The aim of this study was to record the course of peripartal udder oedema with ultrasonography in dairy cows and to investigate the therapeutic effects of diuretic furosemide. For this purpose, a device with a force sensor for the ultrasound probe was developed, which ensured the generation of data under similar pressure conditions and thereby repeatable and comparable results. In a pretrial with ten cows, ultrasonographic measurements were performed daily at four locations per udder quarter beginning 14 days ante partum until 14 d post partum. The main study included 50 dairy cows. The experimental group (n=25) received 500 mg furosemide intramuscularly on the day of calving, as well as on the first and second day post partum. The control group (n=25) was treated with 10 mL 0,9 % sodium chloride solution (NaCl) at the same timepoints. The experimental period was extended from 21 days ante partum until 21 days post partum and included 15 ultrasonographic measurements at three-day intervals. The measurements oedema between the group treated with furosemide and the control group did not differ. In conclusion, a method for the ultrasonographic measurement of udder oedema under comparable applied forces was established. The teat base turned out to be a suitable location to monitor the characteristic temporal course of udder oedema. In the present study, treatment with furosemide did not have a measurable, positive effect on the severity of the udder oedema post partum in the study animals. Finally, further studies with a higher sample size are necessary to confirm this relationship.
Matrices that can be collected non-invasively for quantification of a stress response in sheep have received little attention in the veterinary literature. This study examines the suitability of blood, tears and saliva for determining a stress response in sheep undergoing sham foot trimming on a tilt table. The cortisol concentration of blood, tears and saliva and the concentration of cortisol metabolites in faeces were measured in 13healthy Meat Merino ewes once a day for six days. Sham foot trimming on a tilt table was used as the stressor and was done during a one-hour period on day4; cortisol concentrations of blood and tears were measured at 0,10,20,30,40 and 60minutes. Cortisol concentrations of blood (maximum at 30minutes) and tears (maximum at 40minutes) increased during the procedure and then decreased. There were significant correlations between cortisol concentrations of blood and tears (p=0,04) during sham foot trimming (area under the curve, 0to60minutes). Over the entire 6-day study period, si 0,04) during sham foot trimming (area under the curve, 0 to 60 minutes). read more Over the entire 6-day study period, significant correlations were seen between the cortisol concentrations of blood and tears (r = 0,55; p.
Especially in regions with intensive cattle farming, paratuberculosis in ruminants can cause considerable economic losses for example through loss of sick animals, reduced milk yield and decreased reproduction performance. Although quantifying the actual economic losses is complex, this study attempts to quantify the losses caused by paratuberculosis in infected dairy farms in Switzerland by means of meta-analyses. For this purpose, in an elaborate selection process, data from 12 studies on milk yield and from three studies on the calving to conception interval were finally selected for further calculations. In addition, data from eight studies each on milk fat concentration and milk protein concentration were evaluated. For the meta-analyses, only studies in which «sick» (seropositive) and «healthy» (seronegative) animals based on the results of serum ELISA tests were compared at the individual animal level were considered. With a paratuberculosis prevalence of 5,99 % in cattle in Switzerland, a total lossof 305 days results in an economic loss of CHF 4 668 738,75 per year (95 % CI [CHF 1 571 188,69; CHF 7 725 011,07]; 4 304 577,13  € [1 448 635,97 €; 7 122 460,21 €]). Milk fat and milk protein content were not found to be significantly changed. Despite a large number of studies in the screening phase, it was not possible to calculate all types of losses attributable to paratuberculosis due to lack of comparability between the studies, which is essential for meta-analyses. Nevertheless, it was possible to carry out four different meta-analyses, the results of which give a first impression of the economic importance of paratuberculosis in dairy cows in Switzerland.
The impact of lameness on fertility in dairy cows has already been investigated, however predominantely in Holstein cows. The aim of this study was to evaluate the impact of lameness during the dry period, between calving and first service and between calving and conception (days open) on selected fertility traits in Austrian Fleckvieh cows. Locomotion scoring of dairy cows was performed during the course of routine performance testing in 2014 and 2015. Using the observed maximum locomotion score (MLSC) during pre- and postcalving periods, the cows were classified into three groups cows never lame (MLSC 1), cows that showed MLSC 2, and cows with MLSC ≥3 during these defined periods. Data sets of 3,998 lactations of 3,058 Austrian Fleckvieh cows from 97 dairy herds could be evaluated. In several statistical models the fixed effects of MLSC (1, 2, ≥ 3), farm, year and season of calving, parity*age