First, key first day after we put the broilers into the automatic battery cage system 

We all know that the slaughter weight of a batch of chickens is positively correlated with the weight of this batch of chickens at the age of 7 days. Personally, I think that in addition to the birth weight of chicks, the most important factor determining the weight of chicks at the age of 7 days is the management of the first day. In other words, the first day is very important to the life of chickens

1. Temperature management

After the chicken is put into the house, the temperature should rise in time according to the performance of the chicken, because the first thing is to drink water after the chicken is put into the cage. After drinking water, some chickens often show the phenomenon of getting together. Adjust the temperature in time so that the chicken can slowly adapt

Remember, as long as the chickens get together, it means that our temperature (or the chicken's somatosensory temperature, sometimes our humidity is not added, which causes the somatosensory temperature to fail to rise) is not enough. We should continue to heat (or humidify) until the chicks snuggle loosely (not as loose as the big ones), indicating that the temperature is appropriate

If the temperature on the first day is not reached, and the chicken does not eat, drink or move, it will directly affect the 24-hour satiety rate of the chicken, and then affect the evenness of the chicks and the weight of the 7-day-old chicks

2. Waterline

The waterline is adjusted to 1 or 1 / 2 finger from the bottom of the water cup to the ground. At this height, the angle between the neck and the waterline is about 45 degrees, which can meet the needs of chicks for drinking water

After the chicks start drinking water, use a flashlight to check the water condition of each nipple one by one: as long as there are water drops in the water cup, it means that the nipple water is normal. If the water cup is dry, it means that there is a problem with the nipple

One more thing to say is that we should pay more attention to the water line in cage chicken breeding, because when one nipple is blocked, the chicken can go to the other nipple to drink, and when one water line is blocked, we can go to the other water line to drink. However, as long as the nipples in the cage are blocked, the cage chicken will be short of water

3. Feeding management

You can use a small bucket to assist in feeding, or you can directly use a trough to feed. The small bucket can be used for food. The small bucket can be removed and transferred to the feeding trough after being used for about 3 days. Too long use will increase labor intensity and cause chickens to rely on the bucket

The thickness of the first feeding can be appropriately increased for feeding in the feeding trough to attract the chicken probe to feed and reduce the difficulty of feeding. If the chicken seedling is too weak, it is recommended to use the feeding barrel to assist in feeding

Regularly check whether the reduction of materials in the barrel (chute) is normal. If abnormal blanking is found, it indicates that there are problems in some aspects, such as water line problems, temperature problems, etc. The 24-hour satiety rate should be more than 99%, which means that basically all chickens have drunk water and eaten food

4. The problem of chicken bathing

When some chicks are transported for too long or the temperature is not adjusted properly, they will take a bath. If they are found to have a bath, they should be immediately removed from the nipple to prevent them from continuing to pile up under the nipple. If they have a serious bath, they should be packed in cartons, placed at the radiator to dry their feathers, and then put into the chicken cage

5. The feeding trough shall be used for feeding, and the baffle plate shall be adjusted properly

Generally, the gap of 2cm can be used. If the chick is found running out of the cage, it shall be grabbed back into the cage in time to prevent it from dehydration outside

6. On the first day, work should be well arranged and preparations should be made to stay up late

We should not be too tired to cause water shortage, material shortage or even boiler out and desuperheating. At least one more set of vulnerable hardware such as circulating pump, temperature probe, environmental controller motherboard and so on should be added to a chicken farm in case of need

Second, 2-6 days of management after we put the broilers into the automatic battery cage system 

After drinking the first mouthful of water and eating the first bite of feed, broilers have a conditioned reflex to drinking water and feed. There is no need to worry that they will not drink water and feed. We generally add feed in time in the first 10 days and do not control the feed

Chicks will experience the first ventilation and the decline of indoor humidity in 2-6 days. Personally, I think the first ventilation is still a challenge for chicks, so let's talk about the first ventilation first

First ventilation

1. First ventilation time

In closed chicken houses, the first ventilation time in spring and autumn is generally the third day of age. In winter, the first ventilation time is controlled according to the environment in the house and the external temperature. In summer, especially in the rainy season, it should be adjusted freely according to the indoor air humidity. If the humidity in the house exceeds 75% for a long time, early ventilation should be considered, otherwise the water in the chicken feces will not evaporate in time, causing the chicken feathers to be soaked, Sticking it on the body (as shown in the figure below) also increases the risk of excessive body temperature

2. Ventilation volume

The first ventilation is just a preview of normal ventilation, so that the chicks can get used to the air circulation. We can adopt mechanical ventilation or open small windows for natural ventilation. For example, in the cage of 20,000 chickens, the time for using 1.4 meter blower on the first day can be set at every 300 seconds for 5 seconds or every 300 seconds for 10 seconds for 1-meter blower. Here we need to consider the decline of body temperature. If the humidity in the chicken house decreases by more than 20%, The ventilation volume should be reduced (for example, at 32 ℃, the humidity drops by 20% and the body temperature drops by about 3 ℃

Bucket change

1. For the first time, we can appropriately increase the thickness of the feed and manually draw the feed to the side of the feed trough where there are chickens, so that the chicks can easily feed

2. Once the trough is used, it is necessary to withdraw the finished barrels, otherwise some chickens will not find food in the trough because they rely on the barrels

3. Regularly draw the leftover material surface to the edge of the material trough, so that the chicken can develop the habit of eating material surface since childhood

Waterline

1. On the third day, the height of the waterline can be adjusted according to the height of the chicks. After that, it can be adjusted every two days. The drinking height of the chicks 10 days ago can not be too high. The included angle between the neck and the waterline can be 45 degrees

2. Wash the water line once at 6 days of age. After that, wash it once every time you take medicine. Don't be lazy in management. Blocking the water line can be a headache

3. Weak or disabled chickens should be picked out and eliminated in time. Do not let them infect other healthy chickens in the flock

4. Temperature: it can be reduced by about 0.7 per day and maintained at about 30.5 at the age of 6 days. Don't be reluctant to lower the temperature. Too high temperature will affect the feed intake of chickens, resulting in the weight of chickens at the age of 7 days not reaching the standard

Others: at the age of 3 days, the glandular gastritis was timely prevented by observing the feces. In many areas, the onset of glandular gastritis is earlier than 7 days old, which should not be taken lightly
