Effect of Dietary Supplementation of Chromium and Yeast on in vitro Dry Matter Degradability and Rumen Fermentation Pattern

Background: Yeast (Saccharomyces cerevisiae), widely used probiotics, was found to increase the utilization of fiber and improve production in ruminants. The concept chromium (Cr) supplementation has also received a great deal attention since past decade, as Cr could have supra-physiological benefits for domestic livestock. present vitro experiment conducted investigate effect dietary yeast on in-vitro dry matter degradability rumen fermentation by simulation technique. Methods: cerevisiae) (Y) (5 x 109 CFU /kg) (1.5 mg/kg) sorghum stover based complete diets (Basal diet: 10.58% CP) either alone or combination nutrient assessed Result: Chromium did not affect cumulative effective compared BD. enhanced (P less than 0.01) DM 12, 24 48 h, lowered ammonia nitrogen level comparison control. When control, positively affected pattern but no further improvement observed only diet.
