Laboratory and Patohistological Diagnosis of Fatty Liver in Cattle in the Peripartal Period

Abstract

Peripartal period of dairy cows is characterized by the appearance of numerous metabolic diseases and their impact on the quality and cost-effectiveness of production. Fat accumulation in liver is a common finding in cows during late pregnancy and in the first three weeks of lactation. A fatty liver represents a disorder of metabolism of fat and carbohydrates, and is conditioned by a negative energy balance. All categories of dairy cows, especially obese cows and cows with a long service period, are predisposed. The main preventive measure is the optimization and use of balanced meals in quantitative and energy terms during the period of drying and early lactation.

Peripartalni period mlečnih krava se karakteriše pojavom mnogobrojnih metaboličkih bolesti i njihovim uticajem na kvalitet i ekonomičnost proizvodnje. Nakupljanje masti u jetri je čest nalaz kod krava za vreme kasnog graviditeta i u prve tri nedelje laktacije. Masna jetra predstavlja poremećaj metabolizma masti i ugljenih hidrata, a uslovljen je negativnim energetskim bilansom. Predisponirane su sve kategorije mlečnih krava, a posebno gojazne krave i krave sa dugim servis periodom. Kao osnovna preventivna mera navodi se optimizacija i korišćenje izbalansiranih obroka u kvantitativnom i energetskom smislu tokom perioda zasušenja i rane laktacije.
