Study of the predominant types of the activity in sows under the on-farm conditions

A change in the external conditions leads to restructuring the adaptive behavior of animals, their motor activity, which makes it possible to use ethological properties to assess the body state in different production modes. In this regard, there is an urgent need for total monitoring of the health status and activity of pigs. The article contains the results on the effect of different-type stress on the pig stock during the rearing period under on-farm conditions. The studies were carried out at the pig farm of the State Enterprise “ZhodinoAgroPlemElita” in the groups of lactating sows kept under identical conditions, based on monitoring by year seasons in the following algorithm: complying with comfort criteria, reducing the stress impact, improving the health status, increasing the productivity. The predominant activity types of sows under on-farm conditions have been studied. It has been found that the predominance of the comfort activity among other types contributes to the offspring viability. Types of the activity of sows are inextricably linked to motivations, that is, the desire of animals to satisfy the priority needs of the body. Examples of high and low food motivation have been identified. Extra space, physical and visual barriers to protect more submissive sows have been found to have a positive effect on reducing overall aggression.
