In recent years, with the improvement of people's living standards, the development of pollution-free food has become a major direction. There are more and more forests under the forest, but most farmers do not have sufficient skills to control the under-forest cultivation of chickens, resulting in lower economic benefits. Under the forest culture of farm chickens mainly grasp the following links:
1 venue selection
Farming chickens can not be cultivated in any woodland, and should be selected for high dryness, good drainage conditions, good ventilation and light transmission, and it is best to use woodland intercropping for pasture, and avoid under the economic forest (apples, pears, apricots, peaches, etc.) Farm chickens.
2 Grasp the epidemic prevention
Brooding should be focused on brooding in the township (or the head area) in accordance with the growth requirements of the chickens. After about 30 days, they should be stocked in the forest. During the brooding period, prevention work should be done. The specific immunization procedures were as follows: One day of age, subcutaneous injection into the neck with Marek’s disease vaccine. At 5 days of age and 17 days of age, eyes and nose drops were nebulized with neo-kidney 28/86 vaccine. At the age of 11 days and 25 days, the vaccine was administered intranasally to the bursal disease; at the age of 30 days, the new H52 vaccine was injected subcutaneously. After vaccination, those who need to be vaccinated need to be immunized with drinking water and need to be injected or stabbed. They must also arrange chickens to return to their nests at night to segregate the chickens into small groups and immunize them by groups to reduce the stress of chickens.
3 Feed replenishment
According to the situation of forage grass and insect resources in the forest, a reasonable number and number of artificial feedings should be established to ensure that they are provided at least once a day and placed in the evening for supplements. This is more conducive to the normal growth and development of chickens, and improves economic efficiency; drinking water should be kept clean Hygiene, replace drinking water at least once a day, especially in hot summer, but also change drinking water.
4 Environmental disinfection
Because the stocking chickens have direct contact with the external environment, they have put forward higher requirements for environmental sanitation and disinfection work than house feeding chickens. The general site should be disinfected once a week to reduce the presence of pathogenic microorganisms. In the selection of disinfectants, a variety of rotation, cross-use. Commonly used disinfectants include: 1 Compound phenols: bacteria poisoning enemy, farmer's family fungus, fungicide, and children's disease, etc., have a good killing effect on pathogenic microorganisms. 2 aldehydes: glutaraldehyde, ethylene oxide, formaldehyde and other highly effective disinfectants, the gas or liquid have a powerful role in killing microorganisms. 3 quaternary ammonium salts: disinfection -99, 100 poisoning, etc., have good killing effect on bacterial propagules and lipophilic viruses. 4 chlorine preparations: 84 disinfectant, bacteria poison net, excellent chlorine net and so on. Can kill all types of microorganisms, can be used for drinking water disinfection. 5 peroxides: peracetic acid, etc., disinfection effect is good, cheap, but there is a certain degree of corrosion.
