PENGGUNAAN SILASE PAKAN LENGKAP BERBASIS BATANG TEBU TERHADAP KONSUMSI, RETENSI N, ESTIMASI SÍNTESIS PROTEIN MIKROBA RUMEN DAN PERFORMANS SAPI PFH JANTAN
ABSTRACT: The main objective
of the research was to know the effect of silage complete feed based on
sugarcane stalk to N retention, estimated microbial protein synthesis and
performance of PFH steer and to find out an ideal proportion of sugarcane stalk
on silage complete feed which gave the best performance of steer in
economically prices.
Nine of male PFH steer age 10 – 11 months were used in randomized block
design (3x3) with initial body weight as covariance on total collection method.
The treatment were the proportion of sugarcane stalk and concentrate on silage
complete feed which made iso N/CP on 13% crude protein (SPL1 : sugarcane stalk
: concentrate = 60 : 40, added with urea 1.23 % ; SPL2 : sugarcane stalk :
concentrate = 50 : 50, added with urea 0.62 %; and SPL3 : sugarcane stalk : concentrate = 40 :
60, without urea). Parameters of the research were intake, N retention,
estimated microbial protein synthesis and daily weight gain.
The result showed that SPL1, SPL2, SPL3 have not significant effect
(P>0.05) to intake, N retention, estimated microbial protein synthesis and
daily weight gain but have significant effect (P<0.05) to organic matter
digestibility (OMD), and crude protein digestibility (CPD). Overall, SPL3 tends
give a better effect than the other feed treatment. SPL1 was an ideal treatment
for PFH steer because more economically from the price and gave performance
quite similar with other treatment. Economically value of SPL1 would be higher
when the price of sugarcane was less than Rp. 200.00/kg. It could be suggested
to consider the particle size of SPL, ensilage process and storage method for
the best result of SPL.
