JPH08160A - Method for treating domestic fowl - Google Patents

Abstract

PURPOSE:To provide the method for treating the domestic fowl, capable of preventing the drop of the commercial value caused by violently fluttering the wings of the domestic fowl to break the shoulder and the wings and thereby produce a defective product, when the domestic fowl such as a chicken or a duck, especially for a broiler, is treated by cutting its carotid artery with a blade. CONSTITUTION:In the method for treating the domestic fowl by holding the legs of the domestic fowl, nipping its neck with rolls, successively carrying the domestic fowl to a treating table and cutting the carotid artery with a blade on the treating table, an alternating or direct electric current having a voltage of 25-60V, preferably 30-40V, is applied to the domestic fowl, preferably its neck, from 1-2 seconds before the cutting treatment to 3-4 seconds after the cutting treatment. The treating method enables to largely increase the rate of the non-defective products from conventional 60% to 90%, to massively treat the domestic fowl, and to save labors.

Description

Detailed Description of the Invention

[0001]

This invention relates to chickens, especially broilers,
Alternatively, the present invention relates to a method of cutting the carotid artery of poultry such as ducks with a knife and treating it for meat.

[0002]

2. Description of the Related Art Chickens, particularly poultry such as broilers and ducks, have been bred and consumed in large amounts in recent years.
Among them, broilers are bred in large quantities in a form close to factory production, and in order to supply these in large quantities for meat, they are processed by cutting the neck with a knife in a streamlined manner. Then, the leg is grasped, the head is hung down, and the carotid artery is cut by a blade on the processing table while sequentially transferring the rolls to the processing table. At the time of cutting the carotid artery, the broiler makes the wings flutter. By the way, as described above, a broiler is a young chicken that has hatched for 3 months or 100 days, and since such a broiler is bred in large quantities in a form close to factory production, it is very weak and easily damaged. Therefore, as a result of flapping the wings on the shoulders and wings of the broiler, fractures and other defects are generated, and about 40% of the broilers become defects and the commercial value is significantly reduced.

[0003]

The problem to be solved is that when the carotid artery of poultry such as chickens and ducks, especially broilers, is cut with a knife and processed, poultry violently flaps its wings and shoulders. It is the fact that the wings of the wings are broken and the flaws become flaws, resulting in flaws and a decrease in commercial value.

[0004]

The means for solving the above problems of the present invention is, in the invention of claim 1, gripping the legs of poultry and sandwiching the cervical part between the rolls, and sequentially processing them on the processing table. A method for treating poultry in which a carotid artery is cut by a knife on a treatment table while being transferred, wherein the poultry is charged with electricity of 25 to 60 V from 1 to 2 seconds before the cutting to 3 to 4 seconds after the cutting. This is a method for treating poultry.

According to a second aspect of the invention, the method for treating poultry according to the first aspect is characterized in that the voltage applied to the poultry is 30 to 40V.

According to the third aspect of the invention, the method for treating poultry according to the first or second aspect is characterized in that the neck portion of the poultry is used as the electricity-carrying site to be applied to the poultry.

According to the invention of claim 4, the poultry is a chicken, especially a broiler or a duck.
The method for treating poultry according to any one of claims 1 to 3.

[0008]

[Function] By feeding electricity to the poultry 1 to 2 seconds before the carotid artery is cut, the poultry becomes calm and does not flap its wings, and electricity is applied until 3 to 4 seconds after the cutting. By adding it, you will not be able to flap the wings gently even after cutting. The electricity to be charged may be alternating current or direct current. The applied voltage is 25 to 60V. 25V
If it is less than 60V, there is no effect of passing electricity, and if it exceeds 60V, it is dangerous for workers. In particular, if the voltage is too high, there is a risk that the blood vessel may rupture at the neck and blood may be ejected when cut. The applied voltage is preferably 30-40V, especially 35V.
So the poultry is quite quiet and safe for workers. Therefore, put a transformer in the middle of the circuit and
Adjust to V. While sandwiching the neck of poultry with a roll, electricity is appropriately applied to the poultry, preferably the neck of the poultry.

[0009]

[Examples] After hatching, the legs of a broiler kept in a cage for 3 months were grasped and suspended with the head down, and the neck of the broiler was clamped by a roll and transferred to a treatment table. Two seconds before reaching the position of the cutting blade, the neck was clamped by rolls and electricity was started to be applied, and electricity was applied for 3 seconds after the carotid artery was cut. The applied voltage was alternating current, an intermediate transformer was provided midway from the power supply, and the voltage was 35V. When the broiler started to turn on electricity, it became quiet before the carotid artery was cut, did not violently at the time of cutting, and was quiet after cutting. As a result, the treated broilers showed no fractures or other defects.

On the other hand, the broiler treated by the conventional method in which electricity is not applied was violently violent and fractured on the shoulder portion of the wing, so that it could not be used as a product.

[0011]

As described above, according to the method of the present invention, when the carotid artery is cut, a voltage of 25 to 60 V is applied for several seconds before the carotid artery is cut.
By applying the appropriate voltage to the treated poultry, the poultry will not run wild before and after cutting, damaging the wings or breaking the bone, and the proportion of undamaged non-traditional methods will be reduced. While it was 60%, in the case of the method for printing electricity according to the present invention, the proportion of those without damage was 90.
% Or more, and the yield is greatly improved. The method of the present invention can process a large amount of poultry and can save labor.
