- Line effect indicates significant (+/−) or non significant (=) differences between the Epi+ and Epi− lines (p < 0.05, see Additional file 2: Table S1). Phenotypes were measured at slaughter (27 weeks of age) except for body weight at 3 weeks and behavioral traits (see “Methods”). Methylation levels were measured by LUMA on blood sampled at 23 weeks of age
- * p-values from the linear mixed model analysis were adjusted with the Benjamini–Hochberg correction
-
aThese traits were measured in females only (since in the original HSR line and in the Epi− and Epi+ lines, abdominal fat is nearly absent in males)
