Effects of Length of Cut and Leaf Surface Treatments on Digestibility of Fresh Forage1
- Warren G. Monson and
- Glenn W. Burton2
Digestibility of leaves of pearl millet, napiergrass, and bermudragrass was increased by several treatments. After 48 hours in rumen fluid, average dry matter losses from leaves cut to lengths of 2.5, 1.2, .6, and .3 cm were 17.1, 25.9, 30.6, and 42.8%, respectively. When leaves were pressed on a rough surface or abraded with sand paper to break the cuticle, average dry matter losses were from 2.5 to 5 times (mean = 3.2) the losses from intact leaf sections. Increasing the cut surfaces or rupturing the cuticle enhanced the digestion of fresh forage by rumen micro-organisms.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
