Table 9. Effects of dietary sorbent minerals on body weight gain, feed conversion ratio, mortality, and lesion score in Cobb/Cobb broilers following subclinical E. maxima/C. perfringens co-infection (Trial 2).

Body weight gain, feed conversion ratio (feed intake/weight gain), and mortality were determined between days 0 and 14 after E. maxima infection (days 14 and 28 post-hatch), and/or between days -14 and 14 after E. maxima infection (days 0 and 28 post-hatch). Each value represent the mean weight gain, feed conversion ratio, or % mortality±SEM (n=20). Intestinal lesion scores were determined at day 1 following final C. perfringens infection (day 22 post-hatch) on a scale from 0 to 3. Each value represent the mean lesion score±SEM (n=8). Within each column, values with different superscripts are statistically different according to the Duncan's multiple range test (P<0.05). ^# See Table 4 for treatment group. Values in boxes are significantly different compared with the co-infected NE group given the unsupplemented diet (p<0.05).
