Anomalías morfológicas en el síndrome de freemartinismo en bovinos

Resumen

The genetic alterations are one of the main problems in the productions, for that reason it is emphasized in a well-known genetic alteration, as it is the freemartinismo, it is a chromosomal anomaly that affects mainly the females product of heterosexual heterosexual births, this syndrome consists mainly in the fusion of the fetal membranes when two developing embryos are found in the uterus in parallel, this fusion predisposes to the formation of a vascular anastomosis, which will cause the bidirectional passage between hematopoietic stem cell embryos, causing the most known as chromosomal chimerism in the twins conceived, apart from stem cells, the hormonal component also takes center stage in this event, the antimullerian hormone produced by the male embryo passes into the circulation of the female, causing the agenesis or atrophy of the muller or paramesonefricos ducts, this will trigger a reaction perceived by the gonads of the female, which will cause a masculinization of the same, causing that when developing they produce antimulleriana hormone, and contribute to develop the representative characteristics of a fremmartin female. There are several diagnostic techniques for this syndrome, among them is the clinical examination, serology, cytogenetic evaluation, and as highly sensitive and specific techniques we have the polymerase chain reaction (PCR), with the help of these diagnostic methods we can recognize a freemartin animal precociously.
