These “Synch” protocols may include: Select Synch, OvSynch, CoSynch, and Modified Select Synch [2] The synchronization of the estrous cycle is commonly used in different industries, such as Dairy and Beef cattle. Synchronization allows these industries to improve management and nutrition of the cattle, while also decreasing expenses.
The farm raises Red Sindhi cattle and Kangeyam cattle in order to "encourage pure breeding and to preserve native breeds." [7] The Farm has an embryo transfer laboratory. Embryos from Red Sindhi cows are collected by multiple ovulation and embryo transfer technology and are transferred to cross-bred recipient cows by non-surgical method.

Donor embryo transfer has given women a mechanism to become pregnant and give birth to a child that will contain their husband's genetic makeup. Although donor embryo transfer as practiced today has evolved from the original non-surgical method, it now accounts for approximately 5% of in vitro fertilization recorded births.
Direct Frozen Embryo Transfer: Embryos can be frozen by SPF in ethylene glycol freeze media and transfer directly to recipients immediately after water thawing without laboratory thawing process. The world's first crossbred bovine embryo transfer calf under tropical conditions was produced by such technique on 23 June 1996 by Dr. Binoy S ...
In 1986, the first mouse was cloned in the Soviet Union from an embryo cell. [60] The first mouse from adult cells, Cumulina, was born in 1997 at the University of Hawaiʻi at Mānoa in the laboratory of Ryuzo Yanagimachi using the Honolulu technique. In 2008 Japanese scientists created a cloned mouse from a dead mouse that had been frozen for ...
A dozen more dairy herds in California have been stricken with bird flu as the virus continues to infect animals and humans around the U.S.. Nearly 700 herds in the state — or 71 percent of all ...
There have been difficulties using particular methods of cryoconservation with certain species. For example, artificial insemination is more difficult in sheep than cattle, goats, pigs, or horses due to posterior folds in the cervix of ovines. [13] Cryopreservation of embryos is dependent on the species and the stage of development of the embryo.
