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.
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.
The Effects of Levamisole Poisoning on the Haematological and Biochemical Parameters in Dogs
(M H Schaper Gmbh Co Kg, 2004) Gokce, HI; Gunes, V; Erdogan, HM; Citil, M; Akca, A; Yuksek, N
This study was designed to evaluate possible organ and system disorders associated with experimentally induced levamisole. poisoning in dogs. For this purpose, twelve clinically healthy dogs of different ages, sexes and breeds were used. They were divided into two equal groups (Group A and Group B) and given levamisole orally at a dose of 25 mg/kg of body weight daily for three days. The dogs in, Group B were also injected with atropin sulphate (0.04 mg/kg of body weight) subcutaneously (sc) 1 hour after each administration of levamisole. Routine clinical examinations were made and some haematological, biochemical and blood gas parameters were established at various times after administration of levamisole. The dogs in Group A developed severe neurological signs, gastric haemorrhage, bloody vomiting, colic, anaemia and four dogs died. In Group B these signs were mild and only one dog died. Levamisole poisoning was characterised by a significant reduction in the total number of red blood cells (RBCs), concentration of haemoglobin (Hb) and packed cell volume (PCV), and by anaemia. Peripheral blood pH, actual bicarbonate of plasma (HCO3), actual base excess (BE), partial pressure of oxygen (pO(2)) and saturated oxygen (O(2)SA-O increased in both groups of animals and these dogs developed metabolic alkalosis 48 hours after the first administration of levamisole. The results of the study also show that levamisole poisoning in dogs causes a significant increase in the activity of serum alanine aminotransferase (ALT) and of alkaline phosphatase (AP) and in the concentration of urea in both Group A and Group B. In the study, atropin sulphate reduced the severity of the clinical signs and the number of deaths, but it was not alone sufficient to remedy levamisole poisoning in dogs.
Follow-Up Ultrasonographic Examinations in Pregnant Bitches - Evaluation of Frequency and Significance of Embryo Resorption
(Schattauer GmbH, 2010) Sendag, S.; Dinc, D.A.; Celi, H.A.; Aydin, I.; Wehrend, A.
Objective: Follow-up ultrasonographic examinations in pregnant bitches to evaluate frequency and significance of embryo resorption. Material and methods: In 39 Kangal bitches the number of gestational sacs was measured and vitality of embryos/fetuses was evaluated by real time ultrasonography daily from the 15th till the last day of gestation. Results: Five bitches (12.8%) showed embryonic resorption and one of these bitches exhibited a complete resorption. Fetal death could be observed in four females and was related to a total loss of the litter. After the first evidence of embryonic death gestational sacs remained detectable for 8.6 ± 0.5 days.The number of embryos of bitches with (10.8 ± 1.8) or without embryo resorption (8.2 ±2.1) was statistically significantly different (p < 0.05). On the other hand there was no statistically significant difference within the number of embryos of bitches suffering fetal death and bitches without embryo resorption (8.2 ± 2.1 ) (p > 0.05). A relationship between litter size and gestational length could not be verified (r = 0.15; p > 0.05). Conclusion and clinical relevance: Due to these results the hypothesis is postulated that embryonic resorption is a kind of protective mechanism of the maternal organism against too large litter sizes. © Schattauer 2010.
Short Communication: Ultrasonographic Examination of the Abomasal Position in Dairy Cows During the Peripartal Period
(M H Schaper Gmbh Co Kg, 2005) Sendag, S; Seeger, T; Wehrend, A
The objective of this study was to document the abomasal position during the peripartal period by ultrasonographic measurement to get more data about the topographic dynamic. In 12 dairy cows the abomasal position was measured daily from the 5(th) day before calving up to the 5(th) day after calving by a transabdominal ultrasonographic examination (5 MHz convex transducer). The abomasal position was described by means of 3 measured distances: (a) the distance between the cranial margin of the abomasum and the Aphoid cartilage, (b) the distance between the right margin of the abomasum and the median line and (c) the distance between the left margin of the abomasum and the median line. Prepartal the abomasal position was different from the position during the postpartal period. Its position was more cranially (p < 0.05) and more right laterally (p, < 0.05). The left margin was not detectable at the left side of the mid-line ante partum. Directly after calving the left margin of the abomasum was found left of the linea alba (p < 0.05). These results show that there is a great influence of the gravid uterus on the abomasal position. The abomasum is positioned more cranially and more right lateral during the end of pregnancy. This position changes immediately after calving.
Vulvahypoplasia in an Alpaca Cria - First Case Report in Germany
(Schattauer GmbH, 2012) Schünemann, M.; Böhm, J.; Sendag, S.; Wehrend, A.
This is the first German case report of an alpaca cria suffering from a congenital vulvahypoplasia. Symptoms, diagnostics and therapy are described. The 24-hours-old cria was referred to the hospital due to reduced general condition and colic. The existent vulvahypoplasia led to impaired urination, causing further complications such as urovagina and urinary stasis up to the renal pelvis. Surgical construction of the rima vulvae cured the cria. As indicated by several cases published on the clinical picture of vulvahypoplasia during recent years, this con - genital deformation could become an increasing problem in the alpaca population. © Schattauer 2012.
