Digestibility of gramineous and leguminous hays fed to sheep



Digestibility of gramineous and leguminous hays fed to sheep



Cyprus Agricultural Research Institute Technical Bulletin (69): 1-4



Digestion trials were conducted with mature Chios wether sheep to determine digestibility coefficients of the major organic components of barley, common vetch, woollypod vetch, fodder peas, sudax and alfalfa hays. There were significant differences in crude protein (CP), true protein, crude fiber (CFi), neutral and acid detergent fiber, lignin and digestible energy (DE) contents, and in-vitro D-values between leguminous and gramineous hays. Voluntary intake of alfalfa hay was higher than that of the gramineous hays (67 vs. 46 g DM/kg W0.75). Barley hay had the lowest digestibility for DM, organic matter (OM), CP and gross energy (GE) followed by sudax hay. Differences within leguminous hays, though sometimes significant, were relatively small. Regression equations relating OM, CP, GE and CFi digestibility to DM digestibility were calculated for all six hays. Using the DE and CP values obtained in this study, it was estimated that 1 kg of leguminous hay can replace approximately 1 kg of barley hay with an extra saving of 205-260 g of imported soyabean meal, which would have to be fed with the barley hay.
