摘要：Banana by-products viz., stem, pseudostem and leaves were evaluated in three sequential runs measured at 8, 12, 24, 48 and 72 h using Hoheneim gas production test on rumen fermentation pattern. The exponential equation of gas produced by Stem is Y = -6.68+56.71 (1-EXP(-0.0153 t-l)) Lag time: 8.2 h, RSD1.09, pseudostem is Y = -11.14+69.27 (1-EXP(-0.0209 t-l}) Lag time: 8.4 h, RSD1.86 and leaves is Y = -3.79+44.58 (1-EXP{-0.0259 t-l}) Lag time 3.4 h, RSD1.40. The acetate propionate ratio was observed to be relatively higher in leaves than stem and pseudostem. The apparent and true dry matter degradability of the stem was significantly (p<0.05) lower than pseudostem and leaves. Pseudostem and leaves were able to generate microbial production at significantly (p<0.05) higher level than stem at 24 and 36 h of incubation, while stem could support significantly (p<0.05) better than pseudostem and leaves later than 48 h of incubation. Inverse relationship existed between YATP and incubation period. Pseudostem had the lowest partition factor compared to stem and leaves. The values range from 2.24 to 4.99. The half time (T½) was 45.46 h for stem, 33.03 h for pseudostem and 26.8 h for leaves. The microbial biomass production, energetic efficiency of Volatile fatty acid s and YATP was significantly (p<0.05) highest in leaves when compared to stem and pseudostem at T½ of c. Hence among by-products evaluated for their fodder potential to cattle, banana leaves rank first with low partition factor, high YATP and high microbial biomass followed by pseudostem and banana stem.
