Abstract

The cultivation of young pigs is the most important stage in pig farming, the results of which depend on the final zootechnical and economic indicators of the industry. Therefore, attention should be paid to raising the young, especially early prediction of its viability and productivity. In this connection, in order to ensure cost-effective production of pork, one of the main components in the technology of raising young pigs is the study of postnatal ethological reactions of piglets to ensure their future performance and safety.In connection with the above, we consider that the relevance of this problem is to study postnatal ethological parameters of pigs, which in the future affects their viability, preservation and growth and, as a consequence, increases the profitability of pork production.The purpose of the research was to study the ethological characteristics of newborn piglets in the genotype. Studies on ethological indicators of piglets were held in a pig farms Mykolayiv andKhersonregions. To realize this goal, we investigated the behavior by visual observations with the subsequent calculation of the material obtained. The main criteria for ethological research were indicators of the time of implementation of the act “standing” after birth, the first contact with the mother’s maternity and the first act of “colostrum” sucking. Productive qualities of suckling pigs were evaluated according to the generally accepted indicators in pig production.Based on our observations and calculations, we found that crossbred piglets, derived from the maternal form of the large white breed and the father's breed of landraces for the implementation of the posture “standing” after birth, the first contact with the mother’s uterus and the act of sucking colostrum, consumed less time ‒ 2,53 min., 4,7 min. and 8,1 min. respectively, in comparison with their peers of the studied genotypes. This fact, in turn, contributed to an increase in the productivity of suckling piglets.So, we note that the analysis of the ethological parameters of piglets after birth indicates that the implementation of the act of “standing” of a pig after birth can serve as an indicator of its viability, since piglets that quickly rise to limbs spend less time on the act of “standing” after birth, respectively, earlier find and capture the nipples of the sows, which results in the timely receipt of colostrum, further reflected in their growth and preservation.In addition, attention is also drawn to the tendency for farmers to take into account that the increase in the live weight of newborn piglets leads not only to the many born piglets (as is well known) but also to an increase in the time of search-indicative reflexes in newborn piglets, which in turn, reduces the viability, safety and productive significance of young pigs in the future.Next, we should note that our research is intended to pay special attention to the worker-operators for the maintenance of the farrowing district. It was investigated the fact that during the reception of a farrow, the piglets immediately born (after the primary processing) to allow the sows to swaddle for the rapid implementation of the ethological parameters of the newborn piglets will further ensure the better viability and productivity of the obtained young pigs.
