Fermentation compound feed products and preparation method thereof

Abstract

The invention discloses a fermented compound feed and a production method thereof. In a TMR mixer, premixed fine and coarse feed materials and other nutritional ingredients are pulverized, kneaded and mixed until the particle size, uniformity and water content are desired. Further, microbial fermentation starters are added and water is added during the mixing process to allow the water content of the compound feed to meet the standard. The raw material mixture is compacted and sealed with films by using industrial equipment or directly packed in a sealed container and then subjected to directional and timed fermentation in a predetermined environment, to produce the final fermented compound feed. The product has rich and balanced nutrition, good palatability, high safety, environmental friendliness and convenient transport and use. The invention realizes industrial production and commoditization of feeds for dairy cows as well as resource utilization.

Description

technical field [0001] The present invention relates to a method for preparing fermented compound feed, in particular to a method for preparing fermented compound feed used by dairy cows or other ruminants. It is an industrial fermentation in which compound feed can be added to activated special microbial starter for semi-dry fermentation feed method. Background technique [0002] Feed is the material basis of dairy cow production, accounting for more than 70% of milk production costs. Therefore, modern feed technology is the most basic guarantee for modern dairy industry. Therefore, the United States, the United Kingdom, Australia, Israel and other developed countries in the dairy industry attach great importance to the research of dairy cow nutrition and the development of high-efficiency feed utilization technology. The "Standards for Dairy Cattle Feeding" in the United States is updated every five years, and the seventh edition has been published in 2001. The "Standards...

AI Technical Summary

Problems solved by technology

However, the conventional feed of most dairy cows in my country basically stays on the roughage of corn stalks. Therefore, there are "harmful bacteria, viruses, and residual pesticides exceeding the standard, and the safety performance is poor"; "the quality is not standardized, and the stability is poor"; Common problems such as "poor utilization performance"; "difficult transportation and poor commercial performance"

At present, yellow straw still has individual problems such as "small bulk density, large volume, and difficult to store"; "high degree of lignification, high hardness, peculiar smell, and poor palatability"; "low nutritional value" and other aspects.

Silage has individual problems such as "occupation of land and competition for farming time"; "a large amount of capital deposits"; "high risk in production"; "great waste in opening cellars"

[0007] It is the prevalence of these problems that have seriously affected production: increased disease, excessive antibiotics, and reduced milk quality; insufficient dry matter intake, reduced production performance, and reproductive obstacles; excessive consumption of concentrated feed, causing metabolic diseases, and production Decreased performance; uneven intake of refined and coarse feeds, resulting in nutritional imbalance, reduced production performance and dairy quality; insufficient feed input accuracy, resulting in feed waste or nutritional deficiencies; low labor efficiency, increased management costs, etc.

Thus restricting the efficient development of the dairy industry

[0008] 2. Outdated feed technology and production methods are the root causes of dairy cow feed quality problems

Since farmers are not experts in animal nutrition and are not professional producers of dairy feed, their understanding and mastery of feed technology vary widely, resulting in huge differences in the quality of dairy feed products.

Therefore, it fundamentally hinders technological progress and seriously affects the improvement of product quality.
