ABSTRACT

The dynamics of biochemical parameters of the blood of broiler chickens that received various dosages of the extract of thyme, Thymus serpyllum L. have been studied. It has been established that the introduction of thyme extract into the diet of broiler chickens in the dosages of 2, 4, 6, 8 and 10 mg/kg of the body weight did not result in any significant changes of the studied indicators of the biochemical status of the blood of the experimental chickens. All indicators ranged within their physiological norms. A fairly pronounced tendency of increasing the content of total protein in the blood serum of the chickens in the experimental groups one through five was observed, compared to the reference : at the age of 21 days, from 6.9 to 21.8%; and at the age of 40 days, from 2.9 to 14.2%. The level of triglycerides in the blood serum of the chickens in the experimental groups was lower than that in the reference group : on day 21, from 23.0 to 36.3% and on day 40, from 1.7 to 51.3%.
Key words : Broiler chickens, extract, thyme, blood biochemical indicators
