Digestive nutrientsratio of some common feed raising buffaloes by in vivo method
Determination of the digestive nutrients of some common feeds is done byin vivo experiments, used 4 domestic buffaloes, average age 30 months with average weight 280kg. The study used 11 types of feed including: 5 types of green forage (VA06 grass, Elephant grass, P.hamil grass, Ruzi grass and Decumbens grass); 3 types of dry forage (Dried straw, dried Decumbens grass, dried Ruzi grass) and 3 types of concentrate feed (cornmeal, crushed rice, rice bran). The experiment wasdone in 15 days for each type of feed (10 days for adaptation with new feed and 5 days for experiment) . The results showed that digestibility rate of the dry matter, crude protein; NDF and ADF of green forage group are 55.30 – 66.19%; 50.75 – 74.08%; 46.08 – 64.57% and 40.56 – 53.89%respectively. The dry forage group are 44.69 – 57.88%; 38.89 – 66.64%; 51.82 – 60.07% and 38.78 – 47.55% respectively. The concentrate feed group are 68.65 – 74.99%; 64.18 – 83.46%; 75.56 – 82.13% and 45.98 – 61.44% respectively. The organic matter digestibility and metabolic energy value of green forage group are 59.41 – 67.08% and 7.76 – 8.44 MJ/kg DM respectively. The organic matter digestibility and metabolic energy value of dry forage group are 52.41 – 61.39% and 7.28 – 7.87MJ/kg DM respectively. The organic matter digestibility and metabolic energy value of concentrate group are 73.26 – 80.05% and 9.19 – 11.63 MJ/kg DM respectively.
