I am not very sure but basically it is a non-genetic disorder and is caused either by infections or mal handling of cows
Neospora caninum is a protozoan parasite that is emerging as an important infectious cause of weak calves and abortion in cattle. Besides this, temperature, physical injuries, hot soup, and possible genes related to RBC dysfunctions may lead to abortion in cows. Role of genes in abortion can not be denied, because endometrium and follicle attachment and formation of trophic villi are disturbed due to defaulted proteins which distort the functional and structural attachment of chorionic epithelium in zonary or cotyledonary placenta found in animals.
Do you mean, "can I use a blood sample to test for genetic causes of abortion in dairy cattle?" The answer then is yes, though you are limited to testing for those genetic disorders that have already been identified and for which there is a commercial test available. Examples in Holstein cattle include DUMPS, CVM and brachyspina. Additionally, in breeds that have extensive genomic testing data, a number of lethal haplotypes have been identified. These SNP combinations never occur in the homozygous form in live cattle but cattle owners can test their cows for the presence of these SNPs as heterozygotes and avoid using bulls that have them as well. Because these lethal haplotypes are discovered by testing for their absence in the homozygous form in normal cattle, they cannot be definitively said to cause abortion. The pathology may involve conception failure, abortion (at any stage) or stillbirth.
