Abstract Farming externalities are believed to co-vary negatively, yet trade-offs have rarely been quantified systematically. Here we present data from UK and Brazilian pig production systems representative of most commercial across the world ranging ‘intensive’ indoor through extensive free range, Organic woodland explore co-variation among four major externality costs. We found that no specific farming type was consistently associated with good performance all domains. Generally, low land...

A survey to measure attitudes toward farm animal welfare was developed. We targeted science faculty because of their influence on production in the United States. initially interviewed 34 members from a large Midwestern public university assist with questionnaire development. After our written developed, we pilot-tested at this same university. Thereafter, sent an e-mail advance notice, first survey, and follow-up survey/thank-you national population members. With n = 446 (response rate...

ABSTRACTABSTRACTAnthropomorphism, attachment level, and belief in animal mind, as well owners' level of empathy attitudes toward their pets, are some the factors that affect human–animal interactions. Owners' ability to identify painful conditions pets may have important consequences for welfare these animals. In addition characterizing typical Norwegian dog owner, aim this work was study relationship between empathy, attitudes, perceived pain. A sample 3,413 owners Norway received an...

The aim of this study was to develop and evaluate a machine vision algorithm assess the pain level in horses, using an automatic computational classifier based on Horse Grimace Scale (HGS) trained by learning method. use is dependent human observer, who most time does not have availability animal for long periods must also be well order apply evaluation system correctly. In addition, even with adequate training, presence unknown person near can result behavioral changes, making more complex....

An enzyme-linked immunosorbent assay has been developed for the direct of cortisol in saliva man, sheep, calf and pig. The is sensitive (integral 1pg), highly specific reproducible, advantage over radioimmunoassay being cheaper quicker to carry out. relatively-non invasive method collecting on cotton buds coupled with simple equipment provide a good potential assessing status studies stress welfare farm animals as well possibility monitoring mammals generally.

Boars housed in commercial conditions are often pens or individual crates, and subjected to low-stimulus environments, which may affect the expression of normal species-specific behaviors compromise its health welfare. Breeding boars’ has been poorly reported scientific literature, as well their physiology circadian rhythm cortisol. Moreover, an environmental enrichment for breeding boars, far we know, not studied lacking impact on how it can improve Thus, aimed evaluate behavior salivary...

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 emphasis (VCF) and science (ANS). The was conducted via e-mail. E-mail addresses were gathered from 58 departments 27 websites. Our respondents consisted of 446 ANS 157 VCF. In general, VCF had more empathetic welfare than did ANS. Both expressed greater comfort the current production systems...

Aggressive interactions, and their consequences, are the most important causes of poor welfare in piglets. behaviour can be modulated by prenatal neonatal environment several species. Commercially kept pregnant sows often subjected to food restriction, which compromise welfare. Limited information is available on consequences sow hunger during pregnancy outcomes for High fibre diets mitigate feeling and, consequently, it may improve productivity measures. The aim this study was assess...

AbstractCats are popular companion animals, particularly in Europe and North America, appear correspondingly large numbers animal shelters. Temperament tests not widely used to assess cats before adoption from However, exhibit a wide range of temperaments as do the families adopting them ensuring compatibility between two could increase rate successful placement. Scores on feline temperament profile (FTP), which measures cat's responses standardized interactions with an unfamiliar person,...

Summary The aim of the present study was to obtain information on possible mechanisms underlying cribbing behaviour in horses. To investigate horse's responsiveness an external stimulus, a device for telemetric measurement thermal threshold, using forelimb withdrawal reflex, developed and validated. Measurements threshold took place horses (n = 11) before during periods. Heart rate monitored continuously same Blood samples were collected periods as well age‐ sex‐matched control 11)....

To examine attitudes toward farm animal welfare among veterinary college faculty.E-mail survey.157 US faculty with large or food emphasis.Veterinarians from 27 colleges were contacted via e-mail and asked to complete a 7-page survey relating issues. Thirty-one percent of those responded.71% respondents self-characterized their attitude as "we can use animals for the greater human good but have an obligation provide majority animals' physiologic behavioral needs." An additional 19% more...

Associations between stress hormones and preterm delivery have not been fully explored. In this study, pregnant women enrolled from 52 clinics in 5 Michigan communities (1998-2004) provided urine samples for 3 days (waking bedtime) during midpregnancy. Urinary catecholamine levels (epinephrine, norepinephrine, dopamine) were measured a subcohort (247 760 term deliveries), 3-day median value was calculated. Polytomous logistic regression models assessed relations quartiles (of the median)...
