Freemartinismo en ganado bovino

Resumen

The Freemartin syndrome is one of the reproductive abnormalities, whose consequence is the decrease in the reproductive efficiency of the females produced by twin heterosexual births, which generate an irreversible sterility and the implantation of problems in the economic performance of the bovine herd. The frequency of this genetic aberration depends on heterosexual twinning in the population, the most common cause of this pathology is the fetal anastomosis that occurs in the early stages of pregnancy, of difficult early interpretation and high costs if the newborn freemartin is not identified. The objective of the present review is to compile updated information on the syndrome, its frequency of presentation, pathophysiology and consequences.
