OviCast

Sheep specialist, Michael Gottstein, joins this week’s OviCast to outline the key priorities for the month ahead.We discuss the challenges around fertiliser use and rising costs, why replacing fertiliser with concentrates can be a false economy, and how simple management changes like grouping ewes and subdividing paddocks can boost grass growth. We also cover key flock health risks, including parasites, lameness and grass tetany, before finishing up with practical tips on preparing for high-quality silage.For more episodes from the OviCast podcast, visit the show page at:https://www.teagasc.ie/animals/sheep/ovicast-sheep-podcast

Dr. Orla Keane joins us to discuss coccidiosis in lambs, a common but often underestimated issue affecting flock performance. We cover what causes coccidiosis, its impact on lamb health and growth, and the key symptoms farmers should watch for. With the challenging spring weather conditions, we also look at why the risk of infection may be higher this year and what that means for on-farm management. We finish with a practical discussion on treatment and prevention, including how different coccidiostats, their active ingredients, and dosing strategies work to control the disease.

With lambing season well underway, we catch up with Dr. Nóirín McHugh to discuss how to identify and select the best ewe lambs as future replacements, and what genetics we are introducing into the flock.Nóirín explains how genetics influences a wide range of production and behavioural traits — from litter size and lambing ease to mothering ability and lamb vigour — as well as their role in reducing undesirable issues such as prolapse and lameness.We also explore how observations made during lambing can be used to make more informed replacement decisions, helping to drive long-term flock performance. Finally, Nóirín outlines what to watch for as the season progresses, ensuring that selection decisions made now continue to deliver benefits throughout the yearFor more episodes from the OviCast podcast, visit the show page at:https://www.teagasc.ie/animals/sheep/ovicast-sheep-podcast

For this special joint podcast on bluetongue with Catherine Egan from the Beef Edge and Stuart Childs from the Dairy Edge, we’re joined by vet John Donlon to get an insight into bluetongue. Primarily transmitted via biting midges, the cases on farms in Northern Ireland significantly reinforces the need for awareness on farms in the Republic of Ireland. Early action, identification and isolation will be key in reducing the potential for further virus spread. Temperature is a major factor in the transmission of bluetongue. The typical transmission period usually runs from late spring to early autumn, especially during the summer months. During the winter, the risk of disease spread is much lower. Bluetongue is associated with many symptoms. Typically, in affected cattle and sheep, the main symptoms may include: fever and loss of appetite; drop in milk yield (dairy cows); reddening of mucous membranes; sores on the nose, gums or dental pads; swelling of the face, lips or tongue (‘blue tongue’); breathing difficulties, drooling or nasal/eye discharge; lameness due to inflammation at the top of the hoof; abortion or foetal deformities; and, in severe cases, infection can result in death. For further info: Teagasc urges vigilance on bluetongue - Teagasc | Agriculture and Food Development Authority Bluetongue is a notifiable disease, meaning anyone who suspects an animal may have the disease is legally obliged to notify DAFM without delay. To report a suspected case of Bluetongue virus to the Department of Agriculture, Food and the Marine (DAFM), you should immediately contact your local Regional Veterinary Office (RVO) or the National Disease Emergency Hotline. Contact details:· During office hours (9 am - 5 pm): Contact your local Regional Veterinary Office (RVO)· Outside office hours (operational 365 days a year): Ring the National Disease Emergency Hotline at 01 492 8026 For more episodes from the OviCast podcast, visit the show page at:https://www.teagasc.ie/animals/sheep/ovicast-sheep-podcast

Sheep Specialist, Damian Costello, joins us to discuss practical approaches to reducing labour demands during the winter housing and lambing period. Damian outlines key husbandry practices that can help minimise interventions with ewes later in the season, highlighting how early planning can pay dividends when workload is at its peak. We also explore the importance of shed layout, pen design and ventilation in creating an efficient working environment. The discussion covers a range of potential investments, from simple, low-cost improvements to more significant upgrades, all aimed at making day-to-day tasks easier and reducing pressure during this time of year.
