Abstract:

In order to study the Effect of Taurine on Nutrient Utilization of Diet, development of immune organs and slaughter performance in broiler chicken, 450 commercial generation Avain broilers were randomly divided into 5 treatment groups , each group with 4 duplications, and each duplication with 30 chickens. Fed the basal diet in groupⅠ, and fed the basal diet supplemented 0.05%, 0.10%, 0.15%, 0.20% Taurine in groupⅡ, group Ⅲ, group Ⅳand group Ⅴ, respectively. The test period was 42 days. The results showed that the broilers in experimental group Ⅲ and group Ⅳ all improved greatly (P<0.05) on the utilization of crude proteins and crude fats contrast to the group Ⅰ. On 3 weeks old, the index of spleen of groupⅠ had significant differences compared with group Ⅲ and group Ⅳ (P<0.05). On 6 weeks old, the index of Bursa of Fabricius of group Ⅲ had significant differences compared with groupⅠ (P<0.05). The index of breast muscle percentage and thickness of subcutaneous fat of group Ⅳ had significant differences compared with groupⅠ (P<0.05). The lean meat percentage of group Ⅳand group Ⅴ had significant differences compared with groupⅠ (P<0.05). Taurine added to the ration of broiler chicken could significantly increase the utilization of nutrient and increase the index of immune organs, improve the immune function of broilers. It could also improve the slaughter performance of broiler chicken, significantly increase the breast muscle percentage and the lean meat percentage, but the thickness of subcutaneous fat was significantly decreased.
