In newborn foals the absorption of colostrum immunoglobulins in the small intestine is maximal up to 8 hours after birth and then progressively decreases to become null after 24 hours post‐partum. Thus, equine practitioners need a simple, quick, inexpensive and reliable field test to identify foals affected by failure of passive transfer rather than an accurate method yielding quantitative results within the whole range of immunoglobulin concentrations.

评估用于检测新生马驹被动免疫失败的免疫比对法。

在新生马驹中，初乳免疫球蛋白在小肠中的吸收在出生后 8 小时内达到最大值，然后在产后 24 小时后逐渐减少至无效。因此，马从业者需要一种简单、快速、廉价和可靠的现场测试来识别受被动转移失败影响的马驹，而不是一种在整个免疫球蛋白浓度范围内产生定量结果的准确方法。
