Poultry genetics and reproduction
Poultry breeding has been one of the most impactful advances in the last 100 years. The role that improved global production of eggs and poultry meat have in reducing global hunger and food insecurity is difficult to overstate. The vast majority of these improvements have come from genetic selection for improved feed efficiency, along with streamlining of the overall production system, and better understanding of poultry nutrition. While the industrial approach to poultry production has created a highly consistent and dependable food source the world over, several problems threaten the long term sustainability of this model - including musculoskeletal and metabolic disorders, welfare concerns, and the need to adapt to a changing climate. Researchers in poultry breeding and genetics utilize quantitative, population, and molecular genetic techniques to help understand the effects of selection for economically important traits and enhance genetic performance through changes in environment and management strategies.

INTRODUCTION Foodborne infections caused by Salmonella enterica are of primary importance worldwide. The WHO estimates that Salmonella causes more than 153 million illnesses, 120,281 deaths, and 8.27 million disability-adjusted life years annually (1). As foodstuffs can be contaminated in several parts of the food chain, a “from farm to table” approach is necessary to understand the epidemiology of Salmonella. Although Salmonella can contaminate vegetables, food-producing...

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....

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...

INTRODUCTION Non-typhoidal Salmonella (NTS) enterica subsp. enterica is a foodborne pathogen that causes »1.2 million infections in the United States of America (USA) annually (Scallan et al., 2011), and was responsible for more than 95 million cases of diarrheal disease and 50,771 deaths worldwide in 2017 (Stanaway et al., 2019). Human infections are usually mild and manifest as a self-limiting gastroenteritis. However, high-risk populations such as the infants, the elderly,...

Nontyphoidal Salmonella (NTS) represents one of the leading causes of foodborne gastroenteritis worldwide (1, 2). The global burden of NTS infections is 93.8 million cases, and it is estimated that NTS causes around 155,000 deaths annually (3). Unfortunately, there is a lack of information about surveillance studies of NTS in Latin American countries, and reports on NTS outbreaks are scarce in this region (4). In South American countries, there has been an increase in reports of...

Avian influenza (AI) significantly threatens global poultry production and public health. Efforts to combat this viral disease have been predominantly focused on vaccination strategies, with limited success in controlling its spread. This study explores a novel approach utilizing genome editing techniques to enhance avian influenza resistance in chickens. Specifically, we employ CRISPR-Cas9 technology to target the ANP32 genes, endogenous proteins co-opted by influenza for replication in...

I. INTRODUCTION Brooding chicks with maternal care can improve the welfare of chicks; specifically, by improving prosocial behavior and reducing feather pecking (Edgar et al., 2016). Yet providing chicks mother hens in industry is impractical and a biosecurity risk. Artificial components of maternal care may provide some benefits to chicks and improve welfare. Indeed, there is some evidence that lighting that mimics the maternal environment, synthetic maternal olfactory cues and...
