In a new joint research from Texas A&M University and AB Vista, researchers have found that high doses of phytase, used to correct the lack of essential phytate, also help to correct amino acid deficiencies in broiler chickens. slow

This study showed its effects on poultry body weight, breast meat yield, and feed conversion ratio of Cobb broilers during 44 days. Dr. Craig Wyatt, technical director of the North American branch, says about this experience:
"In the competitive environment of poultry production, producers are trying to increase their efficiency and profit. Reducing the amount of digestible amino acids in the diet of poultry, while lowering the cost, also leads to a decrease in efficiency and a decrease in their body weight. So we conducted a study to see if adding high doses of phytase would help reduce feed costs - because it would help the producer increase the amount of digestible amino acids in the feed without reducing yield and performance traits. Poultry food diet lowered."
This test was performed with AB Vista Quantum Blue phytase at three levels of 500, 1,500 and 3,000 FTU/Kg as well as 3 levels of digestible amino acids as follows: the control group with the same level of 100% recommended, and the following groups respectively with 95% and 90% percent.
  The results confirmed that as the level of digestible amino acids decreases, the efficiency also decreases; Following the reduction in the two groups, the feed conversion factor increased by 3.1 units and resulted in a 78-gram decrease in total body weight and a 27-gram decrease in breast meat yield.
But on the contrary, the increase of phytase led to the improvement of yield and performance; Increasing the dose of phytase resulted in weight gain on the 18th day; However, 3000 FTU/Kg of phytase was required to see a significant weight gain on day 44.
In the same way, increasing the dose of phytase in the initial phase led to the improvement of the feed conversion ratio, but FTU/Kg of 3000 units of phytase was needed to reduce the feed conversion ratio in the final phase and from the first day to the 44th day. Regarding the yield of breast meat, FTU/Kg 1,500 phytase units was more suitable than FTU/Kg 500 phytase units.
In the end, Dr. Wyatt concludes as follows:
"On diets low in digestible amino acids, there is a clear correlation between increased phytase and improved performance, which is of interest to any producer. We are continuing to develop and advance our studies into how phytase is related to performance. and discover more digestible amino acids than before."
