milk microbes

In-depth study of whether microorganisms contained in pasture environment have an impact on microorganisms in raw milk is essential to improve the safety quality of raw milk and its potential impact on human health. Because Yunnan, China, is located on the plateau(elevation 2000 m) and has no obvious four seasons, while its spring is dry and autumn is rainy. Therefore, in this study, a total of 34 spring samples (10 environments, 12 nipples, two samples of raw milk, eight samples of forage and two samples of drinking water) and 50 autumn samples (11 environments, 14 nipples, nine samples of raw milk, five samples of forage, six samples of dung and five samples of biogas residue) were sampled for further study. The taxonomic composition was evaluated to determine the impact of pasture environment on the microbiota structure in raw milk.
