OBJECTIVE To study the harmful effects of nicotine on the developing femur of chick and to observe the role of antioxidant camellia sinensis in the prevention of these effects. METHODS The experimental study was conducted at Army Medical College, Rawalpindi, from November 2, 2011, to November 1, 2012, and comprised fresh fertilised eggs of Fayoumi species at zero hour of incubation of Fayoumi...

Molecular genetic selection on individual genes is a promising method to genetically improve economically important traits in chickens. A resource population was developed to study the genetics of growth, body composition, skeletal integrity, and metabolism traits. Broiler sires were crossed to dams of 2 diverse, highly inbred lines (Leghorn and Fayoumi), and the F1 birds were intermated by dam...

Nutritional modulation of the immune system is an often exploited but poorly characterized process. In chickens and other food production animals, dietary enhancement of the immune response is an attractive alternative to antimicrobial use. A yeast cell wall component, beta-1,3/1,6-glucan, augments the response to disease in poultry and other species; however, the mechanism of action is not cle...

This study was carried out at El Takamoly Poultry Project, Fayoum, Egypt,. A total number of 498 (450 breeder hens and 48 cocks) birds of Golden Montazah (GM) and Fayoumi (F) strains at 42 wks of age were used to evaluate the effects of two dietary levels of Se as Sel-Plex (0.1 or 0.2 mg/Kg diet) on breeder hens performance. Birds were divided randomly into 3 equal treatment groups of 83 birds ...

Electroencephalographic characteristics and clinical symptoms of an avian genetic reflex epilepsy have been transferred from Fayoumi epileptic (Fepi) chickens to non-epileptic chickens by embryonic homotopic grafts of brain neuroepithelium. Transplanted tissues belonging to the prosencephalic vesicle transferred epileptic electrical features while tissues from the mesencephalic vesicle were res...
