Notes: 1With the exception of Weight gain, which was measured between days 11 and 17, all measures were taken at the end of the experiment on day 17. 2For Weight gain, pH, pCO2, Na+ and Glucose the test was a two-sample t-test; for Heart, Liver and Spleen, the test was an ANCOVA with weight on day 17 included as the covariate. *Indicates a P-value ≤ 0.006.
