Abstract

The study was conducted to evaluate the rumen degradability of soy bean meal when it was mixed with banana stem juice and was subsequently heated.  Banana stem juice was used as source of tanin to protect protein in soy bean meal from degradation in the rumen. The banana stem juice (in volume) was mixed with soy bean meal at three ratio, which were 1 : 1, 1:2 and 1 : 3 (w/v). These mixing was then heated at 60oC and 90oC. The heating was done in an oven. Sample from each treatment was then filled into polyester bag with porosity of 45 mm and the size of 5 x 9 cm. The bags were incubated in the rumen of fistulated sheep for 0, 2, 4, 8, 16, 24 and 48 hours. The experiment was carried out in factorial 3 x 2, with three levels of banana stem juice and 2 levels of heating and was arranged in completely randomized design. Untreated soy bean meal was also incubated used as  control. Degradation data of dry matter and crude protein at each incubation time was fitted into exponential equation,  P = a + b (1 - ect). Results shows that there was a significant interaction factor of stem juice ratio and heating on water soluble substrate (constant A) where heating at 90oC with ratio 1 : 2 (w/v) resulted in the highest a. The insoluble but fermentable substrate (B) was decreased by the increasing concentration of banana stem juice, while the rate of protein degradation of b fraction was lower compared to control. In conclusion, banana stem juice can reduce the rate of degradation of soy bean meal in the rumen. Key words: Degradation, Crude Protein, Soy Bean Meal, Banana Stem Juice

Abstract

The utilization of rumen undegradable protein, could increase supply of amino acids in small intestine to meet host protein requirement. To increase the utilization of feed protein, feed protein source which is highly degradable should be protected from degradation in the rumen. The objective of the study was to increase nitrogen retention through substitution of fish meal protein with soy bean meal protected by banana stem juice observed from rumen fermentation activities. The study used 18 late pregnant Sumatera Composite breed ewes. Rations consisted of fresh chopped elephant grass, supplemented with a commercial concentrate and mineral block in the form of Comin plus and different types of protein supplement as treatment diets. The type of protein supplements were: soya bean meal (RK), soy bean meal protected with banana stem juice (RKT) and fish meal (RTI). Treatment diets were offered during late pregnancy (from two months before to two months after partus), two weeks adaptation period was carried out before data recording. Design of the study used randomized complete block design. Results of the study show that rumen ammonia concentration in sheep fed on RKT was not significantly different either from RTI or from RK, however, the nitrogen retention was significantly (P < 0.05) different among the treatments (4.92 g/h vs 12.52 g/h; 17.11 g/h). Total VFA production or the proportion of C3, iC4, iC5 and nC5 was not significantly different (P > 0.05), however, proportion of C2 and nC4 was significantly different between diet treatment. Methane emission was higher (70.3 mM or 37.2% higher from total energy VFA) in diet RKT which is indicated that fermentation system was not efficient. It can be concluded the higher rumen ammonia concentration and lower nitrogen retention in protected soy bean meal supplement indicated that soy bean meal protected by banana stem juice in the ration was not able to substitute fish meal protein which is resistance from degradation in the rumen.
