Administration of Meloxicam To Cows Experiencing Dystocia Does Not Increase the Incidence of Retained Placenta
(Georg Thieme Verlag, 2019) Kunz, F.; Koca, D.; Failing, K.; Wehrend, A.; Sendag, S.
Objective The post partum use of analgesics in cows has increased in consequence to society's increased awareness of animal welfare. However, it is known that the post partum administration of a subset of nonsteroidal anti-inflammatory drugs to cows may lead to an increased rate of retained placenta. Therefore, the aim of this study was clarify, whether a single administration of meloxicam to cows that experienced dystocia results in an increased rate of this disease. Material and methods The study was conducted in 63 Holstein-Friesian cows in 4 farms with random allocation into 2 groups: In animals of the treatment group (n = 27) a single subcutaneous injection of meloxicam (0.5 mg/kg) was administered within 2'8 hours after calving. The animals of the control group (n = 36) received the same volume of a bovine infusion solution (Amynin®, bovine infusion solution, Boehringer Ingelheim) subcutaneously. A clinical examination of the cows was performed on the day of parturition and on the 21st day post partum. Findings on the days in between were obtained by questioning of the farmers. The exact Fisher-test was calculated in order to test for statistical differences between the treatment and control groups. Results In cows of the treatment group, retained placenta was not observed more frequently than in cows of the control group. Conclusion and clinical relevance A single administration of meloxicam to cows that experienced dystocia does not increase the incidence of retained placenta. © Georg Thieme Verlag KG Stuttgart - New York.

Cervical Leiomyoma in a Dairy Cow During Pregnancy
(Elsevier Science Bv, 2008) Sendag, S.; Cetin, Y.; Alan, M.; Llhan, F.; Eski, F.; Wehrend, A.
In the present report we describe a case of cervical leiomyoma that was diagnosed at parturition in a Holstein cow. The tumor mass, which measured 25.5 cm x 21.5 cm x 14.5 cm in size and weighed 4.5 kg, was removed surgically. The tumor was solid, well circumscribed, whitish-pink colored, and encapsulated. The tumor was diagnosed as leiomyoma. The leiomyoma. had no adverse effects on pregnancy. This is the first report of a bovine cervical leiomyoma during parturition. (c) 2007 Elsevier B.V.

Comparison of Different Resuscitation Methods for Newborn Calves After Dystocia
(Georg Thieme Verlag, 2023) Homberg, J.; Sendag, S.; Koca, D.; Cetin, N.; Wehrend, A.
Objective This study aimed to compare the use of hand-powered vacuum pumps and the suspension by the hind legs within the scope of resuscitating newborn dystocial calves. Material and methods For this study, data were collected from 60 dystocial calves of different breeds. Various reanimation methods were employed to these calves immediately after birth. In group I (n=20), the hand-powered vacuum pump from HK-Rheintechnik (Neuwied, Deutschland) was used to remove mucus and amniotic fluid from the respiratory tract. In group II (n=20), the McCulloch Medical (Elmwood, England) hand-powered vacuum pump was used to remove mucus and amniotic fluid from the respiratory tract. In group III (n=20) 10 to 12 liters of cold water were poured over the neck of 20 calves immediately after birth. In addition, the calves were suspended by the hind legs via a gate or a pole, so that the head hung downwards vertically. The calves' Time to Sternal Recumbency (T-SR) of the calves was measured following the different resuscitation procedures in order to assess their vitality. In addition, the calves were examined segmentally at one-hour post natum. Furthermore, the calves were examined clinically on the seventh day of life. In addition, we investigated whether confounding variables such as calf sex, dam parity, obstetric intervention, and the season affected T-SR. Results T-SR ranged from 1.5 to 10.5 minutes. There was no difference between the three initial treatment procedures (p=0.07). However, the T-SR of calves treated with a hand-powered vacuum pump tended to be shorter. No statistically significant difference between the pulse rates (p=0.73), respiratory rates (p=0.13), and rectal temperature (p=0.65) of the animals in the three groups on the first and seventh day of life was evident. There was no statistically significant difference in the incidence of the diseases up to the seventh day of life between the individual study groups. Conclusion and clinical relevance The present study was able to show that the use of hand-powered vacuum pumps is at least equivalent to suspending calves. When using hand-powered vacuum pumps, the girth of the muzzle must be taken into account, as this can limit their utility. © 2023 Georg Thieme Verlag. All rights reserved.

