CATDOLL : CATDOLL: What are the methods of artificial insemination of fish and how do they work?

1. What are the methods of artificial insemination of fish and how to perform it?

There are three methods of artificial insemination of fish: dry method, semi-dry method and wet method. For dry artificial insemination, first use a fish stretcher to place the female and male fish separately, drain the water, and wipe the remaining water on the fish body and the stretcher with a towel. First squeeze the eggs into a wash basin ("four major carps") or a large bowl (carp, crucian carp, roundhead bream, etc.) that has been wiped clean with water, then squeeze in a few drops of semen and stir evenly with your hands. For the eggs of the "four major carps", immediately add clean water to the basin, stir for 2 to 3 minutes to fertilize the eggs, and finally rinse several times or pour directly into the incubator for incubation; for carp, crucian carp, roundhead bream eggs, use yellow mud to de-stick and incubate, or sprinkle them into fish nests for incubation. The difference between semi-dry insemination and dry insemination is that the semen of the male fish is squeezed into or sucked from the anus with a straw and added to a beaker or vial containing an appropriate amount of 0.85% saline solution for dilution, then poured into a basin containing fish eggs and stirred evenly, and finally added clean water and stirred for 2 to 3 minutes to fertilize the eggs. Wet insemination is to squeeze the fish eggs and semen into a basin filled with clean water at the same time, stirring while squeezing to fertilize the fish eggs. This method is not suitable for sticky eggs, especially for fish eggs with strong stickiness. In production, dry and semi-dry artificial insemination are mostly used.

2. Artificial insemination, how much does it cost?

The cost of artificial insemination is about 20,000 to 30,000 yuan. The cost varies depending on the equipment of each hospital and the regional differences. There will also be certain differences in charges depending on the patient's condition. For artificial insemination, you should go to a local regular infertility treatment hospital and receive treatment under the guidance of a professional doctor, so that the chance of success will be higher.

3. How to artificially inseminate duck eggs?

Artificial insemination technology of ducks is one of the technical measures commonly used in the modern poultry breeding industry.

4. How many days does it take for artificial insemination to result in fertilization?

It usually takes about a week for fertilization to occur gradually after artificial insemination, so you should rest actively and observe the changes in secretions, but don't be stressed. It is recommended to go to the hospital for further examination in a few days. After more than 10 days, you can check the blood hcg results to determine whether you are pregnant. Do not eat irritating foods during this period, and pay attention to changes in secretions.

5. Is artificial insemination expensive?

Artificial insemination is not expensive, costing about 1,000 yuan per session. The specific cost may vary depending on each person's situation. Artificial insemination is also an assisted reproductive technology. It is a method of artificially injecting semen into the female reproductive tract to allow natural pregnancy during the female's ovulation period. Artificial insemination can use the husband's semen or the semen of a sperm donor.

6. Diet for artificial insemination?

After artificial insemination, you should pay attention to the following dietary considerations:

1. Pay attention to food hygiene, eat a balanced diet, have comprehensive nutrition, and eat less raw, cold, and spoiled food that can easily cause diarrhea, otherwise it will reduce the success rate of artificial insemination.

2. Eat a light diet, eat less spicy, irritating and greasy food, avoid smoking and drinking, and drink less tea, coffee, cola, etc., so as not to harm the embryo.

3. Change bad eating habits, do not be picky about food, do not eat a biased diet, do not overeat, and do not go on a diet just to lose weight.

4. Eat more nutritious foods, such as meat, eggs and soy products, and balance meat and vegetables.

5. Eat more easily digestible food. After artificial insemination, you need to rest in bed and reduce the amount of exercise. Some patients will experience decreased appetite and indigestion, so you should choose easily digestible food.

6. Eat more high-protein. After artificial insemination, patients should increase their protein intake, pay attention to nutritional balance, and eat more meals appropriately. They can eat some chicken, duck, fish, meat, eggs, soybeans and their products, which are high in protein.

7. What is the cost of artificial insemination of cattle?

The cost of artificial insemination for a cow is between 180 and 240!

8. What are the requirements for artificial insemination?

The conditions for artificial insemination generally include that the woman must have normal ovulation function, at least one side of the fallopian tube is unobstructed, and the endometrium can adapt to implantation; the man is only mildly or moderately oligospermic or asthenospermic. However, sperm with normal vitality can be extracted. Before artificial insemination, both men and women need to go to the hospital for a comprehensive examination, and artificial insemination can only be performed after a comprehensive evaluation after the examination.

9. What is the method of artificial insemination for sows?

The first time, although it is mature, it is not fully developed.

Therefore, it is best to use the method of two matings, which not only improves the conception rate, but also increases the litter size. The specific mating time is that the first mating is when the sow is receptive to mating (about 12 to 16 hours after the sow begins to estrus), and the second mating is carried out 24 hours later. Many pig farms often adopt a two-mating system, the first artificial insemination and the second natural mating.

10. What animal doesn’t look like a fish but is a fish?

The lancelet is known as the least fish-like fish.

Amphioxus, also known as Bai's lancelet, slug fish, double-pointed fish or sea hair, is a precious marine animal. Due to its extremely special morphological structure, it has the characteristics of both invertebrates and vertebrates. It is a typical representative of the transitional type from invertebrates to vertebrates. Therefore, it is highly valued by the biological community at home and abroad.

The appearance of lancelet is very strange and interesting. It has a very small body, flattened on the left and right sides, pointed and thin ends, and a spindle-shaped body. It is generally only 4 to 5 cm long.
