Influence of dietary fat source and copper on broiler performance, fatty acid profile of meat and depot fat, and on cholesterol content in meat

Popis výsledku v původním jazyce

1. Three hundred and twenty d-old chickens were fed on a wheat/maize-soyabean meal diet supplemented with (i) 50 g/kg lard, (ii) 25g/kg lard and 25 g/kg rapeseed oil, (iii) 50 g/kg rapeseed oil, and (iv) 50 g/kg rapeseed oil and 200 mg copper per kg as copper sulphate pentahydrate. 2. Finalweights at 39 d of age on chickens receiving rapeseed oil were lower by 9% than in those fed on the diet containing only lard (p<0.05). The fatty acids profilwas increased and the ratio of n-6:n-3 fatty acids was decreased by the substitution of lard by rapeseed oil (p<0.001). These changes were more pronouced for the adipose tissue than for breast muscles. 4. Copper sulphate supplementation increased the finThe magnitude of improvement, however, was small. 5. The substitution of rapeseed oil for lard decreased the concentration of cholesterol in breast muscles by 13%. Copper supplementation further reduced the cholesterol content by 25%. Both effects were s
