Introduction
As a first approximation, my research focused on the nutrition of camelids, later deriving towards the evaluation of the chemical and biochemical composition of Broiler chicken meat; the latter being of great socio-nutritional importance, since this meat is economically accessible for many sectors of the population. Later, I focused my studies on the nutrition of ruminants, because it is the main productive activity in large and isolated areas, where it would be difficult to maintain another type of production. Normally sheep production is maintained under grazing conditions on naturalized pastures or on different succession ecosystems. In this context, my vision of scientific work points towards an integral approach, which interrelates the effect of diet and race on grazing behaviors, the composition of fatty acids in animal products, the profile of metabolic and stress indicators oxidative, the levels and quality of antioxidants, contrasting all of the above, with the transcriptional response (RT-qPCR) and protein (Western blot) of enzymes and key proteins of lipid and carbohydrate metabolism, both at the muscle level and at the gland level mammary in muscle tissue with the purpose of reducing the high percentage of saturated fatty acids that intrinsically possesses the meat of sheep, and in the mammary gland as a tool that allows to relate the high mortality rates of lambs between birth and weaning, with changes physiological events that occur in this gland during the peripartum. More recently, I have oriented all these advances to try to link this comprehensive vision with metabolomic studies that determine the risk to humans that involves the handling of animal products, such as meat and milk.
