Bacterial Composition and Interactions in Raw Milk and Teat Skin of Dairy Cows
نویسندگان
چکیده
The microbiota in raw milk plays an important role the health of dairy cows and safety products, which might be influenced by that teat skin. However, composition skin, as well bacterial interaction between two adjacent spatial locations, remains elusive. Here, we investigated composition, diversity, co-occurrence network communities on shift during bath using 469 samples from 156 individual cows. We observed skin harbored significantly different according to assessment genera numbers (p < 0.05) PCoA analysis (ANOSIM p 0.05). was dominated Proteobacteria (58.5% relative abundance) at phylum level Pseudomonas (51.2%) genus level, while Firmicutes (46.9%) (11.0%) level. a massive difference subnetworks teat, abundance these locations positively correlated Using Bayesian algorithms, identified 92.1% bacteria were transferred 63.6% milk. Moreover, could affected with iodine disinfectant, tended more similar after 0.05), dominant increased These findings expand our knowledge milk, locations.

The present study was conducted to evaluate the effects of using raw or microwave irradiated safflower seed on dry matter intake, milk production and composition, milk fatty acid profile, blood parameters, and nutrient apparent digestibility in early lactation cows. Nine multiparous Holstein cows at early lactation were randomly assigned to one of three treatments based on 3 × 3 balanced latin ...
