The study was conducted to determine the effect of protected soybeanmeal with banana juice as rumen undegradable protein source to the rumen fermentation. Fourteengrowing lambs with average live weight of 18.6 ± 2.2 kg were grouped according to early weight. Threediets were isonitrogenous and isoenergy (CP 18% and TDN 75%) with different level of protectedsoybean meal with banana juice, R0 = control diet with 100% of untreated soybean meal, R50 = R0, with50% of protected soybean meal, and R100 = R0, with 100% of protected soybean meal. Dry matter ofdiets was given approximately 3.5% of live weight. The result showed that pH value, NH 3 -Nconcentration, purine base, total bacteria and total VFA were not effected by level of protected soybeanmeal with banana juice (P>0.05). It was concluded that substitution of protected soybean meal withbanana juice as rumen undegradable protein did not affect rumen fermentation.091 PURNOMOADI, A.Effect of soybean pulp (soy-sauce industrial byproduct) in ration on chewing efficiency of eating andrumination of buffalo heifers.

The buffaloeswere grouped into two: first group was fed napier grass and commercial concentrate (NC-O group), whilesecond group was fed napier grass, concentrate and soybean pulp (NC-SP group). Napier grass wasprovided after 7 days wilted. Napier grass and concentrate were given at ratio 70:30. For NC-SP group,the concentrate was composed by 75% commercial concentrate and 25% soybean pulp. The feed was setto meet the dry matter (DM) requirement at 2.5% of live weight. Eating behavior was measured from 3days continuously observation. Chewing number was accounted by halter equipped with tape switch injaw side and was recorded in every 1/10 second in connected PC. The results showed that soybean-pulpgave a similar on DM1 (NC-O : 5.659 vs NC-SP : 5.680 g/d) and rumination time (385 vs 389 min/d).However, soybean pulp tend to decrease eating time (561 vs 437 min/d), total chewing activity (49,986 vs41,907 chews/d), chewing for eating (27,887 vs 21,797 chews/d) as well as chewing for rumination(22,099 vs 20,110 chews/d). The lower eating time in similar DM1 for NC-SP showed that soybean pulpincreased palatability, while the lower rumination time showed that soybean pulp increase degradability offeed in rumen.44
