Biological preparation in prevention of the transport stress of the imported heifers

Abstract

Regularities of selective mobilization simpato-adrenal, seroto-nin - and gistaminergic the systems of an organism, morphological and bio-chemical profiles of blood, activity of enzymes of reamination and factors of a nonspecific rezistenost against the background of application of the biological products directed to prevention of a transport stress and realization of biore-source potential of the imported heifers to pressure ecological and technological a stress factors are disclosed. The intramuscular injection the transported animal of the medicines PS-7 and Prevention-N-S reduced concentration of catechola-mines in components of blood of animal 1st and 2nd skilled groups by 7,2-16,5% and 10,9-19,1% and a histamine for 1,3-4,3% and 2,6-4,1% in compari-son with control and, on the contrary, increased concentration of serotonin for 2,2-4,1% and 2,6-5,5% (Р<0,01-0,001). Against the background of application of biological products improvement of reproductive qualities of heifers of the 1st and 2nd skilled groups is established, the age of fruitful insemination for 1,35 and 1,53 months, age of the first childbirths - for 1,0 and 1,2 months, the index of insemination - in 1,42 and 1,93 times, service period - was reduced by 8,8 and 12,2 days and the breeding effeciency in 1 hunting in 1,7 and 2,0 times ( Р <0,05-0,01), than in control raised.
