Preparation method of biological feed of banana stem leaves

Abstract

The invention discloses a preparation method of a biological feed of banana stem leaves, which comprises the following steps of: cutting up the banana stem leaves, then pre-drying till the water content is 70 to 75 percent, adding minor ingredients into the banana stem leaves, then adding cellulase, tannase and third class seed culture solution of lactobacillus plantarum, mixing evenly, extracting air, sealing, storing and preparing to obtain the biological feed of banana stem leaves; and the minor ingredients are pineapple peels, papaya peels or molasses. The preparation method uses the banana stem leaves as major raw materials, generates an acid environment by fermentation of lactobacillus to inhibit spoilage micro-organisms, and can fully develop and utilize by products of fruits, reduce tannin content and coarse fibre content of the by product of banana and improve the palatability, digestibility and nutritional value of the feed.

Description

technical field [0001] The invention relates to a preparation method of feed, in particular to a preparation method of producing banana stem and leaf biological feed by using enzyme preparation and microbial fermentation treatment. Background technique [0002] With the change of food structure and the adjustment of agricultural industrial structure, the production of agricultural feed is paid more and more attention. In the tropics, due to limited land resources and strong competition from high-value crops such as off-season vegetables and tropical fruits, grain production cannot be self-sufficient, and feed grain production is even less. In order to meet the needs of animal husbandry production, a large amount of feed and feed raw materials are often transferred from other places. Due to the influence of high price factors, the development of animal husbandry in hot areas is seriously restricted. How to make full and effective use of local resources to develop feed produc...

Problems solved by technology

However, when producing bananas, a large amount of banana pseudostems, leaves and skins and other residues (about 5 million tons) have also been produced. For a long time, except that a small part is used as fertilizer, most of them are abandoned in the wild and left to rot. waste of resources and pollute the environment

[0004] Fresh banana stems and leaves contain a lot of tannin (tannin), which affects palatability, inhibits the activity of rumen microbial enzymes, affects the absorption of other feeds, and reduces the digestibility of protein; banana stems and leaves have high cellulose and hemicellulose content , and it is difficult to be degraded, so the nutritional value is not greatly improved, and the scope of application is not wide; there are a large number of pathogenic bacteria in the harvested banana stem and leaf residues. If they are not properly treated, these pathogenic bacteria will definitely affect the storage of feed, and even cause Raised animals are infected, and there are 2 anti-nutritional factors in banana by-products: (1) Banana by-products contain a high concentration of tannins (3%), which will reduce feed intake, reduce protein digestibility, and inhibit rumen microbial enzymes (2) bananas are rich in cellulose (43%); greatly restricting the utilization of banana by-products
