We investigated the effect of offering supplementary dietary fibres to suckling piglets on their behaviour and performance before weaning. From 5 to 22 days of age, suckling piglets were offered a high-fibre diet (HF; 5% cellulose; n=5 litters), or a control low-fibre diet (n=5 litters). Piglets were housed with the sows in individual farrowing pens, and had access to maternal milk until weaning, at 23 days of age. Behaviours of six focal piglets per pen were scored at 6, 16 and 21 days of age. All piglets were individually weighed at 5, 15 and 20 days of age and feed intake was measured daily at the pen level. Piglets on the HF diet were more active than controls (P=0.05), and spent more time suckling or massaging the udder (P=0.01) and interacting with pen mates (P=0.008). Time spent manipulating pen mates, which may reflect re-directed foraging activity in the absence of substrate, accounted for most of the time spent interacting with pen mates (⩾73% of total time spent interacting). Dietary fibres had no effect on BW and feed intake. In conclusion, inclusion of cellulose in the supplemental diet of suckling piglets affects behaviour, with no deleterious effects on performance before weaning.
我们研究了在哺乳仔猪断奶前提供补充膳食纤维对其行为和性能的影响。从 5 到 22 日龄，哺乳仔猪提供高纤维饮食（HF；5％纤维素；n=5 窝）或对照低纤维饮食（n=5 窝）。仔猪与母猪一起在单独的分娩栏中饲养，并且可以在 23 日龄断奶前食用母乳。在 6、16 和 21 日龄时，每窝有 6 只仔猪的行为进行评分。所有仔猪在 5、15 和 20 日龄时单独称重，在栏级水平上每天测量饲料摄入量。与对照组相比，HF 饮食组的仔猪更活跃（P=0.05），并且花费更多时间吮吸或按摩乳房（P=0.01）和与同窝仔猪互动（P=0.008）。与同窝仔猪互动的时间中，花费在操纵同窝仔猪上的时间最多，可能反映了在没有基质的情况下重新定向的觅食活动（占与同窝仔猪互动的总时间的 ⩾73％）。膳食纤维对 BW 和采食量没有影响。总之，在哺乳仔猪的补充饮食中添加纤维素会影响行为，而在断奶前对性能没有不利影响。
