Embodiment 1
[0084] Embodiment one: chicken embryo egg
[0085] As attached to the manual figure 1 As shown, after sterilizing the same batch of 40 breeding eggs according to the conventional technical requirements, pre-incubate them at 28°C for about 4 hours to make the embryo eggs evenly heated, and then adjust to 38°C with a relative humidity of 60% for incubation. Gender determination is carried out at 104 hours. First place the embryonated egg on its side for 5 minutes, and use a LED flashlight to stick to the embryonic egg for inspection. After removing the infertile eggs and dead embryonated eggs, conduct gender determination with the standard position of head up and tail down. , the accuracy rate is 78.26%. Among them, the instruction manual image 3 It is a schematic diagram of the blood line of a male chicken embryo egg, and the manual is attached Figure 4 It is a schematic diagram of the blood line of a female chicken embryo egg, which can be found in the appendix of the man...
Embodiment 2
[0087] Embodiment two: duck embryo eggs
[0088] As attached to the manual figure 1 As shown, after disinfecting the same batch of 40 breeding duck eggs according to the conventional technical requirements, they were pre-incubated at 28°C for about 4 hours so that the embryo eggs were evenly heated, and then adjusted to 38°C with a relative humidity of 60% for incubation. Gender determination is carried out at 120 hours. First, place the embryonated egg on its side for 4 minutes, and use a LED flashlight to stick to the embryonic egg for inspection. After removing the infertile eggs and dead embryonated eggs, conduct gender determination with the standard position of head up and tail down. The accuracy rate is 85.26%. Among them, the instruction manual Figure 5 It is a schematic diagram of the blood line of a male duck embryo egg, and the instructions are attached Image 6 It is a schematic diagram of the blood line of a female duck embryo egg, which can be found in the ap...
Embodiment 3
[0090] Embodiment three: pigeon embryo egg
[0091] As attached to the manual figure 1 As shown, after disinfecting the same batch of 40 breeding pigeon eggs according to the conventional technical requirements, they were pre-incubated at 28°C for about 4 hours to make the embryo eggs evenly heated, and then adjusted to 38.5°C and 60% relative humidity for incubation. Gender determination is carried out at 96 hours of incubation. First, place the embryonic egg on its side for 8 minutes, and use a LED flashlight to stick to the embryonic egg for inspection. After removing the infertile eggs and dead embryonated eggs, conduct gender determination with the standard position of head up and tail down. , with an accuracy rate of 86.5%. Among them, the instruction manual Figure 7 It is a schematic diagram of the blood line of male pigeon embryo eggs, and the instructions are attached Figure 8 It is a schematic diagram of the blood line of the embryonic eggs of female pigeons, wh...
