Meat-fat Traits and Morphological Content of Pig Carcass of Different Genotypes

Abstract

As a result of researches positive influence of boars of Yorkshire, Duroc and Landrace breeds of Canadian selection at meat-fat traits of the produced hybrids was determined. It is determined that tri-breed crosses (Great White Breed x Belarusian Meat Breed) x Landrace, (Belarusian Meat Breed x Landrace) x Duroc and (Belarusian eat Breed x Landrace) x Landrace surpassed their analogues of the control group: on carcass length - at 1,81 cm (P≤0,001), 1,14 cm (P≤0,001) and 2,69 cm (P≤0,001); on loin eye area - at 20,8 % (P≤0,001), 27,2 % (P≤0,001) and 37,4 % (P≤0,001); on ham weight - at 0,46 kg (P≤0,01), 0,97 kg (P≤0,001) and 0,69 kg (P≤0,01) correspondingly. Animals of genotype of (Belarusian eat Breed x Landrace) x Landrace had the smallest backfat thickness (17,22 mm), it was 28,3 % (P≤0,001) lower than that of the control group animals.
