This is the fourth in a series of peer-reviewed practice tip articles, each including two or three fact sheets on feed additives for swine.

Acidifiers (v17n5) Anthelmintics (dewormers) (v17n6) Antibiotics (v17n5) Carbohydrate-degrading enzymes and proteases (v17n6) Carcass modifiers (v17n6) Flavors (v18n1)

High dietary levels of copper and zinc for growing pigs (v18n2) Mold inhibitors, mycotoxin binders, and antioxidants (v18n1) Phytase (v18n2) Phytogenic feed additives (phytobiotics-botanicals) Probiotics and prebiotics

Previous practice tips have been published in issues of the Journal of Swine Health and Production as linked above; those published in this issue are shown in bold face. Future fact-sheet topics will include probiotics and prebiotics and phytogenic feed additives (phytobiotics or botanicals).
