Perbedaan Laju Alir Partikel Pakan Berbagai Pakan Serat dalam Sistem Rumen Sapi
ABSTRACT: The differences of passage rate particles is
considerably influenced by different feed consumption relating to the nature of
feed, types of animals, and physiological status of animals. The purpose of
this experiments was to measure differences of passage rate feed particles at
various crude fiber feed in cows’ rumen. This experiment used two cows of
fistulated crossed breed Frisian Holland (PFH), non-productive with the age of
4-5 years. Feed observed in this experiments were peanut straw, corn straw and
sugar cane straw and fed as single feed. Method applied to measure passage rate
was chrome mordanse/chrome and NDF as marker introduced through fistulated
rumen. All data were analyzed by using regression. The value of passage rate
(Kp) was about 3,7% per hour for peanut straw, and 2,5% per hour for corn straw
and sugar cane straw. Kp value of peanut straw was higher than that of corn
straw and sugar cane straw. The highest value of Kp for peanut srtaw was due to
better quality of peanut straw compared to corn straw and sugar cane straw in
which peanut straw contained high level of protein and low level of Neutral
Detergent Fiber (NDF). The differences of chemical composition of crude fiber
feed from peanut straw with high level of protein and low level of NDF compared
to corn straw and sugar cane straw resulted in degradation of feed by microbial
rumen was higher, low rumination. It caused higher passage rate of feed.
