I request to try the same with natural vegetable or herbal products, which contain the organic acids like for citric acid Lemon or Indian goose berry (Amla fruit), by which the results will be positive.
Dear Ebrahim
Looking to this trail is very difficult to draw a final conclusion about advantage of using organic acid in broiler production.
What I personally learned is the surprising low level of energy and protein in those feed formulations that anyway translate in higher feed conversation for those particular broilers.
In addition looks like your country is a soya/corn user (as main raw materials) for broiler production.
Best regards,
Viorel
