Abstract

The objective of this study was to characterize the serum concentration of macrominerals of Blackbelly sheep under free grazing conditions in Ecuadorian Amazon. Twenty-two Blackbelly sheep, belonging to the Centro de Investigación, Posgrado y Conservación de la Biodiversidad Amazónica (CIPCA) and raised under the same environmental, nutritional and managerial conditions, were studied during the summer period April-June. Blood samples were taken from the coccygeal vein 30 days before lambing, at lambing time and at 30 and 60 days after lambing. Mg2+, Na and P variables showed no significant differences (P>=0.05) with time. However, Ca2+ showed significant differences (P>=0.05), with changes at lambing time and 30 days after. In conclusion, there is a serum deficit of Ca2+ and P in the studied population of Blackbelly sheep under free grazing conditions of Ecuadorian Amazonia during all the period. Supplementation should be selective for these minerals.
Key words: nutrition, sheep, postparturition, blood serum
