没有吃小麦或在槽中喂养的经验的美利奴断奶仔猪被用来研究他们对新情况的行为反应以及他们学会吃小麦的速度。两组8只羊放牧的牧场上，单独圈养，并在槽中喂养15分钟/天，20天。第一组每天都吃小麦，而第二组在前12天吃干草，然后在接下来的8天吃小麦。第1组中的所有绵羊开始吃小麦需要14天，但第2组中的6只在第一次提供小麦后2天吃小麦。结果表明，绵羊学习吃小麦可能有三个阶段。看来羊必须克服对槽和小麦的恐惧。最后，他们必须学会理解、咀嚼和吞咽小麦。
Merino weaners with no prior experience of eating wheat or of feeding in troughs were used to study their behavioural responses to novel situations and to the speed with which they learned to eat wheat. Two groups of 8 sheep grazing on pasture were individually penned and fed in troughs for 15 min/day for 20 days. Group 1 was given wheat every day, while Group 2 received hay for the first 12 days and then wheat for the next 8 days. It took 14 days for all sheep in Group 1 to begin eating wheat, but 6 of Group 2 ate wheat 2 days after it was first offered. The results suggest there may be 3 phases in sheep learning to eat wheat. It seems that sheep must overcome fear of the trough and of the wheat. Finally, they must learn to prehend, chew and swallow wheat.
