Problems solved by technology

Therefore, the difference between male and female embryonic eggs can be used for gender determination. This method was first reported by Ma Renliu in 1976, but the identification standard he proposed was "the males are more symmetrical on both sides, and the females are not normal on the left and right." It is extremely rough and inconvenient. Operation, repeatability is also poor, since then has not seen practical application

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...

Abstract

The invention discloses a method for lossless determination of genders of poultry embryo eggs. The method comprises the following steps of first, regularly hatching embryo eggs, second, acquiring embryo eggs with proper appearances, third, illuminating and detecting the embryo eggs according to a standard position, and fourth, determining a gender according to an embryo egg vitelline sac bloodline difference determination standard. The embryo egg vitelline sac bloodline difference determination standard is that when vitelline sac bloodline types on the left and right sides of the lower part of the embryo egg are the same, the gender is male; when the vitelline sac bloodline types on the left and right sides of the lower part of the embryo egg are different and the bloodline on the right-lower part is more developed than that of the left-lower part, the gender is female; and when vitelline sac bloodline types on the left and right sides of the lower part of the embryo egg are different and the bloodline on the left-lower part is more developed than that on the right-lower part, the gender is male. With the aid of the determination method for the gender of poultry embryo eggs, lossless determination for gender can be conducted for poultry embryo eggs in early stage; the embryo eggs can be selectively hatched as needed; embryo eggs non-required can be used for other purposes; and production efficiency can be further improved.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for non-destructive gender determination of poultry embryo eggs. Background technique [0002] At present, in poultry production, the sex identification of poultry is carried out at the earliest when the chicks emerge from the shell, mainly through the anal turning method of the chicks or self-sex identification. Since the natural ratio of male and female poultry is roughly 1:1, but there are obvious differences between the sexes in terms of growth and development speed, production performance, economic value, etc., egg production enterprises only need female poultry, while meat poultry production enterprises prefer male poultry. Needed chicks often face the fate of being strangled at birth, raising animal welfare concerns. [0003] Therefore, if the non-destructive sex determination of early embryonic eggs can be carried out with the help of photo-inspection t...
