Ultrassonografia modo doppler na reprodução de vacas de corte

Abstract

The aim is to compile scientific information on the use of Doppler in reproduction in beef cows, focusing on the benefits of its use in IATF and TETF programs. Currently in animal reproduction are widespread several biotechnologies, which make the improvement of production, with greater genetic value of animals and quality of the product available on the market. Ultrasonography emerged as a contribution to these biotechnologies, optimizing the use of them, for being a fundamental tool in animal reproduction, promoting non-invasive diagnosis, accessing structures of the reproductive system of the female, optimizing the biotechnologies already widespread. In Veterinary Medicine applied helps mainly in determining the diagnosis of pregnancy and evaluation of ovarian dynamics. The association of Doppler ultrasonography with conventional ultrasonography enabled further advances in the vascular architecture of the reproductive system. In real time, Doppler ultrasound estimates the functionality of structures such as endometrium, follicles and corpus luteum through blood perfusion. Thus, this tool is efficient, collaborating positively in genetic improvement programs, such as artificial insemination at fixed time and embryo transference at fixed time, especially in the early gestational diagnosis in resynchronization protocols and in the selection of receptors by evaluating the functional of the corpus luteum, observing the vascular pattern.
