Effects of clofibrate treatment in laying hens.

Expression of peroxisome proliferator-activated receptor-alpha (PPARalpha) has been shown in liver of chicks, but effects of its activation have not yet been investigated. In this study, laying hens were treated with clofibrate, a synthetic PPARalpha agonist, to investigate the effects of PPARalpha activation on liver lipid metabolism. Hens receiving a diet containing 5 g of clofibrate/kg had a...

Effects of Fennel Extract on Egg Production, Antioxidant Status and Bone Attributes of Laying Hens Administered Carbon Tetrachloride

This study was conducted to investigate the effects of fennel ethanol extract on egg production, serum parameters, and bone attributes of laying hens administered carbon tetrachloride (CCl4). A total of 192 Hy-Line W-36 laying hens were assigned to four treatments of four replications in a completely randomized design for 9 weeks (36-44 weeks of age). Experimental groups consisted of 1) positiv...

Effects of housing, perches, genetics, and 25-hydroxycholecalciferol on keel bone deformities in laying hens.

Several studies have shown a high prevalence of keel bone deformities in commercial laying hens. The aim of this project was to assess the effects of perch material, a vitamin D feed additive (25-hydroxyvitamin D(3); HyD, DSM Nutritional Products, Basel, Switzerland), and genetics on keel bone pathology. The study consisted of 2 experiments. In the first experiment, 4,000 Lohmann Selected Legho...
