Effects of equine chrionic gonadotrophin (eCG) on corpus luteum development and progesterone concentrations in Nelore cows. Author(s): VICENTE, W.; BERGAMASCHI, M. A. C. M.; VICENTE, W. R. R.; BARBOSA, R. T.; MACHADO, R.; BARUSELLI, P. S.; ALENCAR, M. M. de; BINELLI, M. This trial aimed to test eCG as an enhancer of the luteal function, as well as to evaluate the ability of eCG to delay or prevent luteolysis mechanism. A group of 32 mature, synchronized (CRESTAR@), l... ... Repository: BDPA Publication year: 2006
