In order to determine relationships between the number of small follicles prior to superovulatory treatment and superovulatory response, a total of 55 superovulations were induced in Holstein cows. The ovaries were examined ultrasonographically once 0-1.5 days before the initiation of superovulatory treatment. The number of small follicles 3-6 mm in diameter on both ovaries before superovulatory treatment was found to be significantly correlated with the numbers of corpora lutea after superovulation (r = 0.440, P < 0.001), total ova recovered (r = 0.503, P < 0.001) and transferable embryos recovered (r = 0.482, P < 0.001). These results indicate that a single ultrasonographic examination of follicles 3-6 mm in diameter prior to superovulatory treatment can be utilized to predict superovulatory response.
为了确定超数排卵处理前小卵泡数量与超数排卵反应之间的关系，对荷斯坦奶牛共进行了55次超数排卵。在超数排卵处理开始前0 - 1.5天，通过超声检查卵巢。发现超数排卵处理前两侧卵巢上直径3 - 6毫米的小卵泡数量与超数排卵后黄体数量（r = 0.440，P < 0.001）、回收的总卵子数（r = 0.503，P < 0.001）以及回收的可移植胚胎数（r = 0.482，P < 0.001）显著相关。这些结果表明，在超数排卵处理前对直径3 - 6毫米的卵泡进行单次超声检查可用于预测超数排卵反应。
