Embodiment 1

[0011] Embodiment 1: The influence of electric anesthesia voltage on chicken's red head phenomenon

[0012] Take 9000 chickens in the same feeding state and divide them into 9 groups, 1000 chickens in each group. The electric anesthesia voltage is 0V, 15V, 30V, 35V, 40V, 45V, 50V, 60V, 70V, and the voltage time is controlled at 3-5s. , Complete the assassination and bloodletting process within 30s after the corona. After slaughtering, compare the red head phenomenon of chickens.

[0013] The following table shows the effect of electric anesthesia voltage on the red head phenomenon of chickens:

[0014] serial number

[0015] It can be seen from the above table that when the electric anesthesia voltage is 35-45V, the bloodletting effect of the chicken is better, and the chicken basically has no red head phenomenon. Considering the cause of the red head phenomenon, choose 40V as the best electric anesthesia voltage

Embodiment 2

[0016] Embodiment two: the impact of electric anesthesia time on the red head phenomenon of chicken

[0017] Take 7000 chickens in the same feeding state and divide them into 7 groups, 1000 chickens in each group. The electric anesthesia voltage is fixed at 40V, and the electric anesthesia time is 1s, 2s, 3s, 4s, 5s, 6s, 7s respectively. Complete the assassination and bloodletting process. After slaughtering, compare the red head phenomenon of chickens.

[0018] The following table shows the effect of electric anesthesia time on the red head phenomenon of chickens:

[0019]

[0020] It can be seen from the above table that when the electric anesthesia time is 4s, the bloodletting effect of the chicken is better, and the chicken basically has no red head phenomenon.

Embodiment 3

[0021] Embodiment 3: The impact of electric anesthesia assassination interval time on the red head phenomenon of chicken

[0022] The interval between electric anesthesia assassinations is too short, which has a great impact on the difficulty of operation and personal safety. Chickens will wake up about 1 minute after being stunned. If the interval between electric anesthesia stabbing is too long, the chickens will gradually wake up, and the stress response will gradually strengthen, resulting in the red head phenomenon.

[0023] The assassination and bloodletting process is completed within 25-30s after the corona, which can reduce the stress response of the chicken, improve the bloodletting effect, and basically cause the red head phenomenon.

Abstract

The invention discloses a method capable of reducing red head phenomenon of chicken. According to the invention, in a chicken slaughtering process, the voltage of an electro-anesthesia process is controlled to be 35-45 V and the time of the electro-anesthesia process is controlled to be 3-5 seconds; and after the electro-anesthesia, killing and bleeding processes are completed within 25-30 seconds. By the method, the normal heart beating of chicken can be ensured after electro-anesthesia, chicken can naturally recover consciousness within about 1 minute, the bleeding amount of the chicken is guaranteed, the red head phenomenon of chicken is reduced, the quality of chicken product is improved, the safety of operators is also ensured, animal welfare law is implemented, and the economic benefits of live chicken slaughtering enterprises are greatly improved.

Description

Technical field: [0001] The invention relates to a production method for slaughtering raw chickens, in particular to a method for reducing the red head phenomenon of chickens. Background technique: [0002] In recent years, with the adjustment of my country's meat consumption level, chicken products are deeply loved by consumers. The raw chicken slaughter industry continues to grow and grow, and the annual slaughter of chickens is also increasing. Electric anesthesia and bloodletting are the key processes in the slaughtering process of raw chickens, which are not only the external manifestations of the implementation of the Animal Welfare Law, but also have a great impact on the quality of chicken products, mainly reflected in the phenomenon that chickens are prone to red heads. [0003] The red head phenomenon refers to the phenomenon that the head of the chicken is congested and the head of the chicken is red due to the continuous bleeding during the slaughter process. Th...
