Abstract

Four levels of live yeast (Saccharomyces cerevisiae) culture in the in vitro digestibility of a more concentrated forage based cattle diet were evaluated. Ruminal fluid of two fistulated bulls was used, as a bacterial inoculum. Two Ankom® incubators were used for in vitro digestibility, where F57 bags (Ankom Technology) containing the samples of experimental treatments were deposited. The treatments were; T1: control diet with more concentrated forage, T2: T1 plus 1 g of CL (Yeast Culture) kg-1 of feed, T3: T1 plus 2 g of CL kg-1 of feed and T4: T1 plus 3 g of CL kg-1 of food. The experiment was developed in the Laboratory of Nutrition Rumiology and Metabolism with a duration of 90 days. In vitro dry matter degradability (DIMS) showed no changes at 3, 12 and 72 h of ruminal incubation because of CL supplementation. However, although in a non-linear manner, this CL caused differences for the incubation periods of 0, 6, 24 and 48 hours. The DRIV of organic matter (DIMO) did not present a linear behavior because of the increasing addition of CL to the base diet. There were differences only in incubation times of 3, 24 and 48 hours, but not in the longest incubation time (72 h). CLs do not cause clear changes in the degradability of the diets studied.
