Application of organic chelated trace elements in the preparation of broiler feed additives

The application of organic chelated trace elements in the preparation of feed additives for broilers involves adding organic chelated trace elements to the basic diet of broilers. The organic chelated trace elements are copper, zinc, manganese, Iron, iodine, cobalt and selenium, among which, per kilogram of basic diet, the added amount of copper is 0.75~6.75mg, the added amount of zinc is 4.0~36.0mg, the added amount of manganese is 4.0~36.0mg, the added amount of iron The amount is 1.50~13.50mg, the added amount of iodine is 0.075~0.675mg, the added amount of cobalt is 0.025~1.225mg, and the added amount of selenium is 0.013~1.113mg. Compared with inorganic trace elements, adding appropriate levels of organic trace elements to corn and soybean meal diets can significantly improve the daily weight gain, feed utilization and body weight of broilers. At the same time, replacing high-dose inorganic trace elements with low-dose organic trace elements can also reduce the excretion of trace elements and reduce environmental pollution.

In the basic diet of broilers, organic copper, zinc, manganese, iron, iodine, cobalt and selenium are added. Compared with the existing technology, the types and dosages of organic trace elements are more optimized and perfected, and the unexpected technical effect of improving production performance is achieved while reducing the dosage.
Compared with inorganic trace elements, adding appropriate levels of organic trace elements to corn and soybean meal diets can significantly improve the daily weight gain, feed utilization and body weight of older broiler chickens. Add 25 to 35% organic trace elements (Cu 3.75 to 5.25 mg/kg, Zn 20.0 to 28.0 mg/kg, Mn 20.0 to 28.0 mg/kg, Fe 7.50 to 10.50 mg/kg, I0. 375～0.525mg/kg, Co 1.125～1.175mg/kg, Se 0.063～0.088mg/kg). By the age of 42 or 49 days, the body weight was significantly higher than that of the negative control group without adding trace elements, and even higher. In the control group with 100% inorganic trace elements added. At the same time, replacing high-dose inorganic trace elements with low-dose organic trace elements can also reduce the excretion of trace elements and reduce environmental pollution.
