Abstract

The invention relates to a compound feed additive and a feed for laying hens in growing period. A preparation method of the compound feed additive comprises the following steps: mixing shrimp shell powder, bran and glucose, adjusting the water content, and sterilizing to obtain a mixture; inoculating phellinus igniarius hyphae into the mixture, and performing solid-state fermentation to obtain a fermented material; and drying and crushing the fermented material to obtain the feed. The invention also discloses the feed containing the compound feed additive for laying hens in a growing period. The compound feed additive disclosed by the invention is added into the feed for laying hens in a growing period, so that the yield and the quality of eggs can be remarkably improved, and the requirements of the market on high-quality eggs can be well met.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a compound feed additive and feed for laying hens in the growing period. Background technique [0002] Eggs contain high content of protein, lecithin and other ingredients, as well as vitamin A, vitamin D, iron, phosphorus, calcium and other micronutrients, which can provide essential nutrients for the human body and are a daily food with a large consumption. With the improvement of people's living standards, the demand for high-quality eggs continues to increase. How to improve the quality and output of eggs has become the focus of many researchers. [0003] The production efficiency of eggs is closely related to the feeding level of laying hens, especially in the breeding period of laying hens, by rationally adjusting the composition of feed, the quality and yield of eggs can be effectively improved. Shrimp shell powder is processed from shrimp shells. It is rich in active ingred...
