Metabolic profile of santa inês ewes whith low body condition score during peripartum
Abstract
The objective of this study was to analyse the variations in the metabolic profile of protein, energy enzyme and mineral of Santa Inês ewes with low body condition score (BCS) during peripartum. Blood samples were collected from 12 animals by jugular venipuncture to determine the serum biochemical profiles of protein, energy, mineral and enzyme metabolisms. Samples were collected on the following days: days 28, 21, 14, and 7 before lambing, at birth and, at days 2, 4, 7, 14, 21, and 28 postpartum (dpp). The samples were centrifuged and the serum analysed by Automated-Analyser. There was no alteration of the BCS during the 28 dpp, between 0.6 and 2.1 ± 2.4 ± 0.5, and was considered, as lean. The values of the total serum protein, globulin, albumin, and albumin/globulin ratio were reduced effective from the period before birth until 28dpp. The values of beta-hydroxybutyrate, calcium, phosphorus and magnesium remained below those of reference values. The concentrations of alanin aminotransferase (ALT) were decreased particularly during the weeks before delivery. It was concluded that Santa Inês sheep with low body condition score demonstrated a reduction in the metabolism of proteins, energy, mineral and enzyme during peripartum.
