Levels of nitrogenous substances and amino acids in bodies of Ross 308 hybrid cocks and hens over the course of rearing

Original language description

Over the course of Ross 308 hybrid broiler chick cock and hen rearing, whole chicken bodies including feathers were monitored for changes in the levels of nitrogenous substances, essential amino acids (EAA) and non-essential amino acids (NEAA). At five-day intervals (days 1, 5, 9, 15, 20, 26, 30, 35 and 40 of rearing), randomly selected chickens were slaughtered after 24 hours of fasting. Over the course of rearing, N-substance levels ranged between 629.1 and 429.0 g/kg dry matter in hen bodies and between 616.0 and 477.3 g/kg dry matter in cock bodies. N-substance levels were statistically significantly different in the two genders on rearing days 35 and 40 (P LESS-THAN OR EQUAL TO 0.01). The levels of all amino acids (AA) in dry body matter of chickens up to 15 days of age dropped significantly in stages, while in the period from day 20 to day 40 some AA levels increased or reached the baseline.
