AMINO ACID COMPOSITION AND BIOLOGICAL VALUE OF PROTEINS IN THE MEAT OF DIFFERENT-GENOTYPE PIGS
Abstract
It was established that the meat of young of Belarusian black-motley breed has the highest content of threonine, leucine, and arginine and all other essential amino acids has no significant drawbacks. For the tryptophan, isoleucine, methionine, valine, phenylalanine and histidine content, the Yorkshire breed animals have an advantage, but they are significantly limited (SCOR – 71.7 %) for the leucine content, indicating the imbalance of amino acid composition. Landrace animals have a small amount of methionine (SCOR – 94.4 %), the Belarusian large white – threonine (SCOR – 94.5 %). Belarusian meat breed and Duroc have a balanced amino acid composition. The protein quality indicator is set in the range 7.5–9.6.
