Abstract

Heat stress had adverse effects on rumen fermentation and growth performance of goats. This study was to evaluate the effects of Saccharomyces cerevisiae (SC), Clostridium butyricum (CB) and their combination on rumen fermentation and growth performance of heat-stressed goats. Probiotics treatment were control (with no probiotics), 0.60%SC, 0.05%CB, and 0.60%SC + 0.05%CB (CG, SC, CB, and COM), respectively. Heat-stressed goats (n = 12, 20.21 ± 2.30 kg) were assigned to a 4 × 3 incomplete Latin square study. The dry matter intake (DMI) and body weight of goats were recorded daily. And the rumen contents and feces were collected for fermentation parameters and feed digestibility analysis, respectively. The rumen pH; rumen cellulolytic enzyme (avicelase, CMCaes, cellobiase, and xylanase) activities; the concentrations of rumen total volatile fatty acid, acetic acid, propionic acid, and acetic acid to propionic acid ratio; the DMI, average daily gain (ADG), and the digestibility of dry matter (DM), neutral detergent fiber (NDF), and acidic detergent fibe (ADF) were significantly increased (p < 0.05); while the rumen oxidation-reduction potential (ORP) was significantly decreased with SC, CB and their combination supplementation (p < 0.05) compared with that of CG. These results indicated that the supplementation with these probiotics were beneficial for rumen fermentation and growth performance of heat-stressed goats.
