摘要：

A comparison was made between two different methods of reproductive management in the dairy cow. One protocol administered prostaglandin to open cows weekly; the other administered prostaglandin to open cows with a corpus luteum identified by rectal palpation. Survival analysis was used to analyze the data. Cows receiving weekly doses of prostaglandin had a 30% higher pregnancy rate (number of pregnancies per time) than the cows receiving prostaglandin based on rectal palpation of a corpus luteum. The average number of days to first insemination was shorter in cows given prostaglandin weekly.
