¹Provided with the nursery phases 1, 2 and 3 diets for 7, 14 and 12 days, respectively.
²Provided with the nursery phases 2 and 3 diets for 14 and 19 days, respectively.
³Provided with the nursery phases 2 and 3 diets and the high-plane grow-finish phase 1 diet for 7, 14 and 12 days, respectively.
^1-3See Table 1 for nutritional values of the diets used in each feeding program. Data are means or least squares means ± SEM of two pens consisting of 34 females and 34 castrated males, respectively.
⁴SEM, standard error of mean; BW, body weight; ADG, average daily gain; ADFI, average daily feed intake; D, day.
⁵Initial BW was included in the model as a covariate.
^a,bMeans with no common superscripts differ (p <0.05).
