1. Solve thermal insulation and ventilation

The climate in winter and spring is cold, and the temperature required in the house is very different from the outside temperature. It is necessary to ventilate and maintain the temperature in the house. This is the main problem to be solved in winter and spring. The chicken house requires good cold-proof performance to meet the requirements of heat preservation, and strictly prevent the chicks from squeezing to death due to low temperature. If the fermentation bed can increase the temperature in the chicken house, it is recommended to use Yifuyuan fermentation bed strains to make fermentation mattress material for chickens. The fermentation bed can not only keep warm in winter and spring but also achieve zero emissions and no pollution. , No smell.

While ventilating and ventilating, be careful not to cause the temperature in the house to rise and fall, and prevent the disease caused by the stress reaction due to the excessive temperature difference. The vent should be more than 1.5 meters above the back of the chicken. When the temperature drops suddenly and the cold and heat insulation work can not keep up, it is easy to make broilers feel cold outside, and respiratory diseases characterized by coughing, sneezing, tracheal rales, dyspnea and other symptoms occur. Therefore, the breeder should grasp climate change and do a good job in cold and heat preservation. The chicken coop should be repaired to prevent the wind and the wind from invading the flock. Broiler flocks raised on flat ground should be thickened with litter to increase the indoor temperature. Change the litter frequently and open the window at noon for ventilation. In general, ventilate at 6 days of age, and increase the amount of ventilation with increasing age to make the chickens have enough oxygen.

2. Prevent disease transmission

While improving the body's resistance, it is necessary to do a good job in the prevention and treatment of related diseases. Those who are vaccinated against vaccines must be immunized strictly according to immunization procedures. Usually use some drugs to prevent diseases. Sterilize the chicken house regularly. The empty chicken house is best to use formalin fumigation and disinfection. During the breeding period, high-efficiency and non-toxic disinfectant should be used for spray disinfection. Bring chickens to be disinfected regularly, usually by spraying disinfection and drinking water disinfection.

Broilers should seek a veterinary diagnosis in a timely manner after the occurrence of respiratory diseases, and take the appropriate medicine. For symptomatic treatment, some anti-asthmatic and anti-cough medicines can be properly applied to reduce the number of deaths due to breathing difficulties. The principle of prevention and control should adopt comprehensive measures that focus on prevention and supplemented by treatment: establish a strict sanitation and epidemic prevention system, do a good job in environmental sanitation, strictly control the entry of foreigners and vehicles into the production site, and formulate a scientific and effective disinfection system; Monitoring and purification, drug control, immunization, etc. Breeding chickens in winter and spring must solve the contradiction between ventilation and heat preservation, maintain air quality in the house, strengthen hygiene management, and use drugs reasonably so that the incidence rate will be greatly reduced, and the growth and production of broilers can be ensured, so as to obtain ideal economic benefits.

3. Strengthen feeding management

Before entering the chicks, the chicks are strictly washed, disinfected, and fumigated, and the utensils, hats, and houses are thoroughly cleaned. Due to the physiological characteristics of broiler chicks, after entering the house, drink water first and then start to eat. Especially the chickens transported over long distances can timely replenish the water lost by the body. For chickens that are not willing to move, manual bombardment should be adopted to force the feeding, but the movement should be light, so as not to cause death by squeezing. The illumination time should be shortened and not extended. The position, time and intensity of the light source should not be changed at will to make the illumination intensity in the house even.

4. Hygienic management of the chicken farm

First of all, chicks should be introduced from healthy breeding farms to strictly prevent the introduction of pathogens through vertical transmission;

Secondly, a good breeding environment should be created, including a large chicken farm environment and a small environment in the house. The general environment refers to choosing the site as far as possible away from other chicken farms, open terrain, convenient transportation, no noise and other external interference. The indoor environment refers to good thermal insulation and ventilation conditions, equipped with a separate storage room, disinfection tank, dressing room, tool room, etc. Feeding equipment and disinfection equipment are strictly distinguished and disinfected regularly to prevent horizontal transmission of diseases. At the same time, the neighboring chicken farms and local areas are regularly monitored for the occurrence of disease epidemics, and preventive measures are taken. Regularly monitor the health status of the chickens in the farm, and deal with the outbreak in a timely manner;

Third, adhere to the principles of disinfecting chickens, eliminating rodent pests, strictly preventing the spread of disease by rodent pests, burning and burying sick chickens, and separating sick chickens from healthy chickens.
