Meat Traits, Physical and Chemical Values and Chemical Content of Meat and Fat of Landrace Breed of Pigs of Canadian Selection and Its Crosses with Belarusian Meat Breed
Researches were conducted in 2009 on pedigree farm «Zadneprovsky» in Vitebsk region on Landrace breed of animals of Canadian selection and its crosses with Belarusian meat breed. It was determined that animals of Landrace breed surpassed 2-breed coevals BMхL on meat performance traits. So backfat thickness above the 6-7th dorsal vertebra made 16,5 mm, the rear third part of half-carcass weight - 10,6 kg, loin area - 48,6 cm2. Purebred animals gave way on the carcass length to crosses at 2,2 % (P≤0,05). The meat of young animals of all the genotypes tested was of a good quality, PSE or DFD signs were not determined, pH in 24 hours after slaughter made 5,6 acidity units. Analysis of chemical content of the longest back muscle didn’t show variability on moisture, fat, ash and protein content.
