In parentheses in each column is the number of lambs (n). (BW): birth live weight; (DWGW-150): average daily live weight gain from weaning to 150 days of age; (hd): Hampshire Down; (ile): Ile de France; (suf): Suffolk; (tex): Texel. (½): means half-blood of the described breeds. Different lowercase letters in the lines indicate differences in BW or DWGW-150 between pregnancy types in the same breed. Different capital letters in the columns refer to differences in BW or DWGW-150 among different breeds for the same type of pregnancy, according to Tukey or Bonferroni test (p < 0.05).
