小叶章青干草对乳牛产奶量的影响

EFFECT OF GREEN DRIED DEYEUXIA ANGWSTTFOLIA ON THE MILK PRODUCTION OF DAIRY COWS

为探讨小叶章青干草对乳牛产奶量的影响效果,选择胎次,泌乳月、日平均产奶量近似的7对黑白花泌乳牛,采取单因子配对法分为试验组和对照组,进行小叶章青干草(试验组)与玉米秸和大豆荚皮合用(对照组)饲喂奶牛的对比试验。结果小叶章青干草较玉米秸和大豆荚皮合用营养价值高,适口性好,增产效果明显。试验组牛日平均产乳量和标准乳量较对照组分别提高5.22和4.36公斤。

Seven pairs of the black and white lactating dairy cows similar in the parity, lactating month and average daily milk production were divided with the single factor pairing method into the experiment and control groups to investigate the effect of the green dried Deyeuxia Angwstifolia on the milk production of the dairy cows.The comparative feeding experiments of the green diried Deyeuxia Angwstifolia (GDDA) (experiment) and the combination of corn stem and soybean pod (CSSP) (control) to the dairy cows were conducted .The result indicated that the nutritive value and palatability of GDDA were better than those of CSSP.The effect of GDDA on increasing milk production was obvious.The milk production of the experiment cows and standard milk production were 5.22 and 4.36kg higher than that of the control cows, respectively.
