ANTI-STRESS ACTIVITY AND EFFICACY OF PHARMACOLOGIC COMPLEX SPAO TO THE CHICKENS OF PARENT FLOCK

 The authors of the article developed anti-stress pharmacologic complex for poultry industry (SPAO). In the work the data of the study of its stress-relieving activity and efficiency during preventive technology stress treatment of parent flock chicken for meat production are represented. Studies were conducted in chicken during their transfer from breeding of rearing flocks department to the department of adult vaccination. It was proved that this processing method is accompanied by the launch of adaptive mechanisms of formation of the stress response. Use of SPAO-complex with water in a dose of 185 mg/kg of body weight, according to the scheme 2 days before transfer and vaccination, at the day of the procedure and every 2 days after transfer and vaccination had a great impact on the stress-relieving effect on chickens. This effect manifested at all stages of stress reaction development during short period of adaptation, the period of stress development and the phase of development of long-term adaptation. Pharmacologic stress prevention was brought three times to evaluate efficacy of SPAO-complex during parent flock chicken management: at the age of 120 days in the period of transfer and vaccination, at the age 260 days during vaccination and at the age of 290 days during the introduction of parent stock of young cocks. In comparison with the control group we had higher economic performance in the group where pharmacologic stress prevention was brought: livability is higher by 2.25 %, egg production is higher by 2.11 %, hatching rate is up by 4.11 % mainly due to the increase of fertile eggs by 4.30 %. Damage by the mortality of parent flock chicken was prevented due to use of SPAO-complex, and incremental product was got. Economic efficiency of 1 ruble of expenses was 13.83 rubles.
