Animal handling and welfare

David Fraser, Katherine E Koralesky, Geoff Urton
Animal protection law in Canada varies across the country. Federal animal protection law exists in the Criminal Code, in regulations for the transport of animals, and in regulations for humane handling and slaughter at abattoirs that are inspected by the Canadian Food Inspection Agency. Provincial animal protection laws often include provisions that i) describe a duty of care toward animals; ii) prohibit causing or permitting animal "distress;" iii) specify exemptions from prosecution; and iv) reference various national and other standards...

Increasing ethical concerns regarding animal experimentation have led to the development of various alternative methods based on the 3Rs (Refinement, Reduction, and Replacement), first described by Russell and Burch in 1959. Cosmetic and skin aging research are particularly susceptible to concerns related to animal testing. In addition to animal welfare reasons, there are scientific and economic reasons to reduce and avoid animal experiments. Importantly, animal experiments may not reflect findings in humans mainly because of the differences of architectures and immune responses between animal skin and human skin...

As the number of gestating sows reared in group housing increases, a better understanding of behavioral traits needed to negotiate these more complex social interactions promises to increase animal welfare and productivity. However, little is known about different behavioral strategies or coping styles in sows, and even less is understood about their ontogeny. To study the development of coping styles in adult gestating sows, 36 sows from the same sire line and same commercial maternal genetics were followed from birth through their second parity...

An expert opinion elicitation, based on a modified Delphi technique, was organized to collect the opinion of 16 Italian veterinarians with the aim of conducting a hazard and a welfare promoter characterization for defining and weighing a list of management and housing factors potentially associated with negative or positive welfare outcomes in dairy cows kept in loose housing systems. In addition, the 16 experts judged a set of animal-based measures in order to rate them by appropriateness and by the level of animal pain and suffering due to the welfare consequences they measure...

At all times prior to slaughter pigs may experience stress from a range of handling practices, such as fasting, loading and transport, mixing, and interaction with humans. These factors can affect the welfare of pigs, and carcass and meat quality both individually and collectively. Preslaughter stress is both an animal welfare and a meat quality issue. Behavioral and physiological studies have revealed that poor handling practices at the farm, during transport and at the slaughter plant have an adverse effect to pigs and may result in loss of profits due to animal losses during transport and in lairage...

Numerous studies have shown that providing straw to pigs can reduce undesirable behaviours such as aggression, tail biting and stereotypy. The measurement of various neuromodulators can be helpful in assessing the development of positive behaviours and overall animal welfare. The oxytocin release is frequently linked to positive emotions and positive welfare. It has been suggested that oxytocin modulates the serotoninergic system. This study aims to investigate the potential effect of straw provision in pigs on peripheral levels of oxytocin and serotonin...

There is no simple method to measure glomerular filtration rate (GFR) in swine, an established model for studying renal disease. We developed a protocol to measure GFR in conscious swine by using the plasma clearance of iohexol. We used two groups, test and validation, with eight animals each. Ten milliliters of iohexol (6.47 g) was injected into the marginal auricular vein and blood samples (3 mL) were collected from the orbital sinus at different points after injection. GFR was determined using two models: two-compartment (CL2: all samples) and one-compartment (CL1: the last six samples)...

There has been increased recognition of the 3Rs in laboratory animal management over the last decade, including improvements in animal handling and housing. For example, positive reinforcement is now more widely used to encourage primates to cooperate with husbandry procedures, and improved enclosure design allows housing in social groups with opportunity to escape and avoid other primates and humans. Both practices have become gold standards in captive primate care resulting in improved health and behavioural outcomes...

The development of effective drugs against fungal diseases involves performing infection experiments in animals to evaluate candidate therapeutic compounds. Cryptococcus neoformans is a pathogenic fungus that causes deep mycosis, resulting in respiratory illness and meningitis. Here we describe a silkworm system established to evaluate the safety and efficacy of therapeutic drugs against infection by Cryptococcus neoformans and the advantages of this system over other animal models. The silkworm assay system has two major advantages: 1) silkworms are less expensive to rear and their use is less problematic than that of mammals in terms of animal welfare, and 2) in vivo screenings for identifying candidate drugs can be easily performed using a large number of silkworms...

