  • Abstract


    The purpose of the research is comparative evaluation of fertilizing ability of cocks-breeders in absolute rates (arithmetic mean) and relative (probit), held at egg-laying hens of “Kuchinsky” PBP. Fertilization of eggs, hatchability of eggs and poultry rearing were taken into account during evaluation. Evaluation of cocks in terms of incubation qualities showed that eggs fertilization was 81.4%, hatchability of eggs – 76.6% poultry rearing – 62.4%. On average one cock fertilized 194.8 eggs, from which 149.3 poults were reared. Biometric processing of incubation qualities identified that influence of cocks was reliable (r > 0.999) on all three indicators, and hatching quality were interconnected, the coefficient of multiple correlation was on the level of 0.939 (p > 0.999). Comparative evaluation and selection of cocks in absolute terms and with the help of probit-method confirmed high coincidence of their ranks. Rank correlation coefficients between evaluations of these 2 methods of eggs fertilization, hatching and poults rearing was at the level of 0.999–1.000.
