以伊犁河谷地区昭苏马场的36匹伊犁马为研究对象,并采集其泌乳期的产奶量,利用乳成分测定仪测定马匹的乳脂率,分析乳脂率的影响因素,通过响应曲面的分析获得最佳变量水平.采用Box-Behnken Design响应曲面法对影响乳品品质的因素、不同胎次、不同时间段和不同泌乳月份进行探讨.结果表明在伊犁马第8胎次、采样时间点为16时、泌乳月份为8月时,乳脂率为最佳水平,为1.01%,为乳品质的选择提供基础参考.
The paper studies 36 Ili horses from Zhaosu Horse Farm in Yili River Valley through collecting their milk yield during their lactation period, measuring their butterfat content by using of milk component tester, analyzing the factors that affect butterfat content to obtain the best variable level via Response Surface Methodology, and discusses the factors that affect milk quality in different parities, period, and months of lactation by means of Response Surface Methodology of Box-Behnken Design, and it is concluded that the butterfat content of 1.01% is the best when Ili horses have 8th fetus with the sampling time of 16:00 and in August as their lactation period, which provides basic reference for the selection of milk quality.
