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.
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.
Laboratory Diagnostics in the Urine of Young and Pregnant Ewes
(Schattauer GmbH, 2011) Sendag, S.; Cetin, Y.; Failing, K.; Wehrend, A.
Objective: The purpose of this study was to identify values for net acid base excretion (NABE) which are significant indicators of the acid-base equilibrium in pregnant and young ewes and to show its relationship with other parameters (base, acid, ammonium [NH4], base-acid quotient, sodium [Na], potassium [K], calcium [Ca]) in ovine urine. In contrast to dairy cows, data are rare on these parameters in ewes. Material and methods: A total of 99 animals were used in the study, consisting of 56 young (average of 5.6 ± 1.1 months) and 43 pregnant ewes (average of 35.2 ± 18.8 months). Measurement of fractional NABE in urine samples was carried out according to the method reported by Kutas. The pH value of the urine was measured with a laboratory pH meter. Na, K and total Ca were measured with a flame photometer. Results: For all values except Na significant differences occurred between urine samples of pregnant ewes and young ewes (p < 0.001). Base, acid, NH 4, NABE, K and Ca values were significantly higher in the urine of the youngs than in pregnant ewes. In young ewes, a strong correlation was found between NABE and base values while a weak correlation could be observed between pH and base values. In pregnant ewes, strong NABE-base, NABE-K, K-acid and K-base correlations were found as well as weak NH4-base, NH 4-NABE and NH4-K correlations. There was a strongly positive correlation between NABE and NH4 in pregnant ewes, while a weak negative correlation between those values was observed in young ewes. Conclusion: For the first time, we established values for NABE and certain other parameters in urine of pregnant ewes and young ewes. It was shown that the acid-base balance in pregnant ewes and young ewes can be evaluated by measuring NABE and certain trace elements in urine like in cattle.
