The ancestor of the modern-day chicken, the red jungle fowl, was exposed to different spectra of light in their natural habitat (Prescott et al., 2003). The surrounding environment, vegetation, season, and time of day all affect the color of light exposure to the wild bird (Endler, 1993), which may have lingering behavioral...

1. Introduction Salmonellosis is among the major causes of foodborne gastrointestinal infection in humans worldwide [1] and the second cause following campylobacteriosis in the European Union (EU) [2]. Particularly, non-typhoidal Salmonella spp. (NTS) are one of the bacterial pathogens with the highest disease burden among human foodborne enteric diseases [3]. Poultry products are considered as a major source of human infection in cases of foodborne salmonellosis caused by NTS [4]....

1. Introduction Aflatoxin B1 (AFB1), a toxic metabolite produced by Aspergillus flavus and Aspergillus parasiticus, is one of the most potent naturally occurring carcinogens [1]. It poses significant risks to animal health and productivity, particularly in poultry, where the contamination of feed is a prevalent issue [2]. Broiler chickens are highly susceptible to the adverse effects of AFB1 due to their rapid growth rates and high feed intake [3]. Recent studies have...

1. Introduction There is considerable interest in the successful development of low protein diets for broiler chickens, which axiomatically contain high inclusions of supplemental amino acids. This is because low protein diets have the potential to generate economic, environmental and bird welfare advantages. Formulation of low protein diets are usually achieved by decreasing...

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...
