udThe high protein feeds such as soybean meal, fish meal and palm kerneludcake are considered to be not optimal utilized by ruminant. This due to highudprotein degradation in the rumen that may decrease the efficiency of utilization ofudfeed protein. Most of the protein is converted into NH3 by the microbe, althoughudthe levels of NH3 is sufficient for microbial synthesis. One effort to protect feedudprotein from rumen degradation is by protecting feed proteins with formaldehyde.udThis research was conducted to investigate the effect of using protectedudsoybean meal (SBM), fish meal (FM), palm kernel cake (PKC) on pH, NH3 andudVFA concentrations, and rumen microbial protein of fistulated ongole cross bred.udThe research was conducted from October 05th to December 15th 2009 atudExperimental Unit, Faculty of Animal Science Gadjah Mada UniversityudYogyakarta. The research used three fistulated ongole cross bred cattles withudaverage body weight 289.3 ± 28.3 kg. The research used Latin Square Designudwith three treatments and three periods. Each treatments consisted of threeudreplications with one cattle each.udThe rations consisted of fermented rice straw (FRS), concentrate,udprotected soybean meal (SBM), fish meal (FM), palm kernel cake (PKC). Theudtreatments given were P1 = 40% (FRS) + 54% concentrate + 6% protected FM,udP2 = 40% (FRS) + 54% concentrate + 6% protected SBM, P3 = 40% (FRS) +ud54% concentrate + 6% protected PKC. Parameters that were observed were pH,udNH3 and VFA concentrations, and rumen microbial protein.udThe result showed that average from three treatments of P1, P2 and P3 forudpH 6.40; 6.17; 6.46, NH3 concentration 8.76; 13.30; 8.14 mg/100ml, VFAudconcentration 120.01; 115.61; 138.52 mmol and microbial protein 41.27; 42.98; ududududperpustakaan.uns.ac.idud ududududdigilib.uns.ac.idud ududududududud45.03 mg/100ml.
