31.2.2 Statistics Analysis

Analysis of variance (ANOVA) was performed on the means to determine whether
there were significant ( p < 0.05) differences among the groups. When ANOVA indi-
cated statistical significance, the Duncan's multiple comparisons test was used to
determine which means were significantly different. SAS package (version 9.12,
Institute Inc., Cary, NC, USA) was used for all statistical analyses. Results are
expressed as means ± SD. Values were reported as significant have p -values < 0.05.

31.3 Results and Discussion

31.3.1 Weight Gain, Food Intake, and Food Ef fi ciency Ratio

Tables 31.2 and 31.3 show the weight at beginning, weight at sacrifice, weight
gain, food intake, and FER of rats fed on experimental diets. Body weight gain and
food intake of rats fed the experimental diets did not differ from those of rats fed
the control. This finding is in agreement with what Sugiyama and coworkers
(Sugiyama et al. 1989 ) reported that taurine supplementation had no influence on
