Abstract

The effect of different dietary levels of nucleotide supplementation on performance, carcass characteristics, immune system status, small intestine morphology and ileal microbial population of broiler chickens was evaluated using 308 one-day-old mixed-sex Ross 308 broilers in a completely randomized design with four treatments and seven replicates of eleven chicks in each, up to 42 days of age. Experimental treatments included a corn-soybean meal basal diet (control), and the basal diet containing 0. 05, 0. 1 and 0. 2 percent nucleotide supplementation. The results showed that feed intake, body WEIGHT GAIN and feed conversion ratio of the broilers were not significantly affected by experimental treatments. Results of humeral immune system response at 35 days of age showed that the blood serum IgM concentration in 0. 2% nucleotide group was higher than 0. 05% group (p< 0. 05). Also, Serum IgG concentration in this age in 0. 05% nucleotide group was higher than 0. 2% group (p< 0. 05). At 42 days of age, serum IgG concentration in 0. 1% nucleotide treatment was lower than control group (p<0. 05). The cellular immune system response of chicks fed diet supplemented with 0. 1% nucleotide at 48 hours after Phytohemagglutinin-P injection was higher than control treatment (p<0. 05). On the basis of current experiment results, supplementation of broiler diets with nucleotide improves cellular immune system response but has no significant effect on other parameters of broiler chickens.
