Artificial Insemination in Swine
The world population is 6.4 billion people approximately and is constantly growing. In this context, there is the expectation that it will reach 8.1 billion in 2030 and nine billion in 2050. In the next 25 years, this population growth will demand some 50% increase in food production. So, the world will be required some 53% increase in meat production, therefore elevating from 367 to 562 millio...
متن کاملArtificial Insemination in Veterinary Science
Artificial insemination (AI) is widely used by veterinarians and veterinary specialists in most domestic as well as wild animal species. Reasons for use of AI instead of natural matings are diverse and different for individual species. As in humans, AI can be used as a tool to increase conception rate in animals that have fertility problems. This is usually performed in companion animals, like ...
متن کاملEquine reproduction: advances in artificial insemination techniques
This article covers recent developments in the field of equine artificial insemination. Use of both chilled and frozen semen is discussed. For chilled semen, there is new information about what to do if the semen shipment is delayed and on maximising pregnancy rates in older mares by careful evaluation of the cervix. The number of motile sperm needed for insemination is reviewed in light of the...
متن کاملArtificial insemination and embryo transfer in mares.
Mares can be artificially inseminated with chilled or frozen semen to increase the revenue from their offspring. Embryo transfer can be used to produce more than one foal from a single mare per season. Recent advances in using equine follicle-stimulating hormone to induce superovulation in mares have stimulated research on preserving equine embryos. Equine embryos are usually collected on day 7...
متن کاملArtificial Insemination and Embryo Transfer in Goats
Artificial insemination (AI) is an important technology for improving animal production. Through consistent use of AI, herd genetics can be advanced at a rapid rate. While AI is a technology that enables the dissemination of selected male genetics, embryo transfer (ET) is a technology that enables the dissemination of selected female genetics and, by using ET, frozen embryos can be moved around...
