¹Data are expressed at least square means. Averages within row with different superscripts (a,b) differ significantly (P < 0.05) or tended (A,B) to differ (P < 0.10).

²In addition to the consumer class effect shown here, birth weight class affected (P < 0.05) all performance parameters except for ADG between days 19 to 28. Also foster parity class significantly (P < 0.05) affected BW at days 19, 28, 34, and 68, ADG between days 19 to 28, days 0 and 28, and days 28 to 68.
