Abstract
In this study, it was aimed to determine effect of postpartum routine intrauterin dimethyl sulfoxide (DMSO), DMSO + oxytetracycline and intramuscular PGF2α administration on fertility in cows. For this purpose, 150 cows were randomly divided into 3 groups for this study. Vaginal discharge and uterine size were scored with varying degrees from 1 to 3. DMSO group (n = 47) first in the postpartum interval of 25 to 35 days, secondly in the postpartum interval of 40 to 55 days, were twice administered 120 ml from 25% DMSO as intrauterine. In addition, PGF2α was administered at a luteolytic dose. For the DO group (n=46), first in the postpartum interval of 25 to 35 days in postpartum, secondly in the postpartum interval of 40 to 55 days, were twice 25% DMSO and 4 g oxytetracycline, all diluted with serum physiologic were administered 120 ml as intrauterine. Furthermore, PGF2α was also given at the luteolytic dose. To the prostaglandin group (n=42) PGF2α was given twice intramuscular luteolytic dose, firstly in 25-35 days and secondly in postpartum 40-55 days. Number of artificial insemination for one pregnancy, in cows with a vaginal discharge score of 1, was accepted significantly lower than a vaginal discharge score of 2-3 (p<0.05). In antibiotic group, pregnancy rates did not differ according to PGF2α and DMSO usage. In early postpartum period, the use of intrauterine antibiotics was concluded that the effect on fertility parameters was not different from PGF2α and DMSO. It was concluded that intrauterine routine use of DMSO improves fertility proportionally but more cows should be studied.

Abstract
Bu çalışmada, ineklerde postpartum rutin intrauterin Dimetil Sülfo Oksid (DMSO), DMSO + oksitetrasiklin ve intramuskular PGF2α uygulamalarının fertiliteye etkisini belirlemek amaçlandı. Bu amaçla 150 baş inek rastgele 3 gruba ayrıldı. Vaginal akıntıları ve uterus boyutları 1’den 3’e değişen ölçüde skorlandı. DMSO gurubuna (n=47) postpartum 25-35 gün aralığında ilki, postpartum 40-55 gün aralığında ikincisi olmak üzere iki defa serum fizyolojikle seyreltilen %25’lik DMSO 120 ml intrauterin olarak verildi. Ayrıca PGF2α luteolitik dozda uygulandı. DO grubuna (n=46), postpartum 25-35 gün aralığında ilki, postpartum 40-55 gün aralığında ikincisi olmak üzere iki defa serum fizyolojik ile seyreltilen %25’lik DMSO ve 4 gr oksitetrasiklin 120 ml intrauterin olarak verildi, PGF2α luteolitik dozda uygulandı. PG grubuna (n=42) 25-35 gün aralığında ilki, postpartum 40-55 gün aralığında ikincisi olmak üzere iki defa kas içi PGF2α luteolitik dozda uygulandı. Vaginal akıntı skoru 1 olan ineklerde gebelik başı tohumlama sayısı akıntı skoru 2-3 olanlara göre anlamlı derecede düşük bulundu (p<0.05). Antibiyotik kullanılan grupta gebelik oranları PGF2α ve DMSO kullanımına göre farklılık göstermedi. Erken postpartum dönemde intrauterin antibiyotik kullanımın fertilite parametrelerine etkisinin PGF2α ve DMSO’dan farklı olmadığı sonucuna varıldı. DMSO’nun intrauterin rutin kullanımının oransal olarak fertiliteyi iyileştirdiği ancak daha fazla sayıda inekte çalışılması gerektiği sonucuna varıldı.
