Table 2 The number of toads spawning, the mean number of eggs produced per. spawning toad and total eggs spawned during the fertile period (11.5–17.5 hrs post-induction) for Bufo baxteri having received one or two primings. Data are expressed as the mean ± SE. There was a significant difference between one or two primings in the mean total number of eggs produced.

From: Hormonal priming, induction of ovulation and in-vitro fertilization of the endangered Wyoming toad (Bufo baxteri)

  No. toads spawning and egg production with one priming. No. toads spawning and egg production with two primings.
