Alfalfa hay, dehydrated alfalfa meal and alfalfa press-cake could be used as supplements to corn stover. Alfalfa press-cake is a by-product of Pro-Xan1, a leaf protein concentrate extracted from green-chopped alfalfa. Pro-Can contains the high protein and xanthophyll fraction desirable in poultry rations. According to Enochian2, xanthophyll from Pro-Xan is utilized 1.7 times more efficiently in poultry rations than xanthophyll from dehydrated alfalfa. If the high fiber, press-cake by-product of the Pro-Xan process can be utilized in ruminants as efficiently as dehydrated alfalfa, the press-cake may be a suitable substitute for the dehydrated alfalfa. The objective of this study was to conduct a feeding trial where each of the alfalfa products was compared in rations containing stover silage and ground stover stacks for wintering beef cattle. These studies were then complimented with two digestion-nitrogen valance trials.
