Beak cutting method
When cutting the beak, the surgeon holds the chicken in his left hand, with his thumb against the back of the chicken’s head, and the index finger on the lower part of the chicken’s neck. Lightly press the chicken’s throat to shrink the tongue so as not to cut the tongue. Pay attention not to use too much force, it is advisable to not shake the chicken head from side to side. Middle finger breast protector, hold the chicken body in the palm of the hand, clamp the two claws between the ring finger and the little finger to fix it, and then tilt the chicken head toward the blade to make the upper beak cut more than the lower beak.
The part of the beak cut
The upper beak is from the end of the beak to 1/2 of the nostril, and the lower beak is from the tip of the beak to the 1/3 of the nostril. Note that the growth point is cut off, and the remaining part is separated from the nostril by 2mm. The cross section of the cut part is brown and there should be no bleeding.
Precautions when cutting the beak
Do not cut the beak when the flock is under stress. For example, in a flock that has just been vaccinated or has a disease, you must wait until the flock is back to normal. Do not cut your beak when using sulfa drugs, otherwise it will easily cause bleeding.
It is best to use a fully automatic beak cutting machine. The blade should be sharp, and the joint between the blade and the orifice plate should be tight, the blade is dark red, and the temperature is between 650~700℃. When the temperature is too low, the beak is easy to be torn off instead of being cut, and it is easy to bleed; when the temperature is too high, the beak is easy to stick to the blade, and the beak is damaged.
It is forbidden to enter the broken beak hole when the upper and lower beaks are opened, otherwise the chicken tongue may be cut off or burned.
The length of the broken beak must be appropriate. Insufficient beak cutting is prone to form pecking habit in the later stage of laying, and the effect of beak cutting is not achieved. Excessive beak cutting will affect the drinking and feeding of the chicks, which in turn affects the development of the chicks.
Since chickens often have severe stress reactions after beaking, it is necessary to strengthen the feeding and management of chicks after beaking. Within one week after the beak is cut off, adequate feed should be given to reduce the pain caused by the wound touching the trough and affect the feeding; the drinking water should be kept fresh. Do not perform epidemic prevention or other operations within 1 week after the beak is cut to avoid aggravating stress. Vitamin A, vitamin C, vitamin K and electrolytic multi-dimensional etc. can be added to the feed to reduce bleeding and stress after beak cutting in chicks.
Beak cutting may induce chronic respiratory diseases, staphylococcal diseases and other diseases. Therefore, it is necessary to strengthen the sanitation and disinfection work such as cages before and after cutting the beak, and put antibiotics in time to prevent it.
If the beak is not completely cut off, the beak can be cut a second time during the breeding period (10 to 14 weeks of age). 24 to 48 hours before the second beak cutting, vitamin K should be added to the feed to prevent bleeding.
