Abstract

Effect of dietary fat on fatty acid composition of lipids from breast muscle and abdominal fat of broiler chickens

Highlights

The energy density o f broiler chickens diets is high and reaches 12.5-13.4 MJ o f metabolizable energy (ME) per kg of diet
The proportion o f fatty acids (FA) in diet depended mainly on the type o f added fat, the diets supplemented with beef tallow or lard were richest in saturated fatty acids (SFA)
The most polyunsatu rated fatty acids (PUFA) contained the diet supplemented with soya oil, fol lowed by diets w i t h linseed and lard and rape seed oil

Summary

Introduction

The energy density o f broiler chickens diets is high and reaches 12.5-13.4 MJ o f metabolizable energy (ME) per kg of diet. In Polish conditions the main cereal used in broiler diets is wheat, o f relatively low M E value, so the including fodder fat or full-fat seeds is necessary to optimize energy level o f diets. The composition o f fatty acid (FA) in feed influences the composition o f lipids in avian eggs and meat (Leskanich and Noble, 1997). 280 DIETARY FAT FOR BROILERS AND FATTY ACIDS CONTENT IN MUSCLES. The aim o f the study was to compare the effects o f fodder fats o f animal or plant origin and full-fat rape and linseed seeds added to balanced diets on fatty acid composition o f lipids in broiler meat and fat tissues Recent dietary recommendations pertaining to the consumption o f dietary fat in humans have stressed the importance o f lowering the proportion o f saturated to unsaturated FA and the proportion o f long chain n-6/ n-3 polyunsaturated fatty acids (n-6/n-3 PUFA), as it may have beneficial effects on human health.
