Chicken egg incubation results and growth rate of crossbreed chickens

Relevance . Poultry farming is one of the promising sectors agriculture. High growth rate and good meat quality are main factors in breeding. A convenient tool for studying phenotypic characteristics breeds crosses, as well genetic new breeding forms, creation model animal populations. Methods The aim this study was to obtain first-generation crossbreeds from crossing egg meat-egg chicken breeds, order evaluate incubation results compare them with source development rates obtained chickens’ hybrids. In experiment, we used poultry Russian white egg-production Pushkin functions. Starting day chicks were hatched a period once week measure taking weight chickens carried out. addition, starting first life, linear measurements, such body length, depth, width chest circumference, out month. dynamics evaluated before onset maturity oviposition females. Results Fertility eggs during interbreed insemination 81%, which differed indicators within parental by an average 10%. hatchability less 35.89 43.23% (p < 0.05) comparison breeds. Upon reaching at age 5 months, mass females 1554.8 ± 111.72, males — 1916.9 63.88 g, relative increase, showing intensity gain over entire period, 189.6% 191.6% respectively. Thus, individuals cannot compete initial their productive qualities practical production. However, generation can be create population second generation, it will possible determine associations genes economically useful traits diversity.
