Floating feeds are more digestible as a product of the cooking process & the heat and pressure deactivate destructive enzymes as well. Beef heart has traditionally been used both as a source of protein, & as an effective binder in farm-made feeds. the feedstuffs, placing the answer in the opposite corner from the feedstuff. One must remember to reserve room in the formulation for any feed additive, such as a vitamin or mineral pre-mix. Thiaminase, an enzyme that destroys thiamine, is regularly found in freshwater fish. The square method is an easy way to determine the proper dietary proportions of high and low protein feedstuffs to add to a feed to meet the dietary requirement of the animal to be fed. Feed formulation and preparation is the processes of combining feed ingredients to form a mixture that will meet the exact goals of production.

They can be used to formulate feed for any type of livestock; poultry, cattle, goat, sheep, rabbit, etc. Feed formulation is the major part of aquaculture.The main objective of feed formulation is to utilize the knowledge of nutrient requirements, locally available feed ingredients and digestive capacity of fish for the development of a nutritionally balanced mixture of feed stuff… Purchase of raw materials must confirm adequate quality, traceability, environmental sustainability & safety standards.

The variety and quantity of vitamins and minerals are so complex that they are generally prepared synthetically and are available commercially as a  balanced and premeasured mixture called as a vitamin or mineral premix. Feed formulation is the procedure of quantifying the proportion of ingredients to be put together, to form a single uniform mixture or pellets that will provide all the nutritional requirements of the target fish. Feedingstuffs beginning, processing, handling & storage, as well as several other factors related to the market, can affect at different levels both quality and safety of feed.
