Técnicas y aplicación de la clonación en la producción bovina

Resumen

Cloning has managed to bring important aspects of animal reproduction due to the contributions and results obtained throughout history; from the cloning of Dolly the sheep in 1996, where researchers of animal production focused their studies in search of conservation, transmission and durability of desirable productive characteristics such as the quantity and quality of milk, muscle development, weight gain, resistance to diseases, among others. With cloning, animals resistant to diseases of productive interest have been obtained, such as mastitis and Bovine Spongiform Encephalopathy (BSE). We have then that the importance of cloning in the field of biotechnology applied to reproduction, lies in the fact that it allows the conservation of specimens of high genetic value and in the case of biomedicine, it makes it possible to obtain stem cells that give rise to the regeneration of damaged tissues and obtaining nutraceuticals. Over time, different cloning techniques have been developed, such as bipartition, cultivation and separation of blastomeres, nuclear transfer, paraclonation, among others. Cloning techniques include two directions, one horizontal and one vertical; Nowadays, the study of cloning has been directed towards ethics, where the use of these techniques for the creation of human beings with an identical genome is at stake.
