The Effect of an Exercise Paddock on Dairy Cow Behavior, Health, and Nutrient Digestion during the Transition from Pregnancy to Lactation.

Providing an exercise paddock may improve the behavior and health of cows in their dry period. We compared a control group of cows in a shed with no exercise paddock and an experimental group in the same shed but with access to an exercise paddock. Both groups had ad libitum total mixed ration (TMR) indoors combined with access to a paddock (Group EX).

Improving hen welfare on cage-free egg farms in Asia: Egg producers' perspectives.

There is a trend towards the adoption of cage-free housing systems in the egg industry across Asia. While cage-free housing systems can hold significant animal welfare advantages over cages, there can also be challenges in managing these systems. This exploratory study aimed to investigate the perspectives of egg producers on the main challenges and proposed solutions associated with cage-free systems in China, Indonesia, Thailand, Japan, Malaysia, and the Philippines.

The Effects of Preslaughter Electrical Stunning on Serum Cortisol and Meat Quality Parameters of a Slow-Growing Chinese Chicken Breed.

Electrical stunning is widely utilized prior to a neck cut to induce unconsciousness in order to improve animal welfare and slaughter efficiency in the broiler production industry. However, slaughter without stunning is still very commonly used in China, in part because there is a belief that stunning reduces meat quality. The purpose of this study was to determine whether the physical (hemorrhages, pH, drip loss, and shear force) and chemical (inosinic monophosphate concentration and reducing sugar content) properties of broiler meat differed between chickens in preslaughter stunning and nonstunned slaughter groups, and whether the groups differed in their levels of cortisol as an indicator of stress.

Greyhound morbidity and mortality in Australia: A descriptive analysis of reported data from regulatory racing agencies.

Commercial greyhound racing is legal in Australia but controversial due to concerns around animal welfare. To make evidence-based recommendations of animal welfare standards, a comprehensive analysis of available data on race events, animal health, injuries and fatalities is required. We undertook a review of publicly available data and reports published by official greyhound racing bodies for the purpose of determining how morbidity and mortality events associated with dog training and racing could be benchmarked.

The Relationship between Animal Welfare and Farm Profitability in Cage and Free-Range Housing Systems for Laying Hens in China.

Several countries and regions have regulations in place to provide standards for the welfare of production animals, which have implications for breeding, management and trade. In the chicken egg production industry, the welfare impacts of this are not well understood. In the past decades, free-range systems were widely used for local chicken breeds in poultry industry in China, but their use has gradually declined due to the lower competitiveness compared to commercial cage systems.

Gender and Age Effects on Public Attitudes to, and Knowledge of, Animal Welfare in China.

A person's gender and age can influence their attitudes towards animal welfare, with more benign attitudes generally ascribed to women. Given that attitudes influence consumer behaviour and the rapid recent social development in China (globally the biggest livestock producer), we surveyed over 1300 individuals across China to elucidate the role of gender and age in determining attitudes towards animals. Respondents self-identified their gender as male, female, other or not revealed.

Effect of Peanut Shell and Rice Husk Bedding for Dairy Cows: An Analysis of Material Properties and Colostrum Microbiota.

The aim of this study was to evaluate peanut shells and rice husks as bedding for dairy cows. We analyzed material properties including dry matter, water holding capacity, pH level and bacterial counts. Bedding treatments were compared with a one-way ANOVA using twelve cows split into three groups.

Knowledge of, and Attitudes towards, Live Fish Transport among Aquaculture Industry Stakeholders in China: A Qualitative Study.

China is the largest food fish producer in the world. Chinese consumers normally purchase fish that are still alive to ensure freshness. Therefore, the live transport of fish is important in China's aquaculture, although it carries potential risks for animal welfare.

A Comparison of Rice Husks and Peanut Shells as Bedding Materials on Dairy Cows' Preferences, Behaviour, and Health.

The provision and quality of bedding materials affect the behaviour, welfare, and health of dairy cows. The objective of this study was to evaluate the preference, behaviour, cleanliness, and physiological status of cows on three bedding materials, peanut shells, rice husks, and a combination of two-thirds peanut shells, one-third rice husk. In an initial experiment, 15 nonlactating, pregnant Holstein cows had free access to all 3 bedding treatments for 39 d.

Chinese Public Attitudes towards, and Knowledge of, Animal Welfare.

