a Weight, average daily gain and initial body measurements, with the exception of initial weight, were all tested using weight as a covariate. Intermediate and final body measurements were tested using the value of that measurement at the initiation of the experiment as a covariate.

b In each row, SE ( for conventional oat means) and P-value refer to standard error of a mean and the probability of a treatment effect. One filly in the hull-less oat treatment died during the study. Number of fillies completing the study were 10 and 9 for the conventional and hull-less oat treatments, respectively.
