ABSTRACT
The objective of this study was to evaluate the effect of supplementation with mineral
soap, organic mineral and roasted soyabean on ration fermentability in the rumen of sheep.
Thirty two Garut Sheep (initial weight 22.38 ± 3.56 kg) were assigned into a randomized
complete block design with 8 treatments. Body weight was used as blocks (4 blocks). The
treatments were FO: basal diet + fish oil, CO: basal diet + corn oil, CaFO: basal diet +
calcium soap of fish oil, CaCO: basal diet + calcium soap of corn oil, ZnFO: basal diet +
zinc soap of fish oil, ZnCO: basal diet + zinc soap of corn oil, RSB: basal diet + roasted
soya bean, MM: basal diet + mineral mix (Zn, Cu, Cr, and Se-organic). The experimental
diets were offered for 8 weeks. The results showed that ammonia concentrations of sheep
fed CO, CaFO, CaCO, and MM were higher than those of sheep fed FO, ZnFO, ZnCO,
RSB diets (9.28 v 6.75 mM). Vollatile fatty acid production was not affected by treatments
(110.6 ± 7.69 mM). The levels of amonia and VFA in this experiment were suitable for
microbial growth. Rumen bacterial population of sheep fed FO was the lowest (P
