The Essential Knowledge of Raising Chickens in Autumn

After the laying hens experience high temperature and high humidity in summer, with the reduction of heat stress, their constitution gradually recovers, their egg-laying performance continues to improve, and the peak production season is approaching. Implement different management and prevention plans to create a better production space for chickens to achieve high and stable yields. The following are the strategies I have compiled for you to raise chickens in autumn. I will share them with you, and I hope to provide you with some breeding help!
Always pay attention to the weight of laying hens
Autumn can generally be divided into two stages: early autumn and late autumn. In early autumn, the temperature difference is not large, and the humidity is relatively large. At this stage, laying hens mainly focus on recovering feed intake and physique. Due to the high temperature in summer, the body weight, physique, immunity, antibodies, etc. of the chickens decrease. The feeding management in autumn mainly increases the feed intake and adjusts the nutritional formula appropriately according to the body weight to make up for the weight loss caused by the summer. The production cycle of laying hens is nearly 550 days, and the body weight is always in the rising period, especially the weight of laying hens from 18 weeks to 30 weeks is in the rapid growth period. As a result, the genetic potential of chickens cannot be exerted very well. Here you can use chicken coop mats and imitation eggs to increase egg production. Recommendation: During the laying period, the weight of the chicken group must be checked every two weeks, and the feeding amount should be adjusted according to the target weight of the corresponding breed of laying hens. For flocks with more weight loss, the method of adding light for 1 hour at night can be used to increase feed intake. In autumn, the sunshine time is getting shorter, and whether the feed intake can meet the needs of brooding and rearing chickens, the feeding amount and feed formula can be appropriately adjusted according to the weekly weight gain. In principle, the feed formula is adjusted according to the weight of the chicken. If the body weight is not up to the standard, the original high-nutrition formula will be maintained, and the next corresponding feed formula will be adjusted until the weight reaches the standard.
Always pay attention to gut health
In the early autumn, the humidity is high, and there are many intestinal diseases in chickens. Adding beneficial intestinal flora to the feed can improve the intestinal environment and reduce the damage of the intestinal of the pathogen group, thereby improving the digestion and absorption of the feed, and finally improving the breeding efficiency. Proper ventilation, opening the chicken ventilationwindow, and using the chicken ventilation window when the temperature difference is large can better control the temperature of the chicken house.
Pay attention to the loss of antibodies
The chickens lose nutrients after high-temperature stress, and the Body antibody declines rapidly. In order to make the chickens healthy and stable, it is best to do antibody testing. For suppressive diseases such as Newcastle disease and influenza, the antibody must be detected, and the immunization program and immunization method must be adjusted in time so that the immunity and cellular immunity of the chickens are in a good state. The critical protection value of antibodies against Newcastle disease and influenza H9 is about 9, the range is less than or equal to 3, and the dispersion is about 10%. Do a good job of environmental sanitation before immunization, you can prepare the breeding dosing device, the use of the breeding dosing device can better prevent diseases, and the epidemic prevention effect is best when the chickens are in the healthiest state.
Prevention and control of mosquito-borne diseases
In the early autumn, when mosquitoes and midges breed, and chicken blood parasites and chicken pox are high, attention should be paid to the sewage treatment of chicken farms to remove mosquitoes and midges and reduce their harm. Mosquito fumigation drugs can be ignited in the chicken coop to kill mosquitoes.
Control Lighting
In autumn, the sunshine time is short. For open chicken houses, pay attention to supplementing the light time and light intensity. Light time and intensity stimulate the secretion of estrogen in hens, and temperature-controlled lamps can be used to better observe the egg production of chickens.
Prevent and control the occurrence of respiratory diseases
The late autumn is a period of the high incidence of respiratory diseases. The environment is poor, the temperature difference is large, the management is poor, the disinfection is ineffective, and the mixed infection of various viral and bacterial diseases can easily induce respiratory diseases, which are difficult to cure. It is recommended that you start to improve in the following aspects to reduce the incidence of respiratory diseases.
1. Reduce temperature difference and reduce cold stress. In the initial ventilation, we can use temperature control to change the air quality of the chicken house. If the temperature difference at night is large, we can use the period to control the fan and do a good job of ventilation to reduce the dust and harmful gases in the chicken house.
2. For general viral respiratory diseases combined with antibody detection, adjust the epidemic prevention program and do two immunizations for rhinitis before the start of labor to generate sufficient immunity. It is best to treat frequent rhinitis with antiviral drugs (rhinitis can easily cause sinus inflammation, making chickens susceptible to Newcastle disease virus).
