Concentrate supplement for dairy cows in perinatal later period and preparation method thereof

Abstract

The invention provides a concentrate supplement for dairy cows in a perinatal later period, containing 8% of premix and a preparation method thereof. Per ton of concentrate supplement comprises 80kg of premix in the perinatal later period, 326kg of corn, 40kg of rapeseed meal, 150kg of cottonseed meal, 150kg of wheat bran, 198kg of soybean meal, 26kg of fat powder, 20kg of baking soda and 10kg of magnesium oxide. The concentrate supplement has reasonable design of mixture ratio, is suitable for nutritional needs of the dairy cows in the perinatal later period, is convenient to purchase various component raw materials, convenient to use and easy to popularize, and has high practical values.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a post-perinatal concentrate supplement for dairy cows containing 8% premix and a preparation method thereof. Background technique [0002] In recent years, the output of dairy cows in my country has been increasing year by year. A large number of dairy farms have entered the ranks of dairy cows with a yield of more than 10 tons per unit, and some excellent dairy farms have exceeded the yield of 12 tons per cow. This has caused a series of problems, such as: dairy cows The service life of dairy cows has been greatly shortened, and the culling rate of dairy cows has been greatly increased. In some high-yielding dairy farms, the annual culling rate of lactating cows has reached 40% or even exceeded. This factor seriously restricts the development of my country's dairy industry. The service life of dairy cows is directly related to the feed nutrition and feeding management durin...

AI Technical Summary

Problems solved by technology

[0007] 1. The so-called uniformity means that a sample is taken at random, and its component content is the same as that of other samples. The uniformity of mixing directly affects the quality of feed products. Due to uneven mixing, the raised animals will ingest The nutritional components of the animal are different. Some components cannot meet the nutritional needs of animals, while some components greatly exceed the animal's ability to bear. The mild ones affect the physiology and growth of animals, and the severe ones cause physiological disorders in animals, leading to poisoning, and even death; on the other hand, the nutritional effect in the feed cannot be fully utilized, indirectly wasting feed resources

[0008] 2. Factors affecting the uniformity of mixing

[0016] (7) Conveyance distance and method: The production of premix is ​​different from that of compound feed. Long-distance conveyance will cause pollution between drugs and grading of finished products, which will affect the uniformity of finished products.

[0023] 5. Stabilization treatment: In the composition of the premix, some mineral salts of trace elements have poor water solubility and are easy to handle in technology, while some are very easy to absorb moisture, regain moisture and agglomerate, which affects processing and feed product quality

Most vitamins are easily affected by factors such as oxygen, humidity, heat, light, and metal ions to reduce their activity.

[0024] 6. Storage time and conditions: Premixes, especially premixes with poor stability such as multivitamins, are often due to the length of storage time and poor conditions such as water content, temperature, humidity, light, and pH during storage. affect its quality and cause the active ingredient to fail

Among the commercially available raw materials, their effective content is also different due to their origin, batch, delivery time, and sales time; therefore, only the raw materials and their proportions are disclosed in the existing patent documents, without considering The proportion of its active ingredients is unscientific, and it is impossible to guarantee the consistency of industrial production
