the experiment was carried out in poultry experimental station belonging to nrc, cairo, egypt. a total of 120 fayoumi layers, 45 weeks old, were randomly divided into four equal groups. each group included three replicates (10 hens in each). the first group was fed the control diet containing 3.3% gram ca, whereas, the other three received diets containing 2.8, 2.6 and 2.4% gram ca, respectivel...

Poultry farming not only provides high nutritious food but also creates employment opportunity for rural masses. Documented evidences elaborates that helminth parasitism is most deciduous problem of chickens especially in developing world. Ascaridia (A.) galli, a nematode of small intestine, has been considered as the most common and important parasite of chicken. The present study was carried ...

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...

Thirty-two Hubbard and 40 Egyptian Fayoumi (dual-purpose) chickens were slaughtered in series at 2-wk intervals between 2-8 wk and 2-10 wk of age, respectively. Genetic differences in the allometric fat growth equation constants were studied. Relative to total body fat (TBF), the breeds did not differ significantly in relative growth of non-carcass fat. The Fayoumi tended to lay down carcass fa...

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...

Egg production data used in this work were obtained from records of Fayoumi chickens flock belongs to El-Takamoly poultry project at Al-Azab, Fayoum Governorate. over a 52-wk egg laying period related 1900 hens. All was summarized on weekly basis as eggs per hen week hen-day (survivor) basis. Regarding Wood and McNally models, (a) stands for initial production, parameter value very low (0.001) ...

The current study is a comprehensive genome analysis to detect QTL affecting metabolic traits in chickens. Two unique F(2) crosses generated from a commercial broiler male line and 2 genetically distinct inbred lines (Leghorn and Fayoumi) were used in the present study. The plasma glucagon, insulin, lactate, glucose, tri-iodothyronine, thyroxine, insulin-like growth factor I, and insulin-like g...

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...

Aim: An experiment was conducted to determine the effect of egg weight on hatchability, embryonic deaths and hatchling weight of three rural breeds (Fayoumi, Desi and crossbred (Rhode Island Red X Fayoumi) chickens. Materials and Methods: Three different egg weight groups classified into small: (<41g), medium (41-45g) and large (> 45g) were used in the experiment. A complete randomized design w...
