Growth muscel dinamics of chickens of cross “Sheiver 2000”

Abstract


The growth muscles dynamics of males and females chickens of 1-, 28-, 42-, 140-, 210-, 320- and 476-days of age of cross “Shaver 2000”. It was found that the most intense muscle growth occurs up to 42 days of age. The total weight of the carcass muscle in postembryonic period increased in males at 96,82 times, in females - 71,91 times. Muscle growth of anatomical areas is uneven, the absolute mass of the axial skeleton in 476-day-old males increased in comparison with the mass of 1-day-old at 120,40 times, chickens (females) - at 101,36 times; peripheral at 83,38 and 60,16 times; wings - at 86,99 and 64,97 times, pelvic limb - at 81,47 and 57,78 times, respectively. With age and the increase of the carcass muscle in the total weight mass relative axial skeletal muscles of males increased from 31,81% (1-day-old) to 40,30% (476-day-old), chicken (females) - from 28,47% to 40,19%; peripheral (males) decreased from 68,19% to 59,70%, females - from 71,53% to 59,81%.
