COMPARATIVE ANALYSIS OF THE ONTOGENETIC DYNAMICS OF MORPHOMETRIC AND PRODUCTIVE INDICATORS OF GOOSE BREEDS OF DIFFERENT MEAT PRODUCTIVITY DIRECTIONS

Abstract

The relevance of this article is determined by the necessity of developing goose breeding in the agricultural sector of Kazakhstan and ensuring the population with high-quality meat products. In this context, to reduce dependence on imports and increase the competitiveness of domestic products, the prompt improvement of the genetic base of poultry farming acquires significant importance.

The aim of the work is to conduct a comparative analysis of the dynamics of live weight gain of meat-type goslings (linda, chinese white wanxi, and hungarian heavy) up to 90 days of age, determine their productive potential, and provide scientifically grounded recommendations for selecting the most effective breed under the climatic and economic conditions of Kazakhstan. The study was carried out at the only breeding reproducer for breeding geese in the Republic of Kazakhstan, located in the West Kazakhstan region.

The results showed that Linda goslings demonstrated the highest live weight gain and intensity of average daily growth during the rearing period from 1 to 63 days. By the total absolute gain up to 90 days, Linda geese surpassed the other breeds by 3.7% – 4.7%. Furthermore, due to the sharp deceleration of growth in all breeds, the economic feasibility of fattening goslings up to 63 days was justified.

In conclusion, the research results recommend the Linda breed as the most effective solution for meat poultry farming in Kazakhstan, which contributes to the improvement of selective breeding work and the strengthening of the scientific and practical base of goose breeding in the country
