The influence of retention technology on the performance of suckling sows

The intensive production of pig production puts new demands on the technological features of the pig industry. In recent years, in industrial pig breeding, along with the general increase in production intensity, there have been exacerbation of a number of problems (decrease in preservation of young animals, increase in the number of emergency farrows, decrease in productivity of young animals, etc.). To overcome these negative trends, it is necessary to develop new intensive technological solutions to create optimal conditions of confinement at the pig complexes. In today's context, there are discussions about the type of sowing machine location in a farrowing box: diagonal or straight? But both the direct location of the cell and the diagonal have, according to research, their advantages and disadvantages. Therefore, the purpose of the study was to investigate the performance of suckling sows and mammals depending on the location of the locking machines in the farrowing box (diagonal or straight). The studies were conducted under the conditions of Agro Firm «MIG-Service-Agro» of the Novoodeskiy region, Mykolaiv Oblast, on the stock of purebred sows of the Landras breed and the uterus of the domestic breed pigs of the Durok breed of the Ukrainian selection «Stepoviye». In the farrowing shop two blocks of 8 boxes were taken for farrowing of sows with direct location of the locking machine – І and ІІ control groups and two blocks of farmering of 8 boxes for farrowing of sows with diagonal location of the locking machine – ІІІ and ІV experimental groups, and III and ІV experimental groups. Оther technological retention factors of the study groups were identical. The study of productive qualities of experimental animals was carried out according to generally accepted methodological recommendations. It is proved that the location of the sowing machine in the farrowing box affects the performance of their reproductive characteristics. The direct location of the locking machine for farrowing, unlike the diagonal one, caused an increase in the number of piglets when weaned - by 0.6 kg (P>0.95); retention rate - 5.1% (P>0.99); of the nest when weaned - by 25.0% (P>0.99). At the same time, no impact on the indicators of multiplicity, fertility and milk yield was established. The results obtained determine the prospects for further research.
