preparation example Construction
[0027] A preparation method of the functional feed, comprising the steps of:
[0028] (1) Preparation of matrix feed;
[0029] The protein feed, energy feed, minerals and vitamins used as raw materials are respectively crushed, mixed evenly, and mechanically pressed to form granules;
[0030] Among them, the particle size of the crushed raw materials should be above 40 mesh; uniform mixing means that various raw materials need to be fully stirred when mixing, and the coefficient of variation should not be greater than 7%; the diameter of the particles is 2 to 4 mm, and the length is the diameter of 1.5 to 2 times;
[0031] (2) The addition of additives;
[0032] The feed additive is mixed and prepared in advance, and then uniformly added to the matrix feed; or added to the matrix feed one by one by mass.
[0033] The functional feed is applied to the breeding of three-element hybrid fattening pigs.
