摘要： Postpartum uterine health in dairy cows is crucial for the maintenance of good reproductive performance. In order to improve uterine health and reduce puerperal intrauterine infection, 608 Holstein cows received a weekly PGF(2 alpha) protocol (3 i.m. injections of PGF(2 alpha), at 7,14 and 21 d postpartum). For comparison, 593 cows in the control group received injections of sterile saline at the same time. Uterine score at 14 d postpartum, the prevalence of endometritis at 21-27 d postpartum, and subsequent reproduction performance was evaluated. Cows in the treated group exhibited higher tonicity (P < 0.05) of the uterus, with less prevalence of endometritis (10.4%, 63/608 vs. 34.6%, 205/593; P < 0.001), and required shorter time to the first AI postpartum (67.5 +/- 3.4 d vs. 84.4 +/- 3.7 d, P < 0.05) and to pregnancy (114.5 +/- 5.4 d vs. 131.4 +/- 5.8 d, P<0.05). In conclusion, the present study demonstrated that uterine health in Holstein cows can be promoted while puerperal infection can be suppressed by this weekly postpartum PGF(2 alpha) protocol.
