What kind of conditions are needed for frog breeding
Aquaculture pond: the aquaculture pond should be built in a humid, warm and dark place, the surface of the pond must be equipped with shading board, and a small amount of floating aquatic plants should be put into the water. Feed management: different breeding methods are adopted in different stages, and feed should be put in time, quantity and location. Frog reproduction: artificial reproduction is dominant, and female and male frogs should be released according to the ratio of 3:1.
I. Construction of aquaculture ponds
1. Frog culture ponds are divided into spawning ponds, tadpole ponds and adult frog ponds. Generally, it is suitable to build in a place that is both wet and warm from the sun, and the long cement pool or soil pool is the most suitable.
2. The field large pool is 4 × 6 meters as a single pool, the wall of the pool is better smeared with cement, the bottom of the pool is still muddy, and the courtyard pool is generally 1 × 1.5 meters to 2 meters.
3. The depth of the pond is generally about 1 meter, and there are irrigation holes and drainage channels in the pond, with a water depth of about 20-50 cm.
4. The surface of the pool must be equipped with a shading board. Generally, 40 adult frogs can be raised per square meter. Frog culture ponds can be used in soil ponds, brick ponds and rice fields, and the key is to prevent frogs from escaping.
5. If you have the conditions, you can build a brick wall or a net, which is generally 1-1.2 meters high. The water depth in the pond is 30-60 cm, and the central or sunny side of the water is piled into a mound for frogs to live on land, accounting for about 1 of the total pollution.
6. Plant grass or crops on the mound. A small amount of floating aquatic plants should be put into the pool water.
7. The pond used to cultivate tadpoles leaves only a small amount of land area for abnormal young frogs to land.
8. The cement pond is better for the tadpole pond, and the slope of the pool wall should be gentle for the tadpole to inhabit.
II. Feed management
The main results are as follows: 1. Frog culture methods will be different in different stages, and only by adopting different culture methods in different stages can the survival rate of frogs be guaranteed.
2, and the feed should be put in time, quantity and location. It is generally released around noon in spring and autumn and in the evening or morning in summer.
3. Frog feed should be fresh, clean and nutritious.
III. Breeding techniques of frogs
The main results are as follows: 1. the key to the feeding technology of frogs is artificial reproduction, because wild field frogs often have a parasite with double-groove cercariae parasitic in their muscles, and the method of artificial spawning and isolation of adult frogs can effectively prevent the disease.
2. Frogs should be planted according to the density of about one group of frogs every 3 square meters, and the investment should be started before May.
3. The breeding frog requires individual hypertrophy, and the parent frog that has been laid for 1 year or 2 years is better, the mixed stocking ratio of male and female is 3:1, and the stocking density is relatively less than that of meat frog.
4. it takes about three years from young frog to sexual maturity. the management of breeding frog should strengthen the feeding of protein feed, mainly earthworms and moths.
5. In order to maintain the normal balance value of the pool water, it is necessary to be fat and alive, and prepare for spawning and hatching when the water temperature is stable at about 22 ℃.
6, more than 50 grams of female frogs can lay a lot of eggs at a time, generally male and female embrace to lay eggs on aquatic plants.
7. The frog eggs are yellowish and round, and float on the aquatic plants in pieces attached to the glial egg membrane, which can be easily identified.

Feeding and management of pregnant cows
Early pregnancy: because the growth of the embryo is relatively slow, it is not suitable to be overfed, but only needs to be raised according to the standard of empty period. The second and third trimester of pregnancy: due to the accelerated growth and development of the embryo, especially in the last 2-3 months, it is necessary to increase the amount of feeding.
