Influence of Non-fibrous Carbohydrate and Degradable Intake protein and Ruminal Fermentation ,Nutrien Digestion and performance of Local Sheep

The objective of current study was to evaluate the impact dietary non-fibrous carbohydrate ( NFC) and ruminally degradable intake protein (DIP) concentration have on ruminal fermentation , nutrient digestion and performance of local sheep. The animal had a mean of liveweight 19.80 ±1.55 kg. four diets ,arranged in a 2x2 factorial ,were formulated to contain either 40 or 50 % NFC and 50 or 60 % of dietary crude protein as DIP .dietary DM contained 25 % Indonesian field grass and 75 % concentrate. Solvent –extracted or formaldehyd 2 % -treated soybean meal were used to alter DIP and corn or soybean hulls to alter NFC level. Percentage of energy and NDF digestion was similar ( p<0,01) as DIP level decreased in the diets. The soybean hulls was fermentable and total VFA concentration in the rumen increased ( p<0.01), but N-NH3 concentration was decreased ( p<0.01) as DIP level decreased in the diets. Daily live weight gain ( 146.29±25.84 g) and body composition ( fat, water , protein and mineral) was similar ( p
