A crossbreeding experiment was carried out between two local strains of Mandarah (MN) and Matrouh (MA) chicken. Thirty-four sires and 400 dams from each strain were used to produce four genetic groups. Body weights of 3067 chicks at hatch (BW0), 4 (BW4), 8 (BW8), 12 (BW12) and 16 (BW16) weeks of ...

The present study aimed to evaluate some local chicken breed in Egypt. The result indicated that the average of fertility %, hatchability %, body weight at 4 and 8 weeks of age for males, females and combined sexes as well as age at sexual maturity, egg number and egg mass during the first 90 day...
Genetic resistance of native Egyptian breeds to very virulent infectious bursal disease virus (vvIBDV) and Newcastle disease virus (NDV) was investigated in two experiments. In the first experiment, birds from four breeds (Gimmizah, Sina, Dandrawi and Mandarah) were challenged with vvIBDV. The Ma...

Milk Production and milk constituents were studied in 95 ewes of two purebred groups, Ossimi(O) and Saidi (S), and two F1crosses with Chios(C) (CO and CS) from September 1991 to April 1993 at the Experimental Animal Farm, Faculty of Agriculture, Minia University, Egypt. Breed of ewe had an effect (p

Sheep population in Egypt is about 3 million. The three major Egyptian sheep breeds are Barki, Ossimi and Rhamani, Representing 65% of the total population. They are well adapted to local conditions, small to medium size and have a twinning rate ranging from 1.05 to 1.30. A trial for improving pr...
A production system approach was used to study the performance of desert black goat under semi-aird conditions in North Sinai. A random sample of 19 goat breeders was taken. Least squares analysis of variance was performed using fixed effects linear models for all productive traits to develop the...
