Anormalidades na placenta bovina de clones e interferência no desenvolvimento embrionário fetal

Abstract

Bovines are very important animals for the population of today, as they are an excellent source of protein, with this, several researches are carried out in order to improve the quality and to achieve greater productivity of a herd. New techniques for production and reproduction are important for the advancement of the bovine cut which is growing more and more. An example of this is the cloning of animals of high genetic value, through the transfer of somatic nucleus (NT). This technique causes high loss of fetuses and mortality at birth due to a syndrome, related to the development of the placenta.
