Problems solved by technology

As the country imposes restrictions on the amount of zinc oxide, the amount of zinc added to weaned piglet feed is not allowed to exceed 1600ppm (calculated as zinc), and the problem of piglet diarrhea has become a huge challenge for formulators

preparation example Construction

[0031] In addition, the present application also provides a preparation method of the above-mentioned feed additive, which may include the following steps: mixing raw materials according to the ratio to obtain a mixture, spraying water in the mixture and granulating to obtain a granular zinc oxide-embedded auxiliary material First material; followed by drying, shaping and screening operations.

[0032] In some embodiments, prior to mixing, each raw material may be pulverized into a powder and then batched.

[0033] For reference, when batching, put each raw material into a stirring device (the material is preferably stainless steel) according to the ratio through the feeding port, and then stir for 8-10 minutes to mix the raw materials evenly to obtain a uniform powdery mixture.

[0034] Further, spray water into the mixture to obtain a wet mixture; preferably, spray water into the mixture while stirring the mixture. In some embodiments, the amount of sprayed water can be 20-...

Embodiment 1

[0047] This embodiment provides a feed additive for weaned piglets. In parts by weight, every 100 parts by weight of the above-mentioned feed additive for weaned piglets contains 60 parts by weight of zinc oxide and auxiliary materials. The auxiliary materials include 10 parts by weight of oil, 20 parts by weight of Starch, the binding agent of 5 parts by weight and the disintegrant of 5 parts by weight.

[0048] Wherein, the fat is sorbitan monooleate, the starch is cornstarch, the binder is guar gum, and the disintegrant is microcrystalline cellulose. The zinc oxide embedding rate of the auxiliary materials in the feed additive for weaned piglets is 70%.

Embodiment 2

[0050] This embodiment provides a feed additive for weaned piglets. In parts by weight, every 100 parts by weight of the raw material for feed additives for weaned piglets contains 70 parts by weight of zinc oxide and auxiliary materials. The auxiliary materials include 1 part by weight of fat, 10 parts by weight starch, 10 parts by weight of binder and 9 parts by weight of disintegrant.

[0051] Wherein, the fat is sorbitan monostearate, the starch is sweet potato starch, the binder is xanthan gum, and the disintegrating agent is calcium stearate. The zinc oxide embedding rate of the auxiliary materials in the feed additive for weaned piglets is 70%.

Abstract

The present invention relates to a feed additive for weaned piglets, a preparation method and an application thereof, and belongs to the field of feeds. The feed additive for the weaned piglets comprises the following raw materials of zinc oxide, oil, starch, a binder, and a disintegrant. In the feed additive for the weaned piglets, the zinc oxide is embedded with the auxiliary materials and an embedding rate is 70-80%. The additive can achieve the same anti-diarrhea effect as the prior art, at the same time greatly reduces use amount of the zinc oxide, achieves harm reduction and emission reduction, and can also solve a problem of feed palatability. The preparation method comprises the following steps: raw material mixing according to a ratio, then water spraying and granulating, and thendrying, shaping and sieving. The method is simple and rapid, good in condition controllability, and can enable the auxiliary materials to effectively embed the zinc oxide and control the embedding rate to a better range. The additive is added into a basic daily diet of the weaned piglets, can reduce diarrhea rate of the piglets, improves hair color of the piglets, at the same time is free of other zinc sources, and can meet nutritional needs of the piglets.

Description

technical field [0001] The invention relates to the field of feed, and in particular to a feed additive for weaned piglets and a preparation method and application thereof. Background technique [0002] When piglets are weaned, they are prone to diarrhea. To achieve a better effect of preventing and controlling diarrhea, the addition amount of ordinary zinc oxide needs to be more than 2000ppm (calculated as zinc). As the country imposes restrictions on the amount of zinc oxide, the amount of zinc added to weaned piglet feed is not allowed to exceed 1600ppm (calculated as zinc), and the problem of piglet diarrhea has become a huge challenge for formulators. Contents of the invention [0003] The purpose of the present invention is to provide a feed additive for weaned piglets, which can not only achieve the same anti-diarrhea effect compared with the prior art, but also greatly reduce the amount of zinc oxide, realize harm reduction and emission reduction, and can also solv...
