Influence of Wheat Variety upon in vitro and in vivo Lactate Levels1

Larry W. Varner2 and Walter Woods3

University of Nebraska, Lincoln 68503

Abstract

Two in vitro and two in vivo fermentation studies were conducted to compare the fermentation characteristics of different wheat (Triticum vulgare) varieties to corn. Feed intake was reduced and rumen lactate concentration increased when corn was replaced by wheat in the ration. Scout 66 wheat supported the highest rumen lactate concentration and lowest feed intake as compared to corn. Gage wheat or Trapper wheat. The in vitro fermentation studies indicated that wheat was more digestible and supported a higher lactate concentration than corn. However, different varieties of hard red winter wheat varied markedly in the level of lactate produced in vitro. Generally, Scout 66, Turkey and Warrior wheat supported the highest in vitro lactate concentration and Gage wheat the lowest among the wheat varieties studied.
