Comparative Study on Weight Increment Effect and Blood Index of Beef Cattle under Different Genetic Bases
摘要
Abstract
[ Objective ] The aim was to study the influence of genetic bases, nutrition level and the interaction on weight increment effect and blood index of hybrid beef carle. [ Method] Based on 4 ×2 double-factor design,forty-four heads of filial generation were obtained from the hybridization between 4 heads of beef cattle (Churolais, Gelbvieh, Angus and Limousin ) with different genetic bases and female simmental crossbreed cattle, then,2 levels of daily nutrition ration were fed, moreover, the test period was 140 d. [ Result ] Under lower nutrition level, average daily gain of Angus-simmental crossbred beef was higher than that of Churolais-simmental crossbred beef ( P ＜ 0. 05). Under higher nutrition level,albumin content in Limousin-simmental crossbred beef was higher than that in Charolais-simmental crossbred beef and Gelbvieh-simmental crossbred beef (P ＜0.01 ). Under lower nutrition level,albumin content in Limousin-simmental crossbred beef was higher than that in Gelbviehsimmental crossbred beef (P ＜ 0.05 ). Under higher nutrition level ,Total protein content in Limousin-simmental crossbred beef were higher than that in Charolais-simmental crossbred beef ( P ＜0.05 ); TG in Angns-simmental crossbred beef was higher than that in Gelbvieh-simmental crossbred beef ( P ＜ 0.05 ); LDH in Charolais-simmental crossbred beef was higher than that in Gelbvieh-simmental crossbred beef ( P ＜ 0.05 ). Under lower nutrition level, urea nitrogen content in Limousin-simmental crossbred beef was higher than that in Charolais-simmental crossbred beef and Angus-simmental crossbred beef (P ＜ 0.05 ); BUN in Angns-simmental crossbred beef under higher level of nutrition was higher than that of lower nutrition ( P ＜ 0.01 ). Under lower nutrition level,AKP in Limousin-simmental crossbred beef was higher than that in Angus-simmental crossbred beef ( P ＜0. 01 ) and that of Churolais-simmental crossbred beef and Gelbvieh-simmental crossbred beef ( P ＜0.05 ). AKP in Limousin-simmental crossbred beef under lower level of nutrition was higher than that of higher nutrition ( P ＜ 0.05 ). [ Conclusion ] Daily gain,AKP and LDH were influenced by genetic factor significantly,ALB and BUN were influenced by genetic and nutritional factores.关键词
