In the autumn and winter seasons, how should the chicken farms do a good job of heat preservation and feeding, cope with the sudden drop in temperature, reduce the cold stress of the chickens, and reduce the loss?
The key points of chicken breeding at low temperature
1 Appropriately increase the supply of food calories
The proportion of energy components in the feed can be appropriately increased: for example, 10%-20% of corn can be added on the original basis, and at the same time, the amount of feed can be appropriately increased according to the body weight. Every time the temperature drops by 3°C, each chicken day The feeding amount is increased by about 5 grams, and then gradually restored to the original feeding level after the cold current.
2 Keep the chicken house dry
In order to keep warm, the ventilation of the chicken house in winter will be reduced, the moisture content in the air will increase, and the indoor excessive humidity will create conditions for the proliferation of microorganisms. Therefore, you must pay attention to keeping the chicken coop clean and dry. When adding water to the sink, do not overfill it, and do not splash water on the floor of the house.
3 Balance between ventilation and insulation
Due to the low temperature in autumn and winter, it creates excellent conditions for the propagation and spread of influenza viruses. Ventilation is an effective measure to prevent influenza. In order to reduce the accumulation of harmful gases such as ammonia in the chicken house, open windows for ventilation when the weather is clear or when the chickens are moving.
4 Epidemic prevention in autumn and winter
Do a good job in the autumn and winter vaccination of the chicken flock; disinfect the chicken house regularly; add trace elements and antibiotics to the feed to enhance physical fitness.
Chicken house insulation and heating equipment
1 flue heating
Flue heating is the most common heating equipment for chicken coops. It is divided into two types: horizontal flue above ground and underground flue. It is suitable for free-range farmers and small and medium-sized chicken farms, and is suitable for both horizontal and cage breeding.
Above-ground horizontal flue: set up a stove on the outer wall of the chicken house, build 1 or 2 flues in the house according to the size of the chicken house, one end is connected to the stove, and one end leads to the chimney (the chimney should be about one meter higher than the outer wall). The flue heats the chicken house.
Underground flue: The main difference from the above-ground horizontal flue is that the indoor flue is built underground and flush with the ground.
2 Insulation umbrella heating
The thermal insulation umbrella is mainly divided into two parts: the umbrella part and the inner umbrella: the umbrella part is made of galvanized iron or fiberboard to make an umbrella-shaped cover; while the inner umbrella uses thermal insulation materials to facilitate heat preservation.
The heat source of the warm umbrella is generally a resistance wire, an electric heating tube or a coal stove, etc., installed around the inner wall of the umbrella, and an electric heating bulb is installed in the center of the umbrella.
The insulation umbrella with a diameter of 2 meters can hold 300 to 500 chickens. There are several requirements for brooding chicks when using the insulated umbrella: 1. The room temperature is above 24℃; 2. The temperature under the umbrella is 35℃ at a height of 5 cm from the ground; 3. The chicks can go in and out freely under the umbrella.
3 Infrared bulb heating
Using the heat emitted by infrared light bulbs for heating, although the first investment is large, it is simple and easy to use and widely used. In order to reduce heat loss, a heat-insulating lampshade can be added to the infrared bulb. The height of the infrared bulb suspension is 25~30 cm above the ground.
4Far infrared heating heating
The main core component of the far-infrared heating heater is a resistance wire board. One side of the board is coated with a far-infrared coating (black-brown). The resistance wire excites the infrared coating to emit infrared light to generate heat and provide heating.
When installing, place the dark brown coating of the far-infrared heater downwards, 2 meters above the ground. Eight 500-watt far-infrared panels can be used for heating 50 square meters chicken house. In order to maintain uniform heating, a small fan can be installed between the far infrared panels. Although this heating method consumes a lot of power, it has a very good thermal insulation effect.
1 Construction of chicken coop
The effect of heat preservation is related to the size of the chicken coop, so when building a house-in-house, pay attention that the space in the house-in-house should not be too large, the top should be flat, and the sealing should be tight; pay special attention to the low temperature in the back section of the chicken house, which needs to be timely Increase the auxiliary heating equipment such as charcoal boiler; there should be air windows around the chicken house for ventilation.
2 When using flue heating or coal stove heating, pay attention to the tightness of the equipment. If the gas leaks, it is easy to cause gas poisoning.
3 Remove the wet litter in the chicken house in time to reduce the waste gas produced by the fermentation of wet litter.
