This chapter outlines the steps required to detect reproductive problems and limitations in cows and herds. It then elaborates some strategies to overcome limits to reproductive health and production concentrating on detecting cows requiring attention through record monitoring, analysing herd records to monitor reproduction and identify areas that limit performance and providing strategies to deal with these limits. The main limits addressed are anoestrus and inadequate oestrus detection that are addressed through education of farm workers, aids to oestrus detection and the use of planned breeding programs to induce and control oestrus and breeding. Nutritional causes of limited reproductive performance are also considered as well as strategies to limit abortion.","PeriodicalId":114555,"journal":{"name":"Improving dairy herd health Improving","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133975124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chapter begins by reviewing the importance of lameness then goes on to discuss claw horn disruption. It also reviews aetiopathogensis of white line bruising and lesions, which is then followed by a section on aetiopathogensis and control of digital dermatitis. A case study on an 800 cow Holstein herd with a sudden rise in sole ulcers and white line lesions is also included. The chapter concludes with an overview of the emerging diseases in dairy cattle.","PeriodicalId":114555,"journal":{"name":"Improving dairy herd health Improving","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130499137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
