Influence of males of the paternal line with different weight index on the productivity of rabbits of the maternal form of the Hyla Cross

The maternal form of modern rabbit crosses is obtained by crossing ancestral lines. Therefore it relevant to investigate the effect using males parental line Hyla cross with different weight indices on performance main breeding traits female rabbits cross. purpose study was level productivity reproduction signs and consider dynamics for a number births. experiments used 223 cross, which came from indices. To achieve this goal, groups were formed, depending value their father's Index – Group 1 ≤ 100 units, 2 120 3 ≥ units. live after kindling, multiparity, newborn rabbits, milk yield, at time weaning determined. Female that high index first kindling significantly outnumbered peers in multiparity 1.16-1.23 animal units (p 0.05), yield 6-6.5%. Rabbits whose parents according results 3rd prevailed over other also had higher values complex (p≤0.05). From 1st increases, average, 6.5%. Live birth Groups positive trend increased 3.2% 4.2%, respectively. On 38.6% third kindling. practical significance lies fact obtain highly productive form, advisable use
