The results of the research found that the highest multiplicity was characterized by rabbits of the Californian breed during crossbreeding with male breeds of Pannon white and New Zealand white. Although the difference is detected and unlikely, they exaggerate the purebred rabbits of the New Zealand white breed by 0.5 and 0.4 heads. The use of

Californian and New Zealand white breed male breeders when breeding rabbits of white pannon breeds did not contribute to the increased multiplicity of rabbits and other reproductive qualities, the difference between all indices is unlikely.

In order to improve the reproductive performance of high-yielding rabbit breeds, it is expedient to use the following two- and three-breed combinations: Kl × PnB and Cl × NzB; 1⁄2Kl1⁄2NzB × PnB and 1⁄2Kl1⁄2PnB × NzB.

According to the indicators of fattening signs, the best combination was 1⁄2Kl1⁄2PnB × NzB. Fledglings spent on picking and fattening at 0.6 kilos. less than pure-born peers. The age of reaching the maturation condition decreased by 6.3 days, and the average daily increase increased by 6.0 g. The probable difference was also observed in the combination of 1⁄2Kl1⁄2NzB × PnB.

Consequently, the results of industrial crossbreeding guarantee an increase in the average daily increment at harvesting by 3.6 ... 6.0 g with a reduction in the age of reaching the slaughter condition (3.0 kg of live weight) at 3.9 ... 6.3 days and feed costs per 1 kg of growth at 0.5 ... 0.6 k.o.

Thus, based on the conducted research, the feasibility of using the white-pennon and New Zealand white rabbits in regional cross-breeding systems was substantiated. It is expedient to introduce the best combination of rabbit breeds (1⁄2Kl1⁄2PnB × NzB and Cl × PnB, as well as 1⁄2KlNNBB×PnB and Cl × NzB) into the practice of commodity farms, which will allow additionally to obtain a surplus of products, which will significantly increase the economic efficiency of this industry.
