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

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 508-523, July 2026.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

Addition of oat hulls to an extruded rice-based diet for weaner pigs ameliorates the incidence of diarrhoea and reduces indices of protein fermentation in the gastrointestinal tract

, 2008
An experiment was conducted to determine whether adding oat hulls to weaner pig diets based on extruded rice or unprocessed wheat influenced post-weaning diarrhoea (PWD) and protein fermentation in the large intestine.

Experimental induction of Escherichia coli diarrhoea in weaned piglets

, 2012
Escherichia coli diarrhoea is a multifactorial condition which usually occurs during the post-weaning and is responsible for economic losses in pig production.

Unravelling the Genetic Mechanisms of Litter Traits in a Maternal Line of Pigs

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 560-580, July 2026.
ABSTRACT Reproductive traits related to litter size are the main indicators of reproductive efficiency in pig production and are continuously evaluated for the selection of maternal lines. Several environmental and genetic factors are involved with the development of these traits.

The gut microbial metabolite indole-3-aldehyde alleviates impaired intestinal development by promoting intestinal stem cell expansion in weaned piglets

Journal of Animal Science and Biotechnology
Background Weaning stress-induced diarrhea is widely recognized as being associated with gut microbiota dysbiosis. However, it has been challenging to clarify which specific intestinal microbiota and their metabolites play a crucial role in the ...

Integrated Metabolomics and Gut Microbiota Analysis Reveal the Intestinal Stress Response of Juvenile Four‐Finger Threadfin (Eleutheronema tetradactylum) to Nitrite Exposure

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
Nitrite exposure induces intestinal stress in juvenile Eleutheronema tetradactylum, characterized by microbial dysbiosis, metabolic reprogramming, and altered digestive enzyme activities. Integrated metabolomics and microbiota analyses reveal coordinated hostmicrobe responses involving key pathways such as ABC transporters and amino acid metabolism ...

Investigation of the Relationship Between Ovine Selection Signature DIS3 Like 3′‐5′ Exoribonuclease 2 (DIS3L2) Gene and Weaning Weight and Average Daily Gain Until Weaning in Lambs

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT The growing demand for animal products, combined with declining livestock production due to urbanization and climate change, underscores the need for sustainable breeding strategies. In sheep production, liveweight and weight gain until weaning are key economic traits.

The effect of santicipatory behaviours, generated by Pavlovian conditioning, on the development of play in early and normally weaned rats.

, 2009
Since the classic studies of Pavlov, a wide variety of researchers have investigated the process of classical conditioning and used it to investigate animal behaviour.
