The dynamics of immunoglobulins in pregnant sows during lactation under the action of organic selenium (Sel-Plex).

Abstract

The research was conducted on 10 pregnant sows (10-14 days antipartum), divided into two similar groups. In experimental group of sows 10-14 days antipartum and over the course of 45 days postpartum in the composition of the ration was administered (through a mixture at the feed block) the product Sel-Plex in the proportion of 1 kg / ton (100 g at 100 kg feed). The control group, 5 sows, were fed with the same feed, except for the product Sel-Plex. Sows in both groups received daily mixed fodder in two portions to an animal. Blood samples were taken 7 days antipartum, 12-14 and 40-42 days postpartum. The results obtained allow us to mention that the product Sel-Plex during the study (over 55 days) caused no adverse deviations in growing of pigs maintained under these sows. The biochemical investigations performed in pregnant sows by 7-10 days antipartum both groups showed that animals initially had a rather high immunological status. The IgA concentration constituted 71.2 mg/dl in the experimental group and 71.4 mg/dl in the control group.
