ROA-VEGA, María Ligia; LADINO-ROMERO, Edgar Augusto  and  HERNANDEZ-MARTINEZ, María Cristina. Blood biochemistry indicators in cattle supplemented with Cratylia argentea and Saccharomyces cerevisiae . Pastos y Forrajes [online]. 2017, vol.40, n.2, pp. 144-151. ISSN 2078-8452.

The objective of this study was to evaluate some indicators of blood biochemistry in fistulated cattle, supplemented with Cratylia argentea and Saccharomyces cerevisiae grazing Brachiaria decumbens cv. Basilisk.Four bulls fistulated in rumen were used (Creole x Zebu), distributed in a Latin square (4 x 4). The treatments were: T1: grazing without probiotic (NP), T2: grazing with probiotic (WP), T3: grazing supplemented with 3,5 kg of dry matter (DM) of C. argentea (NP), and T4: grazing supplemented with 3,5 kg DM of C. argentea (WP). The crude protein content of C. argentea was 2,6 times higher than that of B. decumbens (18,2 vs. 6,5 %). With regards to the values of creatinine (Cr), alanine aminotransferase (ALT), albumin and globulins, a similar performance was observed in all the treatments; while blood ureic nitrogen (BUN), glycemia, aspartate aminotransferase (AST), total protein, cholesterol and triglycerides increased (p< 0,05) due to the effect of the probiotic and of the supplementation with legume (T2, T3 and T4). A positive correlation was found for glycemia-triglycerides, glycemia-total protein, glycemia-cholesterol, albumin-cholesterol, triglycerides-protein, and a negative correlation for BUN-AST. It is concluded that the biochemical indicators were within the normal ranges for the species; nevertheless, total protein, glycemia, BUN, cholesterol and triglycerides were higher in the treatments to which S. cerevisiae and C. argentea were added.
