INFLUENCE OF DIRECTIONAL SELECTION ON PRODUCTIVE AND MEAT QUALITIES OF DUCKS OF THE TEMP CROSS

Abstract

The paper presents the results of the research on the influence of directional selection on productivity of ducks and meat qualities of line and hybrid ducks of three generations. The use of the estimation system of ducks allows increasing egg laying capacity of ducks by 4.9–6.3 %, hatching rate by 2.0–3.6 points, live weight of ducklings by 6.1 %, weight of a carcass – by 8.5 %.
