This workshop will explain in detail the latest standards included in the Red Tractor Dairy Assurance Scheme herd health section, including the requirements of a herd health plan and the veterinary review. There will be discussion and demonstration of the interpretation of the standards, the requirements of veterinary involvement. The use of the myhealthyherd herd management programme will be demonstrated live, and the new access for farmer members will be shown, allowing farmers to create Red Tractor compliant herd health plans that their veterinary surgeons can monitor and manage, including standard procedures for the treatment of common conditions, and the use of vaccines. There will be an interactive session using the software to allow delegates to review health records and create priorities and action points in compliance with the Red Tractor Standards, using real farm examples. Easy methods of collecting and collating the necessary records will be demonstrated. The learning outcomes will be that veterinary delegates will fully understand their obligations under the new Red Tractor Dairy Standards, will be able to not only help their clients create a compliant herd health plan, review the health outcomes and sign of their review, and also make the process a useful part of herd health planning, using the opportunity to get more involved in pro-active herd health management.

The new Red Tractor Standards for dairy farms include the requirement for farmers to record culls, the main reasons for culling and to diferentiate involuntary culls from voluntary culls. Various data sources show that about 24% of culled dairy cows leave the farm dead and with no value, either as deaths or casualties that required slaughter on farm (Orpin and Sibley 2014). The prevalence of sick, deaths and casualties is very variable between farms indicating that the problem is not inevitable. Perinatal deaths due to injury, recumbency and acute illness are the most common and costly reasons. This workshop paper will demonstrate easy methods of recording and analysing culling rates and the primary reasons for culling as well as differentiating early lactation culls, deaths and casualties, from late lactation voluntary culls. From this, and economic evaluation can be calculated to justify interventions that will prevent and control involuntary culling. Practical ways of identifying high risk cows in high risk places will be discussed, and real farm examples will be used to highlight risks and how they can be controlled practically and effectively to minimise the severe losses that some farms tolerate, and yet are often unrecognised by the veterinary surgeon.

The economic losses due to culling within dairy herds vary considerably from herd to herd which may appear to have the same overall culling rate. An increasing proportion of emergency culls and culls with no value within a herd will markedly impact on the overall culling costs. There is a wide variation in the rate of emergency culling and culling of animals with no value between herds, which clearly demonstrates that these types of culls are not inevitable and there is an opportunity to reduce the incidence and subsequent economic losses if effective management systems can be applied. Conducting a structured economic audit of culling using tools to audit culling rates and costs (www. myhealthyherd.com) as part of a health planning process can highlight avoidable losses and illustrate the profit opportunities for the farmer, and the focus for veterinary intervention. The risk of emergency culling is not evenly distributed within the farm. Certain high-risk cows (freshly calved, lame, high body condition score at calving, in oestrus) are more at risk from culling if they are combined with high-risk areas (for example, slippery concrete, inadequate feed and water space, congestion points). Proactive management of the herd to reduce the number of high risk cows which are exposed to high risk areas of the farm is a useful and often ignored route to reduce the risk of emergency culls and culled animals of no value thus improving farm profits and cow welfare.

Johne's disease is a debilitating and economically important disease for dairy and beef herds. Many herds are al-ready infected, for example 40-70% of dairy herds. More are at risk so herds need to be protected from infection as well as controlling Johne's where it exists. Practical and effective control programmes can be tailored to any farm and regional control schemes are developing with collaborations between farmers, vets, and other organizations. The key is for all involved to understand the disease and engage in a common objective whilst adopting a system that will work for their specific circumstances. Source

The objective was to examine (a) how pregnancy rate on one farm (500 cows) was affected by signs of oestrus and disease stressors and (b) whether pregnancy rate could be maximised by considering cow activity. The signs of oestrus and timings were recorded at artificial insemination (AI), and cow activity was monitored by neck collars. Pregnancy rate tended to be higher in animals that displayed standing oestrus (35 v 26 per cent; P=0.06) but was 10 per cent lower in those cows with an elevated somatic cell count (SCC; >200,000 cells/ml milk) within 0-4 or 4-8 weeks prior to AI (P=0.01 and 0.05, respectively), irrespective of the incidence of clinical mastitis prior to AI. Cow activity data were available for 525 inseminations (from a total of 1299). The mean interval from increased activity to AI in all cows (11 hours 32 minutes; 95 per cent CI 10 hours 40 minutes to 12 hours 24 minutes) was not different for cows that did or did not establish a pregnancy (P=0.90). The pregnancy rate improved to the average of unaffected cows if AI was delayed by about eight hours in animals with an elevated SCC 0-4 weeks prior to AI (P=0.025), indicating that, in cows with prior elevated SCC, AI could be repeated approximately eight hours later to achieve maximum pregnancy rates. © 2015, British Veterinary Association.
