I. INTRODUCTION The laying hen has a considerable requirement for dietary calcium (Ca) and phosphorus (P) to support optimum egg production, egg quality and other physiological processes. In particular, a high intake of Ca ranging from 4 to 4.5% of the diet is considered important as the laying cycle progresses from early to late lay to achieve optimum egg number and egg shell quality. A capacity for birds to increase Ca intake from a separate Ca source as dietary Ca levels diminish...

I. INTRODUCTION Contamination of eggshells by Salmonella Typhimurium is a major public health and food safety issue to the Australian poultry industry. In Australia, the majority of the egg and egg related foodborne outbreaks are caused by S. Typhimurium (The OzFoodNet Working group 2015). Biofilm formation is one of the survival mechanisms utilised by Salmonella spp. against physical and chemical stress factors in the environment (Steenackers et al. 2012). A biofilm is a...

I. INTRODUCTION It has been shown that FP occurs in all housing systems, from conventional cages, to barn and free range systems (Green et al., 2000). However, there is a lack of data available on the true prevalence of FP in commercial free-range layer farms in Australia. In a survey in the UK, 65% of flocks showed FP during lay as reported by free-range farmers but, when the same flocks were assessed by researchers, prevalence reached 89% and 69% at 25 weeks, and 73% and 86% at 40...

I. INTRODUCTION The basis for effective control of Salmonella infections in poultry production is good farm management and hygienic practices as well as testing and elimination of positive flocks in some countries. While many different measures have been recommended in meat chicken farms, vaccination with live-attenuated vaccines is likely to have a central role in the reduction of Salmonella in commercial operations by increasing the passive immunity of birds and...

I. INTRODUCTION The Australian commercial chicken industry is experiencing major changes; a significant proportion of both meat and layer farm types are becoming free range and this is driven by consumer demand (ACMF 2011; AECL 2015). Amongst industry experts, there is concern the risk of disease introduction and spread in Australian commercial chicken farms will be raised from the increased potential of interactions between wildlife and commercial chickens on free range farms (Scott...

I. INTRODUCTION Necrotic enteritis (NE) is of great concern to the poultry industry due to its deteriorating impact on production and increasing mortality, resulting in a US$6 billion global economic loss (Wade and Keyburn, 2015). The causative agent of NE is Clostridium perfringens, a gram-positive spore-forming anaerobic bacterium. The subclinical form of NE is financially more devastating than the clinical form. This is due to a lack of obvious symptoms resulting in a delayed...

I. INTRODUCTION Clay minerals and yeast fractions are regarded as effective tools for the prevention of the negative effects of toxic compounds in animal feed and production (Kubena et al., 1990; Lillehoj et al., 2016; M’Sadeq et al., 2015; Phillips et al., 1988). Clays and yeast fractions, when added to animal feeds, can adsorb certain toxic materials in the gastrointestinal tract of the animals, reducing their bioavailability. Dietary supplementation with clays has been shown...

I. INTRODUCTION In poultry meat production birds face several challenges, all of which disturb the normal functioning of the organism, with the gastrointestinal tract being the most affected. This results in impaired absorption of nutrients, leading to reduced performance and increased mortality. Previously general practice was to feed antibiotics at sub-therapeutic levels to enable birds to cope with the challenges during growth (Wati et al. 2015). With the European Union passing...

I. INTRODUCTION Microbial enzymes are now routinely used in broiler chicken diets to reduce the effects of antinutritive factors (ANF) in feed and/or improve the digestion of nutrients (Bedford, 2011). There is a suite of enzymes that target ANF such as non-starch polysaccharides (NSP) and phytic acid as well as products which improve the digestion of nutrients such as protein and minerals. The major cereals used in poultry diets are wheat, maize, sorghum and barley. The objective of...

In the world of animal feed manufacturing, some parameters shout: protein levels, energy values, additive profiles. Others whisper, quietly shaping performance from behind the scenes. Particle size is one of those silent drivers. And yet, for monogastric species like pigs and poultry, it can be the difference between optimal feed conversion and costly inefficiencies. I’ve spent over three decades in feed process technology, and if there’s one...

1. Introduction Enzymes have been developed as feed additives to improve the digestion and absorption of nutrients. The first phytase products entered the market in 1991 and have since been used extensively in monogastrics. Supplementation with exogenous phytases in cereal vegetable-based diets has been shown to improve monogastric animal production and can also contribute to breaking down phytates. This reduces phosphorus contamination and improves the utilization of phytic...

1. Introduction Recent trends in food animal production emphasize reducing antibiotic use due to the growing threat of antimicrobial-resistant bacteria [1,2]. Consequently, there is a critical need for sustainable alternatives that promote growth and health while maintaining production efficiency. Phytobiotics are plant-derived compounds that have emerged as promising candidates for this role [3]. Unlike antibiotics, phytobiotics do not contribute to antimicrobial resistance or...

1. Introduction Intestinal health is a crucial parameter in ensuring the health of birds and the optimal use of nutrients because of its various functions, namely the digestion and absorption of nutrients, the secretion of mucins and immunoglobulins, and selective protection against pathogens [1]. This topic has gained even more interest in poultry production because of increasing demands for economic efficiency, animal welfare, food safety, reducing environmental impact, and...

1. Introduction Broiler chicken feed represents approximately 75% of production costs, a figure that is expected to increase due to the commodity nature of animal feed ingredients, especially soybean oil, a primary raw material in feed production [1,2]. Currently, there are few alternative energy sources to soybean oil available for reducing production costs in poultry farming. Given these challenges, there is a growing need to explore alternative energy sources in broiler...

1. Introduction The misuse and overuse of antibiotics in humans and livestock animals are primary drivers of antimicrobial resistance [1,2], which is projected to become the leading cause of global human mortality by 2050 [1]. Consequently, the subtherapeutic use of medically important antibiotics for growth promotion and disease prevention in livestock has been banned in an increasing number of countries; however, this ban has inadvertently increased the risk of infections in...
