In vitro evaluation of ruminal digestibility and fermentation characteristics of local feedstuff-based beef cattle ration

Background: Optimum productivity of beef cattle is achieved with adequate feed supply, both in quality and quantity. Consumption local feedstuff Neptunia plena L. Benth Leersia hexandra Swartz as a ration by the animal subject expected to promote cost efficiency production, well provide essential nutrition needs. Therefore, this research aimed evaluate dry matter digestibility (DMD), organic (OMD), N-NH3 volatile fatty acid (VFA) cattle. Methods: Feed rumen inoculum samples were prepared analyzed for their proximate contents. There five treatment groups based on diet received cattle. In vitro approaches used determine DMD, OMD, N-NH3 VFA cattle. The was conducted Laboratory Feed Nutrient Science, Faculty Animal Husbandry Agriculture, Diponegoro University, Semarang. The data using ANOVA at significance level 95%, Duncan Multiple Range Test. Results: results showed that highest DMD (P<0.05) derived from T5 (56.47%), followed T4 (56.45%) T3 (55.90%). T5=62.40% significantly generated OMD T4=61.95% T3=60.82%. This had value, namely 5.02 mM, compared T3=4.55 T4=4.50 T2=4.22 T1=3.99 mM. Furthermore, had T4, T3, T2, T1 with value 150.5, 133.0, 130.5, 130.0, 123.5 respectively. Conclusions: feedstuff-based contributed production.
