Pemberian Pakan Serat Sisa Tanaman Pertanian (Jerami Kacang Tanah, Jerami Jagung, Pucuk Tebu) Terhadap Evolusi pH, N-NH3 dan VFA Di dalam Rumen Sapi
ABSTRACT: The goal
of this study
is to evaluate the condition of fermentation
in the rumen of cows by
administration of 3
types of feed
fiber agricultural crop residues
(Groundnut Straw (GS), Corn Straw (CS) and Sugarcane Tops
(ST)). Single feeding wascarried out
at 2 Holstein
Friesian Crossbred (HFC) cows
with the age
of 4-5 by fistula rumen.This study was conducted 20
days and with a 14-day
adaptation period. At
the end of the
adaptation period, rumen
fluid was collected
to measure pH, N-NH3and
VFA based on
feed treatment percow. Collection
of rumen fluid
was simultanous conducted for
24 hours at
27 time points decision.The
results of the
experiment showed that the level of pH for GS, CS and ST was 7.02 +
0.29; 6.54 +
0.16 and 6.54
+ 0.14 respectively. The
level of N-NH3
was 4.90 + 2.10
mg/100 ml of
rumen fluid; 7.36
+ 3.10 mg/100
ml of rumen fluid;
2.26 + 0.85
mg/100 ml of
rumen fluidfor GS, CS and ST, respectively. Meanwile, the level of VFA
was 57.44 + 12.75 mmol/l ml, 64.84 + 10.82 mmol/l and 44.13 + 6.66 mmol/l ml of
rumen fluid, respectively.
