Revamping porcine enrichment

Pigs may exhibit stereotypic behaviors due to lack of proper mental stimulation. Stereotypic behaviors include self-inflicted wounds, biting at the pen, polydipsia, cage destruction, and loud vocalizations. These behaviors may be alleviated with proper daily enriching stimulation. Pigs enjoy a...

Conscious urine sampling and quantification from indwelling catheterization of female Yucatan swine

In addition to routine diagnostic testing of urine for health status, data from urine collection is often necessary to support various nutritional, metabolic, biochemical, and physiologic studies. Collection methods can be stressful to the animal (manual restraint), may require sedation...

Development of edible environmental enrichment objects for weaned pigs

Studies on environmental enrichment for weaned pigs have predominantly focused on stimulating exploration through “nonedible toys.” The research on edible enrichment objects is very limited. For this reason, the aim of this study was to develop and characterize edible environmental...

Multiple refinements to the anaesthetic protocol for laparoscopic orthotopic kidney auto-transplantation in a pig model

Fifty-four pigs (Sus scrofa, Large White cross) from a commercial pig farm were anaesthetised over a six-year period from October 2011. The procedural stages included initial instrumentation for intra-operative monitoring, laparoscopic nephrectomy, preparation of the kidney graft, orthotopic auto-transplantation by...

The effect of needle-free administration of local anesthetic on the behavior and physiology of castrated pigs

Pigs are routinely castrated in many countries without giving pain relief, which is an animal welfare concern. The objectives of this study were to evaluate the stress caused by administering local anesthetic (LA) using a needle-free injection system and evaluate...

Agricultural animals as biomedical models: Occupational health and safety considerations

The use of agricultural animals in biomedical research is increasing. Their overall size and metabolic rate, organ size, longer gestation period, and other physiological similarities make them good candidates for animal models of human disease. There are a number of...

Pen enrichment and sex interaction on growth performance and metabolite concentrations of autochthonous Windsnyer pigs kept in a high stocking density

The objective of the study was to determine the interaction of pen enrichment and sex on growth performance and blood metabolite concentrations of Windsnyer pigs. Forty-eight growing Windsnyer pigs of both sexes, with an average initial body weight of 21.6...

Executing specific foraging behaviours does not represent a general goal state of foraging in dry sows (Sus scrofa)

Intensively housed domestic pigs (Sus scrofa) have little opportunity to perform diverse foraging behaviour though they still seem strongly motivated to do so. Here, we investigated whether the execution of specific behaviours may in itself satisfy their foraging motivation. We...

Environmentally enriched pigs have transcriptional profiles consistent with neuroprotective effects and reduced microglial activity
