At present, large-scale breeding of laying hens is booming, but how to achieve more and better economic benefits is a topic of concern to farmers.
The following two aspects of work will achieve considerable benefits.
I. Strengthen environmental management, improve comfort and improve breeding efficiency
1.Ventilation
In the breeding of laying hens, the use of scientific ventilation is a very important and key link. No matter how large the chicken house is, or how large the scale is, the chicken house must maintain good ventilation and fresh air, which is the success or failure of raising chickens. Crucially, this is especially important for high-density chicken farms or small-scale chicken houses. The study found that in large-scale chicken farms if the ventilation facilities are not scientific, this directly affects the air quality inside the entire chicken house. All harmful gases produced in breeding will flood the entire chicken house, such as ammonia, hydrogen sulfide, carbon dioxide, etc.
It will be seriously detrimental to the growth of laying hens, directly affect the egg production rate, and breed many diseases that harm laying hens, resulting in irreparable losses.
Therefore, it is suggested that a large-scale chicken farm should open a floor window at the bottom of the chicken house, a larger window in the middle, and a skylight on the roof, especially in summer, all open for ventilation, but in order to maintain the temperature in winter, only the exhaust pipe and the ground can be used. The windows are ventilated so that the temperature can be kept at a reasonable level.
2.Lighting
In the process of laying hens, scientific regulation of light has a great impact on the improvement of laying hens’ egg production rate. Therefore, extending the time of light is of great significance. It can improve the egg production rate and improve breeding efficiency. Economic benefits, it has been scientifically proved that sufficient light can have an impact on the ovulation of laying hens and thus increase the egg production rate. In fact, light is the best fungicide. It is recommended that the daily light time should be increased by half an hour every week from the age of 20 weeks, but it also depends on the weather. Under normal weather, this standard continues until the laying hens stop laying eggs. If natural light is not enough, artificial lighting must be used to ensure the balance of light in the chicken house. In this way, the characteristics of laying hens can be effectively controlled, better egg-laying conditions can be created, and the peak period of egg-laying can be prolonged…
3.Temperature
In the breeding process of laying hens, the temperature is scientifically controlled. Delayed egg laying period. The temperature is necessary for the normal growth of each animal, but it has different temperature requirements. The reasonable standard temperature of laying hens is 13-23 °C. If the temperature is not in this area, it will affect the laying rate of laying hens. cause an impact. To find ways to make the chicken house meet this standard and raise chickens to achieve higher benefits is to prolong the egg production peak of laying hens. This requires different methods to scientifically control the temperature in different seasons to prolong the egg production peak. In summer, it is necessary to exhaust fans or to use sprinkler water to cool down or reduce the stocking density. Keep the house close to normal temperature.
4.Humidity
In the breeding process of laying hens, scientifically maintaining environmental humidity is also a key factor affecting laying hens. The reasonable humidity of laying hens is 60-70%. If the humidity is too low, the feathers of laying hens will be disheveled. Dry skin can cause respiratory diseases and severe breathing disorders
hindrance, resulting in death. The humidity is too high, which will accelerate the reproduction rate of some bacteria, and also cause diseases, which will reduce the egg production rate.
During the breeding process, keep the humidity in the house standardized at any time to prolong the laying period.
5.Environmental hygiene
In the process of laying hens, it is necessary to do a good job of environmental sanitation. If sanitation is extremely poor, bacteria will breed. The laying hens have a poor physique and low immunity during the laying stage and will infect some diseases that affect egg production. The manure is treated harmlessly to ensure the health of the chickens.
II. Strengthen feeding management, improve chicken quality and improve breeding efficiency
- During the breeding process of laying hens, always pay attention to check the overall level of the flock and pay attention to the egg production rate. Egg production rate is a key factor affecting the efficiency of breeding. During the egg production process, some chickens cannot achieve the best health status for some reason, which directly affects the economic benefits of chicken farms.If the chickens are in good condition, you should find out the reasons in time, carry out the re-selection of some chickens, and focus on screening the whole flock. First, look for disheveled feathers, dry and shrunken combs, dark yellow heads, beaks, and shins, and secondly, look at abdominal muscle hypertrophy. , and eliminate some of the poor health, to see if they are infected with some Infectious diseases, timely treatment. Under normal circumstances, if the egg production rate drops to about 50%, the chicken selection work should be started. After the selection, observe the egg production rate of the flock. In this way, the flock can always maintain high yield efficiency.
- During the normal egg production process of chickens, farmers should collect eggs in time. The time to collect eggs should be fixed and punctual, generally within 4 hours after sunrise, because chickens lay more eggs at this time, the number of eggs collected every day is subject to 2-3 times, and there is a fixed time for stuffing and cleaning manure, This will not affect the normal production and rest of the laying hens, create a good and quiet environment for the laying hens, and minimize the noise around the hen house as much as possible. Break into the chicken coop and kill rodents in time.
- In the production process of laying hens, sufficient water and good feed are the keys to improving the egg production rate. Under normal circumstances, a laying hen drinks 250-400ml of water per day. If the laying hen does not drink enough water, the egg production rate will drop by 2%-5%. Pay attention to water quality while supplementing water. Water can cause a stress response to laying hens and reduce egg production. High-quality, full-price feed is the key to meeting laying hens’ production, increasing egg production rate, and delaying peak egg production.
There are many problems in improving the breeding efficiency of laying hens, but by grasping the above aspects, the breeding efficiency of laying hens will be multiplied by half the effort.
