Copper (Cu) is a vital element involved in various physiological and biochemical processes, namely cellular metabolism and enzyme systems. Higher levels of copper than nutritional requirements (up to 250 mg/kg) are supplemented to poultry diets. However, if in excess, excreted Cu can contaminate the environment. High levels of copper sulphate (CuSO4) may damage other dietary nutrients through incr ...

Really good discussion. Certainly will be great to have such discussion face-to-face once again!

Dear Markus,
Thanks. I will call Amy Liu here in Australia to enquire.
Kind regards,

I. INTRODUCTIONThe withdrawal of antibiotics has caused an increased prevalence of necrotic enteritis (NE) in broiler chickens, making it the most common disease in the poultry-industry globally. Direct fed microbials (DFMs) have been shown to have great potential as alternatives to antibiotic growth promoters (AGPs). Bacillus amyloliquefaciens produces several extracellular enzymes including cell ...

One benefit of low protein (LP) diets is improving gut health in a future of antibiotic-growth promoter free diets. Drew et al., (2004) found an interaction between dietary crude protein (CP) and proliferation of Clostridium perfringens, a pathogenic bacterium identified to cause clinical and sub-clinical necrotic enteritis (NE), which costs the poultry industry US$6 billion dollars annually (Wade ...

Low protein (LP) diets have clear benefits for the poultry industry with regards to health, welfare and production. Dean et al., (2006) found that supplementing LP diets with glycine (Gly) and essential amino acids (AAs) can maintain performance similar to that seen on a standard protein (SP) diet. Further research into this concept proposes that supplementation of Gly precursors such as threonine ...

Calcium is an important cation in chicken diets, being the most abundant element in the body of the chicken. Its functions include: mineralization of bones, blood clotting, enzyme activation, neuromuscular function, muscle contraction, and intracellular signaling. However, high dietary Ca is a limiting factor for phytase efficacy and the formation of insoluble Ca-phytate complexes decreases Ca and ...

Traditionally, Zn, Cu and Mn have been added to poultry diets in the form of inorganic salts, such as sulphate, to meet requirements and prevent deficiencies. The sulphate sources of trace minerals have low bioavailability, are highly water soluble and reactive in the feed and digestive tract (Ma et al., 2011). Hydroxychloride minerals (HyC) are a class of naturally occurring minerals with fully d ...

I. INTRODUCTIONThe most important cost component of broiler feed relates to energy, as this may account for up to 75% of feed costs (van der Klis & Kwakernaak, 2008). Therefore, more accurate evaluation of feed energy in broiler production is imperative for environmental and financial reasons. The metabolisable energy (ME) system is currently the preferred measure for determining energy utilis ...
