AI Technical Summary

Problems solved by technology

However, the soluble carbohydrate content of elephant grass is high, the crude protein content is low, and the nutritional value of its silage feed is low
In addition, the dry matter content of elephant grass is low, and it is difficult to provide sufficient nutritional substrates for lactic acid bacteria during the silage process. Because of the physical characteristics of the empty stem, harmful bacteria will multiply during the silage process, and silage alone is not easy to succeed.

Abstract

The invention provides a processing method of ramie and pennisetum purpureum mixed silage, and belongs to the field of feed additives. The processing method comprises the following specific steps: mixing 60%-80% of pennisetum purpureum and 20%-40% of ramie to obtain silage; then spraying fermentation liquor to the silage, spraying an additive at the same time, and then performing fermentation. Thefermentation liquor comprises compound bacteria, compound enzyme and water, and the compound bacteria comprise lactobacillus plantarum, lactobacillus buchneri, pediococcus pentosaceus and bacillus subtilis; the compound enzyme comprises cellulase, xylanase and laccase; and the additive comprises calcium propionate, molasses, urea, ethanol and water. According to the processing method of the silage, ramie and pennisetum purpureum mixed silage is adopted, nutrients are complemented, the fermentation liquid and the additive are combined for fermentation, the defect that ramie and pennisetum purpureum silage is difficult to silage is overcome, the dry matter and crude protein content and lactic acid bacteria of the silage are increased, and the crude ash content, the acid washing fiber content, the lignin content and the pH value are reduced.

Description

technical field [0001] The invention relates to the technical field of feed additive preparation, in particular to a processing method of ramie and elephant grass mixed silage. Background technique [0002] With the rapid development of animal husbandry in my country, the demand for forage resources has further increased, and the problem of unbalanced supply of high-quality forage has become increasingly prominent. [0003] Ramie is a high-quality unconventional roughage. It is widely planted in southern my country. It has the characteristics of high biological yield, high nutritional value, strong tillering ability, strong regeneration and adaptability. It also has high nutritional value and high crude protein content. A high-quality vegetable protein feed. Silage has a sour smell, soft and juicy, good palatability, rich nutrition, and is good for long-term storage. It is an excellent feed source for herbivorous animals and livestock, and it is also one of the main methods ...
