Improvement Nutrient Digestibility and Production Performance of Cattle Through Restricted Amino Acid and Organic Minerals Addition on Fermented Palm Oil Waste-Based Feed
Abstrak: The objective of this
research was to evaluate the effect of branched-chain amino acid and organic
mineral addition on fermented palm oil waste based-feed to the nutrients
digestibility and cattle performance. The research was done using nine Ongole
crossbred cattle by applying randomized block design with three treatments and
three replications. The first treatment (R0) was fermented palm oil waste-based
feed; and the second treatment (R1) was R0 with 13% cassava leaves addition;
and the third treatment (R2) was R1 with organic minerals (40 ppm Zn; 10 ppm
Cu; 0.1 ppm Se; and 0.3 ppm Cr) addition. The result showed that R2 gave a
significant effect (P<0.05) on crude protein, crude fiber, and ether extract
digestibility, but showed no significant effect on dry matter and organic
matter digestibility and cattle production parameters. The research concluded
that fermented palm oil waste-based feed with 13% cassava leaves and organic
minerals addition gave the best result based on the digestibility and cattle production
parameters.
