Abstract
Galiang Corm Meal is one nutrient-dense feed ingredient that is a potential partial substitute for corn. Corn contains 4.38% crude protein, 2.61% crude fiber, 1.25% ether extract, 4.68% minerals & 8.08% moisture while GCM may be better than corn since both were used together to formulate feed; hen flock bands had larger final body weights (1.565 kg) and were heavier than their counterparts receiving only corn weight gain (1.518 kg) at the end of the feeding trial. Statistically significant was revealed more feed consumed by birds compared to others with the lowest amount of feed needed/kg gain for birds that received GCM at 50% inclusion level. GCM added between 25%-75% levels resulted in growth performance, feed usage efficiency & carcass yield of broilers that were fed both products compared to commercial rations. Economically GCM available at a 50% substitution level provided the highest gross margin/bird making this level of dietary inclusion the best cost-benefit ratio of the dietary treatments evaluated.
