abstract = {This study was conducted to investigate the effects of chitosan
on ruminal fermentation, methane production and microbial populations in diets
with different Forage to Concentrate (F:C) ratios in vitro. A two factorial
in vitro experiment was designed with one factor as three F:C ratios
(80:20, 50:50 and 20:80) diets and the other as four levels of chitosan in rumen-buffer
fluid (0, 333, 667 and 1000 mg L-1). After 24 h incubation, the results
showed that chitosan significantly decreased In Vitro Dry Matter Disappearance
(IVDMD) (p<0.001), total gas production (p<0.001), methane production
(p<0.001) and Acetate:Propionate (A:P) (p = 0.001) and significantly increased
the rumen pH (p<0.001). Chitosan significantly increased the molar proportion
of propionate of rumen-buffer fluid in F:C ratios of 80:20 (p = 0.009) and 50:50
(p = 0.007). In F:C ratios of 20:80, chitosan significantly increased the ammonia-N
concentration (p = 0.013) and the molar proportion of butyrate (p<0.001)
and significantly decreased the molar proportion of acetate (p = 0.001). In
conclusion, chitosan affected the ruminal fermentation and reduced methane production
of rumen-buffer fluid in vitro.}
