ABSTRACT
Azolla microphylla has advantages as feed ingredients for poultry because it proliferates and has high protein but contains high fiber. Therefore, fermentation with lignocellulolytic fungi was carried out to improve the nutritional quality of Azolla microphylla. This research has 2 phases. Phase 1, determination of the best types of lignocellulolytic fungi on the nutrient quality of fermented Azolla microphylla. This study used an experimental method with a Completely Randomized Design (CRD). The treatments were the types of fungi, namely Lentinus edodes, Pleurotus ostreatus, and Phanerochaete chrysosporium, and six replications. The parameter measured: cellulase activity, crude fiber, fiber digestibility, crude protein, and nitrogen retention. The results of phase 1 showed that the types of fungi had a very significant effect (P <0.01) on the nutrient quality of fermented Azolla microphylla. Fermentation of Azolla microphylla with Lentinus edodes and Pleurotus ostreatus gave the best products. Phase 2. Application Fermented Azolla microphylla (AMF) in the diet on broiler performance. Fermentation with Lentinus edodes has high amino acids, especially glutamic acid, increasing the palatability of broiler . The research method used a completely randomized design (CRD) consisting of 5 treatments and four replications. The treatments were the use of AMF in the diet: 0%, 10, 15, 20, and 25% AMF. The results of phase 2 showed that the treatment had a very significant effect (P<0,01) on feed consumption, body weight gain, carcass percentage, and carcass meat taste but gave no considerable impact (P>0,05) on feed conversion and abdominal fat percentage. The conclusion of phase 1 was the fermentation of Azolla microphylla with Lentinus edodes, and Pleurotus ostreatus gave the best products. The decision of phase 2, the use of Azolla microphylla fermented with Lentinus edodes, can be used up to 20% in the diet and can maintain the performance of broilers.
