| 摘 要： | 本试验旨在研究烟酰胺对高产奶牛泌乳中期产奶性能、血液生化指标和经济效益的影响。选取40头泌乳中期的中国荷斯坦奶牛,随机分为4组,每组每头在基础日粮中分别添加0、6、10、14 g/d烟酰胺,检测采食量、产奶量、乳成分、血液生化指标。结果表明:各组奶牛干物质和粗蛋白质采食量差异不显著(P>0.05);烟酰胺的添加对乳脂率、乳蛋白率、乳糖率、乳脂产量、乳蛋白产量无显著影响(P>0.05);添加NAM后,显著降低了血清NEFA含量(P<0.05);而对血清葡萄糖、丙氨酸转氨酶、天门冬氨酸转氨酶、甘油三酯、碱性磷酸酶、尿素氮和胆固醇的影响差异不显著(P>0.05);添加10、14 g/d烟酰胺可比对照组显著增加产奶量0.86和1.34 kg/d(P<0.05)。在泌乳中期奶牛日粮中添加10~14 g烟酰胺,有助于奶牛生产潜力的发挥,经济效益显著。

| Abstract: | The effect of dietary supplemental nicotinamide(NAM) was investigated on milk performance,blood serum parameters in midlactation high producing dairy cattle.40 high producing Holstein cows in midlactation were randomly divided into four groups.Four levels(0,6,10 and 14 g/d/head) of NAM were supplemented respectively to the basal diet.The results showed that dry matter and protein intake were not affected by addition of NAM(P>0.05).Concentration of Nonesterified fatty acid in blood serum significantly reduce... |
