Abstract

: The present experiment was carried out in the Poultry Farm, Department of Poultry and Fish Production, Faculty of Agriculture, Menoufia University at Shibin El-Kom, Egypt. The local strain used was Sinai Bedouin fowl. The experiments lasted for four years, starting from October 2014. The aim of the experiment was to study the response of selection for high protein efficiency (g protein/g egg) of laying Sinai hens. Protein efficiency for egg production during the first 90 days of production was calculated according to : 1. Protein efficiency (g Protein / g egg) = (Selected trait) The average protein efficiencies were 0.770 ± 0.159, 1.001 ± 0.452 and 0.670±0.171 in the first, second and third generations, respectively. The actual genetic responses to selection for protein efficiency were obtained. The selection responses were -0.081, -0.132 and -0.528 (g) in the first, second and third generations, respectively. The calculated heritability for protein efficiency g protein per 1 g eggs was 0.12
