Weaning piglets as a model for studying pathophysiology of diarrhea

Veterinary Quarterly, 1998
During fifty years weaning age of piglets decreased from, in former days, ten to twelve weeks till, nowadays, three to five weeks. Early weaned piglets frequently have diarrhea. When piglets had diarrhea after weaning, enterotoxigenic E.coli (ETEC) or rotavirus were generally detected in the faeces; however, they were also detected in faeces of piglets

Early‐life environmental enrichment reduces anxiety and induces sex‐dependent neuroplasticity in hypothalamic oxytocin and vasopressin neurons

Journal of Neuroendocrinology, Volume 38, Issue 9, September 2026.
The experimental design and key findings of the study. Mice were exposed to a Perinatal enriched environment (PEE) or a Non‐enriched environment (NE) from the prenatal period through weaning (PND21). Behavioural assessments were conducted in adulthood (PND60), including the elevated plus maze, sociability test, light/dark box, sociability test and ...

Effects of Algae β‐Glucan Supplementation on the Performance and Intestinal Immune System of Healthy Weaned Piglets

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 642-654, September 2026.
ABSTRACT While β‐glucans from plants and yeasts have been extensively studied in weaned piglets, studies examining algae β‐glucans are scarce. Thus, the present study aimed to examine the effects of feeding algae β‐glucan in weaned piglets. Male, 21‐day‐old, weaned crossbred piglets were allotted to three experimental groups, which were fed either an ...
