چکیده
For the first time, based on complex research, a zootechnical justification for the use of biostimulators PS-2 and PS-4 in the technology of calf raising in individual boxes and pavilions is given to activate the body's adaptogenesis to cold and implement the productive qualities of young stock during rearing and fattening in typical premises. Intramuscular injection of PS-2 (polysaccharide complex of yeast cells immobilized in an agar gel by adding a benzimidazole derivative) and PS-4 (similar to PS-2 plus antibiotic of the cephalosporin) to calves in a dose of 3 ml at 2-3 and 7-9 days of life stimulates their growth and development during the raising, rearing, and fattening periods, reduces the incidence of disease. By the end of the growing period, the animals of the 1^st and 2^nd experimental groups outnumbered their control peers by 7.2 and 8.2 kg, rearing - by 11.4 and 13.6 kg, fattening - by 13.8 and 16.8 kg, respectively (P<0.05-0.01). A similar pattern occurred in the nature of changes in exterior measurements and growth coefficient of animals of the compared groups. At the same time, in calves of the 1^st and 2^nd experimental groups, respiratory and digestive diseases were reduced by 2.0 and 4.0 times, the recovery time was decreased by 3.47 and 5.12 days, and the Mellenberg coefficient was reduced by 3.7 and 12.1 times, respectively, compared to the control (P<0.05). It was found that PS-2 and PS-4 increased the pre-slaughter weight of young stock by 14.6 and 18.0 kg, the weight of the hot carcass - by 12.8 and 15.8 kg, the slaughter weight - by 13.7 and 16.5 kg (P<0.05-0.01). The weight of half-carcasses of the young stock of the experimental groups compared to the control group was higher by 6.7 and 8.7 kg, the yield of meat – by 5.4 and 6.9 kg, of bones – by 0.6 and 1.0 kg (P<0.05-0.001). With an increase in the weight of half-carcasses of experimental animals, the specific weight of the meat increased, and the bones, on the contrary, decreased. If the yield of meat of the highest and first grades in animals of experimental groups grew on the background of intramuscular injection of biostimulators, increased: when using PS-2 – by 0.6 and 0.3 % (P<0.01), PS-4 – by 0.9 and 1.1% (P<0.01), the second grade, on the contrary, decreased by 0.9 and 2.0 % (P>0.05), respectively, compared to the control.
