Performing regular mobility scoring is recommended on farms to monitor the prevalence of herd lameness and identify (and subsequently treat) lame cows promptly, but mobility scoring can be subjective and may be difficult to regularly implement on farm. Accordingly, there is increasing interest in the automation of lameness detection with direct and indirect methods described.

The results identified areas to optimise calf health and welfare, with a particular focus on extended colostrum feeding (beyond the first 24 hours of life). Chi squared analysis, Cochran Armitage trend tests and logistic regression were used to investigate biologically plausible associations between variables. Thematic analysis was used to construct and refine thematic maps. There was a significant linear trend between the frequency of blood sampling of calves to monitor serum IgG concentrations and testing of colostrum for IgG concentration (P<0.01). A number of farms (41.53%) pooled colostrum (without pasteurising), which may reduce overall IgG concentration and increase disease transmission risk. Timing of colostrum harvest (within 6 hours of calving) was suboptimal on some (23.39%) farms. Many of the perceived barriers to extended colostrum feeding were human and physical, including tangible commodities such as storage and facilities, labour and procedural issues.","PeriodicalId":100879,"journal":{"name":"Livestock","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135800344","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}

With some batching options, it may be possible to move expertise between different farms within a company. The combined benefits boost the wellbeing and welfare of the pigs and farm staff.

Many diagnostics tests are available for small ruminants, and the difficulty is to know which are the most appropriate for the disease/condition in questions, taking into consideration economic factors, the performance of the test(s) and the sampling methodology.

The consequences of suboptimal supply can result in various clinical presentations. However, in some instances, unproven trace element deficiencies and their correction have been lauded as a panacea for all manner of conditions. Therefore, it is important to gather sufficient evidence to support a presumptive diagnosis and justify laboratory test expenditure. These tests are often not as diagnostically definitive as we would like and should be interpreted in conjunction with background evidence. In addition, a better understanding of the factors contributing to each particular presentation of deficiency may improve targeted nutritional management.","PeriodicalId":100879,"journal":{"name":"Livestock","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78995676","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}

There are limited scientific data to support such claims and much of what little evidence there is emanates from North America and South Africa, so it would be useful if the observations and experiences of UK adoptees could be backed up with some well-controlled field studies. In their absence, considerations of some aspects of known parasite biology, such as the larval ecology of parasitic nematodes, can shed light on likely outcomes of various types of pasture, grazing and animal management. Minimising the use of anthelmintics in regenerative systems requires effective monitoring to ensure that animal performance and health do not suffer as a result of parasitism; for youngstock, growth rate is the most reliable marker for subclinical parasitic gastroenteritis. Consideration should also be given to other parasites that can affect grazing livestock, such as lungworm, fluke, ticks and flies, in order to determine the influence of regenerative management on the parasite fauna and their collective impact on sheep and cattle.","PeriodicalId":100879,"journal":{"name":"Livestock","volume":"110 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87695487","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}
