If your Mom made peanut butter stuffed celery for you when you were a kid, this doesn't seem like such a strange idea. Here are some situations that might seem strange, but actually have perfectly reasonable origins. Consider the following:

Straw Suits Some Cows!
      In a study designed to investigate ways to reduce winter feeding costs, researchers fed cattle ammoniated straw. During the 3-year trial, 32 cows - 5 to 8 years of age - were fed straw from December to May . Some cows performed poorly, while others maintained themselves on the diet. Why did some cows perform so poorly?

Moose Migrate Uphill!
      Contrary to the general pattern of migration, a population of moose in central Norway migrate from low-lying summer areas to high-elevation winter areas. Archeological evidence shows they have done this for thousands of years even though they are heading to poor quailty winter range. Why do these moose migrate up hill?

Cows Don't Eat Grass!
      To reduce the high cost of feeding lactating dairy cows in confinement, many producers are using intensively managed pastures as a source of low-cost, high-quality forage. However, dairy cows reared in confinement perform poorly on pasture. Upset, perplexed producers report that cows don't eat grass and milk production plummets. What's going on?
