Comparison of In vitro Gas Production, Metabolizable Energy, Organic Matter Digestibility and Microbial Protein Production of Some Legume Hays

The aim of this study was to compare the chemical composition, in vitro gas production, metabolizable energy (ME), organic matter digestibility (OMD) and microbial protein (MP) production of the legume hays from alfalfa (Medicago sativa L.), common vetch (Vicia sativa L.), pea (Pisum sativum L.), birdsfoot trefoil (Lotus corniculatus L.) canola (Brassica napus L.). Gas production was determined at 0, 3, 6, 12, 24, 48, 72 and 96 h. There were significant differences among legume hays in terms of chemical composition (P<0.05). The crude protein content of legume hays ranged from 16.82 to 20.79%; ether extract from 3.46 to 5.16%; crude ash 5.74 to 8.37%; neutral detergent fiber (NDF) from 36.05 to 46.00%; acid detergent fiber (ADF) from 26.60 to 37.79% and acid detergent lignin (ADL) 7.41-13.23%. Chemical composition had a significant effect on the gas production kinetics (P<0.05). Total gas production ranged from 68.37 to 75.40 ml/200 mg DM, organic matter digestibility (OMD) from 71.77 to 78.29%, ME from 10.68 to 11.22 MJ/kg DM and microbial protein (MP) production from 110.89 to 124.31 g/kg DM. The total gas production, OMD, ME and MP of canola hay was significantly lower than the other legume hays (P<0.05).
