THE EFFECT OF REPLACEMENT OF ELEPHANT GRASS WITH COFFEE SKIN IN THE COMPLETE COMPOUND SILASE ON THE RUMENT METHODISM AND DAMAGE IN GOAT LIVESTOCK

The availability of forage for goats for cattle is increasingly limited as agricultural land and plantations are increasingly narrowed. Coffee fruit skin is agricultural waste that has the potential as an alternative food source to replace fresh forage. The content of nutrients found in the skin of coffee fruit such as; crude protein at 10.4%, crude fiber at 17.2% and metabolic energy at 14.34 MJ/kg relatively comparable to grass nutrients. Until now, coffee bean skins have not been able to be used as animal feed due to various obstacles such as high content of lignin and silica which inhibits rumen microbes in digestion. The use of coffee husks above 20% in the ration can reduce digestibility in vitro. Based on the above problems, it is necessary to process it physically, chemically and biologically to be able to increase the digestive value of the coffee skin. One technology that can be implemented is complete silage ration technology by adding a protein or energy source. Elephant grass is one of the feed ingredients that can be used as a silage material that has a protein content that is almost the same as coffee skin. Information about the use of coffee skins as a complete ration silage material is still limited. Based on the above problems, it is necessary to conduct a study entitled The Effect of Replacement of Elephant Grass with Coffee Skin in Complete Ration Silage on Rumen Metabolism Products and Digestibility in Goats. This study aims to determine: 1) Effect of replacement of elephant grass with coffee skin in complete ration silage on rumen metabolite products of etawah crossbreed goats, 2) Effect of replacement of elephant grass with coffee skin in complete ration silage on digestibility and absorption of sutrients in etawah crossbreed goats. The results of this study can utilize plantation waste in the form of coffee skin as a substitute for elephant grass.
