Problems when paying attention to chickens
1. Don't stop the chickens when they are stressed. If you have just been vaccinated or the chickens that have the disease have to wait until the chickens return to normal, you can only do it because the cuts themselves are a lot of stress to the chickens.
2, 1 to 2 days before weaning, adding multidimensional and glucose in drinking water can resist other stress that appears. Sulfonamides are not used for two days before and after severe abortion. They will prolong bleeding and add vitamin K to water. Add 2 milligrams per kilogram of water. After feeding, add more feed to the feeding trough to reduce the pain of foraging.
3, broken time: broiler: the best weight of the broken crucible is 85 ~ 92g, this time is about 6 to 7 days old, handy, and the chicken body is already strong, the brain is basically not afraid of the thumb fixed when broken Head pressure is best. On the contrary, the body is too large, it is difficult to stop the bleeding, the operation is difficult, the work is slow, and the emergency is large; the body is too small, the health is poor, and it is easy to cause high death.
Grass chickens: The time to switch off is 10 to 15 days old, at which point the switch will not cause a strong stress response. Individuals of grass-birds are small and cannot be prematurely debrided. Usually only one feeding cycle is broken. Because grass-ragged chickens usually adopt open-breeding during the breeding period, they often feed vegetables and grass and need a certain length of earthworms. Therefore, the use of 11 days hot scalding, hot to the tip of the mouth, the same as up and down, not as long as the layer of chicken. The advantage is that the feathers are better and the shape of the mouth is not changed much. If you do not look closely, it will not affect the sale.
4, not at high temperatures and immunization breaks (in the summer you can choose morning and evening), so as not to increase the stress.
5, the need for an experienced keeper to cut off ramming when it breaks, to prevent unevenness. Attention should be focused on when the break is broken, the action is sensitive, the cut length is appropriate, the temperature of the blade of the cutting device must be controlled well, the temperature is too low, and blood will be bleed after the break.
6, the method of breaking
One is the burning method, which is mostly used for broilers.
One is the cutting method using a hot blade to cut the chicken cockroach, this method is mostly used for laying hens. The length of the broken jaw was 1/2 of the upper jaw and 1/3 of the lower jaw (from the nostrils to the ankles). When the knife breaks, the blade burns until it is maroon, hold the chicken by hand, and hold the thumb against the back of the head of the chicken. The index finger presses against the lower jaw of the chicken and gently presses against the throat so that the head of the chicken can't shake right and left. Shrink tongue. Break time is about 1~2 seconds.
