Table 4.
Average daily weight gain (ADWG; g/piglet/d; mean ± SEM), average daily feed intake (ADFI; g/piglet/d; mean ± SEM), feed conversion rate (FCR; kg feed/kg weight gain; mean ± SEM) in phase 1 (0–15 dpw), phase 2 (16–27 dpw), phase 3 (28–49 dpw) and overall (0–49 dpw). Piglets in the Control group were fed a standard diet, whereas piglets in the Enzyme treated group were fed an adapted diet with more soybean meal in phase 1 and 2, and a decreased level of 65 kcal/kg net energy in phase 3. No significant differences (P > 0.05) between groups were observed
