Potassium magnesium sulphate composite crystal slow-release salt product for improving milk yield of dairy cows and preparation method thereof

Abstract

The invention provides potassium magnesium sulphate composite crystal slow-release salt for improving the milk yield of dairy cows, and belongs to the technical field of livestock feed. The potassiummagnesium sulphate composite crystal slow-release salt comprises the following main components in percentage by weight of 50-60% of potassium magnesium sulphate crystal salt, 5-40% of a carrier and 5-40% of plant extract. The specific preparation method comprises the following steps of stirring and mixing the potassium magnesium sulphate crystal salt and the carrier, then adding the carrier, performing stirring and mixing uniformly, adding the plant extract, performing stirring and mixing for 5-10 hours, and finally performing drying to obtain the potassium magnesium sulphate composite crystalslow-release salt product. As a supplement of potassium and magnesium for ruminants, the the potassium magnesium sulphate composite crystal slow-release salt is consistent with body requirements, hasthe characteristics of no heavy metal residues, stable performance, uniform granularity, good fluidity, good palatability and the like, and can significantly improve the milk yield of the dairy cows.

Description

technical field [0001] The invention belongs to the technical field of livestock feed, and in particular relates to a potassium-magnesium sulfate composite crystal slow-release salt product and a preparation method thereof for improving milk production of dairy cows. Background technique [0002] Numerous studies have proven that potassium, magnesium and sulfur are essential nutrients for all animals. In the past, it has been considered that in the diet, the content of these elements in the feed ingredients themselves can meet the needs of animals. Under the conditions of intensive farming today, due to the continuous improvement of animal breeds, the increase of growth rate, the use of low-quality feed materials, and the variation of these elements in feed materials, in order to maximize the production potential of animals and maximize the economy benefit, we have to rethink the potassium, magnesium and sulfur nutrition of animals. Potassium is the most abundant mineral i...

Problems solved by technology

The former dissociates potassium ions quickly, the body absorbs them quickly, excretes them quickly, and has low bioavailability. Potassium in animals is 0.2%, magnesium is 0.05%, and the ratio of potassium to magnesium is 4:1. Potassium magnesium sulfate is commonly used in the market. The ratio is 1.6-2:1, the ratio is unbalanced, inconsistent with the needs of the body
