AN SC 201: Animal Science

University Park

Article Comparision

You'll be looking for two articles that have something in common so that you can compare them but they will not be on exactly the same topic.  

For example, one article might be on the effects of vitamin E on immune function in pigs, the second article might be on the effects of vitamin E on immune function in fish.

Reminder: You must use two articles, each about one specific experiment. 
“Review articles” summarizing several experiments are not acceptable for this assignment. 
You also need to make sure the articles are within the dates specified in the assignment.
