Excellent Fish Food FormulaBefore designing fish feed pellet formulation, we should make certain the species and growth stage of fish to determine the content ofnutrients including protein, energy and so on. The fish feed pellet formulation should not only meet the fish’s demand for protein, but alsohave a reasonable proportion of energy to protein, because too high or two low proportion of energy to protein will be bad for the growthof fish. In addition to nutrition, satiety of fish should be also taken into consideration when formulating fish feed pellet.Choose Suitable Raw MaterialsChoosing raw materials for fish feed pellet shoud be based on three principles: quality and cheap, stable source and convenient transportation.When conditions allow, the more the kinds of materials are, the better the feed pellets will be. In this way, the essential amino-acid in thefeed can achieve a balance and satisfy the fish’s demand for amino-acid to the greatest extent. On the other hand, the moldy and spoiledmateirals can easily cause fish disease, so they mustn’t be used for feed. Materials like cottonseed cake and rape seed cake should also belimited to 10% in feed because they contain anti-nutritional factors such as gossypol and glucose thioglycoside which will affect the fishgrowth if used in large amount. Many farmers like to use cheap greaves and meat cake to make fish feed pellets, but this kind of materialsusually mixed with a lot of animal fur and feather which will impact the grinding and pelletizing process and cause digesting problem of fish.Last but not least, the moisture content of mateirals should be about 12%-13% after drying. Too high moisture content will reduce the nutritive value of feed pellets, cause mould and reduce the storage time.
Control Fish Feed Pellet Processing TechnicThe process of making your own fish feed pellet generally includes grinding,mixing,pelletizing, sometimes conditioning.Grinding can increase the contact area between feed and animal digestive enzyme, improve the digestive absorption of substance, nitrogen andenergy and reduce the feed coefficient. Generally, the materials for fish feed pellet should all pass through the 40 mesh sieve and not more than20% left on the 60 mesh sieve. For making carp fish feed pellet, the optimal grinding fineness is 1.7mm.Mixing is an important part to ensure compound fish feed pellet quality. Uneven mixing will lead to uneven distribution of variety nutrients in thefish feed pellets and then affected greatly the fish growth, even cause death of fish in severe cases. Here we can adopt fish feed mixer to get thebest mixing result.Conditioning is a process where the hot steam is injected into the conditioner of fish feed extruder and then feedstuff is subject to mixing and heatingunder hot steam before being forced through a die mould. In this way, materials have fully gelatinization of starch by a combination of hot steamand mechanical shear/mixing.Now we all know the benefits of their own fish feed pellet.
