Abstract

The present work was aimed to study the effect of temperature and time of incubation of palm kernel cake fermented with A. niger on the activity of enzymes and nutrient content. The experiment was arranged in completely factorial design of 3x3 patterns. The first factor was three levels of temperature of 30, 37, 41oC, the second were three different times of incubation of 4, 6, and 8 days. Parameter observed included cellulose and protease activities, crude protein and crude fiber contents. Results showed that there was a signifficantly interaction between temperature and incubation times (P< 0,01) on enzyme activity of cellulose and protease and crude protein, but time of fermented were significantly (P<0,05) on crude fiber of palm kernel cake fermentation. It was concluded that the optimum temperature and time of incubation were 30 oC and 6 day, which gave the highest content of crude protein (27,70 %) and crude fiber (17.73 %).

Abstract

The aims of the present experiment were to study the effect of substrate composition and time period of incubation on the nutrient composition of chicken feather meal fermented with EM4. The experiment using completely: randomized design was aranged in 3 x 3 factorial designs with there replicates. The treatment were substrate composition (A) (A1 100% feather meal + 0% rice bran, A2 90% feather meal + 10% rice bran, A3 80% feather meal + 20% rice bran), and time of incubation (B) (9,12 and 15 days). Parameters observed were crude protein, crude fiber, crude lipid and BETN. Results showed that there was no interaction (P>0,05) between substrate composition and time of fermentation on crude protein, crude fiber, crude lipid and BETN, substrate composition and time of incubation gave significantly (P<0,05) effect on crude protein, crude fiber, crude lipid and BETN of the fermented products. It was concluded that the optimum substrate composition and incubation time was found by using 80% feather meal + 20% rice brand and 15 days of incubation time, which gave the highest crude protein of 56,37% and low crude lipid of 23,95 % and crude fiber of 3,4 %.
