Mette S Herskin, Bodil H Nielsen
Across the international dairy industry, the vast majority of dairy herds have dehorned cows. Farmers choose to dehorn calves for different reasons such as easier handling of non-horned cattle and reduced risk of injuries in animals and staff. This review focuses on disbudding by use of hot-iron cautery as is practiced by dairy farmers in calves <3 months of age. We examine welfare effects of the use of NSAIDs in combination with a local anesthetic including indicators relevant for the three major welfare concerns-affective states, basic health, and functioning as well as the possibility to behave naturally...

Background/aims Tail docking neonatal piglets remains a controversial animal welfare issue. Although banned in the UK, it is widely practiced in many countries as a safeguard against tail biting among pigs reared in intensive systems. Concerns exist whether tail docking can induce chronic pain in later life. This preliminary study examined the effects of partial tail amputation on activating transcription factor 3 (ATF3), a marker of peripheral nerve injury and regeneration and NMDA-glutamate receptor NR2B subunit which participates in the mediation of chronic pain...

Background Adverse experiences in early life, such as exposure to stress, can have long term detrimental effects on the future physiology and behaviour of the animal. Typically animals exposed to such experiences are more anxious and more reactive to stress in later life. Tail biting is a major problem in modern pig production, both in terms of animal welfare and productivity. Tail docking in early postnatal life is common practice to reduce risk of this problem, but causes pain and may alter pain sensitivity...

Previous studies have shown that the interaction between limiting vitamin A (VA) and an alcohol dehydrogenase 1 C (ADH1C) variant in beef cattle results in increased intramuscular fat in the longissimus thoracis muscle in one genotype when fed low dietary VA. Although quality grade is important for increased profitability and improving taste characteristics of beef products, limiting VA too drastically can impair animal welfare. The objectives of this study were to determine if this marker-assisted management strategy would be effective, and whether any impairment in immune function would occur in a feedlot setting...

Various forms of overcrowding are common in heifer-rearing operations. Our objectives for this study were to evaluate the effects of overstocking at the feedbunk (100, 133, 160, or 200% of capacity) on the growth performance, feedbunk sorting behaviors, and hygiene of 128 gravid Holstein heifers (475 ± 55.3 kg) consuming an alfalfa haylage and corn silage diet diluted with processed wheat straw at an inclusion rate of 25.2% (DM basis). In this study, heifers were overstocked only at the feedbunk, and not with respect to available freestalls or pen area...

The objectives of this cross-sectional study were to describe housing and management practices on farms using automatic milking systems (AMS) in 2 states of the upper Midwest and to evaluate the association of various housing and management factors with 3 measures of animal welfare: prevalence of lameness, severe hock lesions, and dirty cows. Fifty-four farms were visited once to collect facility measurements and observations, interview the dairy producer, and score cows for locomotion, hock lesions, and hygiene...

A major public health issue, Toxoplasma gondii infection can affect humans mainly via the consumption of animal products from certain species, including small ruminants. Therefore, a regular monitoring of the infection in ovine and caprine populations is advisable for the control of human and animal toxoplasmosis. Antibody detection in individual and bulk tank milk may represent a valid alternative to serological analysis, being its collection easy and not affecting animal welfare. Many serological tools for milk analysis have already been validated for several parasites, including Apicomplexa...

We surveyed professionals from the Chilean Ministry of Agriculture working with small-scale farmers to characterize the attacks of free-ranging dogs across Chile. Nationwide, in a single year, free-ranging dogs attacked 25% of the ca. 8500 farms included in the survey, killing or injuring about 10 000 small ruminants. These dogs were ranked as the main cause of animal losses for small-scale farmers, representing a threat to the livelihoods of this vulnerable group. Further, free-ranging dogs attacking small ruminants were considered as human-subsidized, since they would be recruited by irresponsible ownership and abandonment from urban centers...

