Beef cattle is a kind of cattle that mainly produces beef. It not only provides people with meat products, but also provides people with other non-staple foods. In our country, there are common fine breeds such as Simmental cattle, Charolais cattle, and Limuzan cattle. Artificial breeding of cows is an important means to improve the herd. Let's take a look at the artificial breeding technology and precautions of beef cattle!
Beef cattle is a kind of cattle that mainly produces beef. It not only provides people with meat products, but also provides people with other non-staple foods. In our country, there are common fine breeds such as Simmental cattle, Charolais cattle, and Limuzan cattle. Artificial breeding of cows is an important means to improve the herd. Let's take a look at the artificial breeding technology and precautions of beef cattle!
1, beef cattle born after 10 to 12 months of age, hybrid beef cattle 12 to 15 months of age, the bull can produce with fertilization ability, the cow can discharge mature eggs, then mature. Maturity in no way means that it can be used for reproduction, as the beef cattle are not yet fully developed and if carried outTheoryNot only the growth and development of the beef cattle itself is affected, but the quality of the offspring is also inferior.
2. The body of beef cattle has the inherent shape of adult beef cattle, which is called body maturity. When the body is mature, it can participate in breeding. Generally, the body maturity of beef cattle is 1.5~2 years old, that of hybrid beef cattle is 2.5 years old, and that of dairy cattle is about 15~22 months old. However, due to differences in beef cattle breeds, feeding management, and climatic conditions, the possibility of promoting and delaying body maturity is high.
Artificial breeding technology of beef cattle
1. Cow Baoding: The inseminate cow will be brought into the mating rack for Baoding. Baoding may not be required when the operation is skilled. In addition, the tail of the cow is hung up with a string, and then the vulva of the cow is washed with clear water. It can also be disinfected and dried with 2% lysol or 0.1 potassium permanganate solution.
2. Semen Thawing: Prepare warm water at 37~42 ℃, take out a thin tube of frozen semen from the liquid nitrogen tank with tweezers and immerse it in warm water, shake it gently for about 10 times, wipe off the water droplets on the surface of the thin tube, cut off the seal, put the embolized end down into the gun, put the jacket on and tighten.
3. Insemination method: One hand is inserted into the rectum to grasp the cervix across the intestinal wall, the arm of the hand is pressed down to open the vulva, and the other hand is inserted downward after being inclined from the vulva for a period of time, until it is inserted to the junction of the cervix and the uterine body, and the vas can be withdrawn with the injection. In order to ensure the conception rate, compound once every other day.
1. Initial mating age: large beef cattle breeds such as Simmental cattle and Charolais cattle must be over 1.5 years old, with a skeleton and weight of over 70% of adult cattle, while small beef cattle breeds or native cattle must be over 1 year old, with a skeleton and weight of over 60% of adult cattle.
2, frozen sperm selection: smaller cows or first-time cows should not choose more than its size, weight 2 times the bull, larger cows or cattle can use larger purebred bulls or frozen sperm for mating, but the bull size, weight is still not more than 3 times the cow.
3. Mating Time: Ovulation time is not easy to master in the actual mating process. Mating is generally carried out according to the time of estrus. Mating is carried out in the afternoon for estrus in the morning (fear of crossing) and in the morning for estrus in the afternoon. In order to improve the mating rate, compound can be used.
4. Pre-match inspection: Both bulls and cows must undergo health inspections before mating to prevent cross-infection. In the case of epidemic disease, it is not suitable for mating and should be eliminated directly.
5. Equipment disinfection: In the case of artificial insemination and mating, the insemination equipment must be checked before insemination to see if it can be used normally. At the same time, strict disinfection should be carried out to prevent cross infection.
