| 中文描述 | 一些動物對牛病毒性下痢呈血清反應陰性,會持續去除病毒.牛隻用從持續感染的公牛的精液來配種,於一些會降低受孕率但不是所有都是.雖然使用暫時感染的公牛授精不會總是導致血清轉化,而母牛使用持續感染的公牛精液來配種,幾乎總是血清轉化. |
| 英文描述 | Some animals seronegative to Bovine Virus Diarrhea (BVD) can persistently shed the virus. Cattle bred with semen from persistently infected bulls have had decreased fertility in some but not all studies. Cows bred with semen from persistently infected bulls almost always seroconvert, although insemination using semen from transiently-infected bulls does not always cause seroconversion. |
