The addition of the antioxidant “Bisphenol-5” in the dietary feed of broiler chickens in the amount of 0.0002, 0.0004, 0.0008 and 0.0015 % of its weight contributed to the dietary nutrients digestibility enhancement, their absorbability and assimilation of nitrogen, calcium, phosphorus, which affected the increase in the intensity of animal growth. The effective dose application of the antioxidant under study in broiler raising is 0.0008 % of feed weight. Feeding of mixed fodders enriched with antioxidant at the given dosage of the third experimental bird group increased the digestibility of organic matter by 4.28 % (p ≤ 0.001), increased absorption of nitrogen, calcium, phosphorus by 1.07, 0.27, 0.2 g (p ≤ 0.001) respectively and increased average daily live weight by 13.6 % (p ≤ 0.001) compared with individuals in the control group. |
