Extruded Aquatic Feed Pellet Production Line

When formulating feed formulas, it is necessary to comprehensively consider the type of farmed fish, the growth stage, and the proportion of key nutrients such as protein and energy in the feed. It is necessary to ensure that fish obtain the necessary protein to support their growth, and to maintain the balance of energy and protein to avoid imbalance in the proportion that affects fish health. At the same time, it is also necessary to weigh the nutrition and capacity of the feed, to ensure that fish take in enough nutrition, and to avoid overeating. It is worth noting that protein feed is usually more expensive than energy feed. Therefore, in the preparation process, it should be avoided to increase the proportion of energy feed excessively to save costs, thereby reducing the proportion of protein feed, which may increase the overall feed cost.

When selecting feed raw materials, the principles of high quality, low price, stable supply and convenient transportation should be followed. In order to ensure the balance of amino acids in the feed and meet the needs of fish for various amino acids, the richer the raw materials, the better. At the same time, the use of moldy and spoiled raw materials must be avoided. Although cottonseed meal and rapeseed meal are affordable and high in protein, they contain anti-nutritional factors such as gossypol and glucosinolates that may affect fish growth, so their use should be limited, generally not exceeding 10%.
