SEM, pooled standard error of mean.

¹⁾Significance level: NS, no significance;

^†p<0.10,

^*p<0.05.

²⁾E, environmental conditions (good sanitary vs poor sanitary); D, dietary treatments; E×D, interaction between environmental conditions and dietary treatments.

^a–eMeans in the same row with different superscripts differ in D (p<0.10).
