Feed additive manufactured from orange peel and rice bran for beta-xanthophyll-rich and VE-rich eggs

Abstract

A feed additive manufactured from orange peel and rice bran for beta-xanthophyll-rich and VE-rich eggs comprises the following raw materials by weight: 56-58 parts of orange peel powder, 34-36 parts of rice bran powder, 7-9 parts of Lowe's algae powder, and 4-6 parts of an assistant, wherein the assistant is solid beta-cyclodextrin and montmorillonite with the ratio of 7:3. The preparation method comprises the following steps: airing or drying the orange peel, the rice bran, and the Lowe's algae; controlling the water content; grinding to coarse powder of 60-80 mesh respectively; mixing the raw materials according to the ratio and then adding with the assistant; treating with a high energy vibration ball mill for 15-30 min after uniform mixing to obtain the finished product. The feed additive provided by the invention is added into hen overhead price daily ration with the ratio of 1.5-2% continuously for 5 or more days, a hen can lay eggs which are rich in beta-xanthophyll and VE, the beta-xanthophyll content is 4 times higher than that of a control group, and the VE content is 23.4% higher than that of the control group. The feed additive adopts orange peel and other waste to create obvious economical and social benefit.

Description

technical field [0001] The invention relates to a feed additive for producing beta-carotene and vitamin E-enriched eggs by using orange peel and rice bran; it also relates to a preparation method and a use method of the feed additive. Background technique [0002] Vitamin A is one of the indispensable nutrients for the human body.

Problems solved by technology

After the "poisonous capsule" incident in April 2012, consumers had doubts about products such as medicines and health care products that use capsules as packaging materials. Although the hygiene and safety level of capsule production has been continuously improved, consumer confidence has been greatly boosted and has returned to The level before the event was anything but easy

Using orange peel, rice bran and other wastes as feed additives often faces the problem of low animal absorption efficiency, and it is often necessary to increase the amount of addition in order to improve the use effect

This type of plant raw material usually has high cellulose content, and contains astringent and bitter ingredients such as tannin and limonin. Increasing the addition amount will inevitably affect the overall palatability of the feed, resulting in a decrease in feed intake, and the application effect is not ideal
