Abstract. The purpose of the studies was to assess the formation of signs of meat productivity in goslings of various genotypes in postnatal ontogenesis. The work was performed at the poultry farm Agro-Gus Ural on birds of Large Grey and Hungarian breeds as well as on hybrid young birds bred by crossing White Hungarian male geese with Large Grey female geese. For the experiment, one-day-old goslings were divided into three groups by the analogue method based on live weight and development. Each group consisted of 250 males and 250 females. Hybrid males exceeded the parent male birds in survival rate by 2.4%, in live weight at the age of one day – by 13.2% (p was less than 0.05), in final weight – by 22.9% (p was less than 0.001), in absolute gains over the growing period – by 23.1% (p was less than 0.001), and in average daily increments – by 23.1% (p was less than 0.001). We registered a tendency of superiority for parent female peers for the same indicators by 4.4%, 8.1%, 13.6%, 13.7%, and 13.7%, respectively. The survival rates of hybrid females were 2.8% higher, in comparison with the parent male birds; their live weight at the age of one day was 15.6% higher (p was less than 0.05); their final weight was 17.7% higher (p was less than 0.001); their absolute gains were 17.8% higher (p was less than 0.001), their average daily live weight gains were 17.8% higher (p was less than 0.001); these indicators were higher than those of parent female birds by 4.0%, 8.7%, 10.4%, 10.5%, and 10.5%, respectively. The meat productivity index for the hybrids was 214.1%; for females, it was 194.2%, which was higher than the value of the same indicator among the peers of the male-parent breed by 32.6% and 15.8%, respectively, and among the peers of the female-parent breed by 24.3% and 10.7%, respectively.
