Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with specific examples, but not as a limitation of the present invention. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0028] The following raw materials were weighed according to the following proportions: 90.5 g of corn flour, 2.0 g of sucrose, 45.2 g of calcium chloride, 25.1 g of calcium sulfate, 39.2 g of ammonium chloride, 8.0 g of ammonium sulfate, and 2.0 g of magnesium oxide. Among them, corn flour is obtained by crushing corn through a 0.1-0.5 mm mesh grinder after cleaning impurities and magnetic separation to remove iron; calcium chloride, calcium sulfate, ammonium chloride, ammonium sulfate and magnesium oxide are crushed to a particle size of ≤0.5 mm.

Abstract

The invention discloses a gelatinized anionic salt additive special for cows at early perinatal period and a preparation method thereof. The additive is composed of the following components by weight: 35-40 parts of corn flour, 0.5-1.0 part of sucrose, 15-20 parts of calcium chloride, 10-15 parts of calcium sulfate, 15-20 parts of ammonium chloride, 3-5 parts of ammonium sulfate, 0.5-1 part of magnesium oxide, and 8-10 parts of rumen-protected choline, wherein the calcium chloride, calcium sulfate, ammonium chloride, ammonium sulfate and magnesium oxide are gelatinized by corn flour and are then coated. Without affecting or lowering the dry matter intake of cows, the gelatinized anionic salt additive provided by the invention can effectively control postnatal hypocalcemia and other metabolic diseases caused by the content decrease of blood calcium in blood after cow labor onset and lactation, improve lipid metabolism, strengthen immunity, and relieve negative energy balance.

Description

technical field [0001] The invention relates to the technical field of livestock additives, in particular to a special gelatinized anion salt additive for dairy cows in the peripartum period and a preparation method thereof. Background technique [0002] The perinatal period of dairy cows refers to the period of 3 weeks before the cows give birth, including the end of dry milk and the delivery period. During this period, dairy cows undergo complex physiological changes in many aspects such as rumen function, ovarian function, endocrine and metabolism. With the continuous development of the fetus and the increase in the nutrient requirements of the mammary gland, after entering the perinatal period, the dry matter intake of dairy cows continues to decrease, and due to the needs of lactation, the levels of blood calcium, vitamins and trace elements in dairy cows decrease, resulting in dairy cows Negative energy balance, hypocalcemia, decreased immunity. Therefore, this stage...
