Kadar Protein dan Urea Darah Kambing Perah Peranakan Etawa yang Diberi Wafer Pakan Komplit Berbasis Limbah Agroindustri dengan Suplementasi Protein Terproteksi

Abstract

The objectives of the research were to evaluate level of supplementation protected protein on complete feed wafer based on agroindustrial by-product to blood protein and urea concentration in Ettawa Crossbreed lactation goat. The availability of feed continously was needed to increase productivity of livestock. The using agroindustrial by-product was one of requirement feedstuff for the goat but, the using of the matter had a problem that less protein so, needed protein suplementation. Goat had microbe in the rumen and the microbe degraded feed protein become NH3 so, protein suplementation was important to protect. This research used complete feed that formed wafer with suplementation level of protected protein. The function form of wafer was to increase long live of storage and decrease of feed voluminus. This research was done with block randomize design with three of treatments suplementation level of protected protein 0%, 4% and 8% and five of blocks to lactation month, group as repetition. This research was done during 12 weeks with detail 4 weeks of wafer production, 2 weeks of adaptation, 2 weeks of prelimiary and 4 weeks of treatment. The collecting data were taken on the last week of treatment. The result of the research showed that the blood protein was significantly (P<0,05) affected by the protected protein supplementation level in complete feed wafer based on agroindustrial by-product. Whereas, blood urea was not significantly (P>0,05) affected by the protected protein supplementation level in complete feed wafer based on agroindustrial by-product. Level of 4% was the good suplementation in complete feed wafer based on agroindustrial by-product was seen of blood protein and urea
