    Introduction: Production systems for goats in Colombia have had an important development in recent years, increasing production levels by the use of animals with a higher genetic merit, which demands a better nutritional management of folds. Materials and methods: Fifteen Saanen and alpine goats were evaluated during three periods of a 90 days lactation: P1: 10 days after birth; P2: 60 days after birth and P3: 90 days after birth, aiming to determine the plasmatic concentrations of the main metabolites that indicate the energetic and protein metabolism of animals fed with several silage types. With that objective, goats were assigned randomly in three corrals in which they were fed different silage types (corn, sorghum and sunflower). Results and discussion: The indicators of the energetic metabolism had, in al of the diets, an increase in their concentrations as lactation progressed, except the glucose, which kept constant concentrations during the three periods. The same happened to albumin, BUN and ALT concentrations. Conclusions: Lactation stage is very important to determine the concentrations of the metabolites that indicate energy, due to the increase of the production levels by the animals and the mobilization of body reserves. It is necessary to increase these studies, anyway, to know the effect of diets and the fold production stage in our country.
