How to store feed pellet
During the rainy season, the air humidity is relatively high. If the feed is not stored properly, it is easy to become moldy and deteriorate. Various nutrients in the moldy feed are destroyed, the nutritional quality of the feed decreases, and even its utilization value is completely lost. After livestock and poultry eat moldy and rotten feed, toxins will accumulate in the animal's body, causing ...

How to choose a high quality fish feed pellet machine
Compared to ordinary complete formula feed pellets, extruded feed pellets have the following advantages: The quality of feed is improved. Because protein is combined with starch matrix, it is not easy to lose when feeding. Only when the digestive enzyme decomposes starch, can it release the protein and improve the protein potency. Secondly, the extrusion combines fat and starch into a composite ...
