摘要：
A comparison of weight at 63 days, growth rate and feed efficiency has been carried out along three seasons on four selected lines (two dam lines selected for litter site at weaning and two sire lines, currently selected for postweaning daily gain). Sire lines (Line R (2598 g) and Line C (2251)) were heavier than dam lines at 63 days (Line V (2116 g) and Line P (2086 g)). The growth rate was also higher on the lines selected for (Line R (52.0 g/d) and Line C (45.8 g/d)) than on the lines selected for reproductive traits (Line P (41.4 g/d) and Line V (41.0 g/d)). Postweaning feed efficiency of Line R (2.71) was the best. However, no differences were found between Lines V (2.84) and C (2.91). Line P had the largest value (3.15).
