A study was conducted to determine the effect of breed, sex and diet on the carcass composition of chickens. Male and female chicks of the Light Brahma, White Plymouth Rock, Single Comb White Leghorn, Black Jersey Giant and Dark Cornish breeds were fed three diets of widely varying calorie:protein ratios to four weeks of age. The Black Jersey Giant chickens attained the greatest weight at 4 weeks followed by the White Plymouth Rock, Dark Cornish and Single Comb White Leghorn with the Light Brahma growing the slowest of the strains tested. Significant differences in the quantity of moisture, protein, total lipid and ash present in the total carcass was found among certain breeds. The Light Brahma contained the largest amounts of total lipid, 10.4%, followed by the White Plymouth Rock, 10.2%, Black Jersey Giant, 9.5%, Single Comb White Leghorn, 8.8%, and the Dark Cornish, 8.6%. Both sex and diet also caused differences in the total body composition. Significant differences in the amounts of certain fatty acids in the carcasses of the various breeds were found; however, these differences were not great.
开展了一项研究以确定品种、性别和饮食对鸡胴体组成的影响。将浅花婆罗门鸡、白普利茅斯洛克鸡、单冠白来航鸡、黑泽西巨人鸡和暗康沃尔鸡的雄性和雌性雏鸡饲喂三种热量：蛋白质比例差异很大的日粮至4周龄。黑泽西巨人鸡在4周龄时体重最大，其次是白普利茅斯洛克鸡、暗康沃尔鸡和单冠白来航鸡，浅花婆罗门鸡在测试的品系中生长最慢。在某些品种之间，发现整个胴体中的水分、蛋白质、总脂质和灰分含量存在显著差异。浅花婆罗门鸡的总脂质含量最高，为10.4%，其次是白普利茅斯洛克鸡，为10.2%，黑泽西巨人鸡为9.5%，单冠白来航鸡为8.8%，暗康沃尔鸡为8.6%。性别和饮食也会导致全身组成的差异。在各个品种的鸡胴体中发现某些脂肪酸的含量存在显著差异；然而，这些差异并不大。
