Indução de múltiplas ovulações em éguas utilizando baixas doses de acetato de deslorelina
(Universidade Estadual Paulista (Unesp), 2011)
O presente estudo objetivou verificar a utilização do acetato de deslorelina indução de dupla ovulação em éguas. No experimento 1 as foram utilizados 16 ciclos de 8 éguas, que foram tratadas com 100 μg de acetato de ...
Managing the dominant follicle in high-producing dairy cows
(Nottingham Univ Press, 2010-01-01)
Reduced reproductive efficiency has been reported in high-producing dairy cows. Sources of reproductive inefficiency include decreased expression of estrus, increased diameter of the ovulatory follicle and reduced fertility ...
Diagnóstico de gestación doble y ablación manual de una de las vesículas embrionarias en un equino
(Bogotá : Universidad de Ciencias Aplicadas y Ambientales, 2020Facultad de Ciencias AgropecuariasMedicina Veterinaria, 2020-05-22)
En reproducción equina, la ocurrencia de ovulación múltiple en yeguas, generalmente conduce a preñeces dobles, esta condición fisiológica es denominada como gestación de alto riesgo, ya que puede generar complicaciones ...
LH response of seasonally anovular Corriedale ewes acutely exposed to rams and estrous ewes
(Elsevier Science, 2008-01-15)
Serial blood sampling before and after exposing four anovular Corriedale ewes to a group of rams and estrous ewes during the non-breeding season revealed a pattern of LH secretion similar to that previously observed in ...
A new presynchronization system (Double-Ovsynch) increases fertility at first postpartum timed AI in lactating dairy cows
(ELSEVIER SCIENCE INC, 2008)
This study evaluated a novel presynchronization method, using Ovsynch prior to the Ovsynch-timed AI protocol (Double-Ovsynch) compared to Presynch-Ovsynch. Lactating Holstein (n = 337) cows, were assigned to two treatment ...
Reduction in size of the ovulatory follicle reduces subsequent luteal size and pregnancy rate
(Elsevier B.V., 2001-07-15)
We hypothesized that reducing the size of the ovulatory follicle using aspiration and GnRH would reduce the size of the resulting CL, reduce circulating progesterone concentrations, and alter conception rates. Lactating ...
