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 ...

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...

The mode of ownership of chicken in the family was various types, for instance shared ownership constituted about (57%) followed by individual ownership (43%) among the members of the households. More than around 70% of overall care-taking of chickens, feeding of chickens, cleaning of birds-quart...

The policy analysis matrix (PAM) approach was applied to assess the competitiveness of poultry and pig production (using local, crossbred and exotic breeds) in North and South Vietnam using data collected in 1999 from a stratified sample of 2213 farms. Results show that poultry meat and egg produ...
