Fifty calves with diarrhoea from the nine intensive dairy farms were assessed during the study period. Of these, 72% (n =36) were positive for E. coli There was a strong link between the prevalence of E. coli in calf diarrhoea and the age groups. Therefore, those under the age of one month were 1.3 more likely to be infected with E. coli than those between one and three months of age. The Antibiogram test revealed that E. coli isolated was highly responsive to the antibiotics tetracycline, chloramphenicol, sulfamethoxazole, streptomycin and doxycycline, but less susceptible to the drugs amoxicillin, ceftazidime, nitrofurantoin, and kanamycin and resistant to the antibiotics cefotaxime and vancomycin. Results from interviews and regular observations in the study area indicate that young calves were more impacted by diarrhoea, which accounted for about half of all health issues in calves. The E. coli recovery rate was significantly higher in calves that were one week old. These findings supported the hypothesis that the level of calf diarrhoea was excessive and would be detrimental to dairy output.","PeriodicalId":15030,"journal":{"name":"Journal of Applied Animal Research","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45681524","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 overall seroprevalence of bovine and human brucellosis was 0.61% (95%CI:0.016–2.09) and 1.21% (95%CI:0.032–4.27) respectively using combined RBPT and CFT tests.

However, with the ever-increasing population growth, the free-range or backyard poultry farming system is no longer adapted to supply people with protein requirements. Crossbreeding local hens with an improved rooster weakens the thermotolerance and disease resistance of the offspring in African areas. In this context, the available breeds need to be preserved. The improvement of their productivity should be actualized through the implementation of a sustainable production programme that is simple and less expensive for the farmer, taking into account: feeding, habitat and chicken care. Scientific research should invest more time on the identification and characterization of all available breeds or chicken ecotypes allowing us to know production performances and their nutritional needs. Feeding with locally available resources, vaccination and use of indigenous medicine requiring training of farmers are essential perspectives. This paper focused on the productivity and resilience of indigenous chicken ecotypes in various African tropical environments and some essential factors to improve the birds. For this, a critical analysis was made based on the available data on the birds from research databases.","PeriodicalId":15030,"journal":{"name":"Journal of Applied Animal Research","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48758333","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}

No dairy farm could be found without positive samples for D. nodosus and the majority of the farms were free or had very low prevalence of F. necrophorum (0–9.1%). Statistical difference for the prevalence of D. nodosus and F. necrophorum in different Slovak regions was detected for both strains. Logistic regression revealed an association between both D. nodosus and F. necrophorum identification and annual milk production (odds ratios = 0.69 and 0.32, respectively).
