Respons terhadap Suplementasi Sabun Mineral dan Mineral Organik serta Kacang Kedelai Sangrai pada Indikator Fermentabilitas Ransum dalam Rumen Domba
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 < 0.05). Rumen protozoa population of sheep
fed CO, CaFO, ZnFO, ZnCO, and MM were lower (P < 0.05) than those of sheep
fed FO, CaCO, and RSB. It is concluded that supplemention of Ca-soap, organic
minerals, and roasted soyabeans to sheep ration increased ration fermentability
in the rumen. Ammonia and VFA concentrations were suitable for rumen microbial
growth. Fat protection (Ca-soap) did not inhibit bacterial growth in the rumen.
