Effect of Duroc breed and German Selection Landrace breed of boars on performance of crossbred young animals

Abstract

In the course of research on the studying of fattening and meat qualities of pure breed and crossbred piglets was found that the combination Y× D had the best performance of fattening pigs productivity, whose age at 100 kg and average daily gain were 173,4 days (P ≤ 0,001) and 730 g (P ≤ 0,05), at a cost of feed 3,40 f. u. (P ≤ 0,001), respectively. The best meat characteristics were noted gilts combinations Y × D and ( BM × Y) × D, the square "eye muscle" to - 24,5 and 40,0 % (P ≤ 0,001) higher than the Yorkshire breed pigs. The best indicator of the mass of the posterior third of a side characterized hybrids (BM × Y) × D and Y × D 12,0 kg, which is 5,3 % (P ≤ 0,05) higher than the corresponding figures of the control group. The highest content of meat in the carcass differed crossbred Y × D and (BM × Y) × D 65,6 and 69,7 %, which is 5,3 (P ≤ 0,05) and 9,4 % (P ≤ 0,001) higher than the Yorkshire breed pigs.
