Abstract: According to the results of the study of indicators of the productivity of
rabbits of different breeds when using industrial crossbreeding, which was carried out
based on the experimental rabbit farm of the Cherkassy research station of bioresources of
the National Academy of Sciences of the Soviet Chinchilla breed of female rabbits and gray
males, it was established that under the conditions of intensive rabbit production, the reproductive qualities of Soviet chinchilla female rabbits the combination with males of the
gray giant, New Zealand white breeds increases by 10-15%. Also, the use of Soviet chinchilla female rabbits in industrial crossbreeding, and gray giant and New Zealand white
males as parental males, allows for increasing the maternal indicators of female rabbits,
fattening, and meat productivity indicators of the obtained young rabbits. The best indicators of fattening and meat productivity in young animals were established during interbreeding of rabbits of the studied groups with a probable superiority over animals of purebred breeding - fattening indicators: live weight at 90 days of age by 4.0; 3.8% (p<0.05); average daily increases of 4.7-5.4% (р<0.05...0.01); waist width by 5.6-8.7% (р<0.01).
Keywords: female rabbits, crossbreeding, productivity, reproductive capacity, breed, fattening young.
