Following on from last week’s OviCast, Michael Gottstein joins Ciarán Lynch on the latest episode to discuss planning a fertiliser budget for your farm this year. Michael starts by discussing the challenge that increased fertiliser prices pose on farms and why it’s important to take action now. He explains why it’s important to look at your overall fertiliser spend on farm now and take into account what merchant credit and alternative credit is available to avoid the situation of unforeseen debt later in the year. Michael outlines a practical example of a fertiliser budget that he completed for a farmer this spring. He details how the farmer will incur an increase in spend but, through product substitution and a slight reduction in application rate, it will still allow the farmer to spread 80% of the nitrogen he used last year with the budget available. Michael discusses the option for some farms to reduce stocking rate by selling unproductive stock and why it’s a year to focus on the basics of grassland management and correcting soil pH. Finally, Michael encourages farmers to complete a fertiliser budget and seek assistance from advisors in completing this task where necessary.

Grassland researcher, Dr Philip Creighton, joins Ciarán Lynch on this week’s OviCast podcast to discuss various aspects of grassland management this spring. Philip starts by discussing current grass availability on farm with the higher than average winter growth. He moves on to the topic of fertiliser purchases this spring and Philip emphasises the need to complete a budget for the fertiliser spend on the farm this year. Philip explains the impact that timing, conditions and grass covers have on response rates for fertiliser this spring and he also discusses tailoring fertiliser application rates depending on stocking rate and demand on farm. With producers considering alternative feed supplies, Philip highlights the pitfalls of relying on purchased concentrate to make up the shortfall in feed supply where fertiliser isn’t applied. Philip also discusses using available slurry and FYM and why compound P & K will need to be applied on recent reseeds, where clover has been established, and low indexed silage ground where needed. He encourages farmers to consider conducting a soil test this year and to apply lime where needed. Finally, Philip highlights how getting grazing groups established early will be key to managing supply this spring with reduced fertiliser input – a topic OviCast will revisit as spring progresses.

On this week’s OviCast, Ciarán Lynch heads to Westport in Co. Mayo where he was joined by Tom Gill and Teagasc Advisor John Noonan to find out more about Ólas Hill Farms. Centred around Westport, Ólas Hill Farms was initially set up with a focus on breeding sales which then expanded to encompass a producer group that now has more than 400 members. Tom is a member and one of the co-ordinators of the group and he explains how it has delivered for his own system and that of the other members. The group works closely with Kildare Chilling where they send more than 30,000 lambs annually. With stock all produced locally and with transport leaving Westport three times a week, they discuss the type of lamb being sent, with Tom explaining how the group co-ordinates this, acknowledging the efforts of the committee and staff within the group. The breeding sales are still very much a part of Ólas Hill Farms and John and Tom explain more about this. John also discusses how the group has worked with the various stakeholders to develop a dedicated website where customers can find out more about their story and how the lamb was produced and the Ólas Hill Farms brand that they hope will be on the shelves in European markets.

Head of sheep in Teagasc Michael Gottstein joins Ciarán Lynch on this week’s OviCast podcast to discuss the control of external parasites in sheep. Michael starts by describing how plunge dipping was common practice on many farms and now needs to be considered once again for external parasite control particularly to replace the use of injectable macrocyclic lactones (Group 3-ML) products for whole flock treatment. They discuss best practice when it comes to dipping with Michael emphasising how the duration the sheep are dipped for has a big impact on its efficacy. He highlights the need to replenish the dip concentration as the active is removed during the dipping process and explains the option of using mobile plunge dipping providers or considering incorporating it into a handling unit. He also discusses dip disposal and why it’s vital this is done in a safe manner before finishing up encouraging farmers to consider dipping as a control option for external parasites.

When new animals arrive on farm they can potentially bring some unwanted health issues with them. To minimise the risk, it’s important there is a quarantine procedure in place and on this week’s OviCast, Michael Gottstein, Head of Sheep in Teagasc joins Ciarán Lynch to discuss this issue in more detail. Michael starts by emphasising why this is an important consideration for any flock owner. He discusses the importance of inspecting the sheep at purchase and asking some basic questions of the seller about the health status of their flock. Some preparation is needed to correctly quarantine animals on arrival and Michael highlights the need to house these animals for 48 hours and correctly treat them for foot issues, internal and external parasites and Michael and Ciarán discuss the treatment options that are currently available. They move on to discuss turnout post treatment and why it’s a good idea to keep these animals separate from the main flocks for a number of weeks after purchase. Finally, Michael highlights the need to enrol these sheep in the flock’s health plan for the farm ensuring they receive the appropriate vaccinations.
