Effect of weaning age on cortisol release in piglets

Genetics and Molecular Research, 2016
The effect of weaning age on the adrenal cortex, which plays a vital role in the stress response, is currently unknown. Therefore, plasma adrenocorticotropic hormone (ACTH) and cortisol levels, weights and relative weights of adrenal glands, and steroidogenesis-related protein and enzyme expression levels in piglets weaned on different days were ...

Metabolomic insights for the authentication and traceability of antibiotic‐free pork: a pilot study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Antibiotic‐free production within the meat supply chain is a source of concern since new voluntary label claims need to be authenticated to prevent fraud. Therefore, an untargeted 1H NMR‐based metabolomics approach coupled to unsupervised (principal component analysis) and supervised (orthogonal partial least squares discriminant ...

Managemental influences on the selective proliferation of two strains of haemolytic Escherichia coli in weaned pigs [PDF]

, 1988
In an experimental study on a piggery it was found that haemolytic Escherichia coli of O-serotypes 138 or 139 proliferated in the intestinal tracts of pigs following weaning, with E.

Precision Feeding in Lactating Sows Improves Growth Performance and Carcass Quality of Their Progeny

Agriculture
The use of electronic sow feeders (ESFs) during lactation has been associated with weaning of heavier piglets when compared to traditional feeders, with a lower amount of sow feed per kg of weaned piglet, improved welfare of the sow, and no negative ...

Porcine circovirus 2 vaccination timing was not associated with piglets’ serological response

Veterinary Record, EarlyView.
Abstract Background The development of immunity in pigs starts in utero, but piglets are born immunologically immature and rely on maternal antibodies. Weaning exposes piglets to multiple stressors, yet vaccination is commonly performed around weaning.

Husbandry practices and gut health outcomes in weaned piglets: A review

Animal Nutrition, 2017
The immediate post-weaning period is one of the most stressful phases in a pig's life, and during this period, piglets are usually exposed to environmental, social and psychological stressors which have direct or indirect effects on gut health and ...

Facing Truths About Population Management

Zoo Biology, EarlyView.
Populations of wildlife, and domestic animals have large sinks for surplus animals. By contrast, zoos don't. Humans in industrialized societies are socialized with companion animals, i.e. surplus (i.e., typically denied reproduction) originating from unseen breeding cores.

Factors Influencing Reproductive Performance in Austrian Sow Farms Challenged by Reproductive Disorders

Veterinary Sciences
Many piglet-producing farms are facing poor reproductive performance, yet their characteristics remain poorly understood. This study aimed to identify factors contributing to reproductive disorders based on information easily identifiable through an oral

A 10-year trend in piglet pre-weaning mortality in breeding herds associated with sow herd size and number of piglets born alive

Porcine Health Management, 2021
Background Piglet pre-weaning mortality (PWM) is one of the biggest problems regarding sow performance and piglet welfare. Recently, PWM has increased in some countries, but it is not known if there are similar increases in other countries, nor whether ...

Adjusting Our Thinking About Feeding Animals: Fiber as the Metric for Mimicking Natural Diets

Zoo Biology, EarlyView.
A typical effect of the change of an animal group to a diet higher in fiber: juveniles keep growing, animals of ideal body weight maintain their weight, and obese individuals lose weight. ABSTRACT Free‐ranging animals often ingest markedly different diets than their counterparts under human care, whether companion animals, production animals, or zoo ...
