MORPHOLOGICAL AND BIOCHEMICAL PARAMETERS OF OSTRICH FEMALES BLOOD IN THE OVIPOSITION PERIOD UNDER DIFFERENT LEVELS OF Lysine IN COMPOUND FEED
Current state of ostrich production in Ukraine requires profound research in metabolic status of the bird body under different feeding levels. It has been experimentally found out that the content of lysine in animal feed composition influences hemoglobin concentration in female ostriches during the oviposition. Hemoglobin level was 133.1 g/l in the control group birds. It has been found out that using 1,1% of lysine in animal feed results in hemoglobin increase in the blood of the research group birds. The difference from the control was 7.7% (r≤0,01). Using feed containing 1,1% of lysine increases protein anabolism in female ostriches during oviposition, which is confirmedly the trend aspartate aminotransferase, alanine aminotransferase, total protein rising activity and decrease in the concentration of uric acid in the blood serum.
