Embodiment 1

[0020] In late November, 350 2-year-old soft-shelled turtles (average weight 435g) were selected as parent soft-shelled turtles for breeding. A total of 264 female soft-shelled turtles and 86 male soft-shelled soft-shelled turtles were selected, with a male-female ratio of 3:1. Keep the light intensity at 4000lux for 7 hours, and control the light at 410lux for 17 hours at other times. After 3 months of cultivation, they will start laying eggs on February 10 and end on September 11. The breeding time will reach 7 months. Statistics on various indicators during the breeding time: 792 nests were laid in total, the number of eggs was 6835, the average number of eggs per nest was 8.63, the average weight of each female turtle was 25.89, the average weight of eggs was 5g, and the average egg fertilization rate was 75.32%.

Embodiment 2

[0022] In late November, 300 2-year-old soft-shelled turtles (average weight 440g) were selected as parent soft-shelled turtles for breeding. A total of 222 female soft-shelled turtles and 78 male soft-shelled soft-shelled turtles were selected, with a male-to-female ratio of 3:1. Keep the light intensity at 3000lux for 7 hours, and control the light at 410lux for 17 hours at other times. After 3 months of cultivation, spawning will begin in February and end in September. The breeding time will reach 7 months. Statistics of various indicators: a total of 798 nests were laid, the number of eggs was 7110, the average number of eggs per nest was 8.91, the average weight of each female turtle was 32.03, the average weight of eggs was 5g, and the average egg fertilization rate was 77.12%.

Embodiment 3

[0024] In late November, 300 2-year-old soft-shelled turtles (average weight 440g) were selected as parent soft-shelled turtles for breeding. A total of 228 female soft-shelled turtles and 72 male soft-shelled soft-shelled turtles were selected. Hours, other time control light 410lux, maintenance time 17 hours, after 3 months of cultivation, began to lay eggs in February, ended in September, the breeding time reached 7 months, the statistics of various indicators during the breeding time: a total of 755 nests were laid, with 5383 eggs, an average of 7.13 eggs per clutch, and an average of 23.61 eggs per female turtle. The average egg weight was 5g, and the average egg fertilization rate was 72.47%.

Abstract

The invention provides a breeding method for improving the reproductive efficiency of turtles, which relates to the technical field of animal breeding. The temperature of breeding is 23-33 DEG C. Theirradiation duration of breeding is 24h per day. The illumination includes first illumination and second illumination which are carried out in turn every day. The intensity of the first illumination is 1000-7000lux, and the duration of the first illumination is 5-10h. The intensity of the second illumination is 300-500lux, and the duration of the second illumination is 14-19h. By using the methodof the invention, the egg laying period can be prolonged to 7 months, the hibernation habit of turtles can be broken, and the average number of eggs laid by each female turtle is 23.69-32.03 in the egg laying period.

Description

technical field [0001] The invention belongs to the technical field of animal breeding, and in particular relates to a breeding method for improving the breeding efficiency of soft-shelled turtles. Background technique [0002] Soft-shelled turtles are commonly known as group fish, soft-shelled turtles, foot fish, yuan fish, clear fish and water fish, etc. They belong to the class Reptiles, turtles, turtles, and soft-shelled turtles. In addition to Xinjiang, Qinghai and Tibet, it is distributed in other provinces, Japan, the Korean Peninsula, the Russian Far East, North America and Africa. The economic value of soft-shelled turtle ranks first among all kinds of freshwater aquatic products at present. The meat is delicious and nutritious, and it is a traditional delicacy in my country. According to analysis, soft-shelled turtles contain essential polypeptides, polysaccharides and amino acids in human life activities, especially proline, hydroxyproline, vitamins A, D, E, DHE...
