Peningkatan Kualitas Tongkol Jagung Teramoniasi Melalui Teknologi Fermentasi Menggunakan Starter Komersial Terhadap Produksi Vfa Dan Nh3 Rumen Secara in Vitro

摘要

The objective of the research was to know the effect of different combination level of starter commercial and time of periode fermentation on production VFA and NH3 Rumen Content In vitro to increase quality of corn cob, research was conducted in Technology Animal Nutrition Department and Feed Animal Nutrition Department, Animal Science Faculty of Diponegoro University. Level of starter commercial was 0, 1 and 2 % BK, and time periode of fermentation was 0, 1, 2, 3 and 4 week. Data collection consist of production VFA and NH3. Data then was analyzed using analysis of variance (ANOVA) based on the completely randomized design. To compare among treatment means using Duncan Multiple Range Test. Result of this research showed that not be found interaction of combination level starter commercial and time of periode fermentation to product VFA, whereas on production NH3 showed interaction combination level starter commercial and time of periode fermentation on corn cob. The utilization of added starter commercial 2% and 4 week time of period showing the best production VFA and NH3 on corn cob amonniated by fermentation.
