this study was conducted at beresa watershed district of guraghe administrative zone, the southern regional state of ethiopia to evaluate the on-farm reproductive and egg production performances of local kei and its f1 crosses with fayoumi and rhode island red (rir) chicken breeds under farmers’ management. the local kei paternal line was mated with maternal lines of fayoumi and rir chickens to...
Climate change and disease have large negative impacts on poultry production, but little is known about the interactions of responses to these stressors in chickens. Fayoumi (heat and disease resistant) and broiler (heat and disease susceptible) chicken lines were stimulated at 22 days of age, using a 2x2x2 factorial design including: breed (Fayoumi or broiler), inflammatory stimulus (lipopolys...
The present study was conducted to investigate the variation in the lipid profile between Egyptian breed Fayoumi and commercial strain ISA-Brown. Forty 32-wk-old ISA-Brown and thirty-five 36-wk-old Fayoumi were housed individually in separated layer cages in opensystem housing. Four weeks later, Body weight was recorded and egg weight, number, and composition were measured. In addition, lipid p...
Several studies were conducted on evaluation of heterosis, maternal and reciprocal-effects for different chicken breeds. However, there is a limited information the reciprocal-effect crossbreed Fayoumi White Leghorn. Therefore; this study was designed to evaluate reciprocal effects traits Leghorn from day-old age at first egg. A total six hundred chicks selected,150 each genotype evaluated simu...
Newcastle disease virus (NDV) has a devastating impact on poultry production in developing countries. This study examined the transcriptome of tracheal epithelial cells from two inbred chicken lines that differ in NDV susceptibility after challenge with a high-titer inoculum of lentogenic NDV. The Fayoumi line had a significantly lower NDV load postchallenge than the Leghorn line, demonstrating...
This paper discussed how to optimize production traits for two layer breeds in Egypt. The first breed is indigenous Fayoumi and the second exotic Leghorn. Both breeds have their different performances and each breed was preferred over the other for some particular traits. By crossing the two breeds, the crossbreds could benefit from the strengths of the purebreds for particular traits. The econ...
Kefelegn Kebede, Ashenafi Getachew and Mengistu Urge Two exotic chicken breeds, namely Fayoumi, Koekoek were used in this study to unfold the interdependence among egg quality traits also predict weight from their orthogonal applying principal component regression.
This study was conducted at Beresa watershed district of Guraghe Administrative Zone, the southern Regional State of Ethiopia to evaluate the on-farm reproductive and egg production performances of local Kei and its F1 crosses with Fayoumi and Rhode Island Red (RIR) chicken breeds under farmers’ management. The local Kei paternal line was mated with maternal lines of Fayoumi and RIR chickens to...
Traditional approaches to assess the immune response of chickens to infection are through animal trials, which are expensive, require enhanced biosecurity, compromise welfare, and are frequently influenced by confounding variables. Since the chicken embryo becomes immunocompetent prior to hatch, we here characterized the transcriptional response of selected innate immune genes to Newcastle dise...
