* Administration route of each product that were delivered according to manufacturer labeled dosages; SC = subcutaneous, PO = pour-on. † Block(s) that each product was administered to. Each block consisted of two side-by-side pens of cattle of the same sex, source, and arrival date, that were randomly allocated one of the two pens, and pens were randomly assigned to treatment (PT or META); thus, each block represents a single treatment replication. Blocks 1 to 5 were in the Nebraska feedlot; blocks 6 to 8 were in the Kansas feedlot. Blocks 1, 3, and 6 were steers; blocks 2, 4, 5, 7, and 8 were heifers. ‡ Draxxin, Zoetis Animal Health, Parsippany, NJ, USA; administered only to the META treatment pen within each block. § Zoetis Animal Health, Parsippany, NJ, USA. ⸙ Merck Animal Health, De Soto, KS. ⸕ Boehringer Ingelheim, St. Joseph, MO, USA. ‖ Newport Laboratories, Inc., Worthington, MN, USA. ⸎ Elanco Animal Health, Greenfield, IN. ⸘ MWI Animal Health, Boise, ID, USA.
