Welfare Effects of the Use of a Combination of Local Anesthesia and NSAID for Disbudding Analgesia in Dairy Calves—Reviewed Across Different Welfare Concerns

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 […]

Post-natal development of EEG responses to noxious stimulation in pigs (Sus scrofa) aged 1–15 days

This study examined electroencephalographic (EEG) indices of acute nociception in pigs (Sus scrofa) aged 1, 5, 7, 10, 12 and 15 days, post-natal. Ten pigs per age were anaesthetised with halothane in oxygen and maintained at a light plane of anaesthesia. EEG was recorded bilaterally using a five-electrode montage. Following a 10-min baseline period, tails […]

Current issues in fish welfare

Human beings may affect the welfare of fish through fisheries, aquaculture and a number of other activities. There is no agreement on just how to weigh the concern for welfare of fish against the human interests involved, but ethical frameworks exist that suggest how this might be approached. Different definitions of animal welfare focus on […]

Science-based assessment of animal welfare: farm animals

Animal welfare is to do with the feelings experienced by animals: the absence of strong negative feelings, usually called suffering, and (probably) the presence of positive feelings, usually called pleasure. In any assessment of welfare, it is these feelings that should be assessed. Because feelings are subjective, they cannot be investigated directly. However, there are […]

Using aversion learning techniques to assess the mental state, suffering, and welfare of farm animals

The extent that handling farm animals causes them to suffer is a central concern when assessing their welfare. “Suffering” is a mental state, resulting from different emotions, such as fear, pain, or boredom, which have different causes and effects on the animal’s behavior and physiology. What is common is that they are aversive; animals will […]

Evaluation of intramuscular ketoprofen and butorphanol as analgesics in chain dogfish (Scyliorhinus retifer)

Abstract 10.1002/zoo.20105.abs The mediation of nociception with analgesic medications has not been well documented in elasmobranchs. The purpose of this study was to determine effective analgesic doses of the opioid agonist-antagonist, butorphanol, and the non-steroidal anti-inflammatory drug, ketoprofen, in an elasmobranch. This was evaluated by repetitively assessing minimum anesthetic concentrations of the immersion anesthetic, tricaine […]

Welfare of animals: Behavior as a basis for decisions

Behavioral measures are of particular value in welfare assessment; some behaviors such as stereotypies, lack of or normal responsiveness, and excessive aggression being direct indicators of poor welfare. They are especially important when the welfare problems are of long duration. In addition, the behavior of animals is also needed to interpret other welfare measures such […]

Animal welfare defined in terms of attempts to cope with the environment


Effect of noxious stimulation upon antipredator responses and dominance status in rainbow trout

A potentially painful experience may modify normal behavioural responses. To gauge the importance of pain relative to predation or social status, we presented competing stimuli, a predator cue or an unfamiliar social group, to two groups of noxiously treated rainbow trout, Oncorhynchus mykiss. In the predator cue experiment, fish were classified as bold or shy. […]
