preparation example Construction
[0047] Its preparation method comprises the following steps:
[0048] 1), raw material pretreatment,
[0049] First, weigh 1% to 5% of corn oil and 2% to 6% of anhydrous milk fat, heat the corn oil and anhydrous milk fat to 70-80°C to melt, add 3% to 10% of the total weight of raw materials in water, and stir well , in a semi-fluid state; stand-by;
[0050] Weigh raw materials according to the proportion: casein, corn starch, maltodextrin, sucrose, cellulose, DL-methionine, D-galactose, complex minerals, calcium carbonate, multivitamins and choline bitartrate;
[0051] 2), prepare the mixture,
[0052] Mix the weighed raw materials, stir evenly, add the above semi-fluid fat, and continue mixing for 2 to 4 minutes;
[0053] 3), prepare the product,
[0054] At 20-30°C, feed pellets with a diameter of 10mm and a length of 15-20mm are produced by a ring die pellet machine; at 20-25°C, the feed pellets are dehumidified and dried for 24-36 hours through a dehumidifier, and fina...

[0058] 1), raw material pretreatment,
[0059] First, weigh the materials in the raw materials: 1% corn oil, 2% anhydrous milk fat, heat the corn oil and anhydrous milk fat to 70°C to melt, add the total weight of the raw materials to the heated and melted corn oil and anhydrous milk fat mixture 3% water, stir evenly to form a semi-fluid fat material; set aside;
[0060] Weigh other materials in raw materials according to the proportion: 20% casein, 15% corn starch, 10% maltodextrin, 20% sucrose, 5% cellulose, 0.1% DL-methionine, 0.02% D-galactose, compound mineral Substance 0.5%, calcium carbonate 0.1%, multivitamin 0.5% and choline bitartrate 0.2%;
[0061] 2), prepare the mixture,
[0062] Mix the weighed raw materials, stir evenly, add the above semi-fluid fat, and continue mixing for 2 to 4 minutes;
[0063] 3), prepare the product,
[0064] At 20-30°C, feed pellets with a diameter of 10mm and a length of 15-20mm are produced by a ring die pellet machine; at 20-25°C, ...

[0068] 1), raw material pretreatment,
[0069] First, weigh the materials in the raw materials: 3% corn oil, 4% anhydrous milk fat, heat the corn oil and anhydrous milk fat to 75°C to melt, add the total weight of the raw materials to the heated and melted corn oil and anhydrous milk fat mixture 6.5% water, stir evenly to form a semi-fluid fat; set aside;
[0070] Weigh other materials in raw materials according to the proportion: 25% casein, 22.5% corn starch, 15% maltodextrin, 25% sucrose, 7.5% cellulose, 0.3% DL-methionine, 0.06% D-galactose, compound mineral Substance 2%, calcium carbonate 0.3%, multivitamin 1.75% and choline bitartrate 0.6%;
[0071] 2), prepare the mixture,
[0072] Mix the weighed raw materials, stir evenly, add the above semi-fluid fat, and continue mixing for 2 to 4 minutes;
[0073] 3), prepare the product,
[0074] At 20-30°C, feed pellets with a diameter of 10mm and a length of 15-20mm are produced by a ring die pellet machine; at 20-25°C, the ...
