| description |
ABSTRACT: To evaluate the effect of the temporary suspension of lactation (TSL) on the follicular dynamics, four suckling anestric Zebu cows were selected and evaluated by ultrasound three times a week; their estrus behavior was observed twice a day and the progesterone level was determined (RM) from the 30th postpartum day. The experiment was carried out under silvopastoril conditions in a Colombian dry tropical forest zone, with 450 in of altitude, 27 °C of temperature, and IMO mm of annual rainfall. At the 148' day of postpartum period, the cows were submitted to four consecutive days of TSL, and their follicular dynamics and progesterone levels were determined. The ultrasound images were recorded on video tapes to measure the dominant follicle (OF) and the greater subordinate follicle (SF) diameter, to calculate the follicular growth rate (GR) and the interdominance interval (ID) and to determine the ovulation and the corpus luteum formation (CL). The first day of the TSL, the cows were in different states of follicular dynamics. After the TSL, two cows, that had smaller number of follicular waves (P0.001) and greater DF diameter (P<0.05), presented estrus and ovulation with CL formation and 7.5 ng/ml maximum progesterone levels compared to the other two cows that did not ovulate, which increased the OF diameter in response to TSL It is concluded that the TSL induce the estrus and ovulation in anestric Zebu cows that previously presented follicular dynamics and dominant follicles development with diameter like an ovulatory follicle, and induces an increase of the OF diameter in anestric cows that previously presented follicular dynamics with underdeveloped DE. |

El experimento se realizó bajo condiciones de silvopastoreo en una zona de bosque seco tropical Colombia-no a 450 msnm, 27 DCP y 1.000 mm de precipitación anual. El día 148 postparto las vacas se sometieron a la SL, aislando sus crías por cuatro días. En las imágenes ultrasonográficas se midió el diámetro del folículo dominante (FD) y del folículo subordinado más desarrollado (FS); se calcularon la tasa de crecimiento folicular (TC) y el intervalo interdominancia (ID) y se determinaron la ovulación y la formación del cuerpo lútea (CL). Todas las vacas presentaron ondas foliculares desde el inicio del estudio pero ninguna presentó signos de estro antes de la SL. El día de inicio de la SL, las vacas estaban en diferentes estados de la dinámica folicular. Después de la SL, das vacas que habían tenido menor número de ondas foliculares (P<0.001) y folículos dominantes y subordinados de mayor diámetro (P<0.05), presentaron estro y ovulación con formación de CL y secreción de niveles máximos de progesterona de 7.5 nglml, en comparación con las otras dos vacas que no ovularon, las cuales solo incrementaron el diámetro del FD. La SL indujo el estro y la ovulación en vacas Cebú anéstricas que previamente habían presentado dinámica folicular y desarrollo de folículos dominantes con diámetro semejante al de un folículo ovulatorio y causó un incremento del diámetro del FD en las vacas anéstricas que previamente habían presentado dinámica folicular con FD subdesarrollados.application/pdfspaUniversidad de Antioquia, Facultad de Ciencias AgrariasMedellín, Colombiainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARTArtículo de investigaciónhttp://purl.org/coar/version/c_970fb48d4fbd8a85Atribución-NoComercial-CompartirIgual 2.5 Colombia (CC BY-NC-SA 2.5 CO)info:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by-nc-sa/2.5/co/http://purl.org/coar/access_right/c_abf2https://creativecommons.org/licenses/by-nc-sa/4.0/VacasAnestroFase folicularLactancia (animales)Ganado cebúCambio en la dinámica folicular en vacas cebú anéstricas sometidas a suspensión temporal de la lactanciafollicular dinamics changes on anestric zebu cows with temporary suspension of lactationRev.
