A total of 27 litters of \u201cDuroc boars \u00d7 Landrace \u00d7 Large White\u201d piglets were selected and randomly divided into three groups. Those groups were the conventional weaning group (C), the odorant spray group (S), and the weaning-after-mixing group (M), with three repeats in each group and three litters in each repeat. The experiment began seven days before weaning, and ended seven days after weaning. The piglets were euthanized on the eighth day after weaning, and the jejunum and ileum tissues and contents were sampled. The pH and enzyme activities of the intestinal contents were determined, and the intestinal morphologies were revealed using H&amp;E staining. It was concluded that a 2% glutaraldehyde spray on the body surfaces of piglets after weaning could increase average weight after nursery, lower intestinal pH, increase the activities of digestive enzymes, improve intestinal morphology, and relieve weaning stress. It was also found that weaning after mixing could increase the average weight after nursery, lower intestinal pH, improve intestinal morphology, and reduce weaning stress.<\/jats:p>","DOI":"10.3390\/ani12172200","type":"journal-article","created":{"date-parts":[[2022,8,28]],"date-time":"2022-08-28T21:22:56Z","timestamp":1661721776000},"page":"2200","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Effects of Weaning Modes on the Intestinal pH, Activity of Digestive Enzymes, and Intestinal Morphology of Piglets"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7122-6523","authenticated-orcid":false,"given":"Zhifang","family":"Shi","sequence":"first","affiliation":[{"name":"College of Animal Science and Technology, Henan University of Animal Husbandry and Economy, Zhengzhou 450046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0277-3707","authenticated-orcid":false,"given":"Tianwu","family":"Wang","sequence":"additional","affiliation":[{"name":"Faculty of Animal Science and Technology, Yunnan Agricultural University, Kunming 650210, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingjing","family":"Kang","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Henan University of Animal Husbandry and Economy, Zhengzhou 450046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yidan","family":"Li","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Jilin Agricultural University, Changchun 130118, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Li","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Henan University of Animal Husbandry and Economy, Zhengzhou 450046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Xi","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Henan University of Animal Husbandry and Economy, Zhengzhou 450046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105044","DOI":"10.1016\/j.applanim.2020.105044","article-title":"Pre-weaning socialization and environmental enrichment affect life-long response to regrouping in commercially-reared pigs","volume":"229","author":"Heng","year":"2020","journal-title":"Appl.
