In the present study, nursery and growing pens were equipped with a solid floor (with no straw), an iron chain (as an enrichment), a stainless-steel vibratory feeder, and 3 to 4 bite drinkers to allow unrestricted access to feed and water. The stocking densities were about 0.64 and 1.28 m2 per pig for the nursery and growing pens, respectively. So, results of the present study clearly showed that keeping intact teeth and tail does not create more injury to the pigs if they are given appropriate enrichment and favorable environmental conditions.
