Compound premix for laying period of layers

Abstract

The invention discloses compound premix for the laying period of layers. The premix comprises the following raw materials according to parts by mass: 27 to 33 parts of DL-methionine, 11.25 to 13.75 parts of choline chloride, 2 to 2.2 parts of phytic acid enzyme (5000 units / gram), 180 to 220 parts of dicalcium phosphate, 135 to 165 parts of stone powder, 72 to 88 parts of salt, 429.3 to 526.5 parts of fleurage, 25 parts of compound trace element and 10 parts of compound vitamin. Experiments indicate that the compound premix product (green productive material) for the layers has the characteristics of greenness, safety, high laying rate, stable laying performance, strong disease resistance and stress resistance, low feed-egg ratio, good quality of eggs and the like and can be used for producing green egg foods.

Description

technical field [0001] The invention relates to a premix, in particular to a compound premix for laying hens during laying period. Background technique [0002] With the development of my country's laying hen farming industry, the breeding scale has been continuously concentrated, and the breeding efficiency has been greatly improved. In modern intensive laying hen farming, commercial feed (premix, concentrate or compound feed) is widely used to meet the nutritional needs of laying hens and improve the production performance of laying hens. Due to the intensive breeding mode, the breeding density of laying hens is high, and the environmental stress suffered is great. Problems such as unstable egg production performance, high feed-to-egg ratio, and high death rate are prone to occur during production, which seriously affects the development of laying hen farming industry. economic benefits. In order to solve the above problems, anti-stress and health care drugs are often ad...

Problems solved by technology

However, this has led to a series of problems: (1) The residues of drugs and chemical synthetic substances are serious, which directly endanger people's health, and there have been foods that have attracted much attention such as "red eggs" (adding industrial pigment Sudan red to feed) Quality and safety issues; (2) Egg products fail to meet the quality and hygiene standards of exporting countries, and export trade encounters green barriers; (3) Egg quality declines, with low protein concentration, light egg yellowness, poor eggshell quality, and even a large amount of blood. Spotted eggs, etc., reduce the commodity value of eggs; (4) The use of drugs leads to the increase of bacterial resistance, which threatens human health; (5) Fecal pollution is becoming more and more serious, and intensive farming will discharge a large amount of nitrogen into the environment and phosphorus have become increasingly serious pollution sources; due to the unreasonable use of trace elements and drugs in feed, the pollution of land, water and other environments has become more serious
