Abstract

Adequate forage amounts in ruminant animal are necessary for proper ruminal function in dairy cow. This study was carried out to determine the effect of total mixed fermentation feeds made by different green forage crops and grain processings on chemical compositions, RFV (relative feed value) and ruminal characteristics in sheep. The experiment was arranged in a split plot design with 4 replications. The main plot consisted of 6 kinds of green forages (corn, grass, rye, rape, alfalfa and oat) and the sub plots three different grain processings such as non-milling, half milling (7mm mesh over), and regular milling (7mm mesh below). And the different TMFFs (total mixed fermentation feeds) were analyzed for chemical composition and fed to 8 ruminally fistulated sheep for ruminal charactics and palatability. RFV, daily feed intake, acetate/propionate ratio of the rape-TMFFs were higher compared with the other treatment. Ruminal content of VFA (volatile fatty acid) of corn-TMFF was highest as 90.19 mmol% and pH of the feed was lowest as 3.82. But, acetic acid, propionic acid and butyric acid were no difference among treatments. In conclusion, the effect of grain proceeding was not appeared but if consider of only RFV, palatability and dry matter disappearance, grade of TMFF was improved in order of rape-, corn-, alfalfa-, grass-, oat- and rye-TMFF.
