First, do a good job chicken house renovation and construction. In order to prepare chickens for production, we must first construct a chicken house: The chicken house must be built in a place with high topography, convenient drainage, and good ventilation. It is not advisable to build a field in a low-lying and humid place; The 120-cm skylight window is placed on the side of the room. The drinking fountains and chutes are distributed at the same distance. At the same time, a small door with a height of 160 cm and a width of 70 cm is opened on the side of the sunny side. Sand sports field. The shed should be concrete floor to facilitate cleaning and disinfection. In addition, it is necessary to strengthen the greening to purify the environment of the chicken house. Second, do a good job in production planning. The production plan mainly includes how many chickens are raised each year, how many chickens are raised in each batch, how long the brooding time is, how long the breeding period is, how the chicken house is disinfected, and how the funds are turned around. All of these should establish a timetable, strictly in accordance with the planning of the schedule of the various production processes, as far as possible to rationalize the production, give full play to the maximum production potential, and create the greatest economic benefits. When formulating a production plan, careful consideration must be given to formulating and implementing a plan according to its own specific conditions. The number of chickens raised for each batch of chickens should be compatible with the capacity of brooding, breeding, and adult broilers, and blind brooding should not be allowed. Otherwise, the number of young chicks is increased, and the density of breeding is large. This will inevitably result in insufficient equipment, poor husbandry and management, etc., which will affect the development of the flock, increase the mortality rate and reduce the economic benefits; The waste of homes, equipment, and personnel has increased costs and reduced economic benefits. The number of chicks purchased at a chicken farm has a certain amount of regularity. In a commercial chicken farm, the number of chicks purchased is determined by the number of rearing fat chickens. Based on the number of fattening chickens, plus the number of deaths and eliminations during brooding, it is the number of chicks that need to be purchased. In breeder farms, the number of chicks purchased in general depends on the amount of new hens to be raised in the current year. On this basis, the number of chicks that need to be purchased is further added to the number of brooders, deaths during gestation, and elimination. For example: A field needs 1600 new hens this year, planning to brood until the survival rate of 80% in the rearing period, then 160080100=2000. In the primary hens that are to be purchased, the male-female differential rate is 95%, and 200095100 = 2105, and the initial estimate of the number of newborn mothers to be purchased is 2105. Third, do a good brooding plan. The brooding plan is a specific brooding plan established before the chicks enter the house. The contents mainly include the breed, quantity, feed nutrient level, feed formula, amount of materials used for different age chicks, and how to measure the growth and development of the chicks. Chicks also need to consider how to control the feeding, how to control the light, prevent precocious puberty and so on. In addition, the brooding plan must also devise which brooding methods to use, heat preservation (heatstroke prevention) measures, immunization, and disinfection procedures. The brooding plan is best stipulated by a time schedule to prevent the brooding work from being disordered and causing unnecessary losses. In addition, brooders should set up a variety of records to record various situations during brooding in order to strengthen feeding management. Commonly used records should include dates, chick breeds, chick age, number of inhabitants, deaths, eliminations, room temperature, Consumption and immune conditions. (A) to prepare for brooding. Before the chicks go into the house, they should do a good job of preparations, including the size of the brooding house, the maintenance of the feed, utensils, insulation equipment, debugging and disinfection, and the laying of floor litter. 1. Area of ​​brooding sheds: Feeding a group of broilers should be arranged in advance in order to prevent the lack of broiler houses from affecting the growth and development of chickens. 2. Feed Preparation: Feed for chickens is best prepared in advance according to the number of feeds, variety requirements, etc. before entering the chicks to avoid changes in feed formulation due to lack of feed in the middle, affecting the growth and development of chickens, chickens during the brooding period About 3 kg of chicks are needed. 3. Sterilization of brooding houses and utensils: The brooding house should be well insulated, dry and hygienic, with moderate lightness and ventilation. The ground is sprinkled with quicklime or sprayed with 10% quicklime milk, conditionally available with high pressure water, and blowtorch flame sterilized. The walls, flue, etc. were brushed with 10% quicklime milk, and then 15ml of formalin solution and 7.5g of potassium permanganate were fumigated per cubic meter. The window was airtight for 1-2 days. The playground near the brooding house should be disinfected before use. Umbrella brooders, cages, feed chutes, drinking fountains, etc. are cleaned and disinfected with 1% caustic soda solution and also with 10% caustic lime emulsion, and then carefully rinsed with water and dried in the sun for use. 4. Temperature adjustment of brooding sheds: The brooding sheds and brooders are to be tested for temperature within 2 days prior to the brooding. The temperature in the sheds is preheated to 30-34°C, and the temperature can be checked to adjust them in time. Usually lay a clean bedding on the floor, about 3-5 cm thick. (b) do a good job of ventilation. Do a good job of ventilation and ventilation in the coop, especially in the winter, we must do well in cold insulation, but also pay attention to ventilation. When using coal for brooding, do not close the doors and windows for a long time to prevent poor ventilation. The heating furnace must have an exhaust pipe leading to the outside, and check whether the exhaust pipe is tightly connected and unblocked during use. When fumigation with formaldehyde should be strictly controlled dose and time, timely ventilation after the end of fumigation, reduce the pungent odor and then transferred to the flock. (3) Control chicken density. The stocking density in the house should not be too large. There are 30 1-2 weeks old chickens, 25 3-4 weeks old chickens, 12 chickens 5-8 weeks old, and 8 chickens 9-18 weeks old. After 6 weeks, 6 chickens are suitable. In caged chicken coops, the cages should not be too crowded or excessively standard. (4) If you purchase chicks from other places, pay attention to the following points. One is to contact the chicks in advance for the exact delivery time; the second is to prepare the equipment according to the quantity of the goods, such as rainproof, cold-proof, heatstroke-proof, shading cartons and other tools; the third is to understand the situation of the vaccination of the batch of chicks, disease Chicklings and chicks not vaccinated with Marek's disease cannot be introduced. Fourth, transportation time should be selected. In the winter and in the summer, it should be in the morning and evening. When the transportation time is long, the chicks' dynamics must be checked frequently to observe whether there is heat and cold. Congestion and poor ventilation. After the chicks arrive, let them rest in the transport box and rest quietly for several hours before placing the brooders.
