摘要: As part of the development a germplasm biobank to preserve genetic diversity threatened wood bison (Bison athabascae), 2 × factorial study was designed determine effects ovulation induction agent and follicle maturity on ovulatory response in during anovulatory season. Bison (n=32) were assigned randomly four groups (n=8/group) treated with either pLH or hCG when growing dominant 8-9 mm ≥10 mm. The ovaries examined daily by ultrasonography timing ovulation, 7 days post-treatment assess CL development. proportion that ovulated greater than ([15/16] 94% vs. [8/16] 50%; P<0.05), at time treatment (88% 56%; P<0.05). interval from 37.0 ± 1.3h not affected size. However, synchrony tended be (P=0.10) group group, ensuing corpus luteum larger (15.3 0.43 13.4 0.36; In conclusion, both inducing size influenced Treatment more effective for bison, effect given
