The height of the villi and depth of the crypts in the small intestine were studied after weaning in pigs reared under various circumstances in the Netherlands. Pigs taken from herds with a long history of postweaning diarrhoea had in general significantly shorter villi and deeper crypts than their counterparts from a specific pathogen-free herd. Weaning was associated with villus shortening, crypt deepening and subsequent villus lengthening in pigs from the specific pathogen-free herd. Giving supplementary feed during the sucking period was beneficial in preventing shortening of the villi and this villus shortening was less severe when the crypts were deep at weaning, a condition that perhaps lessens the severity of postweaning diarrhoea.
在荷兰，对处于不同饲养环境下的断奶仔猪小肠绒毛高度和隐窝深度进行了研究。来自有长期断奶后腹泻病史猪群的仔猪，其绒毛通常明显比来自无特定病原体猪群的仔猪短，隐窝更深。断奶与无特定病原体猪群仔猪的绒毛缩短、隐窝加深以及随后的绒毛延长有关。在哺乳期提供补充饲料有利于防止绒毛缩短，当断奶时隐窝较深时，这种绒毛缩短不太严重，这种情况可能会减轻断奶后腹泻的严重程度。
