CATDOLL : CATDOLL: Reasonable use of fish oxytocin?

1. How to use fish oxytocin reasonably?

The drugs currently used to induce spawning using dried fish include: the commonly used fish ovulation induction No. 2 (LHRH-A2), fish chorionic gonadotropin (polysexual hormone, HCG), chorionic gonadotropin type A, chorionic gonadotropin type B, fish ovulation induction No. 3 (LHRH-A3), diometron (DOM), fish pituitary gland (pituitary gland, PG) and a variety of complex high-efficiency oxytocin, but the most commonly used ones are fish ovulation induction No. 2 (LHRH-A2) and fish chorionic gonadotropin (polysexual hormone, HCG).

For fish with low spawning rate and low total spawning volume, such as loach, Chinese spiny target (Qingbo) and other medium and high-end fish, dioic acid (DOM) and pituitary gland (PG) should be added on the basis of using LHRH-A2+HCG, and the effect will be doubled.

For common fish, such as grass carp, silver carp, bighead carp, carp, crucian carp, etc., LHRH-A2+HCG is effective, and there is no need to add other oxytocin drugs to reduce production costs. Grass carp using LHRH-A2 alone, silver carp using chorionic gonadotropin type A alone, and bighead carp using chorionic gonadotropin type B alone are sufficient to achieve the purpose of smooth spawning.

2. How to choose and use fish oxytocin?

Commonly used oxytocin hormones include: carp and crucian carp pituitary gland (PG), human chorionic gonadotropin (HCG), luteinizing hormone releasing hormone analogue (LRH-A), dioestrogen (DOM), reserpine (RES), etc.

3. What are the commonly used fish oxytocins?

Commonly used fish oxytocin agents include the following: 1. Oxygen: Oxygen is a hormone-based oxytocin agent, which is often used to increase the spawning rate of female fish and promote the maturation of follicles. Common oxytocin agents include synthetic GnRH (growth hormone-releasing hormone), hCG (human chorionic gonadotropin), etc. 2. Clonidine: Clonidine is an anesthetic, which is often used in the process of fish oxytocin. It can inhibit the physiological response of fish, reduce the stress response during spawning, and increase the spawning rate. 3. Ovaprim: Ovaprim is a commercial oxytocin agent made of a mixture of GnRH and hCG. It is often used in artificial breeding of marine fish and can effectively promote follicle maturation and spawning. 4. Acacetin: Acacetin is a plant extract with an oxytocin effect. It is often used in artificial breeding of freshwater fish and can increase the spawning rate of female fish and promote the maturation of follicles. It should be noted that the use of fish oxytocin agents should comply with relevant laws, regulations and technical specifications to avoid adverse effects on the environment and fish. At the same time, the use of oxytocin requires strict adherence to the instructions to ensure the effectiveness of oxytocin and the health and safety of the fish.

4. What is the basic principle of fish oxytocin?

The principle is to use a combination of physiological and ecological methods to directly inject oxytocin (PG, HCG or LRH-A, etc.) into the fish, replacing the effect of the gonadotropin secreted by the fish's own pituitary gland, or replacing the effect of the hypothalamus releasing LRH, which triggers the pituitary gland to secrete gonadotropin, thereby promoting oocyte maturation and spawning. Among fish oxytocin, the main components of the pituitary gland and HCG are FSH and LH. After entering the blood circulation of fish, they directly act on the gonads of carp, promoting gonadal maturation and spawning;

5. Why do we use carp pituitary gland as fish oxytocin?

Isolation, water change, oxygenation, temperature increase by 28 degrees~

The above are all methods that can artificially induce labor~

The water you change should be exposed to the sun and have yellow medicine added~ The survival rate of tropical fish is very low when the temperature is low~ If it is a large goldfish, you can use the pituitary hormone of carp to promote~

6. How long does it take to give birth after induction of labor?

If you use oxytocin, the labor process will progress more smoothly, but everyone's reaction after taking the medicine is different. If there is no obvious change after taking the medicine, it means that you are not sensitive to the medicine. So after taking the medicine, you will not have a normal delivery in a short period of time. It needs to be decided based on each person's specific situation. Some people use oxytocin, and the progress will be smoother in a short period of time, and it may be over in two or three hours.

7. Fish induced spawning technology?

When selecting female broodstock, lay the fish flat with the membrane part facing upwards, slightly above the water surface. If the abdomen is swollen and soft, especially if the lower abdomen is slightly drooping on both sides, the midline is slightly concave, the ovary outline is obvious, and the reproductive opening is slightly red and slightly protruding, then the broodstock can be used for induced spawning. The method for selecting male fish is to gently squeeze the lower abdomen of the fish with your hands. If there is milky white thick semen flowing out of the reproductive opening and it quickly disperses after entering the water, then it can be used for induced spawning.

8. How to induce labor in cows?

First, inject lubricants and other substances into the cow's vagina, and then slowly massage the outside of the vaginal opening manually to check on the cow's condition and see if it is going well.

Second, if the calf cannot come out of the vagina, use your hands to open the vaginal opening, and after the calf's feet are exposed, tie the calf's feet with a rope and pull until it is slowly pulled out.

Thirdly, it is best to take care of the cow during the delivery period, walk more before delivery, and provide adequate nutrition to avoid lack of strength during delivery. This is the most important factor.

9. How to induce labor in hamsters?

Quiet and comfortable environment

Place the cage in a quiet corner. It is best not to make too much noise at home. Give the mother mouse a quiet and solitary environment, otherwise her mood will easily fluctuate and she will become irritable and angry. The mother mouse needs a clean living environment during pregnancy, but the cage should not be cleaned during feeding the baby mice. At the same time, the most important point is that male and female mice must be raised separately.

2. Clean up toys

During pregnancy, it is best to remove all running wheels, swings, etc. in the cage, leaving only the kettle, nest, and food bowl. The bathroom should also be removed. However, special circumstances can be considered for damsel-in-law mice, because damsel-in-law are relatively irresponsible mothers compared to three-line and bear mice. damsel-in-law mothers are too nervous and have a lot of nerves. You can consider leaving the running wheel in the cage, but please try to lower the height of the running wheel as much as possible to relieve the anxiety of the mother mouse.

3. Don’t Pay Too Much Attention

When we find that our hamster is pregnant, we should not disturb it too much because of curiosity. They are sensitive to objects, and they are pregnant, so their emotions may be affected at any time. Most importantly, we must not touch the baby hamsters after giving birth. We just need to ensure that there is sufficient water and food and a comfortable environment. Even the hamsters are more playful after giving birth and will not take care of the children wholeheartedly. At this time, we do not need to rush and participate too much. Because the nature of hamsters is like this, the survival rate of baby hamsters is relatively low, but this is a common natural law. If we intervene too much, it may cause abandonment.

10. Can hawthorn induce labor?

Although hawthorn can cause uterine contraction, the effect is not that great. In other words, eating hawthorn before delivery does not necessarily have a particularly obvious effect. It requires medication treatment, such as using some oxytocin, which can promote uterine contraction and the progress of labor. In addition, the mother's breasts need to be massaged, which can also promote uterine contraction.
