specific Embodiment approach

[0023] A method for identifying the sex of chicken breeder egg hatching early embryos based on hyperspectral images, the specific implementation is as follows:

[0024] 1. Test material

[0025] The raw material is white-shell chaise hen eggs, which were purchased from a rare poultry breeding farm in Ruian City, Zhejiang Province. The breeding eggs were soaked in 0.1% bromogeramine solution at 35°C for 5 minutes for disinfection, and then put into an incubator at a temperature of 37.8°C and a relative humidity of 65%. Hyperspectral image collection was performed on 94 breeding eggs by number, collected once every 2 days, and detected continuously for 12 days. Among them, 2 / 3 of the samples are about 62 model training sets, and the remaining 1 / 3 samples are about 32 model prediction sets. On the 16th day after the experimental eggs were hatched, the eggs were opened for destructive testing, and the sex of the embryos was manually judged. The accuracy rate of the hyperspectra...

Abstract

The invention relates to a gender determination method for a chicken hatching egg incubation early embryo based on a hyperspectral image, and belongs to the non-destructive testing technology in the poultry propagation industry. The gender determination method comprises the following steps: utilizing a hyperspectral imager to obtain a transmission hyperspectral image on the tenth day of chicken embryo hatching, analyzing difference of spectral response between a male embryo and a female embryo, extracting a spectral value within a wavelength range of 600-900 nm as an input value of a neural network, and judging the gender of the chicken embryo. With adoption of the method, the gender of the chicken embryo can be accurately determined, manual detection after hatching is replaced, the cost in the poultry production industry is lowered, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a hyperspectral image technology method for detecting the sex of hen breeder egg embryos in the early stage of incubation, and belongs to the technical field of non-destructive detection of hatching characteristics in the field of poultry breeding. Background technique [0002] In egg production, the production efficiency of hens is much higher than that of roosters, and in the production of broilers, roosters have higher feed utilization rate, faster growth and stronger vitality than hens. The hatching process of eggs takes about 21 days, which is a time-consuming and energy-consuming process. If we can detect the sex of eggs in the early stage of incubation, better control the ratio of male and female breeding, and meet the market needs in different periods, we can save production costs and improve the production efficiency of enterprises. There is one of the most primitive methods for egg sex identification, which is to ide...