Food-producing animals make up the majority of animals that humans manage globally, and China has been a major producer and exporter of animal products since the late 1990s. The opinions of the population in China regarding animal welfare are not as well understood as those in Europe. In China, animal welfare as a societal concern is still at an early stage of development.

Effects of Music Pitch and Tempo on the Behaviour of Kennelled Dogs.

Confinement can be stressful for some dogs and this can lead to behavioural issues and poor welfare. A key component of the stress response is behavioural arousal, characterised by increased alertness and sensory sensitivity. This makes behavioural observations a useful tool to assess stress, as they provide insight into an animal's internal state.

Effects of Olfactory and Auditory Enrichment on Heart Rate Variability in Shelter Dogs.

Animal shelters can be stressful environments and time in care may affect individual dogs in negative ways, so it is important to try to reduce stress and arousal levels to improve welfare and chance of adoption. A key element of the stress response is the activation of the autonomic nervous system (ANS), and a non-invasive tool to measure this activity is heart rate variability (HRV). Physiologically, stress and arousal result in the production of corticosteroids, increased heart rate and decreased HRV.

An Observational Study of the Behaviour of Captive Rehabilitant Sun Bears ().

Rehabilitant Malayan sun bears often remain in captivity for long periods of time and may experience significant welfare challenges including disability and persistent lip lesions. This study aimed to investigate whether short-term observations of behavior such as oral stereotypies are useful as noninvasive indicators of lip lesion pain, and whether behavior differs between able-bodied and disabled bears. Observations were collected from 21 captive, rehabilitant Malayan sun bears, of both sexes, a range of ages, and with lip lesions ranging in severity.

Farm Animal Welfare Science in China-A Bibliometric Review of Chinese Literature.

Farm animal welfare in the People's Republic of China (henceforth, China) is not well represented in the international scientific literature. This may lead researchers, advocates and those with agricultural partnerships in China to assume that animal welfare is not a field of interest there. This study reports a literature review of published pig and poultry welfare research in China using Chinese scientific databases.

The Effect of Animal Welfare Training on the Knowledge and Attitudes of Abattoir Stakeholders in China.

Globally, China is one of the largest producers and exporters of meat, and animal welfare is an emerging focal issue for Chinese society and for primary producers. We assessed the effectiveness of a "train the trainer" program to increase awareness of animal welfare issues in stakeholders in the livestock industries of China. Chinese abattoir employees were trained in slaughter and transportation standards in either a classroom setting or using posted materials.

Potential Impact of Construction Noise on Selected Zoo Animals.

In anticipation of a major construction project in an urban New Zealand zoo, a study was initiated to assess the response to construction noise of selected animal species (elephant, giraffe, emu and alligator) previously observed to be sensitive to this kind of noise. The overall aim was to detect any signs of aversive responses to this noise to enable keepers to recognize these and take any necessary mitigating actions during the construction period. The experimental approach involved the creation of acoustic maps of each focal animal enclosure, a series of 90-min video recordings of the animals' behavior in response to ambient noise (control) and amplified broadcast of pre-recorded continuous and intermittent construction noise.

Opportunities for refinement in neuroscience: Indicators of wellness and post-operative pain in laboratory macaques.

Being able to assess pain in nonhuman primates undergoing biomedical procedures is important for preventing and alleviating pain, and for developing better guidelines to minimise the impacts of research on welfare in line with the 3Rs principle of Refinement. Nonhuman primates are routinely used biomedical models however it remains challenging to recognise negative states, including pain, in these animals. This study aimed to identify behavioural and facial changes that could be used as pain or general wellness indicators in the rhesus macaque (Macaca mulatta).

Enclosure utilisation and activity budgets of disabled Malayan sun bears (Helarctos malayanus).

Captive bears are housed in environments that differ greatly from their natural habitat, restricting their ability to perform normal species-specific behaviours. This may be detrimental to welfare, with disabled individuals at particular risk. The effect of physical disability on behaviour and enclosure utilisation was assessed in 12 adult Malayan sun bears (Helarctos malayanus) using 10min interval scan sampling.

Facial expression: An under-utilised tool for the assessment of welfare in mammals.

Animal welfare is a key issue for industries that use or impact upon animals. The accurate identification of welfare states is particularly relevant to the field of bioscience, where the 3Rs framework encourages refinement of experimental procedures involving animal models. The assessment and improvement of welfare states in animals depends on reliable and valid measurement tools.
