The destruction of the environment has forced a large number of wild animals to go extinct, and the same is true of many wild tortoises. In order to improve the survival rate of turtles, humans have to artificially raise them to increase the production of turtles. If you want to increase the production of turtles, the first thing to do is to increase the fertilization rate and egg laying rate of turtles. So what can we do to make the turtle's spawn rate higher?

1. How to improve the fertilization rate of parent turtles

The main innovation is the method of using artificial rainfall to stimulate the breeding of turtles. Artificial rainfall simulates the natural ecology and can promote the mating of parent turtles. When artificial rainfall is applied, it can be seen that male parent turtles are very excited and chase female parent turtles for mating. The time of artificial rainfall can be selected in the morning, because the temperature difference is relatively small at this time. This method is more effective for box turtles and box turtles; the ratio of male to female is continuously adjusted from 1:2 to 1:3 during the 4-year developmental adaptation period after introduction. Turtles, obey a reasonable ratio and increase the breeding population.

2. How to improve the spawning rate of parent turtles

1. Ecological environment

Environmental requirements It is quiet, the water source meets the national standard, and the transportation is convenient. Turtle ponds are generally east-west, and the area can be large or small, according to local conditions. Build a rest table in the center of the turtle pond to meet the turtle's habit of sunbathing. Set up spawning grounds on one side of the turtle pond or at the junction of the two ponds. Create the best ecology for artificial flushing of yellow-margin box turtles and three-line closed-shell turtles, flushing in summer to ensure a 5cm water level in the tank, in spring and autumn as long as the habitat is flushed before baiting, to lure the turtles out to eat, and satisfy the need to drink water needs. In order to keep the water quality stable, take a small amount of water changes, use beneficial bacteria preparations, such as EM, and sprinkle 10~30ml per cubic meter, which can prolong the aging of the water quality, prevent the water quality from deteriorating, ensure the fertility and tenderness, and continuously improve the ecological environment of the turtle. Further innovation, stacking grass in the spawning ground can effectively promote turtle spawning. The specific method is to pile up straw or grass in the egg-laying ground like a steamed bun, and the turtle will automatically burrow under the grass to lay eggs when it enters the egg-laying ground, which actually creates a quiet environment for the tortoise.

2. Breeding of parent turtles

The key to improving the egg laying rate of parent turtles is to select and breed parent turtles. To select wild species of turtles as parents, it is required that species are pure, large in size, healthy in physique, well-developed, and reach reproductive age. Try to avoid breeding turtles from greenhouses, because although greenhouse turtles can lay eggs, their offspring are lighter in color and are not popular in the market. The reason is that because the parent turtles are selected from the greenhouse turtles and live in the greenhouse without sunlight for a long time, the tortoises whose body color becomes pale, and the offspring reproduced after nurturing the parent turtles have yellow seedlings. If breeding turtles from the offspring generation, it is necessary to shorten the breeding period and shorten the heating time in the juvenile stage. Generally, the heating time is controlled at about 2 months, and it should not exceed one winter age at most. The stocking density is scientific and reasonable. The appropriate stocking density for aquatic turtles is 2.5~3kg/square meter, and for semi-aquatic turtles 4kg/square meter.

3. Feed nutrition

In order to improve the spawning rate of turtles, the feed should be diversified and nutritious. The main feeds used are turtle egg shell powder + quail viscera + tomatoes + cucumbers + earthworms + compound feed + compound vitamins + trace elements. The innovative point is to use turtle egg shell powder and quail viscera. Turtle shell powder can not only increase calcium to meet the needs of turtles to lay eggs, but also use the biological hormones that turtle shell powder may contain to promote turtles to lay more eggs. Quail viscera, intestines, etc. are eaten by tortoises and Brazilian tortoises, while quail eggs and livers are eaten by yellow-margined box turtles and golden turtles with high economic value, especially quail eggs are rich in nutrients and can meet the needs of turtles to lay eggs. Various nutrients and biological hormones. Quail offal is cheap, only 0.7 yuan per 500 grams in the general market, the cost is low, and it can be bought everywhere.

The result of adopting the above method is that the spawning period can be extended by about one month and the spawning quantity can be increased. For every 500 grams of parent tortoises, the total average of males and females, Brazilian tortoises can produce 17 seedlings, 12 tortoises, 4 yellow-throated terrapins, 0.63 yellow-margined box turtles were introduced in the first year, and gradually increased in the second year, reaching a maximum of 1.7. about. No matter what kind of turtle, it generally takes about 4 years from introduction to natural birth. Therefore, breeding turtles is a long-term investment.

Three, how to improve the hatching rate of turtle eggs

The hatching of turtles is an important part of the breeding of turtles. Under normal conditions of fertilized eggs of turtles, the new incubation technology can effectively improve the hatching rate and increase economic benefits. Generally speaking, three elements of temperature, humidity and ventilation should be paid attention to for turtle hatching.
