1. Introduction Poultry refers to avian species (e.g., Gallus gallus domesticus—chicken; Anas platyrhynchos domesticus—duck) housed in a diversity of production systems (e.g., organic, free-range and conventional structures) that are dedicated to the production of poultry products, specifically chicken meat and table eggs for human consumption and eggs hatching for reproduction [1,2]. Bacterial contamination in poultry can be initiated by ingestion of contaminated feed or...

1. Introduction Avian metapneumovirus (aMPV) is a highly infective virus that affects turkeys and chickens, causing turkey rhinotracheitis (TRT) and swollen head syndrome (SHS), respectively. aMPV also has the capacity to infect other avian species [1–3]. The virus is primarily associated with upper respiratory infections, predisposing birds to opportunistic bacterial pathogens, which can result in severe respiratory disease, high morbidity, and mortality rates....

1. Introduction The Newcastle disease virus (NDV), a member of the Paramyxoviridae family, poses a global threat to poultry and wild birds due to its worldwide distribution and ability to infect various avian species [1]. Infection of birds with highly virulent strains of NDV results in immunosuppression, which at least in part results from profound depletion of lymphoid tissues [2,3]. NDV has also been extensively studied in human tumour cells for its potential role as...

1. Introduction S. Infantis currently ranks among the top 10 serovars associated with human infections, standing as the fourth leading cause of salmonellosis cases in the EU [1]. Recent data from the European Food Safety Authority (EFSA) indicated that 95.6% of the Salmonella isolates in broiler flocks belong to the Infantis serovar, demonstrating a close association with poultry production [2]. In recent years, the increasing incidence of S. Infantis infections in both humans...

Using evaporative cooling to keep birds cool during hot weather is relatively simple. Water is circulated over paper pads. Tunnel fans pull hot outside air through the pads and into the house. As the air moves through the wetted pads, its temperature decreases. Fairly straightforward. On the other hand, understanding how evaporative...

When designing a tunnel-ventilated house, it is important to install the proper amount of evaporative cooling pad. Too little pad will result in excessive static pressure, which will reduce air speed, and therefore bird cooling. Too much pad will result in increased initial cost, more pads to maintain/replace, and a larger area of reduced air movement near the tunnel inlet end wall. Pad area is based not on the size of a house but rather on the air-moving capacity of a house's...

A poultry house controller's temperature sensors are, in a sense, its "eyes" enabling it to “observe” what is happening throughout a poultry house so it can accurately determine what equipment it needs to operate to maintain the proper environmental conditions throughout a house. As a result, a...

Thanks for the information. Almost all companies in the current feed additive premix sector are working on developing a product on this subject. These issues have been on the agenda since 1996 (maybe even earlier) and companies that understood that this would be a problem in the future started to develop the technologies you mentioned starting from that date. There are good products on the market that increase the prebiotic effect by supporting it with FOS in addition to active ingredients....

1. Introduction Coccidiosis is a significant poultry disease caused by single-celled protozoa of the genus Eimeria, including Eimeria acervulina, Eimeria brunetti, Eimeria maxima, Eimeria mitis, Eimeria necatrix, Eimeria praecox, Eimeria tenella, Eimeria lata, Eimeria nagambie, and Eimeria zaria, which are known to be the species responsible for coccidiosis in chickens (Gallus gallus domesticus) [1,2]. Among them, E. tenella and E. necatrix are recognized to be the most...

Avian Influenza Virus (AIV) poses a significant threat to both avian populations and human health due to its potential for zoonotic transmission. The emergence of highly pathogenic strains necessitates the development of innovative control strategies. This abstract presents a comprehensive overview of the potential of CRISPR-based technologies, Quorum Sensing (QS) systems, and the application of the synthetic inducer molecule Arbitrium as strategic control measures for mitigating AIV...

South American countries such as Argentina, Chile, Brazil, Paraguay, Peru, and Uruguay reported the detection of HPAIV H5N1 clade 2.3.4.4 b in domestic and wild birds for the first time in the region from the end of 2022 to the beginning of 2023. Human infections were reported for the first time in South America, Ecuador, and Chile. Since October 2022, the PREVIR-MCTI network, a Brazilian network for virus surveillance in wild animals, has been collecting samples from asymptomatic wild...

Damaging behaviors in poultry include feather pecking, vent pecking, and toe pecking. While feather and vent pecking are well-known welfare problems in poultry that have received significant attention from researchers and farmers, toe pecking remains relatively unknown. Therefore, this article aims to shed...
