PERTAMBAHAN BOBOT BADAN HARIAN SAPI BRAHMAN CROSS PADA BOBOT BADAN DAN FRAME SIZE YANG BERBEDA
ABSTRACT: This research was
conducted at PT. Widodo Makmur Perkasa Feedlot on August until October 2011.
The purpose is to assess average daily gain of Brahman cross with frame
sizetype(M andL) anddifferentbodyweights(<300 kg, 300-350kg, and>350 kg)
and theinteractionbetween theframe sizeanda differentbodyweights.The materialsused
for this research were 3052 head SteerBrahmanCrosscattle with initial body
weights250 kg-380 kg. This research was using study casus. data obtained was secondary
data. The obtained data was analyzed using Completely Random Design (CRD)
inbalanced factorial.The result showed that frame size has significant effect (P<0,01)
on Brahman cross steer average daily gain. The average daily gain is 1.15 ± 0.367
kg for M frame size group and 1.3 ± 0.354 kg for L frame size group. Initial body
weight was also has a significant effect on Brahman cross steer average daily gain.
The average daily gain of <301; 301-350; and >350 group were 1.329±0.366;
1.22±0.348; and 1.13±0.357 kg. The interaction between frame size and initial
body weight give significant effect on Brahman cross steer daily gain. The gain
of <301kg of initial body weight group with L framesize is 1.34 kg/day and M
frame size is 1.29 kg/day. The gain of 301-350kg of initial body weight group
with L frame is 1.31 kg/day. And the gain of >350kg of initial body weight
group with L frame size is 1.21 kg/day and M frame size is 0.93 kg/day.
