Laying hen fodder additive produced through orange peel, bean dregs and other waste

Abstract

A laying hen fodder additive produced through orange peel, bean dregs and other waste is prepared from, by weight, 12-14 parts of orange peel powder, 11-13 parts of bean dreg powder, 34-36 parts of litchi seed powder, 4-6 parts of mulberry twig powder, 3.9 parts of ochromonas and 8 parts of auxiliaries. The auxiliaries are prepared from carboxymethyl cellulose sodium, L-arginine and hydroxypropyl chitosan according to the ratio of 1.2 to 1.7 to 2.1. A production method includes the steps of mixing coarse powder of all the raw materials according to the ratio, mixing the raw materials with the auxiliaries, processing the mixture through a high-energy vibration mill for 15-30 min, conducting shutdown for 2.5 min, conducting processing for 12-13 min, making all the raw materials subjected to two times of different solid mechano-chemistry reactions, and conducting screening through a 400-mesh sieve to obtain the finished product. When the product is added to laying hen fodder and fed to laying hens for 3 or more days, the yolk color of eggs can be remarkably improved. The color value of yolk is improved by one or more times compared with the color value of the contrast group and the color value of the overhead-price ration group, the application effect is obvious, considerable economic benefits are brought to the laying hen breeding industry, and meanwhile waste is turned into wealth and environment protection is facilitated.

Description

technical field [0001] The invention relates to a feed additive for laying hens produced from orange peel and bean dregs, and also relates to a method for producing the feed additive. Background technique [0002] Egg yolk color is one of the most important items in egg production indicators. The depth of egg yolk color is directly related to the sales method and sales volume of commercial eggs. For example, processed eggs with high added value, such as salted eggs and preserved eggs, require darker egg yolks, while fresh eggs with egg yolks less than grade eight cannot be exported to earn foreign exchange. Even in the domestic market, they can only be sold at a lower price. Meager, difficult to enter the high-end market. The pursuit of darker egg yolk color is not an irrational consumption habit of consumers. The darker egg yolk color indicates that some of the nutrients are indeed richer (except those made by chemical synthetic dyes such as Sudan red and Jialisu red). ...

Problems solved by technology

But the core problem to be solved is that the active ingredient in the peel has a low animal absorption rate, the peel is poor in palatability, and the humidity is high and it is easy to rot, etc.
