[QUOTE="randiliana, post: 635933, member: 2308"] Here are some quotes I have found that relate to contracted tendons From [u]The Nature of Bovine Virus Diarrhea in Cattle John H. Kirk1, Robert Moeller2, Dale Moore3[/u] "Typical effects from BVDV infection are determined by the pregnancy status of the cow. Infections prior to about 45 days of gestation may result in early embryonic death. Infection between 45 and 130 of gestation may produce fetal death or persistently infected calves may result. Congenital defects such as cerebellar hypoplasia, [b]contracted tendons[/b], hydranencephaly and hydrocephalus may form when infection takes place between 100 and 150 days of gestation. Abortions may occur with infection from 100 to 270 days of pregnancy. This is also the time frame for congenital infections to occur. Still births occur with infections during the last week or so of pregnancy." From the Merck Vetrerinary Manual [url=http://www.merckvetmanual.com/mvm/index.jsp?cfile=htm/bc/90206.htm]http://www.merckvetmanual.com/mvm/index ... /90206.htm[/url] "[b]Contracted flexor tendons [/b]are probably the most prevalent abnormality of the musculoskeletal system of newborn foals and calves. An autosomal recessive gene causes this condition. In utero positioning may also affect the degree of disability." From Iowa Beef Centre Congenital Defects in Cattle R. R. Schalles, Department of Animal Sciences and Industry, Kansas State University H.W. Leipold, Department of Pathology, Kansas State University R. L. McCraw, Department of Animal Science, North Carolina State University "Flexed pasterns (contracted flexor tendons) is usually caused by a large fetus developing in a small uterus. However, both crippled calf and flexed pasterns can also be genetically caused, inherited as simple recessive traits." [/QUOTE]
