The aim of this study was to determine urinary shedding of leptospires in healthy dogs and to identify the shedded leptospire species. Furthermore, antibody presence against leptospires was evaluated. In a prospective study urine samples of 200 healthy dogs from Upper Bavaria were randomly collected and evaluated by real-time polymerase chain reaction (PCR) specific for the lipL32 gene of pathogenic Leptospira (L) spp. Positive samples were further character- ized via multilocus sequence typing (MLST) to identify the Leptospira species. Microagglutination test (MAT) was performed to determine serum antibody titers. Three of 200 urine samples were found to be PCR-positive resulting in a urinary shedding prevalence of 1.5% (95% confidence interval 0.3-4.5%). All three dogs had been vaccinated before with a bivalent vaccine, covering the serogroups Canicola and lcterohaemorrhagiae. One dog shed leptospires of the species L. borgpetersenii, and two of the species L. interrogans. Of all dogs, 17.0% had antibody titers ≥ 1:100, and 3.5% titers ≥ 1:400 to serovars of non-vaccinal sero- groups. Healthy dogs that shed leptospires represent a possible risk for humans and other animals. The study emphasizes the importance of general hygiene measures in veterinary practice while handling urine of all dogs, and the use of vaccines that protect against a broader range of serogroups and that prevent urinary shedding.","PeriodicalId":8761,"journal":{"name":"Berliner und Munchener tierarztliche Wochenschrift","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34502017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beside overall antimicrobial use, specific substances listed by the WHO as \"highest priority critically important antimicrobials\" (HPCIAs)--these include fluoroquinolones, macrolides, 3rd and 4th generation cephalosporins, as well as glycopeptides--have been placed under specific restrictions and should only be applied in particular cases according to strict indication criteria. In this study, the consumption of antimicrobial substances on Austrian dairy farms was evaluated quantitatively. The data covered 8,027 prescription records on the use of antibiotics on 465 dairy farms. Eleven veterinary practices provided data from between four to 27 months during the period from 2008 to 2010 and the total consumption of antimicrobials was estimated. The amount of active substance(s) in grams used per livestock unit (g/LU) per year and the number of product-related daily doses used per livestock unit (n PrDD(LU)/LU) per year were determined as units of measurement. These parameters were estimated by applying Monte Carlo simulation techniques, respecting variances in annual working days of the veterinary practices as well as variances in the proportion of non-treated populations. Total antimicrobial consumption in the population-at-risk was determined to be 2.59 g/LU and 1.30 PrDD(LU)/LU per year. HPCIAs were used at a proportion of 24.6% (0.31 PrDD(LU)/LU) of the total consumption of antimicrobials for systemic and intramammary use. Of these, 3rd and 4th generation cephalosporins were most frequently administered, particularly for the treatment of mastitis and foot diseases. The total consumption of antimicrobials in Austrian dairy cattle production is negligible compared to their use in pig and poultry production systems. However, the use of HPCIAs, especially 3rd and 4th generation cephalosporins, should be minimised further.","PeriodicalId":8761,"journal":{"name":"Berliner und Munchener tierarztliche Wochenschrift","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34610093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Processes to ensure and optimize economic viability of dairy farming are becoming more important in comparison to treatment of single ill animals. Amongst others, rectal palpation skills are crucial for proper fertility management, rapid and correct diagnosis of early pregnancies, and recognition of cycle or fertility problems. The aim of this study was first to objectively analyse the effectiveness of prevailing teaching methods for rectal palpation of the reproductive tract during the students' \"agricultural internship.\" Simultaneously, the effectiveness of the use of two teaching simulators prior to the first hands-on experience with live animals was compared with proving just theoretical instruction. The results showed that students acted with more confidence when they were trained in groups of three to five. In particular, the subjective as well as the objective training success was greater for those students, who trained with a simulator (Haptic Cow®, Breed'n Betsy®) than for those who only had theoretical training. Furthermore simulator training resulted in a more realistic student assessment of performance, as well as in a better understanding of where reproductive structures were located (cervix, uterus) in live animals. No significant difference in effect of training was found between the different simulators used here. The results of this study suggest that it is in the interest, not only of students but also of the animals, that simulator training occurs before exercises are performed on living animals.","PeriodicalId":8761,"journal":{"name":"Berliner und Munchener tierarztliche Wochenschrift","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34612105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most prevalent serovar was lcterohaemorrhagiae (11.1%), followed by serovar Bratislava (9.6 %) and Grippotyphosa (1.9%). Mares showed a significantly higher occurrence of antibodies (p < 0.05) than geldings or stallions. Horses used for breeding have a significantly lower risk than horses used in sport or horses used for leisure activity. There was also a significantly higher prevalence (p < 0.05) in summer than in the other seasons. No significant influence of breed, husbandry conditions and age on the antibody occurrence was observed (p > 0.05). The clinical chemical parameters did not differ significantly between horses with positive or negative Leptospira antibody result (p > 0.05). It became apparent that horses can be infected with Leptospira without developing of clinical symptoms.","PeriodicalId":8761,"journal":{"name":"Berliner und Munchener tierarztliche Wochenschrift","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34612104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case-control study on cattle health investigated the possible association between a multifactorial event and the occurrence of unspecific productivity losses. 35 dairy farms were defined as cases and 65 farms as controls, when they met two out of three eligibility criteria, respectively (cell count, mortality and life production of cows). Case farms had relevantly more often problems with forage collection (too low cutting height), feed storage (no foil used), and energy supply of dairy cattle (insufficient feeding of corn silage and lowered energy content of grass silage). Case farms had relevantly more often dirty lying areas, feeding and walking alleys, feed bunks and watering places as well as more cows with dirty udders, flanks and legs than control farms. Farm individual self-control as well as veterinarian and agricultural consultancy should focus on these management areas. Furthermore, the health situation should be checked regularly on an individual animal level for diseases of the locomotor (especially by intensifying claw care), metabolic and reproductive systems. Additionally, 22 so-called intermediate farms with considerable herd health problem during the study period were investigated for possible exogenous influences on the farm performance. There were no indications for influences by the soil type, weather conditions at harvesting or wild bird occurrence on cropland, which might be as well due to the explorative nature of the study. However, herd health problems were apparent in case and intermediate farms more often and more diversely than in control farms.","PeriodicalId":8761,"journal":{"name":"Berliner und Munchener tierarztliche Wochenschrift","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34475034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two case-control studies were carried out using production data from 1996 to 2012 to analyse the impact of BVD virus (BVDV) on fertility in dairy herds in the province of Styria during an eradication programme. In study 1, herds in which at least one persistently BVDV-infected (PI) animal was detected (case herds) were compared to a group of control herds proven free from BVDV infection (contro herds). In study 2, within BVD infected herds the period during which P animals were present (exposed period) was compared to the period after successful BVD eradication (unexposed period). Calving interval (CAl) and the probability of a first service conception (FSC) were used as indicators in a mixed regression model to investigate the impact of BVD on reproductive performance. The model results indicated that BVD had a significant influence on CAl and FSC. Cows from control herds were 1.1 times more likely to conceive at first service compared to cows from case herds and cows served during the BVDV unexposed period were 1.3 times more likely to conceive at first service than those inseminated during the exposed period. In BVD-infected herds the CAI averaged seven days shorter in unexposed periods than in exposed periods. Besides BVD the animal breed and the parity substantially impact the analysed fertility indicators.","PeriodicalId":8761,"journal":{"name":"Berliner und Munchener tierarztliche Wochenschrift","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34475032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
