Abstract

The aim of the research was to compare the productive qualities of the purebred and cross-breeding young pigs on the fattening of Canadian breeding in two- and three-breed crossings. Object of the study: youngsters of the Landras pigs, two-breed hybrids (Landras x Yorkshire), three-breeders (Landras x Yorkshire x Duroc), imported from Canada to the KFKH "Il'tyakov VN", Oftenozero district of the Kurgan region. The results of the experiment showed that under the same feeding conditions and the content of purebred, two- and three-breeded young pigs of Canadian breeding, differences in the character of the change in the dynamics of the live mass are observed. The gross increase in live weight was the highest in three-breed hybrids and amounted to 128.32 kg, which is 4.27% (P <0.05) higher than for pure-landrace. The age of reaching a live weight of 100 kg was the smallest in the three-breed hybrids in comparison with the two-breed hybrids and purebred landrace at 2.69 and 5.83 days. The slaughter yield in tri-tribe hybrids exceeded the purebred landrace by 1.25% (P <0.01). The weight of the paired carcass was also higher in tri-hybrids compared to the bipedal hybrids at 2.49 and purebred landrasas - by 7.36% (P <0.05). The highest content of dry matter was characterized by meat obtained from pure-earthland, while the protein and intramuscular fat content did not differ significantly and was within the range of 22.35-22.45% and 2.52-2.55%, respectively.
