断奶窝重（Weaning litter weight）仔免生后4周龄或6周龄断奶时称测的全窝仔免总重量（包括寄养的仔免在内）。
结果表明，60日龄仔猪数、20日龄窝重和初生窝重，是影响断奶窝重的重要因素。
Results show that 60—day litter size, 20—day litter weight and litter weight at birth are important factors influencing weaning weight of litter.
然而，大窝不仅带来出生仔猪和断奶仔猪体重较轻的问题，而且同窝内仔猪初生重和断奶重的变异更大。
However, large litters bring problems, with lighter piglets born and weaned, and greater within-litter variation in piglet birth and weaning weight.
