestine from duodenum to end of the rectum was measured using a measuring tape to study the effect of supplement on the intestinal gross morphology. A sample of two cm from proximal jejunum was collected and preserved in 10 per cent formalin to study the histological changes on the villous height, crypt depth and villous height-crypt depth ratio of the intestine. The results of the both experiments indicated that dietary inclusion of nucleotides in Japanese quails increased body weight gain, reduced feed intake, improved feed conversion ratio and performance index significantly (P<0.01), with best performance during all the periods was noted in group supplemented with 0.5 per cent of nucleotides. The nutrient utilization in terms of dry matter, crude protein and total carbohydrates were significantly (P<0.05) improved in Japanese quails of nucleotide supplemented groups in both the experiments. Utilization of crude fat content was significantly (P<0.05) improved in experiment I with all levels of nucleotide supplementation while utilization was not affected in experiment II. The dressed yield with and without giblet were not affected by nucleotide supplementation. Thigh, breast, drumstick and neck muscles weight were not affected by supplementation of nucleotides. Weight of back muscles were significantly (P<0.05) decreased in supplemented groups. However, wing muscles weight were significantly (P<0.05) improved in Japanese quails supplemented with 1.0 per cent level of nucleotide. Nucleotide supplementation significantly improved the liver and gizzard weight. Heart weight and processing losses were not affected by nucleotide supplementation. Fat content of the thigh and breast muscles were significantly (P<0.05) reduced by nucleotide supplementation. However, moisture, crude protein and total ash content of thigh and breast muscles were not affected. Haematological parameters such as TEC, TLC, PCV, Hb and MCHC values showed significant impact of nucleotide supplementation. Decreased concentration of serum glucose, serum cholesterol and LDL cholesterol and increased concentration of triglycerides and HDL cholesterol were noticed in nucleotide supplemented groups especially at higher levels. Protein profile showed significant improvement in total protein, albumin and globulin with higher levels of nucleotide. Serum creatinine and SGPT contents showed nonsignificant impact whereas, serum uric acid and SGOT contents were significantly reduced in nucleotide supplemented quails. Nucleotide supplementation significantly (P<0.01) improved both humoral and cell mediated immune response. Relative intestinal length, duodenal villous height and V/C ratio were significantly increased while duodenal crypt depth was decreased with all levels of nucleotide supplementation with best results at 0.5 per cent level of nucleotide supplementation. From the results of present study it can be concluded that, dietary nucleotide supplementation at 0.5 per cent level may be advised to improve growth performance, nutrient retention, lean meat production, intestinal morphology and immune status of Japanese quails.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2015-07) Ansari, Vasim Akram; Anil Kumar
    A study was conducted to evaluate the production performance of 275 chicks of two ecotype viz., comb and crown which were obtained in six hatches at Instructional Poultry Farm of G.B.P.U.A. & T., Pantnagar. Body weight was recorded at four week interval from day old to 24th weeks of age. Among comb and crown ecotypes of Uttara fowl, comb male ecotypes showed maximum body weight gain (1780.18±34.69 g), followed by crown male (1699.43±33.49 g), while it was (1484.22±19.22 g) in crown female and minimum in comb female ecotypes (1389.12±18.85 g) among two ecotypes of Uttara fowl. The crown ecotype under study obtained early age at first egg (161.5±3.05 days), with body weight (1422.50±31.21g), whereas comb ecotypes attained age at first egg at later (171.05±2.18 days) with body weight (1350.40±35.35 g). The average egg production up to 72nd week of age in crown ecotypes of Uttara fowl (177.35±6.34 eggs) was found higher than the comb ecotypes of Uttara fowl (153.54±5.64 eggs). The average egg weight were recorded at first egg, 24th, 28th, 32nd, 36th, 40th, and 44th week of age in comb ecotypes were 34.85±0.47, 39.25±0.79, 42.80±0.40, 46.80±0.73, 50.50±0.59, 52.80±0.51 and 53.40±0.21 g, respectively. While corresponding values in crown ecotypes of Uttara fowl were reported as 37.05±0.93, 41.30±1.08, 44.80±0.79, 47.80±0.63, 51.40±0.68, 53.20±0.92 and 54.40±0.84 g, respectively. The mean values of egg weight (g), shell weight (g), shape index, haugh unit, albumen index, yolk index, yolk weight (g), shell thickness (mm), at 32nd weeks of age in comb and crown ecotypes of Uttarafowl were 46.80±0.73, 5.88±0.067, 73.64±0.19, 74.48±0.42, 0.080±0.002, 0.42±0.008, 13.20±0.32 and 0.38±0.028, respectively and 47.80±0.63, 6.16±0.10, 74.31±0.41, 75.20±0.55, 0.082±0.003, 0.44±0.01, 14.80±0.32 and 0.43±0.032, respectively. Thus on the basis of findings reported under study, it may be concluded that Uttara fowl has great scope in rural backyard poultry in Uttarakhand. Uttara fowl has potential to develop as dual purpose bird which can be achieved through intensive selection and breeding program.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2015-07) Khulbey, Ravi; Ashoka Kumar
