Abstract

The purpose of this study was to determine young maize stover flour production resulted from biodegradation Pleurotus ostreatus fungi with fiber digesting enzyme on broiler feed implications. Materials used in this research were young maize stover (60-70 days), Pleurotus ostreatus fungi, urea (CO-(NH2)2), readily available carbohydrate, aquadest and alcohol. The method used ANOVA test with five treatments and four replication: R0 = control (without fermentation), R1 = 10g Pleurotus ostreatus/kg TTJM; R2 = 20g Pleurotus ostreatus/kg TTJM; R3 = 20g Pleurotus ostreatus/kg TTJM and R4 = 40g Pleurotus ostreatus/kg TTJM. The result showed best effect of crude protein R2= 32.33, best effect of crude fat R4= 18.59, best effect of crude fiber RO= 119.70, and best effect of energy (kkal) R4= 20682.59. The study concluded that the increasing crude protein and crude fat also decreased crude fiber content as a result of fermentation using Pleurotus ostreatus. The energy content of maize stover had no significant effect due to fermentation. Key words : fermentation, enzyme, maize stover, broiler

Abstract

Copra meal is by-product of oil extraction that is produced in large quantity and relatively cheap in Indonesia. However, its high cellulose becomes obstacle for poultry diet. Two studies was conducted to optimize the utilization of copra meal by producing crude enzyme that matched with copra meal using solid state fermentation method with various doses and incubation time that mixed with Pleurotus ostreatus (PO) and Trichoderma viridae (TV). In the first study, copra meal was fermented with 4 levels of inoculum (L0 = no inoculum; L1 = 17.7 CFU/g of TV and 175.00 CFU/g of PO per kg of copra meal; L2 = 35.4 CFU/g of TV and 218.75 CFU/g of PO per kg of copra meal; L3 = 53.1 CFU/g of TV and 262.50 CFU/g of PO per kg of copra meal and 4 incubation time (W1= 4 days; W2 = 6 days; W3 = 8 days; and W4 = 10 days). Parameters measured were crude protein, crude lipid, crude fibre and gross energy. A completely randomized factorial design was used in the study. In the second study, crude enzyme was produced from the best results found in the first study. A method of Jacob and Prema (2006) was used to produce enzyme. Meanwhile, activity of cellulase was measured based on the method of Omojosola (2008). The results showed that factor of inoculum level was found significantly increased protein content and gross energy but decreased crude lipid and crude fibre of the mixed fungi-fermented copra meal. Incubation time did not affect protein content but significanly affected crude lipid, crude fibre and gross energy. Interactions between inoculum level and incubation time was found in crude lipid, crude fibre and gross energy contents of mixed fungi-fermented copra meal. Activity of cellulase was 0.71 g glucose/l.   Keywords : Fermentation, Pleurotus ostreatus, Trichoderma viridae, inoculum level, incubation time, cellulase activity
