Variasi produksi volatile fatty acids pada ransum ruminansia dengan kandungan NDF berbeda (variation in volatile fatty production of Ruminant diet varying in their NDF Levels)

Abstract

An In vitro trial was been conducted to study the variation in VFA production of ruminant diets composed of various agriculture industrial byproduct and indicated protein and TDN content of 18% and 70% respectively. NDF content of diet Rl, R2 and R3 varied from 51%, 53% and 55% respectively. The result indicated the difference of NDF in these range had no effect on proportion of acetate and propionate and acetate/propionate ratio, but butyrat proportion differed among treatments ( p < 0,05). However, methane and efficiency of hexose conversion to VFA not difference among diets. The result indicated that the difference in dietary NDF content of 5% had no significant effect on proporrtion of fermentation products.
