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, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-12) Kharvi, Shraddha; Sharma, R.K.
    The present trial was carried out to discern the effect of peppermint and eucalyptus essential oil supplementation on the performance parameters, nutrient utilization, haemato-biochemical and health status related parameters, carcass traits, meat composition and economics of Japanese quails. A total of a total of 180, six days old Japanese quails individually were weighed and randomly divided into five treatments which consisted of three replicates having 12 birds each. The experimental treatment groups were: T0 control (basal diet), T1 (basal diet + 0.2% of peppermint essential oil), T2 (basal diet + 0.2% of eucalyptus essential oil), T3 (basal diet + 0.1% of peppermint essential oil + 0.1% of eucalyptus essential oil) and T4 (basal diet + 0.05% of peppermint essential oil + 0.05% of eucalyptus essential oil). Growth parameters were studied at weekly intervals as well as during different periods viz. Starter (I-II week), Finisher (III-V week) and Overall period (I-V week). A metabolic trial of 7 days duration was conducted after feeding trial i.e., from day 35th – 42nd to determine the impact of peppermint and eucalyptus essential oils supplementation on nutrient utilization. At the end of feeding trial on 35th day, two Japanese quails from each replicate (six Japanese quails/treatment) were randomly selected and slaughtered to study carcass yield, cut up parts yield, organ weights and processing losses. At the same time representative blood and meat samples (thigh and breast) were also collected for study of haemato- biochemical parameters and meat composition. Results of experiment indicated that inclusion of peppermint and eucalyptus essential oils significantly (P<0.05) reduced feed intake, increased body weight gain, improved feed conversion ratio and performance index, with best performance during all the periods was found in T3 group. The nutrient utilization in terms of dry matter, crude protein, ether extract and organic matter were improved with peppermint and eucalyptus essential oils supplementation in Japanese quails with maximum nutrient utilization was observed in T3 group of Japanese quails. The blood profile revealed that TEC, Hb and PCV were improved in all the essential oil supplemented groups of Japanese quails and MCV showed reduction in essential oils supplemented groups. Serum glucose was reduced in peppermint and eucalyptus essential oils supplemented groups except T4, whereas serum total cholesterol levels and serum triglycerides were significantly reduced in Japanese quails of all supplemented groups, except T4 group. Serum LDL cholesterol levels were reduced in Japanese quails of all supplemented groups. Serum HDL-cholesterol was increased in all peppermint and eucalyptus essential oils supplemented groups with maximum value observed in T4 group of Japanese quails. Serum total protein, albumin and globulin were improved in all peppermint and eucalyptus essential oils supplemented groups of Japanese quails. Serum uric acid, serum creatinine, serum bilirubin levels, SGPT and SGOT were significantly reduced by peppermint and eucalyptus essential oils supplementation in Japanese quails. The essential oil improved dressed yield without and with giblets. Cut up parts in terms of thighs, breast and drumsticks and neck weights were significantly (P<0.05) improved in peppermint and eucalyptus essential oils supplemented groups with maximum thigh, neck and breast weight observed in T3, while highest drumstick weight was noted in T2 group of Japanese quails. Peppermint and eucalyptus essential oils improved weight of liver. Processing losses were not affected due to essential oil supplementation. Crude protein and crude fat content in thigh and breast meat was increased in all essential oil supplemented groups except T4. However, moisture and total ash content of thigh and breast muscles were not affected. Combination of peppermint and eucalyptus essential oils supplementation reduced the feed cost per kg weight gain significantly (P<0.05) with minimum feed cost per kg weight gain was noted in Japanese quails of group supplemented with 0.1% peppermint and 0.1% eucalyptus essential oils in combination. From the results of present investigation, it can be concluded that dietary supplementation of peppermint and eucalyptus essential oils in combination at 0.1% and 0.1% concentrations each may be advised to improve growth performance, nutrient utilization, haemato-biochemical and health status related parameters, carcass traits, meat composition and production economics of Japanese quails. Further research may be carried out using these and other essential oils in laying Japanese quails and other species of poultry.

    In the present investigation, a feeding trial of 12 weeks of duration was conducted on 96 Uttara layers of 20 week age to study the effect of dietary supplementation of Arjun (Terminalia arjuna) bark powder on the production performance, egg quality parameters, egg composition, haemato-biochemical parameters, humoral immune response and economics of egg production. The laying hens were randomly divided in to four treatment groups (T0, T1, T2 and T3) four replicates of 6 birds each. The different groups were supplemented with Arjun bark powder at 0, 1g, 2g, 4g/100gm respectively to standard feed. Egg production, Egg quality parameters and Egg composition were studied in different Phase Ⅰ (26th week of age), Phase Ⅱ(32nd week of age) and overall period. At the end of Phase Ⅰ and Phase Ⅱ blood was collected for haematobiochemical parameter analysis. The results of the present trial indicate that dietary inclusion of Arjun bark powder increase egg production, Egg weight and improve Feed conversion ratio significantly (P≤0.05) in T2 group. The shell thickness increases significantly however no significant difference observed in other egg quality traits. The blood picture revealed that Hb, PCV, TEC and TLC values in Arjun bark supplemented groups are significantly improved. No significant difference was observed in egg composition parameters. Serum glucose, cholesterol, LDL, SGOT and SGPT values in Arjun bark supplemented groups decreases significantly and HDL value increases significantly however no significant difference observed in other biochemical parameters. The average serum immunoglobulin concentration increases significantly in Arjun bark supplemented group. The average feed cost per dozen egg (Rs) decreases significantly in Arjun bark supplemented group. From the results of present study it can be concluded that Arjun bark can be used as herbal feed additive/ phytobiotc in poultry diet for higher production and enhanced immunity by incorporating 2 percent of Arjun (Terminalia arjuna) bark powder in the basal diet of Uttara chicken.

