SUMMARY:

Probiotics are food supplements based on live microorganisms capable of adjusting the balance of the intestinal microbiota and increasing the productive capacity of pigs. The effects of probiotic supplementation were evaluated over the colostrum quality for matrices in the final stage of gestation. In the experiment methodology, the probiotic was offered in the feeding of the matrices, for 40 days. Two matrices groups were formed: Control and Treatment. At the beginning of the farrowing, a blood sample was collected from the matrice swine and her piglets were weighed. After 24 hours the piglets were weighed again and a blood sample was collected from each piglet to determine the their immunoglobulins concentration using the immunocrit method. In the analysis, in relation to the matrices, there was no difference between the treatment group and the control group (P>0,05). However, there was effect on immunoglobulins levels of the farrowing order (P<0,05). For blood samples from piglets, comparing all piglets in the treatment and control group, there was no difference in the amount of Ig (P>0,05). However, analyzing separately the piglets groups that were born at the end of the farrowing, of these, the piglets from the probiotics supplemented matrices had a lower drop in the immunocrit rate compared to the control group (P<0,05). There was also a significant difference (P<0,05) in piglet weight gain in the first 24 hours of life and in the amount of immunoglobulins in the blood of piglets considering the matrice's birth amount and piglet's birth order. It can be concluded, that probiotics are able to improve immunoglobulins levels in the blood and promote greater weight gain in newborn piglets.
