The comparison of different intrauterine treatment efficiency in repeat breeder COWS

This study aimed to compare the effectiveness of different treatment options in subclinical genital tract infections, which is one of the causes of repeat breeder, a serious economic problem, in cows. The material of this study was 75 Holstein Fleckvieh breed, primiparous or multiparous, 2 to 8 years old cows. The cows diagnosed as repeat breeder were divided into three groups randomly; Group I (n=25): 10 ml cefquinome sulphate+5 ml dexamethasone sodium sulphate+10 ml 30% dextrose was applied intrauterine three times every other day; Group II (n=25): 100 mg rifaximine (13.4 gr) spray was applied by intrauterine route three times every other day to cows; Group III (n=25): The cows in this group subjected as a control group and any treatment did not apply. The synchronization program was applied to all cows following treatments, artificially inseminated, and the examinations were performed on the 35th day to detect pregnancy status. The pregnancy rates after the first artificial insemination were 32% (8/25), 20% (5/25), and 20% (5/25) in the groups, respectively (P>0.05). It was detected that the intrauterine administration of 10 ml cefquinome sulphate+5 ml dexamethasone sodium sulphate+10 ml 30% dextrose combination may increase the pregnancy number and affect positively the fertility in repeat breeder cows. The intrauterine drug combination used in Group I was found more effective than the intrauterine spray, including 100 mg rifaximin, which is frequently used in cows with a uterine infection. It was evaluated that the intrauterine drug combination used in the present study should be investigated with more animal material and with consideration of the different factors affecting repeat breeder cases in cows.
