Problems solved by technology

[0004] According to the above technical scheme, it can be seen that the premix provided by this patent adopts the structure of conventional core material plus wall material, and the material of the wall material is selected from maltodextrin, trehalose, and casein. The resistance of these wall materials is The grinding strength and acid resistance are low, and it is easy to rupture in the esophagus and stomach environment, exposing the core material in advance, causing the core material to be decomposed by gastric acid, thus greatly reducing the absorption of the core material by the intestinal tract

preparation example Construction

[0016] The specific embodiment provides a preparation method of a special feed additive for sows, comprising the following steps:

[0017] S1. The core material is obtained by dry granulation of phosphorus agent, calcium agent and trace element supplement;

[0018] S2, the papaya seed gum and gluten are mixed to obtain the inner wall material, and the inner wall material is coated to the outside of the core material obtained in step S1 by a coating machine, to obtain an intermediate;

[0019] S3. Coating the soybean protein isolate to the outside of the intermediate obtained in step S2 by a coating machine, to obtain a special feed additive for sows.

[0020] Further, in terms of mass ratio, core material: inner wall material: soybean protein isolate=1:0.3:0.5.

[0021] Further, in step S1, the phosphorus agent is sodium dihydrogen phosphate or bone meal, and the calcium agent is calcium iodate.

[0022] Further, the trace element supplement is one or more of copper sulfate,...

Embodiment 1

[0039] The present embodiment is used to prepare a special feed additive for sows, and the preparation method includes the following steps:

[0040] S1. The core material is obtained by dry granulation of sodium dihydrogen phosphate, calcium iodate and copper sulfate in a mass ratio of 1:1.5:1.5;

[0041] S2, preparation of intermediates

Abstract

The invention relates to the technical field of feed, and provides a special feed additive for sows and a preparation method thereof, and the preparation method comprises the following steps: S1, carrying out dry granulation on a phosphorus agent and a calcium agent to obtain a core material; s2, mixing papaya seed gum with vital gluten to obtain an inner wall material, and coating the inner wall material to the outside of the core material obtained in the step S1 through a coating machine to obtain an intermediate; and S3, coating the soybean protein isolate to the outside of the intermediate obtained in the step S2 through a coating machine to obtain the special feed additive for the sows. The special feed additive for sows provided by the invention can effectively slow down abrasion in esophagus and slow down corrosion in stomach environment, and can safely and completely feed phosphorus and calcium into intestinal tracts of sows.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a special feed additive for sows and a preparation method thereof. Background technique [0002] Sow production paralysis, also known as sow paralysis, including prenatal paralysis and postpartum paralysis, is a disease characterized by muscle relaxation of limbs and low blood calcium in sows before and after birth. The main reason is nutritional disorders such as calcium and phosphorus. The reason for the decrease in blood calcium may be related to the following factors: a large amount of blood calcium enters the colostrum before and after childbirth, and the calcium lost in the blood cannot be replenished quickly, resulting in a sharp drop in blood calcium; in the late pregnancy, calcium intake is seriously insufficient; Calcium and intestinal absorption decrease; improper or lack of calcium and phosphorus ratio in feed, vitamin D deficiency, low magnesium diet can accelerate the...
