Produk Metabolisme Rumen pada Sapi Peranakan Ongole Fase Tumbuh
ABSTRACT: The utilization of
fermented fibrous waste material had improved the product of rumen metabolism
in vitro, nevertheless, it was not always the same result if treated on animal,
in vivo. An experiment had been conducted to investigate the result of the in
vitro trial to the growing male cattle of Ongole Grade. The experiment had been conducted by experimental
method using twelve (12) growing male cattle of Ongole Grade. The trial was conducted in Completely
Randomized Block Design, during seven months period, three months adaption, two
weeks preliminary, three months feeding trial and two weeks digestion
trial. The treatment tested were: R0 =
control ration, non fermented; R1 = mesh type fermented and R2 = pellet type
fermented. The variables measured were: the production of Total Volatile Fatty
Acid (T-VFA); asetate (C2), propionate (C3), butyrate (C4). The result shown that the treatment,
biological and physical, of complete feed, does not influence on the production
of T-VFA as well as on the composition (C2, C3 and C4).
Nevertheless based on all the variables measured, the biological treatment
with fermentation tends to increase the production of rumen metabolism, and the
highest result of the products of T-VFA = 112,43 + 17,2 mM/L, C2 = 40,46 + 8,98
mM/L, C3 = 34,57 + 7,35 mM/L, C4 = 31,17 + 7,35 mM/L, were resulted from pellet type of complete
feed. The result of experiment concludes
: (1) based on the production of VFA as well as its composition, and the
balance of C2 / C3, the utilization of complete feed both mesh and pellet type
increases the efficiency of energy utilization on the growing male of Ongole
Grade Cattle; (2) based on rumen
metabolism product, the recommended complete feed for growing male cattle of
Ongole grade is in the form of fermented pellet.
