Advances in in vitro fertilization and in vitro culture techniques have allowed considerable progress in identifying physiological requirements of mammalian embryos. Parrish et al. (11) reported a major breakthrough on in vitro fertilization when his group identified heparin as an important factor for the capacitation of spermatozoa. Capacitation is necessary for fertilization of matured oocytes. During the precoculture era of embryos (prior to 1980), the development of early preirnplantation embryos was vary limited regardless of medium, medium supplement, gas atmosphere, osmolarity or pH used (7). Coculture techniques of fertilized oocytes using somatic cells during in vitro production, particularly of bovine …

Spider Lamb Syndrome (SLS) is a semi-lethal congenital disorder affecting the Suffolk and Hampshire sheep breeds. The clinical manifestations of the syndrome include severe skeletal and muscular abnormalities with long, fine-boned legs, curvature of the spine and nasal septum, minimal muscling and severe muscle atrophy. The affected animals have a difficult time walking and most lambs do not survive past the first six months of life. A single autosomal recessive gene causes the disorder. Researchers believe the SLS gene arose as a single source mutation in a popular Suffolk blood line in the 1970s. Heterozygous carriers of the SLS gene …
