The use of kume grass (Sorghum Plumosum var. Timorense) to substitute king grass (Pennisetum purpurephoides) fed on Bali cattle in East Nusa Tenggara

Abstract

A research has been conducted for three months to study the use of kume standing hay
(Sorghum plumosum var. Timorense) hydrolyzed with natural alkali as Bali cattle feed. Twenty heads of Bali cattle of 1.0-1.5 years old (live body-weight of 119.20-158.40 kg). Experimental design used was completely randomized design consisted of five treatments and four replications. The treatments were : T0 = 80% king grass + 20% concentrate; T1 = 70% king grass + 20% concentrate + 10% hydrolyzed kume standing hay; T2 = 60% of king grass + 20% of concentrate + 20% hydrolyzed kume standing hay; T3 = 50% of king grass + 20% of concentrate + 30% hydrolyzed Kume standing hay; T4 = 40% of king grass + 20% of concentrate + 40% hydrolyzed kume standing hay. These treatments added with feed additive of 100g bioport and 100g bioplus probiotic. Analysis of variance was used to analyze data and Duncan’s multiple range test was used for further test. Variables measured were dry matter, organic matter, crude protein, crude fat, and crude fiber intake, and daily live weight gain. The results showed that content of dry matter, organic matter, crude fiber (P<0.05) decreased, while crude protein, crude fat, nitrogen free extract, and ADF were significant (P<0.05) increased. It can be concluded that kume standing hay hydrolyzed with natural alkali has a possibility to substitute king grass up to 30% in the ration of Bali cattle; and additives of bioplus and bioport probiotic each at level of 100 g was able to increase the intake of dry matter, organic matter, crude protein and crude fiber
and growth of Bali cattle.
