Infectious bursal disease (IBD) is a highly infectious and contagious immunosuppressive viral disease of chickens with a worldwide economic significance to the poultry industry. Over fifty years have passed since the first confirmed occurrence of the disease, and the virus has spread all over world and evolved into multiple genetic, antigenic and pathotypic variants, becoming a serious threat to the poultry industry. The primary tool in IBD eradication is the maintenance of strict biosecurity in poultry farms and implementation of vaccination programmes which should take into account the current epidemiological knowledge about the IBDV strains circulating in the field. This review article presents the current state of knowledge about the infectious bursal disease virus (IBDV) with special regard to the molecular biology of the virus, immunological aspects, as well as current and future prevention strategies.

Outbound logistics is a crucial field of logistics management. This study considers a planning distribution for the poultry industry in Thailand. The goal of the study is to minimize the transportation cost for the multi-depot vehicle-routing problem (MDVRP). A novel enhanced differential evolution algorithm (RI-DE) is developed based on a new re-initialization mutation formula and a local search function. A mixed-integer programming formulation is presented in order to measure the performance of a heuristic with GA, PSO, and DE for small-sized instances. For large-sized instances, RI-DE is compared to the traditional DE algorithm for solving the MDVRP using published benchmark instances. The results demonstrate that RI-DE obtained a near-optimal solution of 99.03% and outperformed the traditional DE algorithm with a 2.53% relative improvement, not only in terms of solution performance, but also in terms of computational time.

The poultry industry is one of the main providers of protein for the world's population, but it faces great challenges including coccidiosis, one of the diseases with the most impact on productive performance. Coccidiosis is caused by protozoan parasites of the genus Eimeria, which are a group of monoxenous obligate intracellular parasites. Seven species of this genus can affect chickens (Gallus gallus), each with different pathogenic characteristics and targeting a specific intestinal location. Eimeria alters the function of the intestinal tract, generating deficiencies in the absorption of nutrients and lowering productive performance, leading to economic losses. The objective of this manuscript is to review basic concepts of coccidiosis, the different Eimeria species that infect chickens, their life cycle, and the most sustainable and holistic methods available to control the disease.

Because of developing bacterial resistance and increased public awareness of health and food safety problems, the use of antibiotics as growth promoters in the chicken industry has been outlawed. This problem has spurred the poultry industry and sector to explore for safe antibiotic alternatives and to focus on developing better long-term feed management solutions in order to improve chicken health and growth. As a result, phytogenics have developed as natural antibiotic alternatives, with a lot of potential in the poultry industry. Moringa oleifera has gotten a lot of attention from researchers in the recent past as a natural product with a lot of health advantages for poultry. Moringa is known for its antimicrobial, antioxidant, anti-inflammatory, and hypocholesterolemic properties, as well as its capacity to activate digestive enzymes in the stomach, owing to the presence of hundreds of essential ingredients. The potential influence of M. oleifera as a natural feed supplement on overall gut health, nutritional digestibility, blood biochemical profile, antioxidant benefits, antibacterial potential, and immunological response is emphasized in this review.

<p>Within the New Zealand poultry industry press between 1900 and 1960, scientific approaches were promoted and ‘sentimentality’ discouraged, yet comparative and anthropomorphic description suggesting similarities between chickens and humans persisted. Feathered Friends and Human Animals explores this phenomenon within poultry journals, newspapers, advice books and official publications. Four key themes of comparison are identified: ideas about the chicken mind, the chicken-as-worker, poultry ‘eugenics’, and health and hygiene.  It is argued that humanitarian, theological, and philosophical ideas, the ‘natural’ empathetic and humoured identification that arises through everyday contact with animals within relatively small systems, and the rationalisation of industry, were all significant factors contributing to sustained comparison. However, the public articulation of fundamental biological ideas – encapsulated in the modern, overarching concept of ‘general biology’ – validated and integrated these discourses.  General biology influenced new trends in education and in the popular and public articulation of research into the life sciences of this period. It encouraged the integration of sympathetic naturalist persepectives, including evolutionary based ideas about ‘natural laws’, with emerging new science that continued to establish many fundamental biological principles through extrapolation from experimental animals to human animals. This study demonstrates that poultry experts’ attended to this same blend of older naturalist science and new scientific knowledge.  Historians’ focus on emerging specialist science in the early twentieth century has tended to obfuscate the realities of science education within the applied sciences and amongst lay audiences, and the continued interest in fundamental aspects of biology within professional science. The findings of this study reveal that farming ideas did not develop within a bubble, determined only by animal husbandry traditions and industry-specific applied research. They also suggest that practitioners’ conceptions of biology within applied fields of this era were not as distinct as has been supposed.  As a ‘bottom-up’ cultural history of science, this study illustrates the articulation of general biology within an agricultural context. This is the key contribution offered to local and international historiography. However, other elements of the study expand existing scholarship. In exploring ideas about race and eugenics, it offers a broader framework for social historians, who, while cognisant of the eugenic mind-set of this period, have granted little attention to general biology as a professional trend. It offers insight into the agendas and tensions within school nature study and elementary science. It is also the first comprehensive history of the New Zealand poultry industry. Poultry-keeping engaged up to around 60 percent of the nation’s households in this period, including thousands of farmers who kept sideline flocks, but as a predominantly domestic (as opposed to export) industry it has been overlooked by social and agricultural historians.  The field of human animal studies, which has tended to gloss over both this era of transition prior to modern agribusiness and scientific discourses, is also advanced by this study, and this is the first New Zealand agricultural history to engage with this field and examine animal husbandry ideologically. It reveals how fundamental science knowledge, entwined with moral perspectives, continued to shape ideas about animals’ needs and behaviour well beyond the Victorian period. Assumptions of similarity however, were not always beneficial for the animal, and human-bird comparison was used to both justify and deny kind treatment.</p>

We propose a measure of temporal light quality that could be used to design flicker-free light sources, as perceived by birds. It can be applied to, among others, the poultry industry to reduce the negative impact of the modulated light on chicken health and well-being. The model is built by modifying an existing human flicker visibility model considering properties of bird vision. We discuss the implications of the model responses on the temporal quality of relevant historical light sources.

The poultry industry contributes majorly to the food industry. The demand for poultry chickens raises across the world quality concerns of the poultry chickens. The quality measures in the poultry industry contribute towards the production and supply of their eggs and their meat. With the increasing demand for poultry meat, the precautionary measures towards the well-being of the chickens raises the concerns of the industry stakeholders. The modern technological advancements help the poultry industry in monitoring and tracking the health of poultry chicken. These advancements include the identification of the chickens’ sickness and well-being using video surveillance, voice observations, ans feces examinations by using IoT-based wearable sensing devices such as accelerometers and gyro devices. These motion-sensing devices are placed over a chicken and transmit the chicken’s movement data to the cloud for further analysis. Analyzing such data and providing more accurate predictions about chicken health is a challenging issue. In this paper, an IoT based predictive service framework for the early detection of diseases in poultry chicken is proposed. The proposed study contributes by extending the dataset through generating the synthetic data using Generative Adversarial Networks (GAN). The experimental results classify the sick and healthy chicken in a poultry farms using machine learning classification modeling on the synthetic data and the real dataset. Theoretical analysis and experimental results show that the proposed system has achieved an accuracy of 97%. Moreover, the accuracy of the different classification models are compared in the proposed study to provide more accurate and best performing classification technique. The proposed study is mainly focused on proposing an Industrial IoT-based predictive service framework that can classify poultry chickens more accurately in real time.
