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.

Increasing the viscosity of the intestinal contents stimulates proliferation of enterotoxigenic Escherichia coli and Brachyspira pilosicoli in weaner pigs [PDF]

, 2002
The present study was designed to evaluate the effect of increased viscosity of the intestinal digesta on proliferation of enterotoxigenic Escherichia coli and the intestinal spirochaete Brachyspira pilosicoli in weaned pigs.

Effect of split-weaning in first and second parity sows on sow and piglet performance.

, 1997
The effect of split-weaning (SW) on: weaning to oestrus interval (WOI), sow reproductive performance, piglet growth and body weight and backfat development, was studied in 319 first and second parity sows.

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 ...

Effects of Precision Feeding on Economic and Productive Yields of Hyperprolific Lactating Sows Allocated at Different Farrowing Pens

Animals
The results obtained using precision feeding in maternities (electronic sow feeders, ESFs) may be affected by the type of farrowing pen, as the design of the pen may modify the behavior of the sows.

Integrated Multi‐Omics Analysis Reveals the Genetic Basis of Phenotypic Variation in Tibetan Sheep

Integrative Zoology, EarlyView.
SNaPshot‐validated GWAS results demonstrated significant correlations between candidate single nucleotide polymorphisms (SNPs) and body size traits in Tibetan sheep. Concurrently, hematoxylin and eosin staining, alongside muscle fiber analysis, confirmed pronounced morphological differences in muscle tissue between sheep of varying conformation.

Plasma Cortisol and Behaviour in Early Weaned Piglets

Acta Veterinaria Scandinavica, 1980
Comparisons were made of Cortisol concentration and behavioural activity between piglets weaned at 3 weeks of age (early weaned piglets), and piglets weaned at 8 weeks of age (control piglets). Early weaned littermates were placed in cages with a floor area of either 0.20 m2 per piglet or 0.15 m2 per piglet.

The Company We Keep: Effects of Different Social Environments on Male Guinea Pig Behaviour and Hormones Over the Course of the Ontogeny

Ethology, EarlyView.
To examine how their behaviour and hormones change over different life phases, male guinea pigs experienced two different social environments from juvenility to adulthood. Only one environment contained social stimulation by unfamiliar conspecifics. Although no differences in testosterone and cortisol concentrations were found, it was interesting that ...

From Social Experience to Social Behaviour: Hormonal and Behavioural Phenotypes During Adolescence in Male Guinea Pigs

Ethology, EarlyView.
To investigate how different social environments during adolescence influence hormones and behaviour, adolescent male guinea pigs were pair‐housed with a female either with or without additional social stimulation through repeated brief encounters with unfamiliar conspecifics.

Correlation between reproductive performance and sow body weight change during gestation

Journal of Animal Science and Technology
This study investigated the correlation between piglet performance and sow body weight change (BWC) during two gestational periods: 35–70, 70–105, and 35–105 days.
