[Study of hepatic steatosis at the start of lactation in dairy cows consuming grass silage].

Abstract

A survey of the incidence of post-parturient fatty liver in high yielding dairy cows was carried out on 74 cows from 34 dairy herds fed grass silage. Triglyceride determination in liver biopsies indicated that 20% of the cows had a moderate or severe fatty liver between 5 and 21 days postpartum.