Effect of a Single Meloxicam Administration on Newborn Holstein–friesian Dystocia Calves: Field Results From the First 10 Days of Life
(Veterinary World, 2022) Kunz, F.; Sendag, S.; Yildiz, M.; Failing, K.; Wehrend, A.
Background and Aim: Calves have increased morbidity and mortality rates after dystocia. One cause is pain during birth, which reduces their colostrum intake. The administration of nonsteroidal anti-inflammatory drugs (NSAIDs) may break this causality. This study aimed to determine the consequences of a single administration of the NSAID meloxicam to dystocia calves after birth. Materials and Methods: Fifty Holstein–Friesian calves born with dystocia from four dairy cattle farms were included in this study. The animals were randomized into two groups. The animals in Group I (n=25, treatment group) received subcutaneous 0.5 mg meloxicam/kg body weight 2-8 h after birth. The animals in Group II (n=25, control group) received a control substance (Amynin®, bovine infusion solution, Merial) with the same volume. The newborn calves were clinically examined on the 1st and 10th days of life. The information regarding the days in between was gathered by questioning the farmer. Results: There was a significant difference (p=0.04) only in calves with thin, mushy fecal consistency on the 10th day in the treatment group compared with the control group. Moreover, meloxicam had no effect on dystocia calves. Conclusion: Since NSAID administration did not produce a significant clinical effect, its necessity is questionable. Further studies should examine how modifying its application time would have an effect. The primary indicators of well-being, such as pain indicators in the blood, were not measured; however, these should be considered in subsequent studies. Copyright: Kunz, et al.

The Effects of Sildenafil Citrate and Vitamins A, C and E on Testicular Damage in Alloxan-Diabetic Rats
(Medwell Journals, 2012) Uslu, B.A.; Ilhan, F.; Gulyuz, F.; Karasu, A.; Tas, A.; Sendag, S.; Wehrend, A.
Sildenafil citrate is an active ingredient used successfully in the treatment of erection disorders caused by a variety of factors. The purpose of this study is to research the effects of Sildenafil citrate and vitamins A, C and E on testicular degeneration in rats with alloxan diabetes. The rats were divided into II groups; healthy control and diabetic groups. The diabetic rats were divided into X groups with ten animals in each group. Group I consisted of control diabetic rats that were given only distilled water, Group II was the diabetic group treated with glibenclamide; Group III was the diabetic group treated with insulin, Group IV was the diabetic group treated with Sildenafil citrate, Group V was the diabetic group treated with Vitamin A, Group VI was the diabetic group treated with vitamine, Group VII was the diabetic group treated with vitamin E, Group vni was the diabetic group treated with Sildenafil citrate and vitamin A, Group IX was the diabetic group treated with Sildenafil citrate and vitamin C and Group X was the diabetic group treated with Sildenafil citrate and vitamin E. Testis tissue samples were collected on the 3, 7 and 15th days of treatment in control and diabetic groups. In the histopathological examination of the testicles of diabetic rats, the seminiferous tubules and interstitium of testes in the control groups were normal and the complete spermatogenic cells in the seminiferous tubules were healthy and uniformly arranged. Severe degeneration and tubular atrophy was observed in the seminiferous tubules on the 3, 7 and 15th days in the group with induced alloxan diabetes given only distilled water (Group I). The lesions on day 3rd in the diabetic group given glibenclamide (Group II) were similar to those in the diabetic control group given only distilled water. All of the tubules had been affected by the 3rd day in group three which was given insulin. A small number of spermatogenic cells and giant cells were observed in some tubules. However, almost al of the degenerated tubules had healed on the 7 and 15th days. Even though, recovery on day 15th was very similar in Groups IV-X recovery was much more pronounced in Groups VIII-X beginning from day 3rd. © Medwell Journals, 2012.
