Comparative characteristics of amino acid composition of meat of crossbred and purebred young stock rabbits

Abstract

The contents of the essential and nonessential amino acids in meat of the crossbred (White Giant × Soviet Chinchilla × Californian) and purebred (White Giant and Soviet Chinchilla) young stock rabbits are analyzed. The age-associated tendencies to both increasing and decreasing the essential amino acid contents have been ascertained in the crossbred rabbits and the purebred animals, respectively. The highest increase in the value for meat protein quality was registered in the crossbred young stock animals (20.7%) aged 77 to 90 days, while the lowest rise for the item was recorded in the White Giant peers (1.5%). The essential amino acid contents in the boneless carcasses of the crossbred young stock animals compared to the White Giant and the Soviet Chinchilla young-stock rabbits at the age of 77 days were 5.9 g or 6.5% and 9.3 g or 10.6% higher, respectively; with respect to the 90-day-old animals, the values comprised 9.9 g or 9.2% and 18.3 g or 18.5%, respectively.
