Abstract

Abstract: The objective of research was to know the levels of digestibility and fermentability between breeders feed and iso-protein-based feed. A randomized Complete Design with 5 treatments and 4 replications based in the iso-protein with different levels of Total Digest Nutrient (TDN) was employed. Research on amber hay and concentrate combined into "Complete Feed" was conducted. The treatment with T0 = Complete feed (6% CP+ 60% TDN), T1 = Complete (12% CP+ 60% TDN), T2 = Complete feed (12% CP+63% TDN), T2 = Complete feed (12% CP+ 66% TDN) and T4 = Complete feed ((12% CP+ 69% TDN) was given. The parameters observed were dry matter digestibility (DMD), organic matter digestibility (OMD), volatile fatty acid (VFA), NH3, dry matter intake, CP intake, TDN intake, daily weight gain (DWG), and feed efficiency. The result of complete feed application on Simental Crossbreed Intake of DM T0 and T2 was significantly different, but the CP intake and DWG was not significantly different. TDN intake, conversion, and feed efficiency of feed T0 to all treatments were significantly different (P <0.05). Feeding is recommended using CP 12% and TDN 63% (T2). The results showed that vitro feed analysis was not significantly different (P> 0, 05%) in terms of DMD, OMD, NH3 and VFA values.
