AFBI Hillsborough recently hosted over 70 dairy farmer co-researchers for a special event on calf rearing.

The aim of the event was to provide an update from recent research investigating the quality of colostrum and management strategies across different farms as well as providing management advice for calf health, housing and hygiene.
Liquid Gold
Colostrum is the essential first feed for the newborn calf, containing the nutritional properties required for growth and antibodies needed to establish immunity and reduce the risk of calf ill health and mortality. However as shown by the AFBI colostrum project, not all colostrum is equal with there being large variation in terms of nutritional quality and bacterial contamination. Furthermore, in a recent AFBI survey of 66 dairy farms across Northern Ireland, only 13.6% of farmers routinely tested colostrum which puts calves at risk of failure to establish passive immunity. Dr Gillian Scoley (AFBI Hillsborough) reminded attendees at the ‘Calf event’ that providing 3-4 litres of good quality colostrum (which should provide more than 50g IgG/L) within the first few hours of life can have a positive impact on calf growth, health and future milk production.
Plan to Prevent
Calves face many disease and management challenges in the first year of life, which, if handled incorrectly, can impact on future health and productivity. Aurelie Moralis (BVA NI Branch President) highlighted that balancing and managing the risks of disease are essential for successful prevention. Attendees were also reminded that vaccines are an aid to control disease rather than a cure and that failure to store and administer them correctly can result in ineffective cover. A key message was to always speak to your vet if you are unsure about how to handle, store or administer vaccines!
It’s all about the hygiene!
Calf performance is driven by the management of nutrition, health and the environment in which the calf is reared. As part of the current DAERA funded Optihouse calf housing project, AFBI alongside the CAFRE Dairy Advisory team recently completed calf housing and rearing system assessments on 66 dairy farms across Northern Ireland.
Detailed information on management practices, animal health and performance and the physical characteristics of the rearing house including ventilation and hygiene assessments were recorded. As expected a large variation in housing design, management and calf and house performance was observed.
The message to producers from Aaron Brown (AFBI Hillsborough) and Jamie Robertson (Livestock Management Systems) was that development of standard hygiene protocols for both rearing facilities and equipment is vital to lower the risk of disease spread in the calf house. The next phase of the project aims to develop custom ‘fixes’ for existing calf houses to help improve hygiene and ventilation within the rearing environment.

Dr Aimee Craig (AFBI Hillsborough) indicated that the risk assessment app is currently being piloted through several local veterinary practices with the aim of large scale release.
Things to remember!
Investing the time in designing and delivering an effective newborn calf management protocol within a rearing environment designed to meet the needs of the calf will help maximise the lifetime performance of your dairy heifers!
