SUMMARY:

This work aimed to evaluate the metabolic response on the characteristics in the energetic, enzymatic, protein, mineral and hormonal profiles of buffalo heifers that received a diet with different levels of urea and sugarcane yeast. The experiment was carried out in the Buffalo Culture Sector of the Animal Science Department of the Federal Rural University of Pernambuco (DZ-UFRPE), with 20 Murrah heifers, individually confined and randomly distributed in four treatments, with five replications each. In the first design, Aa experimental diets were isoproteic, consisting of the use of sugarcane stalk (Saccharum officinarum L.) plus urea in linear proportion at concentrations of 0.0, 0.7, 1.4 and 2.1% with the roughage; in the second experiment, the focus of the experimental diet was on the concentrate with the replacement of percentage of soybean meal by sugarcane yeast and urea (0.0, 33.0, 67.0 and 100.0%). Blood was collected by jugular venipuncture in tubes with and without anticoagulant, for later obtaining serum and plasma, respectively, and processing the analyses. The results of the experiment with urea made it possible to verify that the variation in urea levels in the buffalo diet influenced the final weight gain, with a negative linear effect. As for the biochemical parameters, there was an influence on the plasma glucose concentration, on the serum concentration of urea and BUN, on the enzymatic activity of serum FA and on the urinary concentration of urea. Serum concentrations of macrominerals were not influenced by the variation of urea concentrations in the diet. In the second experiment, the replacement of soybean meal by sugarcane yeast influenced performance and metabolic dynamics, with total weight gain and average daily consumption with a quadratic effect. As for the biochemical profile, there was an influence on the serum concentration of triglycerides, on the serum activities of AST, GGT and alkaline phosphatase, in addition to the serum concentration of phosphorus and potassium, which showed positive linear effects. Regarding the essential metals, the elements Cu, Fe and Zn were possible to be quantified at all levels of sugarcane yeast in the diets offered. The use of urea and sugarcane yeast influence performance parameters and blood and urinary metabolic dynamics of Murrah buffalo heifers, so that the percentages of these dietary components should be offered based on clinical recommendations, so as not to cause loss weight and metabolic diseases.
