    Abstract

    Two step of experiment have been conducted in order to improve the nutritive value of low quality agro-industrial by-products as feed for ruminants. In the present experiment, the highest quality of ammoniated-rice straw as assesed by in vitro methods in the previous experiment, was combined with various level concentrate. The concentrate consisted of 25% rice bran, 8% cassava waste, 5% tofu waste dan 2% blood meal and 60% rice straw. For experimental rations were allocated according to compeletly randomized design, its treatment was replicated in four replications. One rumen cannulated cattle has been used as source as rumen fluid for in vitro digestion trials. The following experimental diets : *60% ammoniated-rice straw + 40 concentrate and Ca, P, Mg and S supplementation (ration A) : 60% ammoniate-rice straw + 40 concentrate and 1.0 of Ca, P, Mg and S supplementation (ration B) : 60% ammoniate-rice straw + 40 concentrate and 1.5 of Ca, P, Mg and S supplementation (ration C) : 60% ammoniate-rice straw + 40 concentrate and 2.0 of Ca, P, Mg and S supplementation (ration D). Objective of the present experiment was to find the best the combination of mineral suplementation consist it Ca, P, Mg and S of rice straw or 60% ammoniated-rice straw + 40 concentrate and 1.5 of Ca, P, Mg and S supplementation (ration C). The result showed that ratio of ammoniated rice straw and concentrate in ration significantly (p<0.05) affect the digestibility of nutrients. Digestibility of dry matter, organic matter, crude protein, NDF and ADF were significantly higher (P<0.05) in ration D than those A, B and C ration. However, the rations, in which the ruminal pH, concentrations of ruminal NH3-N and total VFA were almost canstant for all the treatment rations. The concentrations of NH3-N ranged from 7.27 – 7.76 mg/100ml, total VFA 60.12-87.90 mM and ruminal pH ranged from 7.03-7.12. from these results it could be concluded that ration C of ammoniated rice straw and concentrate in the ration with supplementation of 1.5 Ca, P, Mg and S affected nutrient digestibility and characteristics of ruminal condition. Key word : Mineral supplementation, degradability, ruminal condition
