The dynamics of free amino acids in chicken thigh muscle in experimental eimeriosis

Abstract

The aim of research work was to leam the content of free amino acids in femoral muscle of local black rock chickens of Azerbaijan in the experimental infestation of chickens with the dose of 20,000 and 100,000 sporulated oocysts of Eimeria tenella per bird. The composition of 17 free amino acids in muscle of chickens has been studied. It was revealed that the total amount of amino acids of femoral muscle of chicks of the control group was 21.495 mmol/g, in the group with dose 20000 oocysts of E. tenella - 14.223 mmol/g at the 5th day of the invasion, at the 7th day -14.205 mmol/g, at the 10th day-18.335 mmol/g. Consequently, the essential amino acids arriving into the muscle tissue, and are not used, and as pathological metabolic products in a form of free amino acids accumulated in the muscular tissue.
