Detailed Explanation of Key Technical Points for Laying Hen Feeding and Management
Laying hens are mainly raised for egg production, so we need to choose laying hen breeds with a high laying rate, large eggs, fast growth, and early maturity. There are certain differences between raising laying hens and raising broiler chickens in terms of management, so how should laying hens be raised and managed? Below, let us look at an introduction to laying hen feeding and management techniques.
1. Management during the brooding period
The purchased chicks need to be disinfected before being placed into the breeding farm, and the breeding farm needs to undergo comprehensive disinfection management before breeding. Next is to do a good job of sanitation in the breeding farm and keep the breeding environment clean and tidy. We must provide sufficient drinking water every day, and at this time the drinking water should mainly be brown sugar water or glucose water. Carry out preliminary grouping according to the strength of the chicks, so that feeding can be carried out scientifically and the brooding survival rate can be improved. Also, for laying hens during the brooding stage, their requirements for temperature, humidity, and light are relatively strict. During this period, the temperature inside the breeding room is best controlled between 30 and 35 degrees, and then the temperature is reduced by 2 degrees every week. The humidity of the breeding farm should be controlled at around 70 percent in the early brooding period, and later reduced to between 55 and 65 percent. Finally, according to the age in days of the chicks, reasonably control the duration of light. From 1 to 3 days of age, the light duration is 23 hours; from 4 days to half a month, the duration is 18, and afterward it slowly returns to normal.
2. Management during the growing period
Sanitation management during the growing period should be carried out normally, and this is a daily management task that must be done in every growth stage. The period from when the chicks grow to 7 weeks old to 20 weeks old is the growing period. First, we need to do a good job of flock transfer, selecting sick, weak, and disabled chickens, and then carry out the transfer. At the same time, during the transfer process, stress reactions should be avoided. Second, we need to control the body weight of the laying hens, limit their feed intake, and reduce fat accumulation, so as to improve the quality of the laying hens. Also, attention should be paid to density management and light control in breeding. The light duration for laying hens should not exceed 16 hours at most. Finally, we must strictly follow the immunization procedure to prevent the occurrence of fowl plague or other diseases and pests.
3. Management during the laying period
In the laying period of laying hens, the first thing to do is to grasp the timing of feed replacement, replace the feed in a timely manner, and supplement nutrition. Second, reasonably control the light duration and light intensity, generally 16 hours, with intensity twice as strong as during the growing period, so as to stimulate production. Finally, its management during the laying period is generally divided into three stages, namely the early laying period, the peak period, and the late laying period. In the early laying period, attention should be paid to feed replacement and timely water supplementation to avoid stress reactions, and at the same time a dose of medication to prevent salpingitis should be used once. During the peak laying period of laying hens, what we need to do is extend the laying period and increase the laying rate. At this time, feed supply must be stable, and situations such as feed outage, water outage, and power outage must not occur, and the breeding conditions in all aspects should also be balanced. The late laying period is also called the final laying period. We need to replace the feed again, lower the feed grade, pay attention to calcium supplementation, and do a good job of epidemic prevention.
