Pig feed capable of effectively utilizing fruit and vegetable wastes and preparation method thereof

Abstract

The invention discloses a pig feed capable of effectively utilizing fruit and vegetable wastes and a preparation method thereof. The pig feed is prepared from the following raw materials in percentageby mass: 60 to 80% of fruit and vegetable waste, 10 to 30% of wheat bran, 5 to 20% of corn flour, and 0.5 to 1% of fermenting bacteria. The preparation method comprises the following steps of pretreating the fruit and vegetable wastes, preparing the fermenting bacteria, mixing, and blending; adding the wheat bran and the corn flour into the blended fruit and vegetable wastes, and uniformly stirring, so as to obtain mixture; boiling, sterilizing and fermenting; adding the fermenting bacteria into the mixture, uniformly stirring, and fermenting for 3 to 5 days, so as to obtain wet feed; performing microwave and low-temperature drying on the wet feed, so as to obtain dry feed; crushing and screening the dry feed, so as to obtain the pig feed. The pig feed has the advantages that the investment is small, the effect is quickly acted, and the market prospect is broad; the preparation cost is reduced, the nutritional value is improved, the palatability is enhanced, the pig is promoted to quickly grow, and the pig feed is a natural health, green and safe organic feed.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a pig feed which effectively utilizes fruit and vegetable waste and a preparation method thereof. Background technique [0002] Fruit and vegetable waste is widely produced in farmers' markets, catering processing stations, transportation transfer stations, and plantations. my country is a large fruit and vegetable planting country, and the output of fruit and vegetable waste is also very large. Randomly stacking and disposing of it is easy to breed bacteria, deteriorate and rot, and produce various pathogenic bacteria, which not only pollutes the environment but also endangers human health. As we all know, fruit and vegetable wastes are rich in organic matter in terms of chemical composition, and are rich in sugar, cellulose, lignin, protein, nitrogen, phosphorus, and potassium. During the stacking process, its properties and odor will have a bad impact on e...

Problems solved by technology

However, in the existing technology, the use of fruit and vegetable waste to prepare feed is generally carried out by mixing the fruit and vegetable waste with cornmeal and then fermenting. The feed prepared by this method has a short storage time and poor palatability. When feeding livestock, it leads to poor appetite and affects the normal growth of animals. At the same time, the production process has not been strictly sterilized, and there are still a large number of harmful bacteria in the feed, which is easy to cause diseases after eating by livestock.
