Efecto de la Aplicación del Flavonoide en el Puerperio de la Vaca

The demand for food animal origin has generated a challenge to improve the productivity of the farms; so it has been tried to reduce the age at first calving, the interval between deliveries and the number of services per pregnancy. Therefore, reproduction is a vital factor for good reproductive efficiency in dairy farms; without the involution of the reproductive apparatus of the bovine female is insufficient, taking several days and affecting its period, so that to get this goal, the conception should occur before the 85th day postpartum. The objective to this work was to evaluate the effectiveness of flavonoid, in a dose of (1000g) in the puerperium, to restore uterine involution in Holstein cows. Twenty cows were selected between 2 and 3 years of age in the postpartum phase, which were randomly assigned to the treatment group and to the control group. In the treatment group a gynecological assessment was performed, determining the morphometry of the cervix, uterus and ovaries and percentage of involution, and then applied by uterine via flavonoid infusion (purified micronized flavonoid fraction - diosmin 1000 mg), at 10 days postpartum, and at 21 days the morphometric evaluation was again performed. In the control group to obtain the data, the evaluation was performed by ultrasonography between 10 days postpartum, as well as at 21 days postpartum to determine the morphometry of the reproductive system. These measurements were performed with an SIUI CTS 800 ultrasound with 5 MHZ linear probe. For the interpretation of the results of the experiment we used the statistical analysis of Student to detect the existence of significant differences between the means of a given quantitative variable in two groups of related data. Thus, the results of the present study show that intrauterine application of 100% flavonoids (1000 mg - diosmin) during bovine puerperium accelerated the involution of the reproductive tract. In addition, the involution of the cervix, uterus and the ovarian size ratio of the treatment group was accelerated, which was very satisfactory with respect to the control group; the average at 21 days postpartum was estimated to be 81.66% with respect to the control group, which was 62,5 %. Therefore, it is concluded that the results obtained in the present study regarding the use of flavonoid in the bovine puerperium in a dose of (1000g), show that its effect is directly proportional to the involution of the reproductive apparatus in treated Holstein Friesian cows.
