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
Effects of hCG on progesterone concentrations and fertility in cyclic, lactating Alpine goats. Author(s): FONSECA, J. F. da; MAFFILI, V. V.; RODRIGUES, M. T.; SANTOS, A. D. F.; ROVAY, H.; PINTO NETO, A.; BRANDÃO, F. Z.; TORES, C. A. A. The objective of this study was to evaluate the effect of hCG administration on plasma progesterone concentrations in lactating Alpine goats during the natural breeding season. After detection of estr... ... Repository: BDPA Publication year: 2006
Effect of ovulatory follicle diameter and progesterone concentration on the pregnancy rate of fixed-time inseminated lactating beef cows. Author(s): PFEIFER, L. F. M.; LEAL, S. del C. B. de S.; SCHNEIDER, A.; SCHMITT, E.; CORRÊA, M. N. The objective of this study was to evaluate the influence of the ovulatory follicle diameter on the reproductive performance of lactating beef cows subjected to low progesterone fixed-time artificial... ...

Endogenous Progesterone Concentrations Affect Progesterone Release from Intravaginal Devices Used for Oestrous Synchronization in Cattle. Author(s): NERI, H. L.; PALHAO, M. P.; COSTA, D. S.; VIANA, J. H. M.; FERNANDES, C. A. C. Repository: BDPA Publication year: 2015
Plasma progesterone concentrations in Toggenburg goats submitted to estrous synchronization reusing autoclaved intravaginal progesterone devices. Author(s): BRANDÃO, F. Z.; SOUZA, J. M. G.; TORRES, C. A. A.; MAIA, A. L. R. S.; DENADAI, R.; OBA, E.; FONSECA, J. F. da Abstract: The aim of this study was to evaluate plasma P4 concentration in Toggenburg goats receiving autoclaved progesterone devices for estrous synchronization. Progesterone analysis allows us to in... ... Repository: BDPA Publication year: 2011
Effect of injectable progesterone on follicular development in lactating beef cows treated with estradiol plus a low-concentration progesterone device. Author(s): PFEIFER, L. F. M.; MAPLETOFT, R. J.; DARDAWAL, D.; SINGH, J. The effect of injectable progesterone was evaluated along with estradiol benzoate (EB) on the fate of the dominant follicle (DF) present in the ovary at the beginning of low progesterone-based TAI pro... ...
