The aim of this study was to investigate the influence of ad libitum access to compound feeds rich in fibre (ante partum (a.p.) and peri partum) on the DM intake, body mass development and performance of sows as well as excretion of () via sows' faeces. From day 109 (d-7) of gestation, 25 of 48 sows (23 considered as control) received access to one of two different high-fibre pellets from d-7 until the second day post partum (p.p.) (d2) (fibre groups (FG) 1 and 2) in additional to a lactation diet. The additional DM intake of the high-fibre pellets a.p. was 2.13 ± 1.15 kg in FG 1 and 3.14 ± 0.68 kg in FG 2. This led to higher DM intake in the first lactation week and significantly lower losses of weight and back fat thickness during lactation. The bacterial counts of in sows' faeces directly p.p. were 10 times lower in FG 1 and 100 times lower in FG 2 compared to the controls. High amounts of fibre led to higher DM intake throughout lactation, which had beneficial effects on sows' body conditions. It seems that high fibre intake influenced the excretion of at parturition, which could improve the health of newborns.
本研究的目的是调查自由采食富含纤维的复合饲料（产前和围产期）对母猪干物质摄入量、体重发育和生产性能以及母猪粪便中（）排泄的影响。从妊娠第109天（d-7）开始，48头母猪中的25头（23头作为对照）从d-7开始直至产后第二天（d2）可自由采食两种不同的高纤维颗粒饲料之一（纤维组（FG）1和2），同时提供泌乳日粮。产前高纤维颗粒饲料的额外干物质摄入量在纤维组1中为2.13±1.15千克，在纤维组2中为3.14±0.68千克。这导致第一泌乳周的干物质摄入量更高，且泌乳期间体重和背部脂肪厚度的损失显著更低。与对照组相比，产后母猪粪便中的细菌计数在纤维组1中低10倍，在纤维组2中低100倍。高纤维含量导致整个泌乳期的干物质摄入量更高，这对母猪的身体状况有有益影响。高纤维摄入量似乎影响了分娩时（）的排泄，这可能改善新生仔猪的健康状况。
