Abstract
This article presents the results of a study that examined the effect of Felucen P-2 feed supplement on the growth and development, blood parameters and quality of meat of black African ostriches. The experiment was conducted on two groups of ostriches: the first group received the main diet and the second group received Felucen P-2 added to the main diet. It was found that Felucen P-2 was an effective feed supplement which increased the rate of growth and development of young ostriches. For example, at the age of 90 days, ostriches of the first group had a live weight of 19.15 kg, and of the second group - 20.35 kg; at the age of 120 days, the birds of the first group had a live weight of 29.10 kg and of the second group - 32.05 kg; at the age of 150 days, the birds of the first group had a live weight of 40.35 kg and of the second group - 44.95 kg. In addition, from the age of 120 days, the significant live weight gain was observed. During this period, average daily gains were 332-453 g. The insignificant superiority of ostriches of the second group over the first one by the biological value and meat quality was determined. The ash content in ostriches of the second group was 1.1%, and in the first group it was 0.9%; the moisture content was 75.3 and 77.1, respectively; the protein content was 20.9% and 19.1%, respectively; and the fat content was 2.7% and 2.9%, respectively. In general, meat products had high quality and dietary indicators.
