Abstract

    The present study was designed to evaluate the effects of high dietary fat on serum cholesterol and fatty liver syndrome in broilers. For this purpose, 90 day-old chicks were divided into three equal groups A, B and C. Group A acted as control. The birds of group B were fed on diet containing vegetable fat while birds of group C were fed on diet containing animal fat. It was observed that the serum cholestrol values in chicks of groups B and C were higher than those of the control group. Furthermore, the serum cholesterol value was higher in birds of group C than group B. Grossly, the livers of birds of  groups B and C were enlarged, pale in colour, soft in consistency and were having petechial haemorrhages with fat and fibrin deposits. Histopathologically, livers of groups B and C showed fatty infiltration, haemorrhages and mass of eosinophilic materials. The vacuoles coalesced to create clear space that displaced the nucleus to the periphery of the cell. It was concluded that addition of dietary fat from animal and vegetable sources in the diet of broiler chicks not only resulted in increase in serum cholesterol but also in marked macroscopic and microscopic changes in liver. 

Key words:  Dietary fat, serum cholesterol, fatty liver syndrome, broilers.
