Improper management will directly affect the physique and egg production of laying hens in the later stage.
To do a good job of feeding and management in the early stage, you must first understand the physiological characteristics of laying hens. We generally divide it into three stages, the brooding stage, the breeding stage, and the egg-laying stage. Do a good job in the early feeding and management, mainly in the brooding and breeding stages.
1. The brooding stage
1-6 weeks old is the brooding period of commercial laying hens. The digestive function of chicks is not perfect after hatching. The need for nutrients depends on two sources. One is to supply nutrient-rich and digestible, high-protein feed; the other is to rely on The nutrients provided by the yolk that are not fully absorbed in the chick's own abdomen. The brooding period is the period of the phylogeny of the chicks. The various tissues and organs of the chicks develop gradually from imperfect or non-functional functions. The chicks have poor resistance to various external stress factors and mainly rely on the protection of maternal antibodies. Diseases are highly susceptible to environmental influences, resulting in pathological phenomena and even death.
2. Breeding stage
7-18 weeks of age is the breeding period. The breeding period is the vigorous period of growth and development. The functions of each system of the body have basically been developed, so the absorbed nutrients are basically transformed into the growth of bones and muscles. With the growth of laying hens, their own The deposition ability of calcium substances will increase, and fat deposition will also increase. If the feed mix is improper, it will easily lead to obesity of the body, which will seriously affect the egg production and egg quality of the laying hens in the later stage. Lay the foundation for the long duration of the peak period and the high egg production rate.
At the same time, it should be noted that the breeding stage is a critical period for the growth of the body. In addition to ensuring the balance of nutrition in all aspects, it is necessary to timely transfer the group, timely change the laying hen feed, increase the light time, and create suitable temperature and humidity for the chickens. and comfortable environment. Go to see the feed crusher machine, which can crush the material.
3. Egg-laying stage
Due to the physiological characteristics of chickens during the laying period, the chickens have strong hormone secretion, strong reproductive system metabolism, light sensitivity, high nutrient metabolism rate, high production intensity and poor resistance. All kinds of stress should be reduced, the occurrence of unexpected events should be avoided as much as possible, and the peak period of egg production should be maintained for a longer time (12 months).
It is recommended to weigh the brooding and rearing stage once a week, and replace the feed of the next stage in time according to the weight standard. When the body weight reaches 1350 grams, it is necessary to increase the light.
