In the conditions of the Republic of Belarus there were analyzed peculiar features of nutritive elements consumption (first of all, crude protein and nonreplaceable amino acids), as well as meaty qualities of swine of different genotypes bred in the Republic. Researches helped to determine pedigree differences in intake and usage on growth of separate nutrients of feeds (including crude protein and essential amino acids). Gilts of Duroc breed consumed per 1 unit of live weight at growing as from 30 to 80 kg, as well as up to 100 kg of live weight, correspondingly, 1,161 and 1,366 kg of raw protein. 0,066 and 0,077 kg of lysine including 0,051 and 0,060 kg of a digestible one. Animals of Belarusian meal breed consumed, correspondingly, 1,356 and 1,498 kg of crude protein, 0,079 and 0.085 kg of lysine, including 0,064 and 0,069 kg of accessible one. Nutrients spends for muscular tissue growth of Great white breed of pigs were the largest - 1,358 and 1,675 kg of crude protein, 0,077 and 0,095 kg of lysine, including 0,062 and 0,076 kg of accessible one. So the higher meatiness of animals is the less essential amino acids (first of all lysine) animals use for muscle weight synthesis.
