一群努力推动中国养猪业发展的仁人志士共同打造的大型线上培训系列节目—猪学社上线，以期与养猪人共度时艰！前言 Foreword 丹育猪以高产著名于世，但由于猪场建设、饲养管理等诸多方面的挑战，让丹育猪在中国的生产性能未能达到预期，但丹育种猪在中国养猪业的受青睐程度仍越来越高。猪译馆特收集整理了一系列丹育相关资料，目前正在转载当时丹麦养猪研究中心制作的丹育《妊娠管理指南》，敬请关注。编者的话 Editor's Note 对妊娠母猪的正确管理有助于提高和维持母猪高产、稳产。顺便推荐给学习专业英语的爱好者，这是不可多得的学习资料。这也是一份做猪场操作标准流程SOP的很好的资料。妊娠母猪主要根据体况进行饲喂Pregnant Sows Should Primarily Be Fed By Body Condition.转入妊娠舍时，要评估母猪的体况且按照合适的饲喂曲线进行饲喂 By insertion in the gestation unit, the body condition is assessed and the sows are placed on the right feed curve. 1、用于肥胖母猪的饲喂曲线。 Feed curve for: Fat sows. 2、用于体况中等母猪的饲喂曲线。 Feed curve for: Average sows. 3、用于瘦的母猪的饲喂曲线。 Feed curve for: Skinny sows. 4、用于后备母猪的饲喂曲线。 Feed curve for: Gilts. 
一、在以下几个时间点再次对母猪的体况进行评估： The body condition is assessed again at: Day 60 in the middle of the gestation.二、如有需要，可改变其饲喂曲线进行饲喂。 And feed allocation is adjusted to another feed curve if necessary. （一）在冬季，由于温度较低饲喂曲线均要上调 In the winter period the feed curves are adjusted upwards due to lower temperature. 1、肥胖的母猪更容易发生难产，因此更需要助产。 Fat sows are more likely to have farrowing problems and hence greater need for farrowing assistance. 2、肥胖的母猪易有多发性骨折，因此有更高的死淘率。Fat sows have multiple fractures and thereby higher mortality rates.Fat sows eat less in the farrowing unit than sowsin normal body condition.The maintenance feed for fat sows isgreat.5、体况不一的母猪的总饲料消耗量多于体况均衡的母猪（约100FU/窝Sows that vary in body condition have a greater total feed consumption than sows with a stable body condition (approx. 100FU/litter).Skinny sows have a greater risk of shoulder wounds, leg problems and returning.
补充说明-妊娠母猪的饲喂Additional Comments – Feeding Of Pregnant Sows研究表明配种后的前四周内给予瘦的母猪3.8个饲料单位/天的饲料对窝产仔数有积极的影响。但对初产母猪而言，这四周内按照这种饲喂强度将会造成负面影响。如果想要初产母猪增重，必须要在怀孕四周后增加饲喂量。Studies has shown a positive e?ect on litter size with skinny sows by a high feed strength of 3,8 FU per day in the ?rst 4 weeks after mating. In gilts there is a negative e?ect of high feed strength in these 4 weeks. If you want a weight gain in gilts it must therefore be after 4 weeks of gestation.由于母猪能量缺乏会导致流产，所以母猪哺乳失重需要尽快得以恢复Apossibleweightlossfromthefarrowingunitshould as soon as possible be obtained, since sows in negative energy balance may abort.胎儿直到妊娠期的最后几周内生长速度才达到最快。因此，这时的饲喂强度要从3.5上升到4.0个饲料单位/天，但这不适用于肥胖母猪。The fetuses have by far the largest growth in the last weeks of gestation. Therefore the feed strength should be increased in this period from 3,5 to 4,0 FU per day however not for fat sows.母猪在第四胎后身体才发育完全，因此年轻的母猪要补充额外的饲料。在配种单上记录母猪的体况有利于监测母猪体况的变化和发展。
The sows are not fully grown until after fourth litter, therefore young sows should have extra feed. The sows’ body condition can advantageously be noted in the mating list, so it is possible to monitor the body conditions development.任何圈舍都适合所有的饲喂曲线进行饲喂，如在地板上直接投料或在长料槽中投喂液态料，对配种群进行分类，分别转入不同圈，每个圈再选择适合的饲喂曲线。All feed curves can be used in any type of pen. By ?oor feeding or wet feeding in a long through, there can be used as many feed curves as there are pens for a mating group.
配种后四周内后备母猪的饲料量以体重不增加为宜。明显超过维持量的饲喂将会增加胚胎着床时的损失。建议体重较小的后备母猪每天饲喂2.2 个饲料单位，体重较大的后备母猪每天饲喂2.4 个饲料单位。It is recommended that gilts are fed without a large weight gain in the ?rst 4 weeks after mating. Feeding signi?cantly above maintenance leads to increased fetal loss during implantation. Therefore should small gilts be fed about 2,2 FU per day and large gilts about 2,4 FU per day.Feeding by body condition to achieve the desired weight at farrowing. 不是所有的母猪都有一致的饲料转化率。特别是那些分娩后非常瘦的母猪，即使给予额外的饲料， 也很难再次达到正常的体况。因此必须评估母猪的体况，且调整太肥和太瘦母猪的饲喂量。要获得高的饲料转化率，好的体况管理是关键。Not all sows have the same feed conversion. Especially sows that are very emaciated from the farrowing unit can be hard to get at a normal body condition again, even if they are given extra feed. Therefore the sows’ body conditions must be checked and skinny and fat sows feed strength is regulated. Good body condition management is critical for the feed consumption when the sows have a high feed consumption per kg gain.温度对母猪的饲料采食具有重要的影响。此外，瘦的母猪脂肪层较薄，需要采食更多的饲料来产热。Temperature has a great in?uence on the sows feed need. Furthermore, skinny sows have a lower layer of fat and therefore a greater need for feed to heat production.温度下降，导致每天需要的额外饲料量。饲料单位 / 天：Extra feed by decreasing temperature FU/day:
