Abstract

The study was done on 14 cocks and 14 hens of the Dokki 4 bread 21 weeks of age. The first trial was conducted to atte mpt the application of amino benzene dilution method in the estimation of body water content. Two mls. of amino benzene (10)% were injected in each cock or hen, then 1 ml. of blood was taken after 1/2 or 1 hour from the injection estimated moisture values from samples taken after one hour from injection showed a high degree of accuracy. It is concluded that taking blood samples after half an hour is not enough for uniform distribution of amino benzene in the body fluids.
The second trial was conducted to study the relationships bet ween the major components of the fowl carsass. It was found that there is an inverse linear relationship between fat and water, and fat can be estimated from water content using the linear equa tions Y = 33.0316 - 0.3850 X (in cocks) and Y= 39. 6493 0.4538 X (in hens). The body protein can be estimated using its constant percent in the fat free dry carcass (77.34% in cocks and 78.28% in hens) or the constancy of the combined protein and fat value in dry carcass (81.71% in cocks and 3.97% in hens). The results showed that there is no sex difference except in the HO: fat ratio