1. In commercial layer breeding, extensive gene pools are tested and selected for market requirements which must be anticipated at least 5 years ahead. Field results confirm a continuous positive genetic trend in egg output and better feed efficiency which can be converted into land savings. 2. Animal welfare and cage-free housing dominate future needs of the market. Nesting behaviour and minimal tendency to develop feather-pecking or cannibalism without beak treatment are key trait complexes. Stronger shells for longer production cycles without moulting have to be combined with better bones...

Involvement in canine and feline surgical neutering clinics is generally considered to be a key element of primary-care veterinary education, yet opportunities for veterinary students to develop their surgical skills with rabbit patients are uncommon. This is despite the fact that rabbits are currently estimated to be the third-most popular companion animal species and the fact that the British Small Animal Veterinary Association (BSAVA) recommends that all non-breeding rabbits be neutered soon after they attain sexual maturity...

Many veterinary and undergraduate equine science students have little previous horse handling experience and a poor understanding of horse behaviour; yet horses are one of the most unsafe animals with which veterinary students must work. It is essential for veterinary and equine students to learn how to interpret horse behaviour in order to understand demeanour and levels of arousal, and to optimise their own safety and the horses' welfare. The study utilised a qualitative research approach to investigate veterinary science and veterinary technology and undergraduate equine science students' interpretation of expressive behaviours shown by horses...

Handling and stunning at slaughter plants has greatly improved through the use of numerical scoring. The purpose of this paper is to encourage the use of numerical scoring systems at the slaughter plants to assess conditions that compromise welfare that occurred either during transport or on the farm. Some of the transport problems that can be assessed are bruises, death losses, and injured animals. Welfare issues that occurred on the farm that can be assessed at the abattoir are body condition, lameness, lesions, injuries, animal cleanliness and internal pathology...

Morbidity, mortality, and antimicrobial use and resistance are major concerns in the rearing of male dairy calves, so information to support disease prevention is important. The objective of this cross-sectional study was to describe management practices associated with the care of male calves during their first days of life on Canadian dairy farms. A survey was completed by dairy producers across Canada between March 1 and April 30, 2015. The survey included 192 questions covering producer background, farm characteristics, biosecurity practices, disease prevalence, calf health, animal welfare, lameness, milking hygiene, reproduction, and Internet and social media use...

Handling, weaning, and euthanasia are some of the most stressful practices performed on cow-calf operations. Although strategies to minimize stress exist, their use on western Canadian cow-calf operations is unknown. The objectives were to describe current stress-associated practices on western Canadian cow-calf operations, describe producer and operation demographics associated with the use of nonabrupt weaning methods, and explore producer perceptions toward these practices. A questionnaire focusing on stressful management practices was delivered to 109 cow-calf producers in western Canada...

Fish welfare is an important issue for growth of the aquaculture industry. Stress responses represent animal's natural reactions to challenging conditions and could be used as a welfare indicator. Cortisol level is relevant to fish welfare condition, and is a readily measured component of the primary stress response system. Generally, cortisol is measured by blood sampling. However, fish blood cortisol level could be instantly influenced by handling-stress at sampling. Fecal corticoid metabolites (FCM) are a mixture of several different metabolites with a wide range of polarities...

BACKGROUND: Slaughter reindeer are exposed to stress caused by gathering, handling, loading and unloading, and by conditions in vehicles during transport. These stress factors can lead to compromised welfare and trauma such as bruises or fractures, aspiration of rumen content, and abnormal odour in carcasses, and causing condemnations in meat inspection and lower meat quality. We investigated the statistical association of slaughter transport distance with these indices using meat inspection data from years 2004-2016, including inspection of 669,738 reindeer originating from Finnish reindeer herding areas...
