Method for producing pig feed by fermenting passion fruit peels

Abstract

The invention aims to provide a formula and a preparation method for producing pig feed by fermenting passion fruit peels. The preparation comprises the following specific steps: (1) cleaning the raw material passion fruit peels; pressing for dewatering (the moisture content is about 10%), and crushing; (2) adding 10-20% of corn, 10-15% of soybean meal, 3-5% of sucrose and 5-34% of water into the product obtained in the step (1); mixing for 6-10 minutes to obtain fermentation liquid; (3) adding 3-5% of lactic acid bacteria fermentation liquid into the fermentation liquid obtained in the step (2) to obtain passion fruit peel fermentation liquid, wherein the number of strains in the lactic acid bacteria fermentation liquid is 2*10<6>-2*10<8>cfu / mL; (4) performing anaerobic fermentation of the fermentation liquid obtained in the step (3) at a fermentation temperature of 25-45 DEG C, wherein the fermentation time is 24-48 hours; (5) after the fermentation, performing spray drying of the fermentation liquid in the step (4) to obtain pig feed prepared through fermentation of passion fruit peels. According to the formula and the preparation method provided by the invention, the crude protein content is increased; the palatability is improved; the nutritional value is raised; the viable count of probiotics is increased; the digestion and absorption of nutrient substances by a pig are facilitated; the pig fattening is promoted, and the pork quality is improved; moreover, the fermentation technology has the advantages of simple process, small investment and low operation cost.

Description

technical field [0001] The invention relates to a fermented passion fruit peel pig feed and a production method, belonging to the field of biological feed. Background technique [0002] Passion fruit, also known as egg fruit, is a herbaceous vine of the Passiflora family Passiflora. It is widely planted in tropical and subtropical regions such as Guangxi, Guangdong, Yunnan, and Hainan in southern my country, mainly with yellow and purple fruits. Passion fruit has rich nutritional value and health care value. Passiflora peel is rich in crude fiber and pectin, and fruit pulp is rich in amino acids, mineral elements and vitamins. The juice of passion fruit is often used for processing beverages, candies, etc., and the peel is waste. The passion fruit peel is fermented with probiotics, and the nutrients are used to increase the protein content, reduce the crude cellulose content, save feed resources, reduce feed costs, and at the same time reduce the environmental pollution ca...
