“…Several studies have used sound (more specifically the sound of jaw movements or pecking) as a proxy for feeding in farmed ungulates and chickens [e.g., ( 43 – 46 )], allowing farmers to monitor feed intake and general behavior patterns. The sex and genetic strain of intensively reared (broiler) chicks have been rapidly identified through their vocalizations, compared to very time-consuming and costly visual or genetic methods ( 47 ). The authors ( 47 ) found that the second formant, which is a specific acoustic measurement related to how the sound wave resonates, could reliably be used to identify chick sex and strain.…”

Sound is a complex feature of all environments, but captive animals' soundscapes (acoustic scenes) have been studied far less than those of wild animals. Furthermore, research across farms, laboratories, pet shelters, and zoos tends to focus on just one aspect of environmental sound measurement: its pressure level or intensity (in decibels). We review the state of the art of captive animal acoustic research and contrast this to the wild, highlighting new opportunities for the former to learn from the latter. We begin with a primer on sound, aimed at captive researchers and animal caregivers with an interest (rather than specific expertise) in acoustics. Then, we summarize animal acoustic research broadly split into measuring sound from animals, or their environment. We guide readers from soundwave to soundscape and through the burgeoning field of conservation technology, which offers new methods to capture multiple features of complex, gestalt soundscapes. Our review ends with suggestions for future research, and a practical guide to sound measurement in captive environments.

“…Sound analysis could identify the sex of 1-day-old chickens as well as different genetic strains (Cobb and Ross chickens) (Pereira et al, 2015). Analysing four acoustic sound characteristics showed that the second spectral peak of the sound spectrum could identify the sex of chicks, and both the second spectral peak and the pitch could identify the genetic strain.…”

Review: Automated techniques for monitoring the behaviour and welfare of broilers and laying hens: towards the goal of precision livestock farming

There is increasing public concern about poultry welfare; the quality of animal welfare is closely related to the quality of livestock products and the health of consumers. Good animal welfare promotes the healthy growth of poultry, which can reduce the disease rate and improve the production quality and capacity. As behaviour responses are an important expression of welfare, the study of behaviour is a simple and non-invasive method to assess animal welfare. The use of modern technology offers the possibility to monitor the behaviour of broilers and laying hens in a continuous and automated way. This paper reviews the latest technologies used for monitoring the behaviour of broilers and laying hens under both experimental conditions and commercial applications and discusses the potential of developing a precision livestock farming (PLF) system. The techniques that are presented and discussed include sound analysis, which can be an online tool to automatically monitor poultry behaviour non-invasively at the group level; wireless, wearable sensors with radio-frequency identification devices, which can automatically identify individual chickens, track the location and movement of individuals in real time and quantify some behavioural traits accordingly and image processing technology, which can be considered a direct tool for measuring behaviours, especially activity behaviours and disease early warning. All of these technologies can monitor and analyse poultry behaviour, at the group level or individual level, on commercial farms. However, the popularity and adoption of these technologies has been hampered by the logistics of applying them to thousands and tens of thousands of birds on commercial farms. This review discusses the advantages and disadvantages of these techniques in commercial applications and presents evidence that they provide potential tools to automatically monitor the behaviours of broilers and laying hens on commercial farms. However, there still has a long way to go to develop a PLF system to detect and predict abnormal situations.

“…Bioacoustics based system has been developed to detect the sex (Pereira et al 2015 ), routine activities of poultry (Fontana et al 2016 ), disease diagnosis like necrotic enteritis (Sadeghi et al 2015 ). A sound detection system has been developed to differentiate between New Castle Disease, Infectious Bronchitis, and Avian Influenza (Banakar et al 2016 ).…”

Animals play a vital role in our lives as they provide milk, meat, and other by-products for daily consumption. At the same time, their health directly/indirectly affects human beings as we both share a common environment. The One Health concept makes it imperative that the animals should remain healthy as it will have an impact on our health as well as economy. Animal disease diagnosis, their health monitoring, prevention, and control of diseases are important from this aspect. Tools for rapid diagnosis of animal diseases are crucial for early diagnosis and imposing control measures. Molecular techniques such as, genome sequencing, restriction fragment length polymorphism (RFLP), DNA microarray, PCR, and real-time PCR are some of the rapid techniques, but they need expertise and sophisticated labs. Conventional methods such as isolation of the pathogen, serological techniques, are laborious and time taking process. Therefore, to overcome the said limitations of conventional and molecular tools, biosensors are the better alternatives as they are rapid and can be used as pen-side diagnostic tests. They can provide test results in a few minutes under field conditions. In this chapter, we give an elaborative description of various types of biosensors and their utility in animal disease diagnostics and health monitoring.
