Carcass Quality of Fattening Laying-Type Cockerels

Popis výsledku v původním jazyce

Laying-type cockerels in most countries with developed poultry industry are killed immediately after hatching and they are regarded as waste, which is very unethical. Fattening of the cockerels could be an alternative to their killing after hatch. Therefore an experiment was conducted. Males of four laying-type DOMINANT hybrids from the company Hatchery Studenec, s.r.o. were used in the experiment, 200 cockerels of each hybrid. Cockerels were fattened on litter until 18 weeks of age. At the age 12 and 18 weeks the carcass yield and carcass quality of 10 cockerels of each hybrid were evaluated. At 12 weeks of age there was no significant difference (P>0.05) among the hybrids in live body weight, carcass weight, and thigh and breast muscle proportion of carcass. The highest carcass yield was found in D 853 hybrid. At 18 weeks of age the highest live body weight and carcass yield was in hybrid D 853. Anyway there was no significant difference in breast yield among the hybrids. The significantly lowest thighs proportion was found in the hybrids D 109 (P<0.05).
