Preservation and improvement of the gene pool of waterfowl in order to create new domestic crosses and evaluate the original lines of families in crosses, in order to identify their compatibility according to the main economically useful characteristics

Abstract

This paper presents the results of scientific research on the economically useful qualities of ducks of the collection herd of the “Bishkek Poultry Farm” LLP. Breeding work with ducks was based on the methods and techniques used in working with meat poultry (chickens, ducks, turkeys, geese, etc.). However, they took into account their own specific features of ducks and differences due to the biological qualities of this bird species (features of growth and development, excessive obesity of the carcass, narrow sex ratio, organization of nesting productivity accounting). In the structure of the progenitor and parent herds, there may be 20-40% of overfed ducks, the level of productivity of which is quite high in the second cycle of egg laying. After forced molting, more ducklings can be obtained from the duck of the parent flock than in the first egglaying cycle, although the total egg-laying rate is slightly lower in the second cycle. For the year-round receipt of incubation eggs, and therefore the uniform production of duck meat throughout the year, multiple (three-fold) recruitment of the parent herd is carried out. The parent herd is formed at the age of 150 days. The ratio of drakes and ducks is 1:4. Thus, among the collection herd, we have discovered ways to preserve and improve the gene pool of waterfowl by increasing their productivity.
