摘要/Abstract

摘要： 乳汁体细胞数(somatic cell count,SCC)是检查奶牛乳房炎和牛奶质量的指标,为了解南宁某规模化奶牛场奶水牛SCC情况及SCC与其他乳成分的关系,试验随机选取该场152份泌乳早期乳样,测定其SCC、乳汁比重、蛋白质、脂肪、总固形物、非脂固形物及乳糖的含量,并对其进行相关性分析。结果表明,SCC小于50万/mL的乳样占被检奶样总数的88.16%,大于100万/mL的占1.97%;乳汁比重、乳蛋白、乳糖和非脂固形物含量均随着SCC的升高而下降,而乳脂含量随着SCC的升高而呈上升趋势;SCC与乳糖及非脂固形物含量呈极显著负相关(P<0.01)。因此,奶水牛乳中SCC不仅与乳糖和非脂固形物含量密切相关,也提示其与奶水牛产后营养代谢状况有关。

Abstract: Somatic cell count (SCC) is a test parameter for bovine mastitis and milk quality. In order to understand the correlation between SCC and some milk components in one buffalo dairy farm in Nanning area, 152 fresh milk samples at early lactation stage were randomly chosen and SCC, specific gravity(SP), protein, total solid and nonfat solid, lactose levels of milk were determined, correlation among them was analyzed. The results showed that 88.16% of samples had SCC less than 50×10⁴/mL, 1.97% of samples had SCC more than 10×10⁵/mL. SCC had an increasing trend with milk fat, but SCC had an increasing trend with the decrease of milk SP, milk protein, lactose, and nonfat solid level. There was a extremly significant negative correlation between SCC and lactose, between SCC and nonfat solid (P<0.01). In conclusion, SCC was not only significantly related to the milk lactose and nonfat solid level, but also associated with metabolic status of dairy buffalo cows postpartum.

Key words: dairy buffalo cows; somatic cell account; correlation; milk component
