Problems solved by technology

This by-product has high sugar and moisture content, and the fresh material is prone to mildew and is not easy to store, so most of it is treated as waste, polluting the environment, acidifying the soil, and a small amount of fresh navel orange pomace is used as feed for pigs, cattle, and sheep
[0003] Because navel orange pomace contains navel orange peel, it has low protein content, high fiber content, high sugar and water content, low amino acid content, bitter taste, poor palatability and low digestibility
Lysine is an essential amino acid and a limiting amino acid for the growth and development of animals. The lack of lysine will seriously affect the absorption of other amino acids, resulting in serious hindrance in the growth and development of animals and the performance of production performance.

Abstract

The invention relates to the field of fermentation feed, in particular to a method for preparing a high-content lysine feed through fermentation of navel orange pomace. The method includes the following steps of firstly, using the navel orange pomace as the basic fermentation substrate, and adding some nutrients for bacteria growth and reproduction and a lysine production bacteria solution; secondly, weighing the navel orange pomace to be smashed, adding wheat bran and urea to be evenly mixed, sequentially adding the lysine production bacteria solution, a KH2PO4 solution and a MgSO4 solution to be evenly mixed, and conducting drying and smashing after fermenting. By using the navel orange pomace as the fermentation substrate, one or more bacteria for lysine production are inoculated, the high-content lysine fermentation feed can be produced after fermentation under the certain temperature, water content, inoculation amount, time and other conditions, the nutrients of the navel orange pomace are improved and added to the feed to replace part of or the whole of lysine, the feed cost is reduced, the feed conforms to the environmental protection requirement, waste is turned into wealth, the environmental pollution is reduced, and the additional value of byproducts obtained after navel oranges are processed is increased.

Description

technical field [0001] The invention relates to the field of fermented feed, in particular to a method for preparing feed with high content of lysine by fermenting navel orange residue. Background technique [0002] Navel orange pomace is a kind of by-product obtained by processing and pulverizing the remaining pulp, pulp, core, fruit capsule, pericarp and discarded secondary fruit after the navel orange is squeezed. This by-product has high sugar and moisture content, and the fresh material is prone to mildew and is not easy to store, so most of it is treated as waste, polluting the environment and acidifying the soil, and a small amount of fresh navel orange pomace is used as feed for pigs, cattle, and sheep. [0003] Because navel orange pomace contains navel orange peel, it has low protein content, high fiber content, high sugar and water content, low amino acid content, bitter taste, poor palatability, and low digestibility. Lysine is an essential amino acid and a limi...
