摘要
The objective of this study was to evaluate the effects of wheat meal alone or combined with Streptococcus bovis on the fermentation and chemical composition of guinea grass silage. A completely randomised design was used in the following treatments: deionised water, untreated; fresh forage plus 100gkg(-1) of wheat meal; S. bovis JB1 plus 100gkg(-1) of wheat meal; and S. bovis HC5 plus 100gkg(-1) of wheat meal, with six replications. There were a higher number of enterobacteria, moulds and yeast populations in the untreated silage (P<.05) compared to treated silages. The association of S. bovis with wheat meal resulted in lower pH and concentration of NH3-N (P<.05) than silages untreated and treated only with wheat meal. The use of both S. bovis JB1 and HC5 combined with 100gkg(-1) wheat meal can also be a good alternative to farmers for improving the silage quality of guinea grass silage.
