High milk production -> litter gain
•对母猪饲料的高效利用
High utilization of the sow feed
•高窝产仔猪数和高分娩率
High litter size and farrowing rate

IMPORTANT TOPICS
妊娠母猪的饲喂FEEDING OF GESTATING SOWS -体况的管理MANAGEMENT OF BODY CONDITION ●目前的饲喂曲线Correct feed curves
●在妊娠后期每头母猪每天饲喂超过3.5公斤就饲喂太多了
More than 3.5 kg pr sow/day in late gestation is too much
●饲喂低于2.2-2.3公斤，就不能满足维持需要
Less than 2.2-2.3 kg is below the requirement for maintenance
●每头母猪达到正确的饲喂曲线需要通过体况管理来获得
The right feed curve for each sow is obtained through management of body condition
●测量背膘
Backfat measurement
●将背膘测量的结果和体况评分进行比较
Result of backfat measurement compared with palpation
●分娩时的背膘在16-18毫米
