PENGARUH PENAMBAHAN TEPUNG KIAMBANG (SALVINIA MOLESTA) FERMENTASI DALAM RANSUM TERHADAP PERFORMA KARKAS DAN LEMAK ABDOMINAL AYAM BROILER

Abstrak

Kiambang (Salvinia molesta) is an aquatic weed that floats on the surface of rice field, swamps, ponds, rivers,
ditches and lakes. Kiambang can be used as an alternative feed for broilers. Kiambang contain high crude fiber, so a
fermentation process is carried out to reduce crude fiber and improve the quality of kiambang. Kiambang which is
processed into flour and has been fermented contains crude protein 9,5%, crude fat 0,22%, crude fiber 21,07%,
metabolic energy 3097.40 kcal/kg, calcium 2,2% and phosphorus 0,295%. This study aims to determine the effect of
fermented kiambang flour in the ration on final weight, carcass weight, carcass percentage, abdominal fat weight and
abdominal fat percentage. The method used in this study was an experiment with a completely randomized design
(CRD) consisting of five treatments and four replications. The treatment was the addition of fermented kiambang flour
(Salvinia molesta) into the basal ration with levels of 0%, 3%, 6%, 9% and 12%. Parameters measured were final body
weight, carcass weight, carcass percentage, abdominal fat weight and abdominal fat percentage. The results showed
that the addition of fermented kiambang flour (Salvinia molesta) up to 12% in the ration had no significant effect
(P>0.05) on final body weight, carcass weight, carcass percentage, abdominal fat weight and abdominal fat
percentage. The conclusion of this study was that the addition of fermented kiambang flour (Salvinia molesta) to level
of 12% in the ration can maintain final body weight, carcass weight, carcass percentage, and cannot reduce abdominal
fat weight and abdominal fat percentage.