    A feeding trial was conducted to discern the effect of dietary incorporation of neem and kadipatta leaf powder on growth performance, nutrient utilization, carcass traits and haemato- biochemical parameters in commercial broilers. A total of 120, day-old broiler chicks were divided randomly into 6 treatment groups with 2 replicates each i.e. 10 broiler chicks per replicate. Chicks of treatment T1 (control) were fed basal diet whereas in treatment group T2, T3, T4, T5 and T6, basal diet was supplemented with leaf powder as 0.2% neem, 0.2% kadipatta, 0.1% kadipatta plus 0.3% neem, 0.3% kadipatta plus 0.1% neem and 0.2% kadipatta plus 0.2% neem, respectively. The feeding trial lasted for 42 days viz., 0-21 days (starter phase) and 22-42 days (finisher phase). Feed intake and body weight changes in broiler chicks were recorded at weakly intervals and a metabolism trial of 4 days collection period was conducted during the 6th week of feeding trial. Meat quality analysis viz, cut up parts, dressing percentage, organ weight, processing losses and chemical composition was determined at 6th week of feeding trials. Blood haemato-biochemical analysis as well as shear force values were performed at the end of experiment. During the starter phase, the body weight gain of broiler chicks of treatment group T6 (708.64 g) was significantly (P<0.05) higher than other treatment groups T1 (690.27 g), T2 (694.99 g) T3 (684.28 g), T4 (665.29 g) and T5 (670.15). During 22- 42 days (finisher phase), the body weight gain of broiler chicks of treatment group T6 (1500.46 g) was significantly (P<0.05) higher than other treatment groups T1 (1286.63 g), T2 (1439.11 g) T3 (1335.53 g), T4 (1316.81 g) and T5 (1418.05 g). FCR and Performance index were improved in broiler chicks of treatment groups T6. During whole experimental period (0-42 days), supplementation of 0.2% kadipatta plus 0.2% neem leaf powder improved broiler performance in terms of feed intake, body weight gain, FCR and performance index. Final body weight was recorded highest in T6 (2209.10 g) followed by T2 (2134.10 g), T5 (2088.20 g), T3 (2019.61), T4 (1982.10) and lowest in T1 (1976.90 g). Nutrient utilization in terms of dry matter, crude protein, crude fat and crude fiber was significantly (P<0.05) improved in broilers fed diet supplemented with 0.2% kadipatta plus 0.2% neem leaf powder (T6). Composition of breast and thigh muscles showed significant (P<0.05) difference in supplemented group as compared to control. Significant (P<0.05) difference were observed in Hb, PCV and TEC in broilers of supplemented groups. Significant (P<0.05) reduction in serum cholesterol and glucose were recorded in broilers of treatment groups, whereas, there was no significant difference in albumin, globulin. Significant (P<0.05) increase in serum total protein were recorded in broilers of treatment groups. Serum enzymes activity viz.,SGPT and SGOT showed significant difference (P<0.05) among the broilers of different treatments as compared to control. It is concluded that 0.2 % kadipatta plus 0.2% neem leaf powder in the diet of broilers improved growth performance, nutrient utilization, increase Hb, PCV, TEC or total serum protein and reduced serum cholesterol, serum glucose or serum enzymes which in turn is beneficial and can be recommended for improving performance of broiler chicken.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2015-06) Fonia, Navneet; Singh, C.B.
    In the present investigation, experimental trial was conducted on 120, day old broiler chicks (cobb strain) for a period of 6 weeks, to study the effect of nucleotides supplementation on the growth performance, carcass traits, meat composition, hematological, certain serum biochemical and health status related parameters. In the investigation, experimental broiler chicks were randomly divided into four treatment groups (T1, T2, T3 and T4), each group having three replications consisting of ten broiler chicks each. The different groups were supplemented with nucleotides @ 0, 0.01, 0.03 and 0.05 per cent in the experiment. Growth parameters were studied at weekly intervals as well as for starter (I-III week), finisher (IV -VI week) and overall periods (I-VI week). At the end of experiment on 42nd day, two broiler chickens from each replicate (six broiler chickens/treatment) were randomly slaughtered for carcass yield, yield of cut up parts, organ weights, processing losses, and carcass composition. Representative blood samples were also collected for study of hemato-biochemical parameters. The results of the experiment indicated that dietary inclusion of nucleotides in broiler chickens increased body weight gain, reduced feed intake, improved feed conversion ratio and performance index significantly (P<0.05), with best performance during all the periods was noted in group supplemented with 0.03 per cent of nucleotides. The dressed yield with and without giblet were not affected by nucleotide supplementation. Thigh, breast, drumstick, neck and wing muscles weight were significantly higher due to supplementation of nucleotides. Weight of back muscles were significantly (P<0.05) increased in 0.03 per cent nucleotide supplemented group. Nucleotides supplementation significantly improved the liver and gizzard weight. Heart weight and processing losses were not affected by nucleotides supplementation. Fat content of the thigh and breast muscles were significantly (P<0.05) reduced by nucleotides supplementation. However, moisture, crude protein and total ash content of thigh and breast muscles were not affected. Hematological parameters such as TEC, TLC, PCV, Hb, MCH and MCHC values showed significant impact of nucleotides supplementation. Decreased concentration of serum glucose, serum cholesterol and serum triglycerides whereas increased concentration of HDL cholesterol were noticed in nucleotides supplemented groups. Protein profile showed significant improvement in total protein, albumin and globulin with nucleotides supplementation. SGOT and SGPT contents showed non-significant impact of nucleotides supplementation in broiler chickens. From the results of present study it can be concluded that, dietary nucleotides supplementation at 0.03 per cent level may be advised to improve growth performance, serum protein profile, weight of different cut up parts, liver and gizzard weights, decrease in serum total cholesterol and lean meat production of broiler chickens.
