Evaluasi in vitro ampas kurma terhadap kecernaan dan daya hidup mikroorganisme rumen sebagai potensi pakan alternatif kambing perah

Abstract

Date fruit waste (DFW) is a food industrial waste which was considered to be a nutritious feed, especially as an alternative feed of dairy goat. The use of DFW in the ration was not evaluated in the rumen fermentation and digestion. The general aim of this experiment was to evaluate the advantage of DFW in dairy goat ration by observing its digestibility in the rumen and its flavonoid on rumen microbial population. The results showed the addition of DFW increased dry matter digestibility and propionate proportion, and it had significantly change of ratio acetate:propionate compared than control. Furthermore, there were no effects to the concentration of N-NH3, proportion of butyrate and acetate, methane production, and organic matter digestibility. There was no effect of DFW on the population of total rumen bacteria and protozoa. As conclusion, addition of DFW can be allowed into dairy goat ration up to 50% of 40% concentrate when containing 30% Elephant grass and Indigofera sp.
