Mechanism of LH release after peripheral administration of kisspeptin in cattle
Fig 1
Experimental model used in Experiment 2.
Emergence of a new follicular wave (Day 0) was induced by follicular ablation (FA) three days after ovulation, and an intravaginal progesterone-releasing device (CIDR) was inserted immediately after follicle ablation and left in place for 13 days. Luteolytic doses of a prostaglandin F2α analog (cloprostenol) were given on Day 3.5 and 4. Ovarian ultrasonography was performed daily during the experiment. Blood collection and treatment administration was done on Day 6.
