Influence of endometritis, cow- and herd-levels factors on milk yield and reproductive performance of zero-grazed dairy cows on smallholder farms in Rwanda

Suboptimal milk production and reproductive performance manifest in postpartum dairy cows likely reflect associations with the characteristics of herd management conditions endometritis infection. The hypothesis was that endometritis, cow- herd-levels variables, combination all these variables are associated suboptimal yield zero-grazed managed on smallholder farms. This research conducted Gasabo district, Rwanda, to farmers from September 2018 August 2019. survey used collect data 370 farms 466 cows, sampled by snowball technique. Regression models general linear model were analysis. results showed a decreasing magnitude, predicted cow breed [regression coefficient (β): −2.6, p
