Description
Summary:•Maternal conjugated linoleic acid (CLA) diet decreased the hatchability of fertile eggs.•Maternal CLA diet induced fatty acid catabolism in the liver of offspring embryos.•Soybean oil supplementation alleviated maternal CLA diet-induced loss in egg hatchability and offspring hepatic lipolysis. The objective of the present study was to determine the effect of maternal conjugated linoleic acid (CLA) and soybean oil (SO) dietary on egg hatchability and hepatic lipometabolism in chick embryos. Broiler breeders (36 wk, 3.56 ± 0.12 kg) were randomly assigned to 6 treatments (with 6 replicates per treatment and 25 broiler breeder hens and 1 rooster per replicate) and fed a diet with 0.5% SO (control), or a diet with either 0.5% CLA, or CLA plus 0, 2, 4, 6, or 8% SO for 8 wk, with natural mating. The results showed that 0.5% CLA reduced hatchability of fertile eggs (P
