Extract

Many non-forage fibrous sources (NFFS) such as beet pulp (BP) contain more NDF than some forage sources, and have been successfully used in dairy rations to replace a portion of the effective or physical effective fiber (peNDF) that is normally provided by forages. However, BP has limited forage replacement value and effectiveness factor of 0.40 (fraction of NDF) versus 1.0 for forages (Mertens, 1997). In addition, Mertens (1997) suggested that the physically effectiveness factor of ground and pellet were 0.40 and 0.30, respectively. However, the effects of BP when substituted with different feed sources in TMR are variable that depend on chemical composition, types and physical characteristics. The objective of this experiment was to measure the effects of three types of BP on intakes, digestibility, and chewing activity and performance of Holstein dairy cows.
