¹Con: Basal diet (without mineral supplementation)
²IM: Basal diet + inorganic minerals supplementation
³OM: Basal diet + organic minerals supplementation
⁴HOM: Basal diet + higher organic minerals supplementation
⁵Standard error of means
⁶P value obtained from the mixed procedure of SAS with temperature effect (B), mineral effect (M), and interaction effect between temperature and minerals (T × M). A P value less than 0.05 indicates that the results are statistically significant
