Purpose – The purpose of this research is to design and build a wild animal pest repellent device with combination of passive infrared (PIR) sensor and ultrasonic signal based on microcontroller as system controller. The PIR sensor is used to detect the presence of wild animal objects and ultrasonic signals to interfere with the hearing.

Design/Methodology/Approach – The design of the system is built based on microcontroller as the system controller. The system as a whole includes hardware and software. The design of hardware consists of the system design on the transmitter side and the system design on the receiver side, while the software in the of system are algorithms using C language programming.

Findings – The resulting repellent device can detect animals approaching up to a distance of 5 m and may interfere with its hearing with a 40 kHz ultrasonic frequency up to a distance of 20 m. The system also uses remote monitoring devices using 433 MHz radio frequency up to a distance of 60 m.

Research Limitations/Implications – Each animal has different hearing frequencies, as well as some wild animals, but the hearing frequencies of wild animals are generally at ultrasonic frequencies. The frequency of animal hearing may vary from audio frequency to ultrasonic frequency, so ultrasonic wave emission testing with varying frequencies is required.

Practical Implications – This research combines systems on transmitters and receivers, with real-time monitoring of wild animal positions, and it can be possible to monitor the position of more detailed animals by installing more types of sensors as well as increasing the number of sensors.

Originality/Value – This paper may provide additional insight into the hearing frequencies of animals and may also serve as comparable papers for similar studies.

The purpose of this paper is to explore the attitude of pig farmers toward animal welfare in light of the state‐of‐the‐art legislation on animal welfare and production schemes in Italy.

The general framework regarding pig production, legislation and production schemes will be described by a literature review and personal communications from experts in the field. The results of farmers' attitudes toward animal welfare are based on a survey carried out among pig producers.

The main findings of the research are related to the survey results among pig producers. The paper presents a short description of the Italian pig sector and the results of the animal welfare legislation and production schemes.

The main limitation of the study is the relatively limited number of survey interviews. For this reason the sample cannot be considered statistically representative of the whole country.

The information collected in this article could represent a useful source for farmers, policy makers, and retailers, as well as consumers interested in animal welfare issues.

This is the first time that pig producers have been asked to express their opinion on animal welfare as defined by the legislation in force and the existing production schemes.

The purpose of this paper is to describe the main characteristics of the animal welfare specifications in different quality schemes of the French pig sector; to present the French pig farmers' attitudes towards animal welfare in general, and illustrate different quality schemes.

Prime source of data is interviews with 60 pig farmers. Supplementary sources are research reports and statistics, specifications of the quality schemes.

On many themes, the responses and attitudes of the farmers differ according to their participation or not in a quality assurance scheme, and according to the level of stringency of their scheme regarding animal welfare. For instance, farmers in the most stringent schemes define animal welfare as providing natural living conditions for the animals, whereas for farmers in no schemes, or in more intensive schemes, animal welfare is above all an animal in good health, for which one must provide correct housing and a balanced and sufficient diet. Animal welfare is almost always a part of more global quality schemes including environmental and high flavour quality aspects.

The paper provides insights into the different definitions of good animal welfare by French pig farmers, as well as their attitudes towards public regulations and different types of private schemes. This is interesting from a scientific point of view and to fuel the debate between a high level of regulation for all farmers, a market segmentation based on welfare specification, or a market segmentation in which animal welfare is one aspect of the specifications.

This paper reviews the possibilities of coronavirus disease 2019 (COVID-19) spreading from infected humans to pet animals and from pet animals to other animals and humans.

A systematic literature review and meta-analysis were performed on research articles from November 2019 to August 2020. This study explored urgently needed research issues on COVID-19 infection spreading across animals and humans and vice versa.

Essential and much needed precautionary measures and necessary preventive steps to protect pet animals from infection were highlighted.

Essential investigation and experiment results were highlighted. The necessary measure to prevent the spread of infection among and across species and people was analyzed.

Studies on developed economies showed that imposing taxes on animal-based foods could effectively reduce agricultural greenhouse gas emissions (AGHGEs), while this taxation may not be appropriate in developing countries due to the complex nutritional status across income classes. Hence, this study aims to explore optimal tax rate levels considering both emission reduction and nutrient intake, and examine the heterogenous effects of taxation across various income classes in urban and rural China.

The authors estimated the Quadratic Almost Ideal Demand System model to calculate the price elasticities for eight food groups, and performed three simulations to explore the relative optimal tax regions via the relationships between effective animal protein intake loss and AGHGE reduction by taxes.

The results showed that the optimal tax rate bands can be found, depending on the reference levels of animal protein intake. Designing taxes on beef, mutton and pork could be a preliminary option for reducing AGHGEs in China, but subsidy policy should be designed for low-income populations at the same time. Generally, urban residents have more potential to reduce AGHGEs than rural residents, and higher income classes reduce more AGHGEs than lower income classes.

