Feed for cage-reared laying ducks in high-temperature seasons and preparation method thereof
By developing a feed formula with a metabolizable energy of 2400 kcal/kg and a crude protein content of 18%, the nutritional imbalance problem of caged laying ducks during the high-temperature season was solved, improving production performance and feed utilization, and reducing breeding costs.

AI Technical Summary
The existing formulas for caged laying duck feed lack scientific guidance, resulting in an unreasonable ratio of energy and protein, which leads to the underutilization of the laying ducks' production performance, serious waste of feed resources, and the existing standards are not applicable to the physiological needs of high-temperature seasons.
By studying and determining the precise energy and protein requirements of caged laying ducks, a feed formula with a metabolizable energy of 2400 kcal/kg and a crude protein content of 18% was prepared. The formula includes components such as corn, rice bran meal, soybean meal, limestone powder, and dicalcium phosphate, combined with compound trace elements and vitamins. The preparation method includes premixing and pelleting processes.
It achieves a precise match between nutritional supply and high-temperature physiological needs, alleviates heat stress, improves egg production performance, increases feed utilization, reduces breeding costs, adapts to cage rearing mode, and solves the problems of nutritional imbalance and declining production performance.
