  1. The Theoretical Application and Comparison of the Olfactory Sensory Organs in Swine vs Canines for Accelerant and Explosives Detection

    Swine may be able to work alongside scent detection canines, or replace them completely, in the scent detection field. Miniature pigs are the focus of this study since their larger counterparts can cause damage to potential evidence and to the scene itself. Ignitable Liquid Residues (ILRs) are...

  2. Texas 4-H Swine Project Guide

    This guide for 4-H members explains how to select a good animal, build proper facilities, manage an animal's feeding and nutritional requirements, and take care of health concerns. There is also information on training and showing a pig.

  3. A Comparison of Three Animal Welfare Assessment Programs on Canadian Swine Farms

    Standard measures used in animal welfare assessments include animal-based measures obtained by observing animals, resource-based measures obtained by observing facilities, and management-based measures obtained by interviewing farmers and checking records. Animal welfare assessments are composed...

  4. Gene-edited 'micropigs' to be sold as pets at Chinese institute

  5. Configuring the authentic value of real food : farm-to-fork, snout-to-tail, and local food movements

  6. Stakeholder attitudes toward farm animal welfare

    We developed a survey to measure attitudes toward farm animal welfare, then targeted two US groups considered highly influential in this area: veterinary college faculty members with large animal/food animal emphasis (VCF) and animal science faculty members (ANS). The survey was conducted via...

  7. Genetic analysis of the individual pig behaviour in backtests and human approach tests

    The most recent development in pig production has focused increasingly on the well-being of the individual pig and animal-friendly housing conditions, i.e. the launch of the group housing of sows in the EU. In this regard, however, standard procedures which may be stressful to the animals and...

  8. Evidence of multiple virulence subtypes in nosocomial and community-associated MRSA genotypes in companion animals from the upper midwestern and northeastern United States

  9. Phylogenetic analysis of 626 hepatitis E virus (HEV) isolates from humans and animals in China (1986-2011) showing genotype diversity and zoonotic transmission

  10. If you knew what was good for you! The value of environmental enrichments with known welfare benefits is not demonstrated by sows using operant techniques

    This study assessed the motivation of gestating sows housed in standard, barren gestation stalls (used for breeding/implantation and/or gestation) for access to environmental enrichment. Enrichment consisted of a cotton rope or rubber mat in comparison to positive (additional food when fed at...

  11. Increasing the frequency of co-mingling piglets during the lactation period alters the development of social behavior before and after weaning

    The purpose of this study was to determine how increasing the frequency of co-mingling affected piglets' behavior development before and after weaning. Co-mingling once (CM1), piglets interacted with 1 unfamiliar litter Days 10-18 after birth; co-mingling twice (CM2), piglets interacted with 1...

  12. Scientists' assessment of the impact of housing and management on animal welfare

    A total of 22 scientists contributed to a consensus-oriented conceptual framework for assessment of farm animal welfare, addressing priority issues in cattle, pigs, and chickens. They used the Delphi method, in which participants contributed anonymously through e-mail. The framework puts welfare...

  13. Feeder use patterns in group-housed pregnant sows fed with an unprotected electronic sow feeder (Fitmix)

    Previous studies on feeder use in group-housed pregnant sows focused on dynamic groups and protected electronic sow feeders (ESF). This study observed 60 pregnant sows, 1st to 8th parity - housed from Day 29 of pregnancy to 1 week before parturition in stable groups of 20 animals, 1 Fitmix...

  14. Using data collected for production or economic purposes to research production animal welfare: an epidemiological approach

    Epidemiologists use the analyses of large data sets collected for production or economic purposes to research production nonhuman animal welfare issues in the commercial setting. This approach is particularly useful if the welfare issue is rare or hard to reproduce. However, to ensure the...

  15. Differences in open field behavior between heterozygous and homozygous negative gilts for the RYR(1) gene

    A test widely used to assess fear and novelty responses in domestic species is the open field. The aim of this study was to investigate the effect of RYR(1) genotype on open field behavior in growing pigs. The study subjected 15 heterozygous (Nn) and 15 RYR(1)-free (NN) gilts of 19 weeks of age...

  16. The effect of environmental manipulation on behavior, salivary cortisol, and growth of piglets weaned at 14 days of age

    Environmental enrichment can be a useful tool to reduce belly nosing behaviors in early weaned piglets. The aim of this study was to assess the effect of environmental enrichment on behavior, salivary cortisol, and productivity of piglets weaned at 14 days of age. The study assigned 112 piglets...

  17. Production costs and animal welfare for four stylized hog production systems

    Nonhuman animal welfare is arguably the most contentious issue facing the hog industry. Animal advocacy groups influence the regulation of hog farms and induce some consumers to demand more humane pork products. Hog producers are understandably reluctant to improve animal well being unless the...

  18. Do domestic pigs in controlled environments contrafreeload?

    Many experiments report that animals will work (lever press) for food in the presence of freely available identical food. This phenomenon has attracted the attention of applied ethologists because it seems to prove that animals have a need to express appetitive behaviour. If this is the case,...

  19. Aggressive behavior in two different group-housing systems for pregnant sows

    The study housed 120 pregnant sows from Day 29 of pregnancy to 1 week before parturition either in groups of 10 with trickle feeding (TRICKLE) or in groups of 20 with an unprotected electronic sow feeding (FITMIX). The study recorded aggressive interaction on 11 nonconsecutive days. Frequency of...
