不同胎次放牧伊犁马产乳性能及乳品质相关性研究
The Correlation Study of Mare′s MilK Performance and MilK Quality of Different Parity Grazing Yili Horses
摘要
Abstract
Objective] The project aims to explore the lactation performance and provide reference basis for the development and utilization of the mare′s milk products by mastering the changes of daily milk yield and composition of nutrition in Yili horses with different parity.[Method]The relation between the milk yield and milk protein and between the solid mater and milk fat,milk protein,milk lactose were analyzed by means of software SPSS18.0,and the regression equation was constructed using stepwise regression analysis.[Result]The nutrition in seventh —parity was lower than that of the others (milk fat 1.3%,milk protein 1.66%,milk lactose 5.86%,the solid mater 9.3%),but the mare′s milk yield was the highest (12.49L).The nutrition in fourth —parity was higher than that of the others (milk fat 1.35%,milk protein 1.82%,milk lactose 6.13%, and thhe solid mater was 9.77%).The regression model between the milk yield and milk protein and between the solid mater and milk fat,milk protein,milk lactose were built,Ymilk yield =840.157 —106.073Xmilk protein , Ysolid mater =—0.147 +1.187Xmilk lactose +0.803Xmilk fat +0.864Xmilk protein.[Conclusion]It showed that the parity had significant effects on the nutrition and mare′s milk yield (P ﹤0.01),and there was a certain correlation between milk yield and milk composition and milk composition by analyzing of the correlation between different indexes.关键词
