Influence of stress-protective agents on the body condition and egg production of poultry under acute immobilization and hyperthermic stress

The compound “ASP-34”, when administered to laying hens of the Dekalb White cross at the age of 430 days, has a stress-protective effect, as evidenced by a shorter period of weakness and a faster recovery of normal feed and water consumption after immobilization and hyperthermic stress. The effect of the compound “ASP-34” on the poultry body at a dose of 100 mg/kg improves egg production: an increase in the productivity index by 8.84% compared to the positive control group and by 3.38% to the group with the reference sample, and an increase in the egg production intensity by 7.2% compared to the positive control group and by 2.9% to the group with the reference sample. The shell thickness increased in the experimental group by 6.70% compared to the reference sample group and by 10.30% compared to the positive control group; the number of broken eggs decreased by 2.22% compared to the reference sample group and by 2.04% compared to the positive control group
