Bulls, Metabolic profileAbstract
Bulls are an important category in cattle production systems, being responsible for a considerable part of genetic improvement in a herd. However, few studies about the metabolic conditions of this category have been done. The objective of this study was to evaluate the metabolic profile of bulls in three different phases of the reproductive cycle, that are, before, during and after the breeding season. This study was conducted with 23 bulls, in a farm in southern Rio Grande do Sul. The biochemical markers used for the evaluations were: glicose and cholesterol, to determine energetic profile; albumin and urea to determine protein profile and enzyme aspartate aminotransferase (AST) as an indicator of liver functionality. There was a difference (p < 0,05) in all metabolic markers evaluated during the different phases of the productive cycle, showing that there was a variation in food availability, which could lead to productive and reproductive losses. This could be improved by protein supplementation and pasture improvement.Downloads
