- Abstract
Seasonal behaviour of some biochemical indicators from goats of North-eastern Argentina during two consecutive years, are presented. Nutritional deficiencies are commonly subclinic, they affect some productive indexes, and can only be detected through laboratory analysis. The determination and interpretation of certain biochemical parameters allow to asses the metabolic state of the animal, being this a valuable tool for the diagnosis of the rodeo. Goat production for this region is familiar and extensive; food is based almost exclusively on natural grass, shrubs and low vegetation. There is great seasonal variability that affects the quality and quantity of forage supply, and that depends of the performance of the rainfall regime. The work was carried out in the Province of Corrientes (Argentina). Sampling was carried out in each season on a total of 150 animals from different categories, for two years with very different rain records: 950 mm (2008) and 1,490 mm (2009). Blood parameters of energetic-nitrogen profile were determined by molecular absorption spectrophotometric techniques. All the parameters of the lipid profile were increased during summer of the rainy year. Total and HDL cholesterol were higher during the driest spring, and HDL cholesterol during the rainy winter. LDL cholesterol was increased during the winter of the first year and autumn of the second one. During winter and spring of the driest year, animals had hypoproteinemia and hypoalbuminemia. Low values of glycemia were detected during the driest autumn and winter and in summer of both years. It can be concluded that seasonal variations in some indicators of the energetic-protein profile were caused by changes in grass composition attributable to the pluviometric differences in both years.
