1. Grouping
Stereoculture broilers mostly use the whole brood, when the density of chicks is too large to split the flock at the right time, to ensure that the chicks are of uniform weight, the first split is generally 12 to 16 days of age, the split is too early, because the size is too small, easy to burrow in the crevices of the breeding cage, but also cause space waste, thus wasting energy.
The second flock, at 25 to 28 days of age. In summer, due to the high temperature can be appropriately early cage splitting, winter due to the temperature difference between the upper and lower layers of the cage, can be appropriately delayed cage splitting time, and the lower layer of the cage put more than one, in order to reduce the temperature difference between the upper and lower layers.
2.Disinfection
The chicks are thoroughly cleaned and disinfected 5 days before they enter the farm, avoiding the use of corrosive disinfectants such as kerosene to prevent damage to equipment, and the personnel entering and leaving the coop at this time must be strictly disinfected to avoid damaging the disinfection effect, cleaning and disinfecting the troughs and waterers, cleaning and disinfecting the ground every day after the chicks arrive to reduce the stimulation of the respiratory tract by dust and chicken fluff, and disinfecting the whole poultry farm with chickens every other day, alternating with several disinfectant solutions. Disinfection should avoid the vaccination period for more than 24 hours.
3.Temperature
There is a temperature difference between the upper, middle and lower layers of the cage, and the lower the outdoor temperature, the greater the temperature difference. Brooding chicks are generally in the highest layer, because the highest layer has the highest temperature, which is conducive to saving heat energy.
On the first day when the chicks enter the field, the temperature should be controlled at 33-34°C. The temperature can also be adjusted according to the state of the chicks. When the temperature is suitable, the chickens are evenly distributed, lively and active, and have a strong appetite; when the temperature becomes low, they concentrate toward the heat source. Squeeze each other, the body shivers; when the temperature is too high, the water consumption increases, appetite decreases, respiration accelerates, and the neck feathers have water immersion-like.
In the first week, the temperature drops to 30 ~ C, and then drops 2 ℃ per week, stereoculture density, to be lower than the flat temperature 1 ~ 2 ~ C, should avoid causing heat stress and buy food decline.
4. Ventilation
The key to successful breeding is ventilation, reasonable ventilation, can eliminate harmful gases, control temperature, reduce the occurrence of ascites, chronic respiratory disease and E. coli disease and other diseases, three-dimensional breeding unit chicken farm area of high density, so ventilation is more important, chicks into the field within 24 hours due to the overall brooding space, people can not ventilate, with the age of the chickens, gradually increase the amount of ventilation, adjust the location and size of the air inlet As the age of the chickens increases, we can gradually increase the amount of ventilation, adjust the position and size of the air inlet, and adjust the position and size of the air inlet, day and night, cloudy and sunny days, spring and summer, autumn and winter.
5. Use of equipment
Large and medium-sized chicken farms have advanced equipment, but only advanced equipment, not necessarily good chickens, with the increasing degree of scale, automation, breeding failure is not uncommon, the key lies in the organic combination of people and equipment, the operator should not only be familiar with the principle of equipment, but also diligent observation, because the temperature controller and the value of the temperature in the chicken farm has a certain error, to adjust this error value to a minimum, so that Only then can the temperature of the chicken coop be adjusted to the most suitable temperature for chicken growth, in addition, the operator must be skilled in the use of equipment and chicken in each stage of the feeding program, and can timely find and repair equipment failure, once the equipment is used improperly or equipment failure, it will cause huge economic losses.
6. Light
The three-dimensional breeding chicken cage using artificial light, easy to control the light time, the first seven days of brooding, the general use of 24 hours of light, and then gradually drip for 22 hours, the purpose is to let the chicks get used to the dark environment, not due to sudden power outages caused by the flock panic and crush casualties, and then gradually increased to 24 hours of light a week before fencing.
7.Drinking water
After the chicks enter the house to ensure that they can drink water within 2 hours, for some weak chicks, the method of manual dipping can be used to make them drink water, the purpose is to let the chicks learn to drink water as soon as possible.In addition, the height of the automatic water dispenser should be moderate, the drip head is too low, the chicks will stand in the drip head of the water cup and get wet, the drip head is too high, the weak chicks can not drink water; in addition, the pressure reducing valve on the drinking line should be adjusted appropriately, the pressure is too large, the chicks will be afraid to avoid, but also a waste of water resources, the pressure is too small, the end of the chicks drinking water may not reach the standard.As the age of the chickens increases, the water pressure is increased appropriately. The first time the chicks drink water should be 25 ℃ warm boiled water, add 5% glucose and 0.1% vitamin c to the water, the water dispenser should be flushed frequently, throughout the brooding period, the water can not be interrupted, from the second day of brooding, the water is added to the drug to prevent white dysentery in chicks.
