N. ². Petrovskiy, ². O. Golovatyuk
On the basis of researches the feasibility of using producing boars of Landrace breed was established, evaluated by fattening performance landed of cross-breed piglets, recommendations on the production of growing animals and their rational use were prepared. Use in cross breed Landrace boars of Large White sows fattening makes it possible to raise the quality of seed at 9,5 %, to reduce feed costs for 1 kg of growth within 0,76 feeding units. This form of combination of parental forms has the most positive impact on fattening qualities of pigs. Hybridization is a method of effective use of compulsory features of pigs and their genetic mobilization of reserves, to improve an important technological elements pork production - fattening qualities. Thus, received higher quality in fattening farms in the local young animals. Cost-effectiveness of implementation while fattening per 100 head per year - 3947 grn.
