Effect of food intake on the gene expression of peroxisome proliferator-activated receptors in F1 follicle of broiler breeder hens

To investigate the involvement of peroxisome proliferator-activated receptors (PPARα, PPARβ/δ and PPARγ) in the reduced egg production of broiler breeder hens with unfit food intake, gene expression of these receptors was evaluated in the granulosa cells of F1 follicle by quantitative real time PCR. Hens (30 weeks old) were allocated to three different levels of feed intake (FI): Control, FI-20% (20% less than control feed intake) and FI% (40% more than control feed intake). These hens were maintained for 30 days with three replicates per group (10 birds / replicate; 30 birds / group). The egg production significantly decreased in two treated groups as compared to control(p
