Low protein diets are being investigated to reduce feed cost and address health, welfare and environmental concerns associated with feeding meat chickens excess dietary crude protein (CP). Low CP diets supplemented with only essential amino acids (AA) have failed to improve performance to that observed with standard CP diets (Dean et al., 2006). The nonessential amino acid glycine (Gly) is believe ...

I. INTRODUCTIONThe meat chicken industry is growing rapidly as a result of an increasing population, relatively low production costs and excellent marketability with regards to affordability, sustainability and minimal religious restrictions. Poultry diets with lower crude protein (CP) have generated global interest from the meat chicken industry due to the benefits concluded by published literatu ...

Copper (Cu) is a vital element involved in cellular metabolism and enzyme systems. At levels greater than nutritional requirements, dietary Cu addition enhances growth performance as a growth promoter (Pesti and Bakalii, 1996). Copper dosing at levels up to 250 mg/kg feed has been shown to improve intestinal structure and function, and alter the intestinal microbiota profile (Di Giancamillo et al. ...

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 ...

Hydroxychloride trace minerals (HTM) have covalent bonds and thus are less reactive both in the feed and in the digestive tract compared to inorganic trace minerals, which contain ionic bonds (ITM) such as sulphate forms. Therefore, HTM may have higher bioavailability than ITM.This study aimed to evaluate the effects of replacing sulphate forms of zinc (ZnSO4), manganese (MnSO4) and copper (CuSO4) ...

Trace minerals are often supplied in the forms of inorganic salts such as sulphates into poultry feed to meet the requirements. The ionic bonds in inorganic salts of minerals are very weak allowing the metal ion to disassociate once in contact with water, binding up diet antagonists such as other minerals, vitamins, and enzymes. To mitigate these negative effects technologies such as organic miner ...
