Abstract

Dairy cattle has a capability to produce a high yield and milk quality by feeding a Total Mixed Ration, TMR. Along with a well ration formulation, moisture content  and particle size of fiber may affect feed intake of dairy cattle . The objective of this study was to identify the optimum levels of moisture and  particle size. The experiment was randomize completely designincluded physically effective NDF (peNDF) 3 levels as 20, 25, and 30% and moisture contents as 40, 50, and 60 % of TMR.DM. The result indicated that both peNDF and moisture content were significantly difference among treatments in IVDMD, IVNDFD, and IVADFD. The feed digestion of IVDMD had affected by particle size that the optimum sizes were 20-25% during the first week of fermentation. Fiber digestion of IVDMD and IVADFD had affected by moisture content and fermentation period. Consequencely, peNDF 20-25% and moisture content 50-60% together with fermentation period during 7-21 days were promote the best of feed digestion.
