METHOD FOR MATCHING PARENTAL PAIRS ON INCREASED NATURAL RESISTANCE, STRESS-RESISTANCE AND PERFORMANCE QUALITIES IN OFFSPRING

摘要

FIELD: agriculture, poultry.;SUBSTANCE: one should select males and females by the value of biological potential being average and above average. To obtain stress-resistant offspring at different level of resistance one should carry out heterogeneous selection at applying males at the value of biological potential being higher against females. The innovation provides natural resistance, stress-resistance and performance qualities in offspring.;EFFECT: higher efficiency of matching.;1 dwg, 4 ex, 5 tbl
