Comparative Feeding Values of Whole-Shelled or Whole Steam-Rolled Corn

Summary

Four Holtein dry cows were ued to cl the feeding value nitrogen and energy utilization of whole-shelled or whole team-rolled corn and whole-shelled or whole steam-rolled barley All cows were fed control diet and 4 treatment dieh consecutinly in tIlt order of I Jltalian ryegrass only (IRG)

2) IRG + whole-shelled corn (WCI 3) lRG + hole steam-rolled corn (RC) 4) lRG + whole-shelled barley (WB) and 5) JRG + whole steam-rolled barley (RB) for 2 eeks per treatment They were ofshyfered to meet approximately IOO7c of total digestible nutrients (TDN) requirements according to Japanese Feeding Standard for dairy cattle ( ]994) The ratio of 1 RG to grain of 4 diets was 64 The reshysults ere as follows I) The nutrient digestibilities of RC and RB diets were higher than those of we and WB diets respectiely except for crude fiber acid detergent fiber and neutral detergent fiber 2) The dry matter digestibilitie of corn and harley estimated by the difference method were 69 and 49S- in whole-shelled type compared with 83( and 83or in the other type respectively Similarly the starch digestibilities of corn and barley wcre 73c and 489lt in whole-shelled type compared with 100or and IOOc in the other type respectively 3) The nitrogen retention in RC and RB diets tended to inshycrease with the decreae in fecal nitrogen loss 4) The digestibility and metabolizability of energy in corn and barley were markedly increased by steam-rolled procesing_ The extent of increase was greater in barley than that of corn 5) The TDN digestibie energy (DE) and metabolizable energy (ME)
