Perfil bioquímico de porcas no pré-parto e sua relação com o peso dos leitões ao nascimento

Abstract

In order to identify our biochemical components of pre-partum sows that are related to the reproductive traits, was collected blood of 16 (DB) matrices in a commercial pig farm located in the municipality of Monte Alegre de Minas, Minas Gerais . After obtaining the samples, separation of serum and plasma was proceed to determine the protein profile (total protein, albumin, globulins), enzymatic profile (AST, CK, GGT) and mineral (calcium, phosphorus, magnesium and Ca: P ratio), as well as the individual and average weight of the litter will be recorded. There was no significant correlations between biochemical components of the sows and the weight of piglets at birth. The mean values of albumin, globulin, albumin / globulin and total protein concentrations were similar to those of the albumin value, 21 days before delivery, above normal and also on the day of delivery. Globulin and total proteins were below average, normal, unofficial or protein profile did not influence the mean weight of the litter, except for a variable globulin that showed weak correlation (0.03) at 14 days before delivery. The mineral profile was maintained with few variations, and there was a difference not on the 14th day before delivery, where the calcium value was above the normal average and the phosphorus value below, thus altering the calcium / phosphorus ratio, which did not influence the weight of the litter. Magnesium presented a weak correlation (0.02) at 21 days. The enzymatic profile behaves heterogeneously, being a CK enzyme, simultaneously, however, there was also no correlation with the average weight of the litter. In view, it is concluded that the biochemical profile of sows in the pre-partum did not influence the weight of the piglets at birth.
