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 sh

Embodiment 1

[0019] A kind of silage, purchasing the processing residue of bamboo shoots, corn flour, salt and urea as raw materials; wherein the processing residue of bamboo shoots is crushed, squeezed and dehydrated (the moisture content of the processing residue of bamboo shoots after dehydration is 67%), by weight Adding 0.5% of table salt, 3% of cornmeal and 1% of urea, which account for the processing residue of bamboo shoots, stirring and mixing, bundling, covering and fermenting.

Embodiment 2

[0021] Get the silage of embodiment 1 gained in 30 days, 60 days, 90 days, 120 days, 150 days, 200 days, 300 days, 390 days, through sensory evaluation and laboratory analysis, show that the feed of preparation is high-quality silage, details as follows:

[0022] (1), sensory identification method is carried out according to table 1, table 2.

[0028] Score 100~76 75~51 50~26 Below 25

[0029] Samples were taken at 30 days, 60 days, 90 days, 120 days, 150 days, 200 days, 300 days, and 390 days. The measurement showed: pH 3.6-4.1, moisture 65%-66%, maintaining the fragrance of bamboo shoots and bringing comfort The wine smell is yellow, the texture is loose and not sticky, and there is no solid-liquid separation. The comprehensive score is between 83 and 92; the sensory evaluation is excellent.

Embodiment 3

[0035] A total of 12 first-generation (F1) hybrid Simmental x local yellow cattle with similar body weight and body condition were selected and randomly divided into 2 treatments, 6 bulls in each treatment, which were the experimental group and the control group, respectively. The basal rations fed to the test group and the control group were the same, and the silage and rice straw obtained in Example 1 were fed respectively as roughage. The result shows: every beef cattle eats 10~15kg of the silage that embodiment 1 gains every day, increases feed intake, improves daily gain, increases breeding income than the beef cattle fed with rice straw; Specifically as follows:

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 ...
