Abstract | Cows suffered from retention of fetal membranes are at severe danger of developing puerperal metritis. Current study aimed to compare using local intrauterine application of chlortetracycline with oxytetracycline in treatment of dairy cows which suffered from retained fetal membranes considering clinical traits, milk production and prevention of puerperal metritis. Sixty-five Holstein Friesian cows suffered from retained placenta were divided into three groups. The first group (G1, n=25) was administrated 5 g of chlortetracycline through the local intrauterine route. The second group (G2, n=25) was administrated 5 g of oxytetracycline through the same route, while the third group (control group, G3, n=15) had no treatment. The results indicated that 21 cows of G1 group succeeded in expelling placenta within three days after treatment, whereas in G2, 15 cows had complete shedding of the placenta within five days post treatment. On contrary, G3 failed to completely expel the placenta within the same period. None of the cows developed puerperal metritis in G1 and G2 but 80% of control group suffered from puerperal metritis. The energy intake and milk production in G1 were significantly (p<0.05) higher among all the groups, while in G2 the energy intake and milk production presented a significant (p<0.05) decrease and the highest decrease of energy intake and milk production was in G3. Checking the time of involution of the pregnant uterine horn, time of involution of the cervix, time needed for the presence of the uterus in the pelvic cavity revealed a significant (p<0.05) difference in G1 when compared to G2 and G3. Vaginal discharge examination revealed that 15 cows of G1 had mucopurulent discharge which disappeared rapidly in the day 32 postpartum while 20 cows of G2 presented mucopurulent discharge which disappeared lately in day 37. In contrast, G3 have purulent discharge which needed a longer time (52 day postpartum) to disappear. Therefore, it is concluded that retained placenta can be treated effectively by chlortetracycline which also provide a good prevention against incidence of puerperal metritis.
