Since self-prepared fish feed can make full use of agricultural and sideline products and reduce feed costs, as the price of feed commodities rises, many breeding farmers have begun to produce self-prepared 鱼饲料. However, many breeding farmers lack the knowledge of fish nutrition and feed. There are many misunderstandings in the production of self-prepared fish feed. Such as some breeding farmers are pursuing high protein one-sidedly, and some are pursuing low-cost one-sidedly while ignoring the fish requirements for nutrition. The demand for nutrition has resulted in increased feed costs. To produce high-quality and efficient self-prepared fish feed, the following aspects must be considered.
合理设计饲料配方
Before designing a 鱼饲料配方, it is necessary to understand the type and growth stage of the farmed fish to determine the level of nutrients such as protein and energy in the feed. The fish feed formula must not only meet the needs of fish for protein growth but also make the ratio of energy and protein moderate. Both too high and too low energy-to-protein ratio is not conducive to fish growth.
在设计鱼饲料配方时，还要考虑营养水分与饲料容重之间的关系。还要保证鱼类摄入的营养不足，并使其有饱腹感。鱼类主要以蛋白质作为能量来源，而脂肪和碳水化合物的利用率较低。因此，鱼类对蛋白质的需求高于畜禽。鱼类生长的不同阶段对各种营养素的需求也不同。例如，鲤鱼幼鱼饲料的蛋白质含量为43%-41%，小鱼为37%-42%，成鱼为28%-32%。
鱼饲料原料的选择
When selecting feed ingredients, the principles of high quality and low price, stable supply, and convenient transportation should be followed. When conditions permit, the more types of raw materials, the better, so that the necessary amino acids in the feed can be balanced as much as possible.
最大限度地满足鱼类对各种必需氨基酸的需求。发霉的原料含有大量细菌和毒素。例如，发霉的玉米含有剧毒的黄曲霉毒素。这些饲料喂食后很容易引起鱼类疾病。
虽然棉籽饼和菜籽饼等原料价格便宜且蛋白质含量高，但它们分别含有棉酚和硫代葡萄糖苷等抗营养因子，过量喂食会影响鱼类的生长。
因此，限制其用量，一般不超过10%。许多养殖户喜欢使用廉价的油渣和肉饼，但这些原料混有大量的动物皮，影响了粉碎和制粒工艺的顺利进行，鱼类食用后不易消化。
油渣和肉饼中含有的脂肪是饱和脂肪，长期储存会发生酸败。鱼类对饱和脂肪的利用率低，摄入过多的酸败脂肪也会导致鱼类患脂肪肝等疾病。
因此，此类原料的用量应控制在5%以下。此外，在选择原料时还应注意原料的含水量。过高的水分会降低鱼饲料的营养价值，还可能导致饲料发霉，缩短饲料的储存时间。
鱼饲料加工工艺的控制
该 process of producing self-prepared feed generally includes crushing, mixing, fish feed pellet machine, and conditioning. The machines used in the process include a grinder, mixer, fish feed pellet mill machine, or fish feed mill machine.
粉碎机粉碎的原料可以增加饲料与动物消化酶的接触面积。提高了物质、氮和能量的消化吸收率，降低了饲料系数。粉碎粒度过粗或过细都不好。
鲤鱼鱼种饲料的最佳粉碎粒度为177цm。鲤鱼幼鱼配合饲料的粉碎粒度为0.30-0.25mm。混合是保证混合饲料质量和提高饲喂效果的主要环节。
饲喂实践表明，如果原料中的成分混合不均匀，会影响鱼类的生长。严重时会导致死亡。这是因为混合不均匀导致饲料中各种营养物质的分布不均。达不到配方的效果，某些添加剂如重金属局部浓度过高会导致鱼类中毒死亡。
我们生产的混合机包含混合钢条，可以充分混合各种饲料成分。从而避免上述问题。同时，这也是机器生产的鱼饲料和人工鱼饲料的优点。
如何通过鱼饲料加工机加工鱼饲料？
通过以上对加工业的控制，我们将粉碎和搅拌后的自配饲料倒入鱼饲料挤出机。然后通过调整机器来调整生产速度和形状。通过这种鱼饲料挤出机，您可以生产漂浮鱼饲料或沉性鱼饲料。
