摘要: 旨在探讨内蒙古自治区呼伦贝尔地区不同月份荷斯坦奶牛乳成分、体细胞数和菌落总数的变化情况。试验共采集2019年1-12月14 354批次样本进行分析,以探索不同月份对奶牛产奶量、乳成分、体细胞数和菌落总数的影响。结果表明:呼伦贝尔地区荷斯坦奶牛产奶量在不同月份有变化,4-5月达到最高值,11月到次年2月最低,建议在该阶段做好奶牛冷应激防护;体细胞数在1-3月比较高,建议加强奶牛饲养管理,注意乳房炎防控;乳成分和菌落总数基本不受月份变化影响。

Abstract: The purpose of this study was to characterize the inter-monthly variation of milk composition, somatic cell count and total bacterial count in Holstein dairy cows in Hulun Buir region of Inner Mongolia. A total of 14 354 batches of samples were collected from January to December in year 2019 and used to assess the variations of milk yield, composition, somatic cell count and total bacterial count in different months. The results showed that the milk yield of Holstein dairy cows in Hulun Buir region had an obvious inter-monthly difference; the highest milk yield was observed from April to May; the lowest milk yield was observed from November to February of the following year, and protective measures against the cold stress were recommended in this duration; higher level of milk somatic cell count was observed from January to March, accordingly, the feeding management of dairy cows was expected to be strengthened, and the prevention and control measures against mastitis was supposed to be taken; milk composition and total bacterial count hardly varied among different months.

Key words: Hulun Buir region, months, milk yields, milk composition, somatic cell count, total bacterial count
