Diagnóstico ultraprecoz de gestación en bovinos lecheros con la técnica DOPPLER.

Abstract

In the present investigation, an ultra-early pregnancy diagnosis was carried out in dairy cattle using the Doppler technique. To evaluate the effectiveness of the technique through the artificial insemination method, a total of 30 cows were analyzed. The methodology focused on the analysis of measures of central tendency; therefore, a descriptive statistic was employed for the analysis of the variables. Sensitivity values of (93.33%), specificity (13.33%), fertility (93.33%), accuracy (92.4%) and reliability (86.58%) were established; Likewise, it was determined that 7 cows that obtained the largest size of the corpus luteum being 35mm, while the blood supply of the corpus luteum at 22 days post insemination obtained a result of 100% in 22 cows. Finally, it is observed that 2 cows reached the highest levels of progesterone in milk with 25.84 and 21.993 ng / ml, with which it is demonstrated, by means of the present study, that an ultrasound is an easy and reliable method that, in addition to being a non-invasive technique, it has generally been used to study the reproductive organs of cattle and many other species. Its use allows in vivo visualization of internal organs, in addition to monitoring the reproductive life of the cow.
