Although good for animal welfare, ad libitum feeding practice could  cause environmental problems

A paper published in Animal Feed Science and Technology suggests that while a group of pregnant sows fed ad libitum corn silage appeared quieter and more content, the ad libitum diet resulted in 1.6 times more waste slurry. This not only reduced the cleanliness of the animal pens — thereby posing another challenge to animal welfare — but could also require additional thought on how to manage the increased waste from hog farms, according to Peter Ebertz, the lead author and Ph.D. candidate at the University of Bonn.