  Animal welfare, conservation, and stress assessment are all critical components of species survival. As organisms experience stressors, they accumulate physiologic dysregulation, leading to multiple negative health outcomes. This brief review suggests measuring the degree of stress-induced damage, known as allostatic load, and then using allostatic load to evaluate changes implemented to improve animal welfare and conservation efforts. Over the past two decades, human clinical research has developed multiple allostatic load indices constructed from composites of neuroendocrine, cardiovascular, metabolic, and immune biomarkers...

  Pituitary pars intermedia dysfunction (PPID), also known as equine Cushing's disease, is widely reported in middle-aged to older domestic equids but to date reported in only one nondomestic equid, the onager ( Equus hemionus onager). This case series reports clinical, hematological, and pathological findings consistent with PPID in two further equid species: one Chapman's zebra ( Equus quagga chapmani) and five Przewalski's horses ( Equus ferus przewalskii). The case series reports basal adrenocorticotropic hormone (ACTH) testing as a method to diagnose and monitor PPID in zoological equids and the use of pergolide mesylate to reduce basal ACTH concentration and reduce clinical signs associated with PPID...

Organic agriculture (OA) is considered a strategy to make agriculture more sustainable. Bhutan has embraced the ambitious goal of becoming the world's first 100% organic nation. By analysing recent on-farm data in Bhutan, we found organic crop yields on average to be 24% lower than conventional yields. Based on these yield gaps, we assess the effects of the 100% organic conversion policy by employing an economy-wide computable general equilibrium (CGE) model with detailed representation of Bhutan's agricultural sector incorporating agroecological zones, crop nutrients, and field operations...

Developing a common market and allowing free movement of goods, services, and people is one of the main objectives of the European Union (EU) and the European Free Trade Area. In the field of scientific research, Directive 2010/63/EU on the protection of animals used for scientific purposes aims to improve the welfare of laboratory animals by following the principle of the 3Rs (replacement, reduction, and refinement). Each breeder, supplier, and user must appoint a designated veterinarian to advise on the well-being and treatment of the animals...

The genome revolution represents a complete change on our view of biological systems. The quantitative determination of changes in all major molecular components of the living cells, the "omics" approach, opened whole new fields for all health sciences. Genomics, transcriptomics, proteomics, metabolomics, and others, together with appropriate prediction and modeling tools, will mark the future of developmental toxicity assessment both for wildlife and humans. This is especially true for disciplines, like teratology, which rely on studies in model organisms, as studies at lower levels of organization are difficult to implement...

Blood analysis has recently become a popular tool to assess the welfare of the wild cats. However, the estimates of blood parameters may depend on the sampling method. We have tested (1) if the sampling procedure influences blood parameters and (2) what parameters are the most efficient in assessing the physiological status in wild cat species. We assessed the effect of handling time on red blood cells (RBC) and white blood cells (WBC) counts, the ratio of neutrophils to lymphocytes (N/L ratio), and serum cortisol level within 1 hr after the capture of the animal in six far-east wild cats (Prionailurus bengalensis euptilura)...

Animal welfare is an increasingly global initiative, which makes the intricate business of operating across borders of particular relevance to the movement. There is, however, a distinct absence of literature dedicated to investigating operational strategies that are more likely to result in the success of international animal welfare initiatives. In addition to this, opportunities exist to investigate the human aspects of animal welfare, parallel to the growing field of animal-based science. This study aimed to begin addressing these gaps by conducting semi structured interviews with 15 leaders of some of the largest international animal welfare charities...

Feline relocation is used increasingly in animal welfare to decrease shelter euthanasia rates and increase positive outcomes. Concerns about infectious disease introduction and transmission are often expressed; however, little research has been conducted on even the baseline prevalence of infectious disease following relocation. This study, which collected data on 430 cats relocated through an established program over 7 months, evaluated the prevalence of upper respiratory infection (URI), feline panleukopenia virus (FPV) and dermatophytosis at one destination agency...
