[0046] A preparation process for dairy cow dry milk peripartum concentrate supplement, comprising the following steps:
[0047] S1. Feeding: Prepare protein-based raw materials, energy-based raw materials, yeast-like substances, vitamin E, organic selenium, vitamin A, anion salts, calcium raw materials, trace elements, by-products and other materials for use;
[0048] S2, iron removal: the raw material in step S1 is removed iron through the permanent magnetic cylinder;
[0049] S3. Cleaning: pass the iron-removed material through a 12mm cleaning sieve for cleaning and impurity removal;
[0050] S4, pulverization: the material after above-mentioned cleaning is put into pulverizer and pulverizes, and the sieve sheet of pulverizing sieve is 4.0mm;
[0051] S5. Ingredients: 20-30% of protein-based raw materials, 10-15% of energy-based raw materials, 3-5% of yeast substances, 0.15-0.3% of vitamin E, 0.07-0.2% of organic selenium, and 0.008-0.02% of vitamin A %, 0.4-4.5% of anion ...

Abstract
The invention discloses a dairy cow dry milk perinatal period concentrate supplement, which comprises the following raw materials by mass: 20-30% of a protein type raw material, 10-15% of an energy type raw material, 3-5% of a yeast substance, 0.15-0.3% of vitamin E, 0.07-0.2% of organic selenium, 0.008-0.02% of vitamin A, 0.4-4.5% of an anionic salt, 0.8-1.5% of a calciumraw material, 0.7-2% of trace elements, 40-60% of a by-product, and 5.5-15% of other substances. By adopting the concentrate supplement for dairy cows in the dry milk perinatal period, the incidence rate of postpartum ketosis of the dairy cows is reduced, the dry matter feed intake and the postpartum lactation yield are improved, and the problem that the granularity of TMR daily ration of dry milk perinatal cattle is difficult to control is solved.
Description
technical field [0001] The invention relates to the technical field of feed, in particular to a dairy cow dry milk perinatal concentrate supplement and a preparation process thereof. Background technique [0002] Only when the new milk cows are healthy and productive can the overall production performance of the dairy farm be improved. In recent years, the management level and production performance of dairy farms have been increasing year by year, and the means and intensity of health monitoring for new dairy cows have also been continuously strengthened. Dairy farms have found that there are great risks and hidden dangers to the health of new dairy cows. In particular, the incidence of diseases such as ketosis is increasing year by year, and the incidence of ketosis in new milk cows in some dairy farms has reached more than 50%. However, after new cows get ketosis, the dry matter intake and body condition of dairy cows will drop rapidly, which will lead to low milk produ...
