Problems solved by technology

It has been reported that 50%-95% of chicken productivity performance depends on environmental conditions, so the modern chicken industry generally uses control of light time and intensity to promote chicken production, but using this method to improve chicken production performance is less than 4%.

Embodiment 1

[0062] In this method, the 1-day-old chicks hatched in different light and color environments were weighed, and the pectoralis major muscle was taken to make paraffin sections, stained with HE, and the muscle fiber area of ​​the pectoralis major was counted. It was found that compared with other treatment groups, green light irradiation during the hatching period could significantly increase chick body weight (3.39%-30.32%), promote muscle growth (4.79%-24.39%) and increase muscle fiber area (15.12%-45.26%). Example 2:

Embodiment 2

[0063] In this method, blood was collected from the heart of 1-day-old chicks incubated in different light and color environments, and the IGF-1 content in plasma was detected. It was found that green light irradiation during the incubation period could significantly increase the plasma IGF-1 content of chicks, which was 22.16% higher than that of other treatment groups. % - 47.17%. Example 3:

Embodiment 3

[0064] In this method, the skeletal muscle satellite cells of 1-day-old chicks incubated in different light and color environments were separated and cultured, and it was found that irradiating the chicken embryos with green light during the hatching period can significantly improve the proliferation activity of skeletal muscle satellite cells of chicks after hatching, and compared with The dark group, white light group, red light group and blue light group increased by 4.76%-37.50%.

Abstract

The invention belongs to the technical field of chick embryo hatchery environment illumination, and particularly relates to a method capable of improving the proliferation activity of skeletal muscle satellite cells in the chick embryo hatching period. The method specifically includes the step that illumination with light in different colors is adopted for hatching in the chick embryo hatching period. The light in different colors includes white light, red light, green light and blue light, preferably, green light. The hatching temperature is kept to be 37+ / -0.5 DEG C, and the humidity is kept to be 50%-60%. As for the light regime, 24 h full illumination is carried out, and the illumination intensity is 15 lx. By improving the proliferation activity of skeletal muscle satellite cells in the chick embryo hatching period, the weight of broiler chickens in hatching and the antioxidant level of skeletal muscles after hatching are effectively increased, and the meat quality is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental lighting in chicken embryo hatching fields, and in particular relates to a method for improving the proliferative activity of skeletal muscle satellite cells in the chicken embryo hatching period. Background technique [0002] Light information is one of the most important factors affecting chicken productivity performance. It has been reported that 50%-95% of chicken productivity performance depends on environmental conditions, so the modern chicken industry generally uses control of light time and intensity to promote chicken production, but using this method to improve chicken production performance is less than 4%. World poultry meat consumption has increased steadily over the past few years, mainly because poultry meat is relatively cheap and readily available. In developed countries in Europe and America, breast meat is the most value-added part of poultry meat, and its output largely...
