METHOD FOR DETECTING YOUNG BULLS AT HIGH POTENTIAL OF MEAT PERFORMANCE Russian patent published in 2007 - IPC A01K67/02 G01N33/493 

FIELD: animal science.

SUBSTANCE: the present innovation deals with daily collection of urine followed by detecting there the concentration of creatinine and 3-methylhistidine. According to the data of urinary secretion of creatinine of 3-methylhistidine one should determine the rate of deposition and degradation of proteins in skeletal muscles, moreover, the evaluation of the results obtained should be carried out according to relative degradation of muscular proteins (RDP) estimated by the following formula: RDP,%/d=100xrate of degradation/rate of protein deposition, g/d. Young bulls at RDP value being about 1.51-2.05%/d should be referred to animals of low potential of meat performance, and at values ranged 1.10-1.50%/d - to animals of high potential of meat performance. The innovation enables to predict meat qualities of stud bulls before obtaining the offspring and accelerate selection process.

EFFECT: higher accuracy and efficiency of detection.
