The compound feed for laying hens during the laying period is formulated scientifically, providing comprehensive and balanced nutrition with high-quality and stable raw materials. The product features a balanced ratio of protein and energy, as well as a reasonable design and balanced ratio of essential amino acids and trace elements, fully meeting the normal growth and production needs of laying hens. The feed has a balanced ratio of calcium and phosphorus, resulting in good egg shell color and high egg shell hardness. When using Hao Duobang 324 throughout the entire process, laying hens exhibit a long peak laying period, high laying rate, large egg size, low mortality and culling rate, and a low feed-to-egg ratio. The cumulative egg production per hen can reach 19-21 kilograms, which is 3-5 kilograms more than hens fed with ordinary compound feed for laying hens.
