- W85936346 abstract "Utilization of palm kernel cake (PKC) as the principal feed for ruminantswas investigated in four studies. The study on the nutritive value showed thatPKC·solvent extracted (PKC·S) and PKC·expeller pressed (PKC·E) containedsimilar amounts of OM, CP, CF and ADL. PKC·E had higher OM. EE and GEbut lower NFE, NDF. ADF and shell contents. Amounts of Ca. P. Cu and Znwere similar in both types ofPKC, but Na was higher and Mg was lower in PKCS.Ruminal pH. NH3-N concentration. molar proportions of YF A and passagerates of liquid and small digesta particles in cattle fed either PKC·S or PKC·Ewere similar. Total YF A concentration was higher in cattle fed PKC·S. EffectiveOM and OM degradabilities were lower in animals fed PKC-S. but degradatIOn rates were similar. PKC-E contained more soluble fractions than PKC-S. CP ofPKC-S was more soluble. but its effective degradability and degradation ratewere similar to that of PKC-E.The study on the effects of formaldehyde treatments on CP degradabilityof both types of PKC showed that CP degradability decreased with increasinglevels of formaldehyde. Acid-pepsin digestibility showed no difference in CPdigestibility among untreated and formaldehyde-treated PKC up to 2.5g/l OOg CP.The study on the effects of PKC and formaldehyde treatment on theperformance and nutrient utilization of cattle showed that feed intake was lowerin cattle fed PKC-E, but growth rates and feed per gain ratios did not differ fromthose fed PKC-S. Formaldehyde-treated (2g/100g CP) PKC gave poorer growthrates and feed conversion ratios when compared to untreated PKC. Types of PKCand formaldehyde treatment did not affect the nutrient digestibility. but PKC-Egave lower N retention. Formaldehyde had no effect on N retention.In the final study, lambs fed PKC + 15% grass showed improvement inintakes and growth rates. Urea at either 0.5 or 1.0%. had no effect on feed intakesand feed conversion ratios. However. growth rates of lambs fed PKC + 0.5% ureawere higher compared to other groups. Lambs fed PKC plus 15% grass and 0.5%urea had the highest intake and growth rate. Carcass traits were not affected byurea but grass supplementation reduced dressing percent and kidney fat of lambs" @default.
