    Effect of nucleotides supplementation on production, hematological and serum biochemical parameters in 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.
