泌乳早期奶牛日粮中添加脂肪酸钙对脂肪代谢影响的研究
Studies on the Effects of Supplementing Energy Additives(Fatty Acid Calcium Salts)on Fat Metabolic of Chinese Hostein Cows in Early Lactation
【摘要】 选择 6头经产、胎次相同、产后 10~ 20天的中国荷斯坦奶牛,采用 3× 3重复拉丁方设计,研究脂肪酸钙对中国荷斯坦奶牛泌乳早期脂肪代谢的影响。试验处理分别为:处理 A组为基础日粮;处理 B组为基础日粮+ 200g脂肪酸钙;处理 C组为基础日粮+ 400g脂肪酸钙。试验结果表明:添加脂肪酸钙使游离脂肪酸水平下降, B组游离脂肪酸水平比对照组下降了 37 83% (P0 05);日粮中添加脂肪酸钙使乙酰乙酸和β-羟丁酸水平下降。
【Abstract】 Six pluriparous Chinese Holstein cows were wsed in a replicated 3× 3 Latiin square design to determine the effects of fatty acid calcium salts on taf metabolic during early lactation.Treatment were basal dies(A);basal diet plus 200g fatty acid calcium salts (B);basal diet plus 400g fatty acid calcium salts(C).The results showed as follows:the FFA concentration were decreased 37.83% in treatment B,decreased 23.35% in treatment C;the concentrations of acetoacetic acid,β- hy droxybutyate,and growth hormone were decreased by supplementation of Ca salts.
【Key words】 fatty acid calcium salts; Chinese Holstein cow; fat metabolic.;
