Abstrak

A study has been carried out in Gianyar-Bali, to optimize the use of rice straw for fattening Bali cattle feed
through ammoniation and biofermentation treatment with Starbio and Trichoderma virideae. The Randomized
Block Design used in this experiment consisted of four combinations and three blocks as replications with 1 unit
of experiment was 1 Bali bull. The first treatment is to use a ration consisting of rice straw without treatment given
ad libitum + complete feed 1.5% of the live weight of livestock. The second, third, and fourth treatments were the
same as ration control, but were also supplemented with urea ammoniation, biofermentation with starbio, and
Trichoderma virideae. The measured variables included using the ration, nutrient deposition, energy retention,
livestock weight gain and feed conversion ratio (FCR). The results showed that the consumption of dry matter
control ration was significantly higher (P <0.05). However, nutrient deposition, energy retention and weight gain
were higher in rice jeram based rations with urea ammonation treatment and biofermentation with starbio or with
Trichoderma virideae. Of the four treatments, it turns out that rice straw treated with urea ammonia gave the best
results with the highest live weight gain (0.53 vs 0.47, 0.46 and 0.41 kg/head/day). Based on the results of this
study it can be concluded that rice straw with urea ammoniation provides optimal utilization as the basic feed of
Bali fattening cattle.
