Ovulation-inducing factor (OIF) is a protein present in llama seminal plasma that has recently been identified as beta-Nerve Growth Factor (NGF) and it induces not only a high rate of ovulation but also appears to have luteotrophic properties in this species. A 2-by-2 experimental design was used...

The objective of the study was to compare the pituitary and ovarian responses after intramuscular, intravenous, or intrauterine administration of P-nerve growth factor (beta-NGF) of seminal plasma origin (SP-NGF) in llamas. In experiment 1, mature female llamas with a growing follicle of 7 mm or ...

The objectives of this study were (1) to determine the effect of rabbit seminal plasma on LH secretion and ovulation using the llama animal model as an in vivo ovulation bioassay and (2) to determine the effect of llama or rabbit seminal plasma on ovulation induction in the rabbit model. In Exper...

The objectives of the study were to determine the effects of nutritional restriction on ovarian function in llamas. Mature female llamas were assigned randomly to a Control group, fed 100% of maintenance energy requirements (MER) (n = 8), or a Restricted group (n = 8) fed from 70% to 40% of MER u...

The objectives of the study were to determine the effect of seminal plasma beta-NGF on Corpus Luteum morphology and function and level of mRNA expression of steroidogenic enzymes. Llamas were assigned (n = 12/per group) to receive an intramuscular dose of: (a) 1 ml phosphate buffered saline (PBS)...

This study was designed to: 1) characterize the effect of ovulation-inducing factor (OIF) on pituitary LH secretion in ovariectomized (OVX) llamas; and 2) determine the effect of OIF on LH secretion in OVX llamas pretreated with estradiol-17 beta (E-17 beta) or estradiol benzoate (EB). In Experim...

The objective was to evaluate the developmental competence of cumulus-oocyte complexes (COC) collected by follicular aspiration in llamas treated with FSH or eCG. Llamas were assigned randomly to two groups (n = 16 per group) and treated, at the time of ovarian follicular wave emergence, with eit...
