*Values based on average after 48 h of digestion.

^†RB = annual ryegrass baleage harvested in the boot-to-early dough stage; CS = corn silage harvested in the milk stage; BH = Tifton 85 bermudagrass hay harvested on a 4-wk frequency from May to June 2015; 50:50 = 50% mixture of soybean hulls and 50% corn gluten feed, respectively; CC:CSM = 85% mixture of cracked corn and 15% mixture of cottonseed meal, respectively.

^a,b,c,dWithin a row, means without common superscripts differ P < 0.10.
