Embodiment 1

[0018] A method for preparing an anionic salt feed additive in the perinatal period of dairy cows, comprising the steps of:

[0019] (1) Preparation of semi-finished products: sieve DDGS and bran, which are grain carrier raw materials with strong acidity, with a 60-mesh sieve, and save the under-sieve for later use; dilute food-grade hydrochloric acid with distilled water at a volume ratio of 1:2 Seal and store for later use; mix and stir the diluted food-grade hydrochloric acid solution and the sieved DDGS at a ratio of 1mL: 2g, and mix and stir with the sieved bran at a ratio of 1mL: 1.5g to obtain a mixture; Low-temperature fluidized bed process for drying treatment to obtain semi-finished products;

[0020] (2) Preparation of coated calcium chloride: weigh 7.4 grams of anhydrous calcium chloride at room temperature and add 10 ml of distilled water to stir and dissolve, i.e. calcium chloride saturated solution; add mass percentage 14.0% to 22.0% in calcium chloride saturate...

Embodiment 2

[0023] A method for preparing an anionic salt feed additive in the perinatal period of dairy cows, comprising the steps of:

[0024] (1) Preparation of semi-finished products: Sieve puffed soybeans and bran, which are grain carrier raw materials with strong acidity, with a 60-mesh sieve, and take the under-sieve for future use; dilute food-grade hydrochloric acid with distilled water at a volume ratio of 1:2 Seal and store for later use, mix and stir the diluted food-grade hydrochloric acid solution and the sieved bran at a ratio of 1mL: 1.5g, dilute food-grade hydrochloric acid and distilled water at a volume ratio of 1:3, seal and store for later use, and The diluted food-grade hydrochloric acid solution and the sieved puffed soybeans are mixed and stirred at a ratio of 1mL: 2g to obtain a mixture; the mixture is dried by a low-temperature fluidized bed process at 40-50°C to obtain a semi-finished product;

[0025] (2) Preparation of coated calcium chloride: weigh 7.4 grams ...

Embodiment 3

[0028] A method for preparing an anionic salt feed additive in the perinatal period of dairy cows, comprising the steps of:

[0029] (1) Preparation of semi-finished products: sieve bran, which is a grain carrier raw material with strong acidity, with a 60-mesh sieve, and take the under-sieve and save it for later use; dilute food-grade hydrochloric acid with distilled water by volume 1:2, seal it and save it for later use , mixing and stirring the diluted food-grade hydrochloric acid solution and the sieved bran at a ratio of 1mL: 1.5g to obtain the mixture; using a low-temperature fluidized bed process at 40 to 50°C for drying treatment to obtain a semi-finished product;

[0030] (2) Preparation of coated calcium chloride: weigh 7.4 grams of anhydrous calcium chloride at room temperature and add 10 ml of distilled water to stir and dissolve, i.e. calcium chloride saturated solution; add mass percentage 14.0% to 22.0% in calcium chloride saturated solution beet molasses, stir...

Abstract

An anionic salt feed additive for dairy cattle in the perinatal period is prepared from a cereal carrier, food-grade hydrochloric acid and coated calcium chloride, wherein the mixing proportion of food-grade hydrochloric acid which is diluted in different proportions to the cereal carrier is 1 mL:2 g or 1 mL:1.5 g, and coated calcium chloride is coated with molasses or silicon dioxide. The anionic salt feed additive for dairy cattle in the perinatal period and the preparation method thereof have the advantages that the defect that liquid hydrochloric acid is likely to generate a toxic and corrosive smell is overcome, the defect that calcium chloride is likely to deliquesce after absorbing moisture is overcome, and meanwhile the problem that calcium chloride is poor in palatability is solved; besides, by adding the product appropriately, diseases in the perinatal period can be controlled and prevented; meanwhile, the process is easy to implement, the product is good in stability, the cost is low, and application and popularization are easy.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to an anionic salt feed additive in the perinatal period of dairy cows and a preparation method thereof. Background technique [0002] Anionic salts are a class of mineral salts that are high in anions such as chlorine and sulfur and low in cations such as sodium and potassium. Adding an appropriate amount of anionic salt to the diet of dairy cows in the late pregnancy has a good effect on controlling and preventing perinatal diseases such as milk fever, hypocalcemia, retained placenta, ketosis, udder edema, and abomasum displacement. [0003] Dietary anion-cation balance (DCAD) or anion-cation difference (CAD) refers to the main cation (Na + 、K + , Ca 2+ , Mg 2+ ) and the main anion (Cl - , S 2- 、PO4 3- ) content and the difference between the number of millimoles. When DCAD is positive, it is called cationic diet, and when it is negative, it is called anionic diet...
