- 1)HP, high plane; MP, medium plane; LP, low plane; Gr, grower; F, finisher; B, barrow; G, gilt; S, sex. Data are least squares means of 10 animals in each plane of nutrition × sex.
- 2)Provided with the MP and LP finisher diets during the finisher phases 1 and 2, respectively (see Table 1). The average ADFI during the phases 1 and 2 were 2.40 kg and 3.96 kg, respectively.
- 3)Provided with the LP finisher during both phases 1 and 2 (see Table 1). The average ADFI during the phases 1 and 2 for the pigs born from both groups of sires with the medium (see Table 4) and high weight gain potentials were 2.89 and 4.10 kg, respectively.
- 4)Average of backfat thickness measurements between the 11 and 12th ribs and at the last rib adjusted for a 115-kg liveweight.
