Huk M. Adaptive ability of young pigs of domestic and foreign selection in the conditions of industrial technology

When determining the live weight of gilts at 4 and 6 months of age, it was determined that the first experimental group had higher rates than the control group by 3.5 (p<0.05) and 4.5 kg (p<0.01). At the age of reaching a live weight of 100 kg, the pigs of the first experimental group prevailed over the analogues of the control group for 5 days (p<0.05). It was established by DNA stress test that the second experimental WB+(M×1/8P) group has 3% carriers of the mutant T allele, which is responsible for the stress gene RYR-1, which can occur in pigs in a homozygous state. During the control slaughter of pigs it has been determined that the second experimental group LW+(M×1/8P) outperformed the control (LW×LW) and the first (LW×M) experimental groups by pre-slaughter live weight by 4.8% and 10.8%, respectively.
