Sisal hemp residue and king grass mixed silage and preparation method thereof

Abstract

The invention provides a sisal hemp residue and king grass mixed silage which comprises the following components in parts by weight: 35-45 parts of the sisal residues, 55-65 parts of the king grass, 4-6 parts of molasses, 0.5-1.5 parts of urea, 1-5 parts of a traditional Chinese medicine additive and 20-35 parts of grains. The invention further provides a preparation method of the sisal hemp residue and king grass mixed silage. The silage is prepared from the waste residues obtained after processing of the fresh sisal hemp and the fresh king grass so that the silage which is delicious and rich in nutrition is provided for livestock in autumn and winter, and the shelf life of the silage reaches one year or above.

Description

technical field [0001] The invention relates to the field of silage, in particular to a mixed silage of sisal residue and king grass and a preparation method thereof. Background technique [0002] Silage is a kind of feed, which is made of plant feed with high moisture content after sealing and fermenting, and is mainly used to feed ruminants. Silage is more resistant to storage than fresh feed, and its nutritional content is stronger than dry feed. In addition, silage storage occupies less land and there is no fire problem; silage has a sour smell, is soft and juicy, has good palatability, is rich in nutrition, and is good for long-term storage. It is an excellent feed source for livestock. [0003] Kinggrass, Pennisetum genus, is a high-yield, high-quality mowed forage grass, which can be used to feed herbivorous livestock and poultry such as cattle and sheep; Kinggrass has a large growth in spring and summer, high nutritional value, and is suitable for herbivorous livest...

AI Technical Summary

Problems solved by technology

[0003] Kinggrass, Pennisetum genus, is a high-yield, high-quality mowed forage grass, which can be used to feed herbivorous livestock and poultry such as cattle and sheep; Kinggrass has a large growth in spring and summer, high nutritional value, and is suitable for herbivorous livestock and poultry. It is impossible to consume the fresh grass of the season, and the supply of fresh king grass often exceeds the demand. However, in autumn and winter, the growth of king grass is small and the nutritional value is low. Only dried king grass can be fed to cattle, sheep and other herbivorous livestock and poultry. , greatly reducing the nutritional content and palatability of forage

[0004] Sisal, a plant of the Agave family Agaveaceae, is a perennial tropical hard leaf fiber crop; sisal fiber is tough, wear-resistant, salt-alkali-resistant, and corrosion-resistant, and is widely used in transportation, fishery, petroleum, metallurgy and other industries, which have important economic value; the demand for sisal fiber in my country is strong, and the annual self-produced fiber is about 70,000 tons, while the extraction rate of the fiber is only 4.5%, and 95% is waste, so in the process of sisal processing , produce a large amount of sisal slag, if the sisal slag is directly disposed of, it will cause a waste of resources; if the sisal slag and fresh king grass are made into silage for storage, it can be used for feeding herbivorous animals such as cattle and sheep in autumn and winter. Livestock and poultry provide fresh and palatable feed, the purpose of which is to utilize waste resources and adjust the seasonal balance of grass and livestock; for this reason, this application proposes a mixed silage of sisal residue and king grass and its preparation method
