Therapeutics of Twin Pregnancies in Dairy Cattle

摘要

The series of eight articles (three original articles, three reviews and two com-ments) is presented by international leaders in the subject of twin pregnancies in dairy cattle. Cattle are a monotocous species, which means that under most circumstances, a successful pregnancy results in the birth of one calf. However, occasionally, the reproductive process in cattle results in the birth of twins. Twinning in dairy cows is not desirable as it can result in heavy economic losses. Based on multiple economic analyses conducted by numerous researchers, economic losses due to twinning are estimated to range between $59 to $161 per twin pregnancy [1].
