Creep feed provision may ease weaning, hence we determined the impact of providing fibrous creep feed before weaning and adding this feed to the post-weaning diet on piglet behavior and performance. Pre-weaning, litters with on average 12 piglets were given creep feed (CF, n = 12 litters) or not (NF, n = 10 litters). Post-weaning, piglets (n = 8 pens with 4 piglets/treatment) were given a weaner diet (CON) or weaner diet supplemented with creep feed (CS). Behaviors were scored in the home pen at d11, 16, 22 and 27 after birth and at wk 1 and 2 post-weaning. Feed intake, growth and fecal consistency were measured up to d14 post-weaning. A blood sample was taken at d2, 15 and 29 after birth and d2, 5 and 14 post-weaning. CF-piglets consumed on average 397 ± 71 g creep feed before weaning. CF-piglets grew faster in the last week before weaning than NF-piglets (249 ± 7 vs. 236 ± 11 g/d, F_{(1, 18)} = 5.81, P = 0.03). However, CF- and NF-piglets did not differ in weaning weight, within-litter coefficient of variation in weaning weight, behaviors in the farrowing and weaner pen, and haptoglobin concentrations. Creep feed supplementation enhanced feed exploration at wk 2 post-weaning (0.29 ± 0.08 vs. 0.11 ± 0.03%, F_{(1, 27)} = 5.27, P = 0.03), but did not affect other post-weaning behaviors. Pre-weaning creep feed provision and post-weaning creep feed supplementation did not affect overall feed intake, growth, feed efficiency and fecal consistency for the first 14 days post-weaning, neither body weight at d14 post-weaning. Nevertheless, CF-piglets had a lower within-pen coefficient of variation in body weight at d14 post-weaning than NF-piglets (13.6 ± 1.9 vs. 15.1 ± 1.5%, F_{(1, 26)} = 6.89, P = 0.01). In conclusion, pre-weaning creep feed provision and post-weaning creep feed supplementation had no clear effects on piglet behavior and performance.

蠕变饲料的供应可能使断奶变得容易，因此我们确定了在断奶前提供纤维性蠕变饲料并将这种饲料添加到断奶后饮食中对仔猪行为和性能的影响。断奶前对平均12头仔猪的仔猪进行creep饲（CF，ñ = 12升）（否，NF， ñ= 10磅）。断奶后，仔猪（ñ= 8只猪，每只4只仔猪）接受断奶仔猪日粮（CON）或补充了蠕动饲料的断奶仔猪日粮（CS）。在出生后第11、16、22和27天以及断奶后第1周和第2周在家庭围栏中对行为进行评分。断奶后至第14天测量饲料摄入量，生长和粪便稠度。出生后第2、15和29天以及断奶后第2、5和14天采集血样。断奶前CF仔猪平均消耗397±71 g蠕动饲料。断奶前的最后一周，CF仔猪比NF仔猪生长更快（249±7比236±11 g / d，F_（ 1，18 _） = 5.81，P= 0.03）。但是，CF和NF仔猪的断奶体重，断奶体重的窝内变异系数，产仔和断奶仔猪的行为以及触珠蛋白浓度没有差异。蠕变饲料补充剂在断奶后第2周增强了饲料勘探效率（0.29±0.08 vs. 0.11±0.03％，F_（ 1，27 _） = 5.27，P= 0.03），但不影响其他断奶后行为。断奶前14天断奶前提供的蠕动饲料和断奶后补充蠕动饲料不会影响总体饲料的采食量，生长，饲料效率和粪便稠度，断奶后第14天的体重也没有影响。尽管如此，断奶后第14天CF仔猪的体重内变异系数低于NF仔猪（13.6±1.9对15.1±1.5％，F_（ 1，26 _） = 6.89，P= 0.01）。总之，断奶前的we饲和断奶后的creep饲对仔猪的行为和性能没有明显的影响。
