The effect of “Butamax 200” and “Propranolol” on the productivity of broiler chickens

Relevance. Contemporary poultry farming practices, often involving high stocking densities, can significantly alter the environmental conditions and dietary regimens experienced by chickens. These changes can have detrimental effects on the neurological and cardiovascular health of broiler chickens, ultimately impacting their meat yield. In response to these challenges, poultry producers are increasingly turning to pharmaceutical interventions. These medications aim to regulate cardiovascular function and metabolism, promote bone regeneration, and mitigate stress in birds. The purpose of the work is to assess the effect of “Butamax 200” and “Propranolol” on the productive qualities of broiler chickens. Results. The dynamics of live weight and growth rates during the rearing of broiler chickens indicate the effectiveness of the use of “Butaphosphane 200” and “Propranolol” preparations. The experimental groups differed in lower feed conversion compared to the control group by 23.11% and 28.3%, respectively. The efficiency index of broiler chicken rearing was significantly higher in the experimental groups. The EIPB of the 1st experimental group was 316 units, and the 2nd experimental group was 352 units, which exceeded the values of the control analogues by 114 and 150 units, respectively.
