Embodiment 1

[0021] Cut the fresh king grass short to 2-3 cm, with a moisture content of 75%, directly silage in a plastic bucket, fill and compact the air, and seal it after completion. After 45 days of storage at room temperature, samples were taken. The pH value was 4.66, ammonium nitrogen content 10.45%, lactic acid content 3.50%, and the quality of single king grass silage was poor; neutral detergent fiber content was 66.31%, acid detergent fiber content was 47.89% , RFV is 72.37%, and the nutritional value is low.

Embodiment 2

[0023] Cut the fresh king grass to 2-3 cm short, and then dry it to a semi-dry state with a moisture content of 65%. Use a plastic bucket for silage, fill and compact to exhaust air, and seal it after completion. After 45 days of storage at room temperature, samples were taken. The pH value was 4.34, the ammonium nitrogen content was 9.38%, and the lactic acid content was 4.08%. The quality of single king grass silage was slightly better than that of Example 1. The neutral detergent fiber content was 64.23%, and the acid detergent fiber content It is 45.51%, RFV is 77.41%, and the nutritional value is low.

Embodiment 3

[0025] Cut the fresh king grass short to 2-3 cm, and then dry the king grass to a semi-dry state with a moisture content of 65%, so that the king grass retains good nutrients and material basis as a spare before silage; pineapple peel for mixed silage Prepare 24 hours in advance. Keep the pineapple skins open and stored indoors until the moisture content is 30% as a spare; check for decay and deterioration before mixing the silage; select the above-mentioned raw materials by weight percentage: 90% king grass, 10% pineapple skin mixed Stir uniformly, use silage cellar or plastic bag (barrel) for silage, fill and compact to discharge the air, and seal after completion; after storage and fermentation at room temperature for 45 days, take samples, the pH value is 4.09, ammonium nitrogen content is 7.27%, lactic acid The content of the silage is 5.33%, and the quality of the silage is better than that of Example 2. The neutral detergent fiber content is 59.48%, the acid detergent fib...

Abstract

The invention discloses king grass-pineapple peel mixed silage. The king grass-pineapple peel mixed silage is characterized by being composed of the following raw materials in percentage by weight: 70%-90% of king grass and 10%-30% of pineapple peels. The king grass-pineapple peel mixed silage has the effects that the water content of the king grass is reduced by virtue of air-drying treatment, and the pineapple peels are added to supplement soluble sugar of a silage fermentation substrate so that king grass ensiling succeeds easily; due to the treatment, the pH value and the content of ammonium nitrogen of the silage are reduced, the content of lactic acid in the silage is increased, the quality of ensiling is improved obviously, the content of fibers is reduced and the nutritional value of the king grass silage is increased; an effective king grass ensiling method provided by the invention is simple to operate, and has important significance for solving the problems of unbalanced supply of roughage resources and the like, reasonably utilizing industrial by-products and improving ecological environment.

Description

Technical field [0001] The invention belongs to the technical field of mixed silage and processing and preparation, and specifically relates to a king grass and pineapple peel mixed silage and a preparation method thereof. Background technique [0002] Kinggrass is a high-quality tropical perennial gramineous grass with the characteristics of high yield and good palatability. It is an important source of roughage for ruminant livestock in tropical areas. In winter and spring, Hainan has less rain and lower temperatures, and slow growth of plants, causing a shortage of forage grass. Therefore, in the vigorous growth season of king grass, silage of excess king grass through appropriate methods is of great significance to balance the annual feed supply of livestock and promote animal production performance. [0003] However, king grass has high water content and low soluble sugar content, and conventional method silage has poor quality and low nutritional value. Pineapple peel is a ...
