Laying hen feed and preparation method thereof

Abstract

The invention relates to a laying hen feed and a preparation method thereof. The laying hen feed disclosed by the invention is prepared by using methionine, lysine, multiple vitamins, feed sodium chloride, sodium bicarbonate, monocalcium-dicalcium phosphate, vitamin E, an antioxidant, compound trace elements, phytase, bacillus subtilis, rice husks, choline chloride, calcium formate, calcium lactate and calcium butyrate as raw materials through adopting a multistage mixing method. According to the feed, a proportion and cost of a premix are reduced, and nutritional requirements of laying hens in each of breeding stages can be met, i.e., in the early period of egg laying, common nutritional requirements of egg laying and growth are met, in the middle period of egg laying, the laying hens arewell-proportioned in physique and peak holding time is long, and in the later period of egg laying, the laying hens are good in hair color and good in physique and eggshells are good; health care nutritional raw materials are added, and when nutrients are provided, a health stage of the laying hens in the breeding process is effectively improved, so that the laying hens keep a long peak period, and are good in hair color and strong in physique in the later period of breeding; and the eggshells are high in quality, ruddy and glossy.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a feed for laying hens and a preparation method thereof. Background technique [0002] The laying period of laying hens is divided into the early laying period, the peak laying period, and the middle and late laying period. The nutritional requirements of each stage are different. Most of the feed premixes used in the breeding process during the laying period are products with a ratio of 4-5%. The production cost and transportation cost are relatively high, and the feed space is relatively large. The nutrient concentration of the compound feed produced is low and can be adjusted. The range of nutrient concentration is small, and many laying hens cannot reach the best breeding benefits at the corresponding stage, resulting in many chicken flocks in a sub-healthy state (overnutrition or malnutrition), unable to give full play to production performance, resulting in ...

Problems solved by technology

Most of the feed premixes used in the breeding process during the laying period are products with a ratio of 4-5%. The production cost and transportation cost are relatively high, and the feed space is relatively large. The nutrient concentration of the compound feed produced is low and can be adjusted. The range of nutrient concentration is small, and many laying hens cannot reach the best breeding benefits at the corresponding stage, resulting in many chicken flocks in a sub-healthy state (overnutrition or malnutrition), unable to give full play to production performance, resulting in poor breeding of laying hens. There are many unstable factors, such as: the chickens are weak during the peak egg production period, and the egg production rate drops rapidly; the feather color is poor, thin, sporadic, and the eggshell quality is poor in the late breeding period
