Abstract:

This study was conducted to evaluate dietary supplementation of Aloe saponaria (AS) on rumen fermentation and rumen microbial diversity in in vitro. Two different forms of AS (heat dried [HAS] and freeze dried [FAS]) were prepared and five treatments were used for in vitro fermentation over a 48-h incubation period: no addition of AS (CON), 1% and 2% addition of HAS (HAS1, HAS2, respectively), and the same level of FAS addition (FAS1, FAS2 respectively). Significantly higher (P < 0.05) gas production was observed in AS treatments than CON during the incubation. The addition, levels, and drying methods of the AS did not affect (P > 0.05) the production of methane and gas fitted parameters. The in vitro nutrient degradability, pH and ammonia-N concentrations of AS treatments did not differ (P > 0.05) from CON. AS addition and levels significantly increased (P < 0.05) the total VFA, acetate proportion, general bacteria, fungi, and methanogenic archaea but the freeze dried AS decreased ciliate protozoa (P < 0.05) abundance. In conclusion, freeze dried AS can reduce rumen ciliate protozoa and safely manipulate the ruminant fermentation characteristics.
