The use of kume grass (Sorghum plumosum var. Timorense) bioconverted with white-rot fungi (Pleurotus ostreatus) fed on local goat in East Nusa Tenggara

Abstract

This experiment was undertaken for three months to study the use of kume grass
(Sorghum plumosum var. Timorense) bioconverted with white-rot fungi (Pleurotus ostreatus) fed on local goat due to the increased perception that antibiotics and chemical compounds should not be routineously used as feed additives. The experiment used twenty four local goat of 1 – 1.5 years old with an initial body weight ranging from 11.65 to 16.49 kg and coefficient of variation 10.31 %. Experimental design used was completely randomized design consisted of three treatments and five replications. The treatments were T0 = 100% basal feed; T1 = 84% basal feed + 16% kume grass;and T2 = 84% basal feed + 16% bioconverted kume grass. The variables measured were nutrients (dry matter, organic matter, crude fat, crude fiber, and nitrogen free extract) intake. The results of the research indicated that nutrients intake (dry matter, organic matter, crude fat, crude fiber, and nitrogen free extract) of T1 was significant (P< 0.05) better than the other two treatments except crude protein. Meanwhile, nutrients digestibility (dry matter, organic matter, crude fat, crude fiber, and nitrogen free extract) of T2 was significant (P< 0.05) better than the other two treatments except nitrogen free extract, and for body weight gain as well, T2 was significant (P< 0.05) better than the other two treatments. It is concluded that kume grass bioconverted with white-rot fungi increased nutrients digestibility of the diet and positively affected the growth of local goat, and in turn increased body
weight gain.
