Utilization of Fermented Soy-Milk Waste with Aspergillus ficuum in Broiler Ration

Abstract

Soy-milk waste (SMW) has the potential to be used as feedstuff, particularly for poultry. SMW must be treated with Aspergillus ficuum prior to fermentation. Objective: An experiment was conducted to evaluate the use of fermented SMW (F-SMW) with Aspergillus ficuum in broiler ration. Materials and Methods: One hundred and forty-day old broiler chicks (DOCs) were used in this study. Iso-energy (3000 kcal/kg) and iso-protein ration (22 percent) were assigned to this study using a completely randomized design (CRD) with 5 treatments and 4 replications. The treatments were as follows: 1) 0 percent F-SMW (control diet), 2) 15 percent F-SMW, 3) 20 percent F-SMW, 4) 25 percent F-SMW and 5) 30 percent F-SMW in broiler ration. The parameters calculated in this study were feed intake, body weight gain, feed conversion body weight, carcass weight, carcass proportion, abdominal fat ratio, nitrogen retention, and crude fiber broiler digestibility. Result: feed intake, body weight gain, feed conversion body weight, carcass weight, carcass proportion, abdominal fat ratio, nitrogen retention, and crude fiber broiler digestibility significantly decreased (P<0.01) for all treatments. Conclusion: Up to 25% of F-SMW can be used for broiler ration.
