Generation of Cloned Sheep Lacking Galactose-α1,3-Galactose and N-Glycolylneuraminic Acid Antigens. [PDF]
XenotransplantationABSTRACT Livestock have long been regarded as a potential source of donor organs to alleviate the global organ shortage for transplantation. Sheep have a similar anatomy to humans, providing the standard model for demonstrating biocompatibility and performance of biological heart valves to obtain regulatory approval for their use in transplantation ...

Superovulation Using CIDR in Holstein Cows.
Journal of Reproduction and Development, 1994 Three trials were conducted to investigate the superovulatory response of Control Inter-nal Drug Releasing device (CIDRR). Forty-six Holstein cows were divided into three treatment groups per trial; CIDRR without progesterone (P4) (Control), CIDRR containing 1.9 g P4 for 12 days (CIDRR-1) and the two CIDRR with P4 replacing with a new CIDRR on day 9 of

Is GnRH necessary at CIDR insertion using a 7-Day CIDR synchronization protocol for beef heifers?
Kansas Agricultural Experiment Station Research Reports, 2011 Introduction The EAZI-BREED CIDR is commonly used in estrous synchronization protocols for both beef heifers and cows. The label calls for insertion of a progesterone-impregnated controlled internal drug release (CIDR) for 7 consecutive days with an injection of prostaglandin F2α given a day before CIDR removal.
