Checura CM, Beg MA, Parrish JJ, Reproduction Fertility and Development 22 (7): 1092-1099 Sep 2010. The effects of FSH, LH or both on follicular growth and intrafollicular free insulin-like growth factor (IGF)-1 and oestradiol were investigated in mares after the beginning of deviation (largest follicle >= 20 mm; Hour 0).
Khatib H, Monson RL, Huang W, Khatib R, et al., Journal of Dairy Science 93(5): 2244-2249 May 2010. The genotypes found to be associated with low bull fertility in this study have been reported to be associated with high milk composition in previous studies, providing molecular evidence for the antagonistic relationship between milk production and fertility observed for many years in different breeds of dairy cattle.
Checura CM, Beg MA, Gastal EL, et al., Reproduction in Domestic Animals 44 (3): 504-511 Jun 2009. A GnRH antagonist (Acyline) was used to study the role of FSH in early development of a follicular wave in 61 mares. Keywords: Gonadotropin-Releasing-Hormone; Luteinizing Hormone; Estrous Cycle; Circulating Concentrations; Dominant Follicle.
