I. INTRODUCTION Production improvements in commercial meat chickens via genetic selection and improved husbandry have resulted in rapid growing birds. These birds have endemically reduced locomotor ability; a conservative estimate is that 30% of birds in a flock are likely to have poor mobility (Knowles et al, 2008). Leg weakness has a direct impact on production due to lower bird quality, which may result in culls or condemnation of carcasses. While not well understood, early rapid...

I. INTRODUCTION Non-therapeutic in-feed usage of antibiotics in animal diets has been implicated in development of antibiotic-resistant bacteria, some of which are zoonotic and pathogenic to humans (Stanton, 2013). Based on this fact, the European Union placed a ban on such usage of antibiotics 12 years ago (European commission, 2005; Castanon, 2007). However, the continuous incidence of antibiotic resistance in other regions is fueling the consideration and legislation of a global...

I. INTRODUCTION Exogenous feed enzymes were first introduced as commercially-relevant feed additives in the 1980s with an initial focus on reduction of the antinutritional effects of high molecular weight soluble pentosans in wheat- and barley-based diets for young broiler chickens (Bedford & Partridge, 2010). Exogenous phytase was launched in the early 1990s to increase the digestibility of organic phosphorus and to reduce the antinutritional effects of phytic acid (Selle &...

I. INTRODUCTION The digestive dynamics of starch and protein are considered pivotal to broiler performance (Liu and Selle, 2015). Moreover, it was proposed that the rates of starch digestion and glucose absorption exceed the rates of protein digestion and amino acid absorption and this asynchrony in digestive dynamics compromises the performance of broiler chickens. If so, it follows that the provision of rapidly-digestible protein should enhance broiler performance in a reciprocal...

I. INTRODUCTION In Australia, the National Animal Welfare Research Development and Extension (RD&E) Strategy is a cross-sectoral strategy under the National Agricultural RD&E Framework. Each of the livestock industries in Australia, including the egg industry, is represented by this National Strategy, which is active in identifying the key areas of importance for the welfare of livestock. Over the last four to five years, in particular, this National Strategy has consistently...

INTRODUCTION Feed particle size is an often-overlooked aspect of poultry production. Producers should not assume that feed is of a uniform size and homogeneously mixed, or that the feed mill is providing the ideal mix of particles in a ration. Feed particles range in size from very fine to coarse, and different grinding methods will result in different particle size distributions. Differences in particle size within a ration can affect both the digestive system and the...

1. Introduction Antimicrobial resistance (AMR) is a phenomenon where microorganisms develop resistance to specific antimicrobial agents, posing serious health risks [1]. According to conservative estimates, AMR is projected to be responsible for 10 million deaths annually by 2050 [2]. Currently, the European Union (EU) reports that over 670,000 infections are linked to AMR each year, resulting in nearly 33,000 deaths directly attributable to confirmed resistance [3]. Poultry...

1. Introduction Antimicrobials have revolutionized modern medicine by enabling effective treatments for many life-threatening diseases and saving countless lives. However, the emergence and spread of antimicrobial resistance (AMR) among pathogens has become a global health issue affecting humans, animals, and environment [1]. Recognizing AMR as a critical challenge, the World Health Organization (WHO) has emphasized the urgent need for concerted efforts to combat this growing threat...

1. Introduction Avian Reovirus (ARV) poses a significant threat to the poultry industry, infecting both domestic and wild avian species. ARV infections manifest in a diverse range of clinical signs, encompassing tenosynovitis/arthritis, immunosuppression, enteric disease, hepatitis, myocarditis, malabsorption, and runting–stunting syndrome [1,2]. While domestic avian species are generally susceptible to ARV, meat-type chickens and turkeys [3,4] are, however, more susceptible to...

I. INTRODUCTION Chicken meat and egg production has been on the increase in all continents with the highest increases in Asia and South America (Mandal, 2010). High temperatures coupled with high humidity impose severe stress on birds and can cause huge economic loss. Such loss is due to reduced performance, immune suppression, and an increase in respiratory disease and mortality (Mandal, 2010). Exposure of chickens to high temperature also increases the induction of heat shock...

I. INTRODUCTION Bacillus-based probiotics have gained increased attention as alternatives to antibiotic growth promoters (AGP) to support broiler performance in systems aiming to reduce the use of antibiotics and maintain gut health and function. Combatting poor gut health and disease susceptibility in an era without antibiotics has been made increasingly difficult due to the increasing cost of commercial feed ingredients. This has forced some producers to use cheaper dietary...

I. INTRODUCTION Egg-associated Salmonella infection is a significant international public health problem. Internal contamination of eggs with S. Enteritidis has been the principal concern in North America and Europe, whereas external contamination with S. Typhimurium has been the predominant issue in Australia. Some strategies for controlling egg-borne Salmonella are designed to act with precision against epidemiologically important serovars, but others are applicable...
