【摘要】 将泌乳期奶山羊３０只均分为试验组和对照组，试验组添加“３６９”牛羊高效增乳剂。结果表明，该增乳剂具有显著增乳效果，试验组日均产奶量高于对照组２１．６％（Ｐ＜０．０１）。两组间乳脂、乳糖和乳蛋白含量均无显著差异（Ｐ＞０．０５）．试验组ｃＡＭＰ和ｃＧＭＰ明显升高，增长率分别达４０．７％和４７．１％，与对照组相比差异极显著（Ｐ＜０．０１），且与产奶量正相关（ｒ＿（ｃＡ）＝０．９２１，ｒ＿（ｃＧ）＝０．９０３）．甲氧氯普胺在乳中残留量很低，平均１．６１μｇ·ｍＬ￣（－１）试验组隐性乳房炎阳性率显著低于对照组（Ｐ＜０．０１）。更多还原

【Abstract】 Thirty Saanen milking goats are divided into two groups,the treatmentgroup and the control group , with the former treated with the 369 High Efficient milk-increase Additive. The results show that the treatment group yields 21.6%more thanthat of the control group（P<0.01）. The contents of milkfat ,lactose and lacoproteinbetween the treatment group and the control group exhibit no remarkable differences(P>0.0 The increase rates of cAMP and cGMP in the treatment group are 40.7%and47.1%, respectively,remarkably higher than that of the control group（P<0.01）,andpositively correlated with the milk yield (r_cA=0.921 and r_cG=0.903).The residue ofMCP in milk is very low with an average value of 1.61μg·mL￣（-1）.In addition,the in-crease rate of subclinical mastitis in the treatment group is remarkably lower than thatof the control group（P<0.01）.更多还原
