For broiler breeding, most farmers are now using stacked broiler cages for breeding. The use of broiler cages to raise chickens is more conducive to the management of the chickens by the farmers, and it is also more conducive to the rapid growth of the chickens. However, if the farmers do not use scientific and reasonable breeding methods to raise chickens, it will be difficult for the chickens to grow well. Today, I will give a detailed account of several key breeding points that farmers should pay attention to when using broiler cages to raise chickens.
1. Group the chickens
When the three-dimensional broiler cages are used to raise chickens, most of them use whole sports chicks. When the density of chicks is too high, group them in a timely manner to ensure that the weight of the chicks is even. The first grouping is usually 12-16 days old. The grouping is too early. Due to the small size, It is easy to drill through the gaps in the growing cage, and it will cause a waste of space and energy. The second grouping, at 25-28 days of age, this time grouping should place the heavier healthy parts in the lower layer, leaving the weak young. In summer, because the temperature is too high, grouping can be carried out in advance. In winter, the temperature is cold and the temperature difference between the upper and lower cages is large. You can appropriately postpone the cage time, and put one more in the lower cage to reduce the temperature difference between the upper and lower cages.
2. Control of temperature
three-dimensional cage has three layers. When the temperature outside the chicken house is lower, the temperature difference between each layer is greater. Under normal circumstances, brooding are placed on the highest level, because the highest level has a higher temperature, which is conducive to saving heat. On the first day the chicks enter the farm, the temperature should be controlled at 33-34°C, which can also be adjusted according to the state of the chicks. When the temperature is right, the chickens are evenly distributed, lively, and have a strong appetite. When the temperature becomes low, shrink the neck and bow back and concentrate on the heat source. Squeezing each other, their bodies tremble. When the temperature is too high, water consumption increases, appetite decreases, breathing speeds up, and there is water in neck feathers. In the first week, the temperature drops to 30°C, and thereafter it drops by 2°C every week. The three-dimensional breeding density is high, which is 1 to 2°C lower than the flat rearing temperature. The heat stress of the chickens should avoid the phenomenon of reduced feed intake.
3. Disinfect the chicken house
The chicken house should be thoroughly cleaned and disinfected 5 days before the chicks are put into the house. Here, the farmers need to pay attention to avoid using caustic soda and other corrosive disinfectants for disinfection. After the chicks are in the house, the ground is cleaned every day, and the chickens are disinfected every other day.
4. Drinking water for chickens
After the chicks are placed in the house, make sure that they can drink clean and sanitary water within 2 hours. For the first time the chicks drink water, use warm water at 25°C, add 5% glucose and 0.1% vitamin C to the water, and rinse the waterer frequently. Throughout the brooding period, drinking water should not be interrupted. From the second day of brooding, add anti-pullaria drugs to the drinking water.
Broiler breeding is divided into broiler flat-raising system and broiler cage-raising system. Generally, for farms with less than 30,000 chickens, it is recommended to use broiler flat-raising equipment, which is more cost-effective and requires less start-up capital. For breeding of more than 30,000 chickens, it is recommended to use broiler cage breeding equipment, which has a high degree of automation and saves time and effort, but the price is higher.
