Dietary CLA alters yolk and tissue FA composition and hepatic histopathology of laying hens
Authors:
Abstract
The effect of dietary CLA along with n‐3 PUFA on yolk FA profile and hepatic lipid accumulation was investigated. Laying hens (n=40) were randomly assigned to four experimental diets containing 0, 0.5, 1.0, or 2.0% CLA. Menhaden oil was used as the source of n‐3 PUFA. Dietary CLA did not affect the total lipid content of egg yolk (P>0.05). The amounts of CLA isomers (cis‐9 trans‐11, trans‐10 cis‐12) in the egg yolk were proportional to the levels of CLA in the diet (PPPPPPPP0.05). The current study used CLA in a FFA form. The effects of using CLA in other form such as TG on avian hepatic tissue need to be investigated.Keywords
