The feed intake is an important factor affecting the body weight gain and laying performance of laying hens. The phenomenon of low feed intake of laying hens often occurs in the first line of breeding. The analysis found that in addition to the feed energy concentration and regular feeding and management factors, it also has a great relationship with the development of the gastrointestinal tract of laying hens in the brooding stage. In this paper, two international academic journal articles were selected to extract the main research results, to clarify the effect of corn crushing particle size on the gastrointestinal development of chicks, and to provide reference for the feeding management of laying hens in the brooding stage.

Global warming, the temperature is getting hotter and hotter, we all have a deep understanding. According to the China Climate Bulletin 2023, in 2023, the national average temperature was 10.71 ℃, which was 0.82 ℃ higher than that of the whole year. The temperature in all seasons was higher. The temperature in winter and spring fluctuated greatly. The temperature in summer and autumn was the second highest and the highest in the same period in history. That is to say, the hot temperature is getting higher and higher, and the hot time is getting longer and longer, and the World Meteorological Organization has confirmed that the world will be hotter in 2024!

In 2023, Anchi Animal Nutrition Research Institute and Shandong Laying Hen Technology Innovation Center provided testing services for more than 900 samples submitted by egg and poultry farms in different regions of the country. The test results of corn, soybean meal, bran, stone powder, total material and drinking water samples submitted for inspection in 2023 are summarized and analyzed.

Feeding density is one of the important factors affecting the production performance of laying hens, this paper selects two international academic journal articles, summarizes the translation of the original part of the content, expounds the effect of different feeding density on the production performance and feather coverage of laying hens, and provides technical reference for egg breeding production.

Water is the first nutrient. There are pathogenic bacteria, possible viruses and sediment impurities in drinking water. Compared with hardware improvement, adding acidifier is the most cost-effective way to purify water quality.

Eating 1 mouth and drinking 3 sips of water is the eating habit of pigs and the source of all nutrients for factory-farmed pigs. Therefore, the food safety of pigs is the safety of feed and drinking water.

In recent years, foreign advanced breeding companies have put forward the high-efficiency production target of "laying hens produce 500 eggs in 700 days", which means that the egg production rate of more than 90% is maintained for more than 13 months. The breeding cycle of laying hens in our country is generally about 500 days. When the market is good, the breeding cycle will be extended accordingly. However, the maintenance time of more than 90% egg production rate is generally 8-10 months. Some excellent chicken farms can exceed 10 months, but many chicken farms can reach less than 8 months.

Hailan Company recently released the 2022 Edition of Hailan Brown Commercial Laying Hens Feeding Management Manual. Compared with the 2018 version, the new version has modified some indicators and contents, and also added a lot of management details, which is richer in content and has a very good guiding role in actual production. This paper makes a simple interpretation of the changes before and after some important contents in the 2022 and 2018 editions of the manual.

The brooding period is the key period for the growth and development of laying hens. The growth and development of chicks directly affect the opening weight and evenness of laying hens, and the standard or even exceeding the standard of opening weight and evenness is the most critical factor and irreversible factor for laying hens to exert efficient laying performance throughout the period. Therefore, the industry often says that laying hens are "35 days fixed for life. The brooding period is the key stage of the immune system, digestive system, muscle and bone development of laying hens, and it is also the stage with the highest requirements for nutrition level and quality. According to the special growth and development characteristics of egg chicks at this stage, Anchi Group has designed 810 series of egg chicks with the product design concept of "3366", which can be summed up as "excellent, three strict, six balanced and six additives to protect intestinal tract"

Premix provides basic nutrients such as calcium, phosphorus, salt, amino acids, vitamins and trace elements for laying hens, which is very important to meet the normal growth and development and laying performance of laying hens. Different manufacturers of premixes have their own design concepts and product advantages. The product advantages of Anchi laying hen premixes can be simply summarized as "5233" advantages, which are described in detail below.
