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...

Ovulation-inducing factor (OIF/NGF) from seminal plasma origin enhances Corpus Luteum function in llamas regardless the preovulatory follicle diameter
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 ...

EFFECTS OF LONG-TERM NUTRITIONAL RESTRICTION ON PREOVULATORY LUTEINIZING HORMONE SURGE, LEPTIN, AND LUTEAL PHASE IN LLAMAS (LAMA GLAMA)
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)...
