A study was conducted to investigate the hypothesis that over-processing (OP) of meat and bone meal (MBM) exacerbates infection with necrotic enteritis in normal and high phytase diets. A total of 768 Ross 308 male chicks were randomly assigned to 8 treatments with 6 replicate floor pens each housing 16 chicks using a 2 × 2 × 2 factorial arrangement of treatments for 42 d. Factors were ...

Phytate is a polyanionic molecule with the capacity to chelate Ca, forming mineral-phytate complexes. The presence of these complexes decreases the efficacy of phytase. Ca-phytate formation is dictated by molar ratios of the constituents, gastrointestinal pH and the concentration of dietary Ca relative to P (Sommerfeld et al., 2018). The hypothesis of this study was that a high dietary Ca to P rat ...

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 ...

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 ...

Copper (Cu) is an essential component involved in a wide variety of biochemical processes. It must be supplemented in the trace mineral premix as the amount present in raw materials is inadequate to meet broiler requirements. At levels higher than nutritional requirements (up to 250 mg/kg), dietary Cu addition enhances growth performance by altering gut microbiota and enhancing nutrient absorption ...

Audrey McElroy Check out for a literature review we are publishing with World's Poultry Science Journal. We are now doing the proofreading. I have proposed possible research topics in there. I can be reached at firstname.lastname@example.org. Thanks.

I find this work very interesting. I have just published a series of papers on this same work in Poultry Science. The overall outcomes are similar to what I found in my work. Can we do something further to this?
