Comparative effectiveness of organic acid complexes in the cultivation of broiler chickens

Abstract

The paper presents the experimental results using organic acid complexes BiSAlTek, Ecacid and NeoTerm in the diet of broiler chickens of the Cobb 500 cross. The study was carried out in the conditions of the scientific poultry factory of Belgorod State University named after V.Ya. Gorin. There were 4 groups of 100 heads each: I-control, II, III and IV-experimental. As the main diet the chickens of all groups received mixed feed corresponding to the growing periods. In addition to the main diet, the chickens of groups II, III and IV in the periods from 1 to 10 days and from 34 to 38 days of life were given BiSAlTek, Ecacid and NeoTerm acidifiers at the rate of 2.5, 0.5 and 1.5 l/t of water, respectively. The use of additives contributed to a significant, relative to the control, increase in the body weight of chickens of groups II, III and IV by 7.7%; 6.8% and 8.6%, respectively, against the feed cost reduction per 1 kg of the body weight by 8.3%; 7.7% and 9.5%.

Dynamics of Serum Protein Content and Productivity of Chickens With Different Tonus of the Autonomic Nervous System

“…The authors (Taldykina & Semenyutin, 2021) in their research claim that the decrease in the albumin fraction of pro-teins may be associated with their use as a plastic material during the intensive growth of chickens. Instead, there are conflicting data that suggest that based on the detected increase in the ratio of albumin to globulins due to the former, we can indirectly talk about increased meat productivity, and globulins -increased egg production (Povoznikov & Pustovaya, 2013;Pushkarev et al, 2021).…”
