A recent study suggests that artificial Ascardia galli infection has no effect on performance and egg quality of free-range laying hens from the point of lay until 40 weeks of age (Sharma et al., 2017). However, the lower hepatic lipid reserve of infected hens observed in the same study indicated the potential for A. galli to affect production at a later stage. In this study, serum and yolk antibo ...

Reduced protein (RP) diets have received increasing interest in poultry nutrition due to the potential benefits in feed cost and environmental footprint (Liu et al., 2021). Understanding the order of limiting amino acids (AA) in RP diets is critical to ensure requirements are met cost effectively. To date, only the first three limiting AA (including lysine [Lys], methionine [Met], and threonine [T ...

I. INTRODUCTIONFeeding the world’s projected burgeoning human population increase of 2.2 billion people by 2050 will place tremendous pressure on food security. The poultry industry is innovative and well positioned to address this problem through increased efficiency and waste reduction. Globally, 32% (by weight) of produced food − equivalent to 1.3 billion tons − is lost or was ...

An estimated 7.3 million tonnes of food waste are dumped annually in Australia, leading to substantial environmental and economic losses (Arcadis, 2019). Additionally, poultry feed represents the majority of production cost. Therefore, an experiment was designed to evaluate food waste as a feed for laying hens. A total of 150 Isa Brown laying hens at 24 weeks of age were allocated to 3 treatments ...

Nutritional strategies to improve performance of broilers offered reduced crude protein (RCP) diets supplemented with crystalline amino acids are of interest to the poultry industry. We hypothesized that the dietary inclusion of moderate amounts of insoluble fibre would stimulate gizzard function and increase the retention time of digesta in the foregut allowing more time for exogenous protease to ...

Water is important for the overall health and performance of birds, yet less focus has been on water compared to the other nutrients. Increase or decrease in water to feed intake ratio (WI:FI) indicates issues related to nutrition, health or management of the shed particularly in broilers due to their fast growth. An automated water measurement system was developed at the University of New England ...

Necrotic enteritis (NE) is an enteric disease of poultry caused mainly by a spore-forming grampositive bacterium, Clostridium perfringens, resulting in decreased growth, high mortality, and increased veterinary costs (Wade and Keyburn, 2015). While supplementing poultry diets with antibiotics can control NE, emerging antibiotic-resistant microbes and transfer of such resistance factors into human ...

Recent studies have shown that the decreased performance of broilers associated with feeding a reduced crude protein (RCP) diet cannot be fully recovered by supplementing essential amino acids (Hilliar et al., 2019). We hypothesized that the dietary inclusion of moderate amounts of insoluble fibre would improve gizzard function and protein/amino acid digestibility that could help to restore the pe ...
