Abstract

Experiments were carried out on 15-day chicks of 160 heads belonging to the Ross-308 cross. For the experiment, 4 groups were formed. Group 1 chicks were a control group and fed mixed feed, which was used in the farm until the end of the experiment. Group 2-3-4 experimental group chicks were given different amounts of chitosan hydroxyapatite (grower) with food ration for 13 days from the 15th to the 28th. Including: experimental group 2 chicks were given 0.4 g/kg, Experimental Group 3 chicks were given 0.7 g/kg and Experimental Group 4 chicks were given 1g/kg. At the end of the experiment, the best results were observed in the chicks of the third experimental group. In the control group in particular, the body temperature from the clinical-physiological indicators turned out to be 2.4% higher than in Group 3. And the number of breaths increased by 6.2% compared to control. Body weight was 8.3% higher. Sustainability was 100% in the 3rd experimental group at the end of the experiment and 92.5% in the control group.
