In animal feed, it is very important to take care of the protein intake. One way to supply them is by using fishmeal . This flour is made by grinding and drying whole fish or good quality fish remains discarded by the processing industry. Once shredded, the fish is cooked at a minimum of 100º. It is then pressed and centrifuged to remove oils. Lastly, it dries, to remove as much moisture as possible.

Given its interest in animal feed, the demand for this product has grown notably in recent years. The expansion of aquaculture has contributed to the consolidation of this industry. It finds in it a constant source of good quality raw material. Thus, according to FAO data, world flour production has gone from about 120 million tons by the year 2000 to more than 160 million tons by 2016.

What fish is the flour made of

To produce that amount of flour, very diverse pelagic species are used, but, above all, species that man does not consume, such as anchovy. Others are common in human food, such as horse mackerel or mackerel and sardines. However, these are very abundant species and of relatively low economic value.

Generally, blue fish , rich in fat, is used. However, a percentage of the flour is produced from white fish waste, such as hake or cod, as long as its oil content is low.

Benefits of animal consumption of fish

For animals, fishmeal is a very valuable nutrient . It provides them with a large concentration of high-quality proteins . In addition, being made with fish rich in fat, it also provides omega-3 acids, DHA and EP.

Thanks to proteins (especially tryptophan, lysine or cysteine), animals develop their bodies better (especially muscle tissues). They are also raised stronger, more agile and healthier . On the other hand, healthy fats contribute to the animal having a better general state of health. With clear benefits on blood circulation and cardiac toning.

Finally, fishmeal is a source of minerals . It is especially rich in phosphorus and also contains calcium and high levels of vitamins (especially A, B, B12 and D). Therefore, it constitutes a balanced and energy-efficient food for animals.

With these qualities, it is easily explained how widespread its use is in the breeding of all types of animals. For example, in dairy cows herds, it contributes to increasing milk production by up to two liters per day per cow. In addition to improving its protein content. In the case of sheep , it has been shown to improve their fertility; whereas, in pigs, it stimulates their growth.

Therefore, with fishmeal we are faced with a fundamental ingredient to balance and enrich the diets of animals, both those raised for food production and in the case of companion animals.