This study fills the gap in the literature by developing the methods to design taxes on animal-based foods from the perspectives of both nutrient intake and emission reduction. This methodology can also be applied to analyze food taxes and GHGE issues in other developing countries.

The use of multi-level labels can enhance product visibility by enabling labeling of various items. Moreover, it can better accommodate the diversity on both the producer and consumer sides. However, studies on the willingness to pay (WTP) for premium levels of those animal welfare labels are scarce.

We investigate consumers’ WTP for a four-level animal husbandry label introduced to the market by German retailers in 2019 by conducting an online survey with 1,223 German meat consumers using Van Westendorp’s price sensitivity meter (PSM).

There is a significant increase in WTP for level 3 of the husbandry label, but only a slight increase for level 4. One explanation is that consumers may have the mistaken belief that level 3 already includes outdoor access for animals. As a result of this expectation, consumers may not perceive much added value in level 4, which is reflected in their reluctance to pay a higher price. This is reinforced by the finding that once informed of the criteria, 18% of the participants reduced their WTP for level 3, whereas only 6% considered a discount for level 4. Furthermore, 40% were prepared to pay more for level 4 after being informed of the respective criteria than they had previously stated.

To the best of our knowledge, this study is the first to analyze and emphasize the importance of clear label communication, particularly for multi-level animal husbandry labels.

This chapter reviews factors responsible for climate change, impacts of the change on animal health, zoonotic diseases, and their linkage with One-Health program.

This chapter is based on the available literature related to climate change and its effect on animal health and production from different points. The causes and change forcers of climate change, direct and indirect effects of the change on animal health management, host–pathogen–vector interaction, and zoonotic diseases are included. Inter-linkage between climate change and One-Health program are also assessed.

Beside natural causes of climatic change, greenhouse gases are increasing due to human activities, causing global climate changes which have direct and indirect animal health and production performance impacts. The direct impacts are increased ambient temperature, floods, and droughts, while the indirect are reduced availability of water and food. The change and effect also promote diseases spread, increase survival and availability of the pathogen and its intermediate vector host, responsible for distribution and prevalence of tremendous zoonotic, infectious, and vector-borne diseases. The adverse effect on the biodiversity, distribution of animals and micro flora, genetic makeup of microbials which may lead to emerging and re-emerging disease and their outbreaks make the strong linkage between climate change and One-Health.

Global climate change is receiving increasing international attention where international organizations are increasing their focus on tackling the health impacts. Thus, there is a need for parallel mitigation of climate change and animal diseases in a global form.

Most research on climate change is limited to environmental protection, however this chapter provides a nexus between climate change, animal health, livestock production, and the One-Health program for better livelihood.

The last few decades have seen the rise of a new field of inquiry – human–animal studies (HAS). As a rich, theoretically and disciplinarily diverse field, HAS shines a light on the various relations that humans have with other animals across time, space and culture. While still a small, but rapidly growing field, HAS has supported the development of multiple theoretical and conceptual initiatives which have aimed to capture the rich diversity of human–animal interactions. Yet the methodologies for doing this have not kept pace with the ambitions of such projects. In this chapter, we seek to shed light on this particular issue.

We consider the difficulties of researching other-than-human beings by asking what might happen if methods incorporated true inter-disciplinarity, for instance if social scientists were able to work with natural scientists on multi-species ethnographies. The lack of established methodology (and the lack of cross disciplinary research between the natural and social sciences) is one of the main problems that we consider here. It is an issue complicated immensely by the ‘otherness’ of animals – the vast differences in the ways that we (humans) and they (animals) see the world, communicate and behave. This chapter provides the opportunity for us to consider how we can take account of (if not resolve) these differences to arrive at meaningful research data, to better understand the contemporary world by embarking upon more precise investigations of our relationships with animals.

Drawing upon a selection of examples from contemporary research of human–animal interactions, both ethnographic and scientific, we shed light on some new possibilities for multi-species research. We suggest that this can be done best by considering and applying a diversity of theoretical frameworks which deal explicitly with the constitution of the social environment.

Our methodological exploration offers the reader insight into new ways of working within the template of human animal studies by drawing upon a range of useful theories such as post-structuralism and actor network theory (ANT) (for example, Callon, 1986; Hamilton & Taylor, 2013; Latour, 2005; Law, Ruppert, & Savage, 2011) and post-humanist perspectives (for example, Anderson, 2014; Haraway, 2003; Wolfe, 2010). Our contribution to this literature is distinctive because rather than remaining at the philosophical level, we suggest how the human politics of method might be navigated practically to the benefit of multiple species.
