The rocky relationship between limestone solubility and phytase efficacy

poultry

It is well known that limestone is used as a major source of inorganic calcium (Ca) in commercial poultry diets, as well as microbial phytase to improve phosphorus (P) and Ca utilisation, and to reduce P excretion into the environment.  The efficacy of commercial microbial phytase to degrade phytate (myo-inositol hexakisphosphate, or IP6) in the…

The catalyst you need to jumpstart your production system

Making sense of the wide variety of commercially available phytase products can be a daunting prospect. This can often lead to a poultry producer feeling confused and frustrated. That is why we at Chemuniqué believe that the only way to separate the best from the pretenders is with scientifically supported evidence. An example of such…

The benefits of measuring calcium digestibility from raw materials in poultry

limestone variation

Abstract To date, poultry diets have been formulated to meet estimated requirements for total calcium (Ca), while frequently also maintaining a specified ratio of total Ca to available phosphorus (AvP). In vegetable-based diets, limestone can contribute in excess of 50% and 90% of dietary Ca in broiler and layer diets, respectively. In laying hens, it…

Making the most of phytase

phytase

Chemuniqué’s enzyme partner, DuPont Animal Nutrition, recently released a new white paper on the effective use of phytase matrix values in feed formulations and the significant positive impact it has on improving performance, reducing feed costs, and boosting production efficiencies. They examine the latest research to further explore the use of full matrix values with…
