As one of the oldest countries in China, the concept of conception of sows has been a passive “post-entry method†for thousands of years. It has not changed in the past millennium. This traditional way has long been unable to adapt to the ever-changing The social change, the fast-paced life, requires the fast-paced sows of the sows (produce more babies) so that our vast number of pig farmers are profitable. So how to improve the conception rate and birth rate of sows?
Let us first talk about why the traditional sow conception method does not produce high birth rates. Traditional insemination results in waste of semen reflux. Now the price of excellent boars and the cost of raising them are getting higher and higher. If you want to increase the number of offspring of excellent boars, you must adopt new technology. The traditional method of insemination wastes one-third of the semen. In order to avoid semen waste caused by semen reflow, the more advanced countries in the world are using the technology of intrauterine insemination.
Our vast number of pig-raising friends know that the two important reproductive physiology characteristics of sows are semen reflux and uterine phagocytosis, both of which have a great impact on artificial insemination. Since the phagocytosis in the uterus is essential to cause a large amount of sperm to be wasted, it is necessary to transport the sperm into the fallopian tube as quickly as possible to ensure high efficiency. The traditional technique is that the artificial insemination technique inserts the vas deferens into the posterior 1/3 of the cervix. When the cervix contracts, the semen enters and is blocked, causing some semen to flow backward. If you can avoid the problem of the cervix and let the semen directly enter the sow's uterus, you can avoid the return of insemination and lead to waste.
The new technique of intrauterine insemination is to pass the vas deferens through the cervix into the uterus. The benefits of intrauterine insemination are: reducing the waste of semen reflux and reducing the amount of semen per insemination. Reduce the amount of time spent on each insemination, reduce the number of boars and reduce the cost of breeding pigs. It also increases the number of offspring of good boars, increases the conception rate of sows, and the number of litters in sows.
So if you want to earn more money than others by raising pigs, you need to understand the new pig raising technology. The above is all about how to improve the conception rate and birth rate of sows, I hope to help everyone!
