Livestock feed availability is affected by more green field conversion to residential, industrial, and transportation areas. To anticipate the limited land for animal feed plants, and to reduce the environmental pollution. Waste utilization for animal feed has important and meaning in efficient farm development. Rumen content and sludge are wastes available in high number and even can contaminate the environment. Both animal wastes are rich in essential amino acid and potential as animal feed. The use of cellulolytic bacteria (Cellulomonas sp.) starter in the fermentation is expected to be able to degrade crude fibers and to increase protein content. This study aims to evaluate the nutritive value of rumen content and sludge fermented using Cellulomonas sp. that the best level of microbe addition and incubation to make feed material mixture for rabbits. The study applied factorial experiments in completely randomized design with 4 replications. First factor was cellulolytic bacteria colony concentration (K), K1 = 107 cfu/g dry material, K2= 108 cfu/g dry material, and K3 = 109 cfu/g dry material, respectively, and second factor was incubation period (L) at room temperature, L1 = 6 days, L2 = 8 days, and L3 = 10 days, respectively. Results revealed that rumen content and sludge mixture fermented at the bacteria concentration of 107 cfu/g dry material and 8-day incubation gave an optimal outcome based upon its nutrient content for rabbit feed. In addition, the use of these wastes could also solve quality and sustainable feed availability problems and reduce environmental pollution impacts. © 2016, Sphinx Knowledge House.
