Silage and preparation method thereof

Abstract

The invention discloses silage. The silage is prepared by using residues of bamboo shoot processing, salt, corn meal and urea as raw materials and carrying out fermentation on the raw materials, wherein, the residues of bamboo shoot processing have a water content of 65-70 wt%, the amount of salt accounts for 0.5 wt% of that of the residues of bamboo shoot processing, the amount of corn meal accounts for 3-4 wt% of that of the residues of bamboo shoot processing, and the amount of urea accounts for 0.5-1.5 wt% of that of the residues of bamboo shoot processing. According to the invention, theshelf life of the silage is prolonged to more than 1 year based on 2-3 months in the prior art, and the nutrient compositions and palatability of the silage are greatly improved. The main physical and chemical indexes and nutrient compositions comprise: a moisture of no larger than 70 %, a pH value of 3.5-4.1, a lactic acid content of no less than 2 % (percentage of dry matter), a butyric acid content of zero, a crude protein (CP) content of no less than 10 % (percentage of dry matter), a crude fiber content (CF) of 22-25 % (percentage of dry matter), a neutral detergent fiber (NDF) content of 53-62 %, and an acidic detergent fiber (ADF) content of 30-42 %.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to silage and a preparation method thereof. Background technique [0002] Bamboo shoots are a traditional delicacy in my country and are known as "mountain delicacy". The output of bamboo shoots in my country ranks first in the world. In 2006, the output of bamboo shoots reached 5 million to 6 million tons. Due to the short time and concentration of bamboo shoots, in addition to fresh sales, about 60% of bamboo shoots are used as processing raw materials to produce canned bamboo shoots and dried bamboo shoots. In the process of processing, the bamboo shoot shells and unfit for consumption are called "bamboo shoot processing residues", which account for more than 50% of bamboo shoots; if calculated according to 50%, there are more than 2.5 million tons of bamboo shoots in the country every year. Bamboo shoot processing residue. Bamboo shoot processing residues have a high ...

AI Technical Summary

Problems solved by technology

Bamboo shoot processing residues have a high moisture content, and at the same time, the bamboo shoot processing season is high in temperature and heavy in rainfall, and is prone to corruption if not handled in time; most processing enterprises discard it as waste and become a source of environmental pollution

[0003] Bamboo shoot processing residues have high fiber content and low lignin, and are good feed sources for ruminants (cattle, sheep, etc.);

There are some test reports on the application of bamboo shoot processing residues to develop feed both at home and abroad. The main problems: the one is to directly utilize the bamboo shoots processing residues for processing. It is inconvenient to store and utilize; the second is that ammoniation and enzymatic hydrolysis are mainly used, and there are problems such as complicated methods and high costs; the third is that the analysis of the material characteristics of bamboo shoot processing residues is not enough, such as the content of fermentable organic matter is low, and the auxiliary materials for its feed development The screening is not perfect, it is difficult to achieve a good feed preparation effect
