不同能氮水平日粮对生长期海南黑山羊血液生化指标的影响

试验选用12只生长期海南黑山羊断奶羔羊（约4月龄）分成4组,采用4×4拉丁方设计,以适宜于发展中国家的山羊饲养标准为参考设计了4种能氮比的日粮,分别为日粮1、2、3、4。探讨不同日粮能氮水平对海南黑山羊血液生化指标的影响。结果表明,饲喂日粮2山羊血液中的总蛋白较日粮1、日粮3和日粮4的实验羊显著降低;白蛋白显著降低;尿素含量最高,日粮2与日粮1、日粮3差异不显著,显著高于日粮4;葡萄糖含量,日粮2与日粮3无显著差异,与日粮1、日粮4差异显著;甘油三酯与总胆固醇均成上升趋势,日粮2最低,日粮4最高;谷丙转氨酶、谷草转氨酶和球蛋白含量均无显著差异。

Effects of Different Four Diets on Blood Biochemical Indexs for Hainan Black Goats

Twelve fattening Hainan Black goats at the age of 4 month were used to Study. A 4×4 Latin square experiment design was conducted to study the Effects of Different Four Diets on Blood Biochemical Indexs for Hainan Black Goats of stall-feeding Hainan Black goats fed the four different diets based on recommendation of nutrients requirements of Keral （1982）. The results were as follows： The concentration of rip and ALB in diet 2 was significant difference （P〈0.05） between diet 1 and diet 3,4; The concentration of UREA in diet 2 was highest, and significant difference （P〈0.05） between diet 2 and diet4; The concentration of GLU in diet 2 was significant difference （P〈0.05） between diet 1 and diet 4, there was no significant difference （P〈0.05） between diet 2 and diet3; The concentration of TG and TC tended to increase, The concentration of AST, ALT and GLB were no significant difference （P〈0.05）.
