Increasing levels of phytase past recommendations of the feed formula can improve the overall production performance of broiler chickens and consequently enhanced economic profitability. The findings of this new study are published in the International Journal of Poultry Science.
The plant-based poultry diet has a vital antinutrient factor, known as Phytate, that can limit the availability of important minerals and nutrients like phosphorus, proteins, and carbohydrates, to be absorbed by the chicken. Rendering their ability to digest phytate, their feed is enriched externally with phytase, an enzyme that helps with the digestion of phytate.
Previously, the addition of 500 FTU per kg phytase in corn-soybean based has been practiced, but since it is not enough to dephosphorylate the phytate, so scientists have tried phytase super dosing in feed to observe its effects on the performance, bone quality, and serum profile of broiler chickens.
the current study indicates that 500 and 1500 FTU phytase per kg of diet could improve overall performance and consequently increase the total profit per kg live bird.
The authors suggested that further research is needed to examine the effect of an increased dose of phytase on a marginally P-deficient diet.
