Abstrak: This study was aimed
to determine the effect of protected soybean groats-Lemuru fish oil in the diet
on performance of males Simental Ongole Crossbred. The materials used in this
study were 9 heads of males Simental Ongole Crossbred cattle with an average initial
weight of 467.55 ± 30.89 kg. The experimental design used was a completely
randomized design (CRD) consisting 3 treatments and 3 replications. The
treatments were P0 = 30% rice straw fermentation + 70% basal concentrate; P1 =
30% rice straw fermentation + 55% basal concentrate + 15% ogf unprotected
soybean groats-lemuru fish oil, and P2 = P1 = 30% rice straw fermentation + 55%
basal concentrate + 15% of protected soybean groats-lemuru fish oil. Data were
analyzed using analysis of variance followed by Duncan's Multiple Range Test.
The results showed that the use of protected soybean groats-lemuru fish oil in
the diet did not affect the initial body weight, final body weight, average
daily gain, FCR and FER. Additionally, the treatment significantly affected dry
matter intake and the income of the feedlot has increased. Conclusions of this
study was the use of 15% protected soybean groats-lemuru fish oil in the diet
increased production performance and income of male simental Ongole Crossbred
feedlot.
