Influence of neurotropic drugs of metabolic action on embryonic growth of pigs and exit of pigs at birth
Abstract
Intensification of the pig industry should provide for the maximum use of biological characteristics of pigs not only through the provision of advanced methods of breeding and feeding, but also through the use of new biotechnological methods to stimulate the reproductive capacity of animals. The experiments were conducted at the agricultural complex "SWAT Kalita" village. Kalita, Brovary district, Kyiv region on sows of the breed large white. In each of these experiments, 3 groups of large white sows of 30 heads were formed after the first and second farrowing. Sows of the 1st and 2nd experimental groups were treated with biologically active drugs for 1-3 days of the sexual cycle at a dose of 20 ml; Group I - 18% "Glutam 1M" (total dose 10.8 g), II - "Stimulin-Vet". Animals in the control groups were fed 20 ml of saline. The drug was fed in the morning while feeding the animals. Sows were fed twice a day: 9.00-9.30 in the morning and 15.00-15.30 in the evening. The animal is provided with a full-fledged compound feed of its own production according to a special recipe SK-6. Sows in sexual hunting were selected twice a day using a test boar. Selected sows were placed in individual machines and inseminated with artificially pre-diluted semen twice with an interval of 18 hours. Before artificial insemination, sows were kept in group machines for 15 goals. It was found that feeding sows in the physiologically intense period of the sexual cycle of metabolic-neurotropic drugs "Glutam 1M" and "Stimulin Vet" 1-3 days of the sftate cycle had a positive effect on the growth rate of animals, mainly by increasing the number of newborn piglets and contributed increase in the number of business piglets, as well as probably their greater weight, with a class of 1.51 and more kg.