    A study on socio-economic profile of poultry farmers in Bazpur tehsil of Udham Singh Nagar district in Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-06) Eqra, Saman; Shive, Kumar
    The survey study was conducted in Bazpur tehsil of Udham Singh Nagar district in Uttarakhand. A total of 112 poultry farmers were randomly selected for socio-economic profile traits in Bazpur tehsil out of which cost and returns were estimated for 102 broiler farmers on the basis of flock size and education level of the farmers. The socio-economic profile traits included were age, gender, flock size, main occupation, family size, family status, education level, food habit, meat consumption, egg consumption, training, social taboos, farming experience, poultry area, religion and source of information of the poultry farmers. Majority (46.43per cent) of the poultry farmers in the study area were in the age group B i.e. 31 to 45 years. The total number of male poultry farmers was found to be 74 out of 112 (66 per cent). The highest number (46.43 per cent) of the responded farmers in study area had large flock size (>3000 birds). In the present study, 59 respondents (52.68 per cent) out of 112 interviewed had poultry farming as their primary occupation. Most (44.64 per cent) of the poultry farmers in the study area were educated upto junior level.The highest number of poultry farmers (49.11 per cent) had large size families (>8 members) and belonged to joint family (62.5 per cent). The 34.82 per cent of the respondents consumed egg 1 to 10 times and similar percentage i.e., 34.82 per cent who consumed 11 to 20 times. The 38.39 per cent of the poultry farmers consumed meat 1 to 5 times in a month. For majority of the poultry farmers (59.82 per cent), relatives were the source of information for the adoption of poultry farming Lowest value of total cost was found for large sized farmers and graduate and above farmers. Highest net returns were obtained for small sized and up to junior level educated farmers as their total returns were maximum. There was highly significant association between meat consumption and education level of farmers. The present data indicates that majority of the junior level educated farmers had neighbours as their source of information. Graduated and above farmers had friends/relatives as their source of information regarding poultry farming. Problems faced by the poultry farmers were lack of quality chicks, price and availability of feed resources, inefficient marketing system etc. It may be concluded from the present study, that highest net returns were observed for small sized farmers. This may be due to the reason that they sold chicken in the local market or individual customers at higher price. Net returns was also highest for junior level educated farmers as they were mostly small flock sized farmers.

Results of experiment indicated that inclusion of thyme and turmeric essential oils significantly (P<0.05) reduced feed intake, increased body weight gain, improved feed conversion ratio and performance index, with best performance during all the periods was found in T4 group. The nutrient utilization in terms of dry matter, crude protein, ether extract and organic matter were improved with thyme and turmeric essential oils supplementation in Japanese quails with maximum nutrient utilization was observed in T4 group of Japanese quails. The blood picture revealed that TEC, Hb and PCV were improved in T4 group of Japanese quails and MCV and MCH showed significant reduction in essential oils supplemented groups except T1 group. Serum glucose was reduced in thyme and turmeric essential oils supplemented groups with minimum in T4 group. Whereas serum total cholesterol levels were significantly reduced in Japanese quails of all supplemented groups, except T1 with minimum in T4 group. Serum triglycerides were reduced in thyme and turmeric essential oils supplemented groups with minimum in T3 group of Japanese quails. Serum LDL cholesterol levels were reduced in Japanese quails of all supplemented groups. Serum HDL-cholesterol was increased in all thyme and turmeric essential oils supplemented groups with maximum value observed in T4 group of Japanese quails. Serum total protein, albumin and globulin were improved in all thyme and turmeric essential oils supplemented groups of Japanese quails with maximum values observed in T4 group of Japanese quails. Serum uric acid, serum creatinine and total bilirubin levels were significantly (P<0.05) reduced by thyme and turmeric essential oils supplementation in Japanese quails. While SGOT and SGPT levels were minimum in T3 group of Japanese quails. Thyme (0.075%) and turmeric (0.125%) essential oils supplementation significantly (P<0.05) improved dressed yield without and with giblets. Cut up parts in terms of thighs, breast and drumsticks weights were significantly (P<0.05) improved in thyme and turmeric essential oils supplemented groups with maximum thigh and breast weight observed in T3 and T4 group, while highest drumstick weight was noted in T4 group of Japanese quails. Thyme and turmeric essential oils improved weights of heart, liver, gizzard and giblets. Processing losses were not significantly affected by thyme and turmeric essential oils supplementation in any treatment group. Best results regarding crude protein and crude fat content in thigh and breast meat was observed in T2 and T4 group. However, moisture and total ash content of thigh and breast muscles were not affected. Combination of thyme and turmeric essential oils supplementation reduced the feed cost per kg weight gain significantly (P<0.05) with minimum feed cost per kg weight gain was noted in Japanese quails of group supplemented with 0.075% thyme and 0.125% turmeric essential oils in combination. From the results of present investigation, it can be concluded that dietary thyme and turmeric essential oils supplementation in combination at 0.075% and 0.125% concentrations, respectively each may be advised to improve growth performance, nutrient utilization, haemato-biochemical parameters, carcass traits, meat composition along with economical Japanese quail production. Further research may be carried out using these and other essential oils in laying Japanese quails and other species of poultry.

    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.

    (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.

    Effect of feeding dried neem (Azadirachta indica) and kadipatta (Murraya koenigii) leaf powder on growth performance, nutrient utilization, carcass traits and haemato-biochemical parameters in broiler chicken
    (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.
