研究了与筑巢母猪生物学相关的环境刺激对哺乳和哺乳行为以及仔猪生长的影响。底板类型（海滩砂v .混凝土）和基质类型（秸秆喂入器v .无秸秆饲喂）进行2 × 2析因试验，每个重复9头经产母猪。从产前1周至产后13 ~ 15天，母猪单独饲养在7·6 m2的有棚猪圈中。在产后第0、3、6和12天对母猪和仔猪的行为进行24小时的视频记录。对于有经验的母猪（胎次4至5），从分娩终止到可感知的排奶的潜伏期往往比在水泥地板上更短（1207（s.e. 109)最小;数量= 7 v . 1725（s.e.）123)F2，8 = 3·93，Pv. 1666（s.e.）132)F2，8 = 3·56，Pv.混凝土地板（384（s.e.）20)v . 327（s.e.）16)第3天，F1，19 = 5·6，Pv. 318（s.e.）13)第6天; F1，21 = 9·09; Pv.不带吸管给料器（385（s.e. 20)v . 326（s.e.）18)第3天，F1，19 = 5·11，Pv. 323（s.e.）13)F1，21 = 6.21; P11，8 = 3.58; 7（s.e.）1）、5（s.e. 1)和6（s.e.）1)前腿划水每小时分别）。在实验围栏中停留期间，在沙子上饲养的仔猪的生长速率往往高于在混凝土地板上饲养的仔猪（261（s.e.）33)v . 240（s.e. 30)g/头/日; F1.25 = 3.38; P本实验结果表明，提供生物学相关刺激影响母猪和仔猪的哺乳行为。哺乳终止的减少、前腿划动的频率减少、哺乳持续时间的增加以及哺乳行为的早期发育可能有利于仔猪的早期采食。
The influence of environmental stimuli considered biologically relevant for nest building sows, on nursing and suckling behaviour and piglet growth was investigated. Effects of floor type (beach sand v . concrete) and substrate type (straw feeder v . no straw feeder) were examined in a 2 × 2 factorial experiment with nine replicates of four multiparous sows. The sows were kept individually in roofed 7·6 m 2 ‘get-aw ay-pens’ from 1 week pre-partum until 13 to 15 days post-partum . The behaviour of sows and piglets were video recorded for 24 h on days 0, 3, 6 and 12 post-partum . The latency from termination of farrowing until perceptible milk ejection tended to be shorter for experienced sows (parity 4 to 5) kept on sand than on concrete floors (1207 (s.e. 109) min; no. = 7 v . 1725 (s.e. 123) min; no. = 6, respectively; F 2,8 = 3·93, P v . 1666 (s.e. 132) min; no. = 5, respectively; F 2,8 = 3·56, P v . concrete floors (384 (s.e. 20) v . 327 (s.e. 16) s on day 3; F 1,19 = 5·6, P v . 318 (s.e. 13) on day 6; F 1,21 = 9·09; P v . without straw feeder (385 (s.e. 20) v . 326 (s.e. 18) s on day 3; F 1,19 = 5·11, P v . 323 (s.e. 13) on day 6; F 1,21 = 6·21; P 11,8 = 3·58, P P v . 7 (s.e. 1), 5 (s.e. 1) and 6 (s.e. 1) foreleg rowings per h, respectively). During the stay in the experimental pens, the growth rate of piglets kept on sand tended to be higher than for piglets kept on concrete floors (261 (s.e. 33) v . 240 (s.e. 30) g per piglet per day; F 1,25 = 3·38; P The results of the present experiment indicate that provision of biologically relevant stimuli affect the nursing and suckling behaviour of sows and piglets. The reduced termination of sucklings, the reduced frequency of foreleg rowing, the increased duration of suckling as well as the earlier development of suckling behaviour might have been advantageous for the early milk intake of the piglets.
