背景:牛奶的微生物量是决定牛奶质量的一个主要因素，它表明了挤奶器具的清洁度、储存条件、运输方式以及个体动物乳房的清洁度。本研究的目的是测定牛奶的微生物质量。方法:本研究在阿姆哈拉民族地区州奥罗米亚地区的达瓦切法区进行。上午从酒店(27个样品)、合作社(3个样品)和家庭生产者(20个样品)共收集了50个生牛奶样品。参与研究的农民(生产者)是根据牛奶生产潜力、市场导向和家庭意愿选择的。每个采样点在一个月内抽取两次生晨奶样本。在收集过程中，从所有者的容器中无菌地取出约250毫升生牛奶样本，然后放入无菌玻璃瓶中。结果:从奶农、乳品合作社和酒店采样的牛奶平均总盘数分别为6.88 log10、7.10 log10和7.54 log10。农场水平的平均大肠菌群数量为5.57 log10，乳品合作社为5.63 log10，酒店为5.37 log10。农民、乳品合作社和酒店的平均酵母和霉菌数量分别为0.46 log10、0.62 log10和0.74 log10 cfu/ml。 The indirect tests and the actual bacterial count indicated that the microbial quality of milk produced by farmer and collected by dairy cooperatives in the study area was poor and this calls for scrupulous hygienic measure during production and handling of milk. Conclusion: The result showed that the microbial quality of raw milk obtained from local dairy farmer was very low. This was due to the unhygienic condition of milking; unclean milk handling equipment and the use of contaminated water. Therefore, Proper hygienic practice will become a useful parameter and model for other dairy farmers within the district to improve and upgrade their dairy production.