class at calving, and early fertility disorders were considered for analysis of the traits days from calving to falving to conception and calving interval (CI), as well as the non-return-rate90 (NRR90). Mean lameness prevalence during the dry period was 19,43 %, and reached 27,70 % in the period between calving and conception. Lameness (MLSC ≥ 3) during the dry period significantly (P = 0,030) prolonged the period between calving and conception, and lameness (MLSC ≥ 3) during the period from calving to first service had a significantly detrimental effect on the periods calving to first insemination, days open and CI (P less then 0,001). Further, highly significant associations (P less then 0,001) in cows showing MLSC ≥ 2 during the period between calving and conception on all fertility traits were determined. Apart from lameness, farm, year and season of calving, parity*-age class at calving, early fertility disorders and, partly, the interaction of the latter two effects significantly (P.
The prevalence of osteochondral changes in the metatarsal growth plates of fattening bulls was investigated. Plantarodorsal radiographic views of the metatarsal region of 204 hind legs from 102 slaughtered fattening bulls were taken. Radiographic lesions in metatarsal growth plates were confirmed in selected cases using computed tomography (n=14) and histology (n=6). Radiographic criteria for growth plate lesions were axis deviations between the metatarsal bones and the digit, radiolucencies in the growth plate, increased bone density in the metaphysis, irregularities of the growth plate and marginal osteophytes («lipping»). The individual lesions were categorised as present/absent or 1 = slight, 2 = distinct, and 3 = severe. A weighted sum of these radiographic changes was generated for each growth plate and for each animal, and used for statistical analysis of the associations between husbandry factors and the occurrence of lesions. Almost all of the metatarsal bones had signs of osteochondral changes on the metaphysis (66,6 %) and radiolucencies in the growth plates (64,1 %). Computed tomography and histology revealed hyperplasia of the margins of the epiphysis and metaphysis, focal increase in bone deposits accompanied by incomplete ossification and irregular and widened cartilage columns of the growth plate. There were statistically significant associations between the weighted radiographic changes and slaughter weight, average daily weight gain, husbandry practices and production label. The prevalence of radiographic lesions indicative for osteochondrosis of the metatarsal growth plates of fattening bulls slaughtered at a local abattoir was high. The extent to which the distinct and severe lesions are associated with reduced production and obvious clinical lameness requires further study.A total of 649 children aged 7-13 years of age were recruited in a cross-sectional study in Tongxu County, China (2017) to assess the effects of interaction between single nucleotide polymorphisms (SNPs) in SOD2 and SOD3 gene and fluoride exposure on dental fluorosis (DF) status. Associations between biomarkers and DF status were evaluated. Logistic regression suggested that the risk of DF in children with rs10370 GG genotype and rs5746136 TT genotype was 1.89-fold and 1.72-fold than that in children with TT/CC genotype, respectively. Increased T-SOD activity was associated with a lower risk of DF (OR = 0.99). The rs2855262*rs10370*UF model was regarded as the optimal interaction model in generalized multifactor dimensionality reduction analyses. Our findings suggested that rs4880 and rs10370 might be useful genetic markers for DF, and there might be interactions among rs10370 in SOD2, rs2855262 in SOD3, and fluoride exposure on DF status.
Sleep problems are common in adolescence. We aimed to investigate sleep patterns and insomnia in Norwegian adolescents who have been in contact with child welfare services (CWS), both adolescents living in foster care (FC) and adolescents receiving in-home-services (IHS). Both groups were compared to youth who reported they were not receiving child welfare interventions.

Cross-sectional.

The population-based study youth@hordaland from 2012 in Hordaland, Norway.

About 9421 adolescents (53.8% girls), age range 16-19 years, were divided into 3 groups; IHS group (n=123), FC group (n=132), and control group (n=9166).

Self-reported information about demographics, detailed sleep patterns, sleep problems, and adverse life events.

Adolescents receiving IHS (vs. controls) had significantly shorter sleep duration, lower sleep efficiency, longer sleep onset latency (SOL), wake after sleep onset (WASO), and higher prevalence of insomnia. They had increased odds of insomnia (adjusted odds ratio [AOR]=1.77, 95% confidence interval [CI]=1.19-2.62) and SOL ≥ 30 minutes (AOR=1.95, CI=1.32-2.87). Adolescents in FC (vs. controls) reported lower sleep efficiency and longer WASO. When adjusting for sex and age, the associations did not substantially change. When additionally adjusting for adverse life events, the associations were considerably attenuated for both groups, and were no longer significant for the FC group.

Our results indicate a higher rate of sleep problems among adolescents receiving interventions from CWS, particularly those receiving IHS. Adverse life events accounted for a substantial part of the increased risk of sleep problems.
