this experiment was conducted to evaluate the effects of fennel and thymyus valgaris extracts with and without flaxseed on performance and egg quality of laying hens (hy line w-36). the experiment was conducted in a completely randomized design with 200 laying hens in 5 treatments and 5 replicates (with 8 hen in each replicate) for 12 weeks. the hens were fed isocaloric and iso nitrogenous diet...

The aim of this investigation was to assess the effect of different antioxidants on the motility andmembrane integrity of the ram semen during storage at 5ºC for 0, 12, 24, 48 and 72 hrs after collection anddilution. A total of 57 ejaculates from 12 Bakhtiary rams was collected by artificial vagina and were extended1 : 3 with egg yolk-citrate buffer, which was containing one of the following an...

this study aimed to decrease the cholesterol content of egg yolk of laying hens through inclusion of barley malt rootlets in the diets. forty-two, 54-week-old, lohman laying hens were fed for a 12 weeks laying period on 3 iso-caloric and iso-nitrogenous diets contained 0 (control), 25.5 or 51.1g barley malt rootlets/kg. inclusion of barley malt rootlets at 25.5 or 51.1g/kg diet significantly de...

Three artificially inseminated laying White Leghorn hens were given 35-50 micro c of cholesterol-4-(14)C intravenously. Their subsequently produced eggs contained cholesterol-(14)C-labeled yolks. Some of the fertilized eggs were analyzed for cholesterol content and radioactivity. Other eggs were incubated until hatching. The specific activity of the cholesterol contained in the serum and tissue...
