    Rapid and extensive degradation of faba beans (Vicia faba) by ruminal microbes can result in substantial and undesirable N loss from the rumen. The purpose of this study was to test the hypothesis that offering faba beans as a supplement more than once a day to sheep receiving a combination of oaten chaff and lucerne chaff as a basal diet will increase microbial protein supply to the intestines. The experiment was conducted in a Latin square design (4 x 4) using four mature merino sheep. The treatments were: T0 = basal diet ad libitum + nil supplements, T1 = T0 + faba beans (FB) fed once daily, T2 = T0 + FB fed twice daily, T3 = T0 + FB fed 8 times daily. The basal diet was given once per day at 09:00 in the morning while FB were given at the rate of approximately 0.5% of live body weight and delivered according to the treatment protocol. Urinary excretion of purine derivative (PD) was used to estimate microbial protein supply. The results indicated that even though treatment statistically had no effects on total urine output, PD excretion in the urine, PD absorbed, estimated microbial N supply, and the efficiency of rumen microbial protein synthesis, provision of supplement to sheep numerically improved microbial N supply by 92% compared to that of control group. However, there were no differences within the supplemented group. Therefore, it is concluded that feeding faba beans more than once a day was unnecessary.

    This research was conducted to determine the resistance degree of lactic acid bacteria (LAB) isolated from the faeces of broilers towards various intestinal conditions, in order to select a lactic acid bacteria to be used as prospective probiotic. Ten types of LAB bacteria (M1, M2, M3, M4, M5, M7, M8, M23 ,M26, and M28) isolated from the faeces of broiler chicken were subjected to pH2, pH3, and pH4; to 3% bile salt and to the temperatures of 30oC, 37oC and 41oC. The results of the research showed that all LAB isolates experienced the highest colony reductions at pH2, which was around 3.2 - 5.5 log units/ml. The reduction of colony numbers at pH3 was approximately 1.8-3.1 log unit/ml, and the reduction at pH4 was around 1.0 ??? 2.5 log unit/ml. All the LAB isolates experienced a decrease of 0.5 log unit/ml to 1.6 log unit/ml in colony numbers after bile salt exposure. The reduction of colony numbers of ten LAB isolates at the temperatures of 30oC, 37oC and 41oC was 0.6 - 1.4 log unit/ml, 0.1 ??? 0.5 log unit/ml and 0.7 ??? 1.4 log unit/ml, respectively. None of the ten isolates posses all of the expected characteristic, however based on its more superior ability to block the pathogenic microorganism as well as its ability to survive in simulated gastro intestinal tract conditions, M1 was selected as prospective probiotic

    Integration of mulberry plant and livestock can be optimal when implement the applicable management that promote benefits to the farmers, so it can support its sustainability. The aim of this research was to improve farmers??? income as well as animal productivity by exploring some applicative models. There were three applicative models which were tested: the P1 Model= introduction of two goats into the silkworm farming system to enable them to utilize mulberry leaves that are not consumed by the silkworms; the P2 Model= Using the whole mulberry plants as feed ingredients for two feedlot cattle; the P3 Model= Selling mulberry leaves produced for concentrate ingredient. Parameter measured was net income generated from each model. Result of the study indicated that integration models of mulberry plant with livestock have their own uniqueness to be applied. The highest income for farmer was obtained when the whole mulberry plant was used as feedstuff for feedlot cattle (the P2 model). Income of Silkworm farmers also increased when applying the P1 model, which introduced two goats for each box of silkworm rose. But in a certain occasion, it was more beneficial for the farmers to harvest and dry mulberry plant then sells it for concentrate ingredient (the P3 model). In conclusion, the main factor to be considered in choosing one particular model to be implemented is mainly determined by ability of the farmers to procure cattle or goat to be raised in the mulberry plant???livestock integration model without ignoring the forecast of dry and rainy seasons

    The aim of this research was to examine the use of corn stover which was previously treated with fungi Trichoderma sp. (treated corn stover) and enriched with gliricidia leaves as feed for local goat. A completely randomized block design (CRBD) with four treatments and three blocks as replicates were applied. A total of 12 one year old local goats (Marica x Kacang) at a body weight 12.46. ± 1.64 kg, derived from Jeneponto districts were divided into three sampling groups. Each goat was placed in a metabolic cage 65 x 100 cm. One of four treatments was randomly given to each goat within every block. The treatments were A: 80% corn stover + 20% gliricidia leaves, B: 60% corn stover + 40% gliricidia leaves, C: 80% treated corn stover + 20% gliricidia leaves, D: 60% treated corn stover + 40% gliricidia leaves. The amount of feed offered to each goat was 3.5% of their body weight on dry matter basis. Results of experiment indicated that performance of the goats fed on treated corn stover was significantly better than those received untreated corn stover. The performance of the goats given 40% gliridia leaves was much better than those given with 20% gliricidia leaves regardless of their basal diets whether treated or untreated corn stover. In conclusion, treating corn stover with fungi Trichoderma sp. could improve nutritive value of corn stover for goats and its productivity could be further improved by 40% with gliricidia leaves supplements feed
