Chicken selection
Some broiler breeders only pay attention to the price of chickens and ignore the quality of chicks. The quality of chickens is the basis for the success of broiler rearing. Only by purchasing healthy chicks with excellent quality, can an ideal feeding effect be achieved. The quality of chicks directly affects the growth of broilers and the economic benefits of the farms. Therefore, it is necessary to select the chicks for the chicken farms with good quality and high reputation, and remove the diseases with omphalitis and white flies when picking chickens. Chickens, eliminate weak chickens and residual chickens, and prevent the purchase of inferior chickens.
Feeding methods
At present, there are many farmers who adopt the ground-level raising method, which can easily cause chickens to catch cold and cause symptoms such as diarrhea, and it is not conducive to the control of intestinal diseases, especially E. coli and coccidiosis are difficult to control. The adoption of “online cultivation†has the advantages of saving litter, reducing coccidiosis, E. coli disease, reducing stress, facilitating environmental control, etc., and making the chicken evenly distributed and conducive to growth. Therefore, broilers are best adopted. Scaffolding and plastic online raising methods.
Heating method
Coal-fired heating is a common heating method for rural chickens. However, when the coal burns, it consumes a large amount of oxygen in the house and generates excessive amounts of harmful gases such as carbon dioxide, carbon monoxide and hydrogen sulfide, which seriously reduce the air quality in the house.
The problem is mainly manifested in several aspects:
1. Poor coal quality, smoke
2. Lead to excessive carbon dioxide in the home
3. Incomplete combustion of coal leads to the production of carbon monoxide
4. The consumption of large amounts of oxygen, resulting in lack of oxygen within the home
It is best to use a fire pit, a heater, or a hot stove for warming.
ventilation
In the early stage, we must not only pay attention to insulation but neglect ventilation. Because of the high temperature, the air is dirty and dry, and the dust flies in the air. It is easy to cause foreign body bronchitis, bronchitis, pneumonia and air-swelling. Ventilation design to leave skylights and about 60 cm above the roof, is conducive to the release of harmful gases such as ammonia, but also to prevent a large number of outside the home from the skylights, "backwards" into the interior, so that the door, window and sunroof form a A good ventilation route helps to discharge the dirty air in the house in a timely manner. Do not neglect the work of heat preservation at the same time of strengthening the ventilation at the later period, especially in the flock of chickens, bad weather, and the temperature difference between day and night, avoid the invasion of thieves and drafts.
Master the humidity
The high temperature in the brooding room often causes the relative humidity in the brooding house to be low, the humidity in the brooding period is too low, the air in the house is dry, the dust is flying upward, the respiratory mucosa is easy to be irritated, the resistance is weakened, and the pathogenic bacteria are inhaled by the chick as the dust flies. Injuries to the respiratory mucosa, resulting in inactivation or detachment of cilia, pathogenic bacteria entering the airway through the respiratory tract, susceptible to respiratory diseases and E. coli disease. The humidity in the house is too small, and it can easily cause a large amount of water loss in the chicken body, dry hair, decreased appetite, increased thirst, resulting in dehydration of the chicks. Therefore, it is also important to keep a good understanding of the humidity inside the house during brooding and keep the relative humidity within the broiler room between 60-70%. Practice has proved that: humidity greater than 80% or less than 40% will have an adverse effect on the growth of chickens. When the humidity is too low, ground watering, air spray, and water basin on the stove can be used to increase the humidity.
Emphasis on selection and breeding
Breeding and group rearing are important factors for ensuring the health and growth of chickens
Picking
The first picking should be carried out when the chicks arrive at the brooding room. The weak chicks and young chicks should be single-fed separately. The remaining chicks should be eliminated to purify the chickens; the second picking should be carried out at 6-8 days of the chicks' age. It can also be carried out when the chicks are first immunized, and small, poorly growing chicks are isolated and fed separately.
Group rearing
The male and female broilers have different male and female genders, and their physiological basis is also different. Therefore, requirements and reactions to environmental and nutritional conditions are also different. If the rooster grows fast, and the hen's growth rate is slow, the difference between the 56-day weight is about 27%; the weight growth rate of the rooster after 8 weeks of age declines, and the weight growth rate of the hen after 7 weeks of age declines, according to economic benefits Should be slaughtered separately. Therefore, it is best to use male and female bred groups to feed broilers. After the male and female broilers are grouped, the ration level can be adjusted separately to better improve feed utilization.
