萨能奶山羊乳体细胞数与乳汁成分变化的研究

Abstract

Abstract: In this study, in order to study the effect of the somatic cell count (SCC) on the main composition and content of goat milk, somatic cell were collected and analyzed of Sanne-goat by using DHI method, which could provide the reference for raw milk product quality evaluation. The results showed that the SCC had no significantly positively related with milk fat percentages (P=0.141), and were significantly positively related with milk protein percentages (P<0.01). The content of lactose was significantly negatively related with SCC (P<0.01).The content of total solids was highly significantly positively related with SCC (P<0.05).The content of urea nitrogen was highly significantly negatively related with SCC (P<0.01). Rising of SCC could greatly affect the quality of goat milk, induce the increase of milk protein percentage, milk fat percentage and the content of total solids and the decrease of the contents of lactose and urea nitrogen. In summary, the somatic cell count and the portion of milk components in June could be used as reference to evaluate the quality of Sanne-goat milk.

Key words: Sanne-goat; somatic cell count; goat milk; quality
