The Dairy Edge

Ricki Fitzgerald, Farm Manager of the Teagasc Moorepark Kilworth Farm, and Brian McCarthy, Researcher in Teagasc Moorepark, join Stuart Childs with a run down on how the year has gone so far on the Kilworth Farm and to talk a little about the Next Gen 2 trial that is in its first full year in 2026.
 
Ricki says they had quite a good spring in 2026 despite the weather challenges with minimal health issues. Regular body condition scoring and managing cow condition was a significant part of this success. 
 
Grazing, while challenging, happened almost every day during the spring but only because they had the cover to start with and excellent infrastructure on the farm. A batt latch bought a few years ago has been instrumental in facilitating grazing in the evening during the spring also. 
 
The farm started breeding on April 27th and so far results have been exceptionally positive, with 96% of cows submitted in the first three weeks and early pregnancy scanning showing very high conception rates.
 
Brian then spoke about the previous next generation trial and the outcomes of it and the the rationale for the current trial Next Gen 2 which is comparing National Average Holstein-Friesians with Elite Holstein-Friesians and Elite Jersey-cross cows. 
 
The previous iteration of the trial  (2013–2016) showed that high-EBI cows were more fertile, survived longer in the herd, produced higher-value milk solids, and generated approximately €275 more profit per cow annually thus validating the EBI. 
 
Early results from the set-up year of 2025 and the figures from 2026 so far indicate that elite genetics continue to deliver higher fat and protein percentages, increasing milk value compared with national-average cows. 
 
However, this trial goes further than the effect of the genotypes as it is also looking at sustainability and beef performance through evaluating different stocking-rate systems, nitrogen-use efficiency, methane emissions, and overall environmental performance as well as examining how dairy cow genetics and beef sire selection affect dairy-beef calf value and lifetime beef performance.

For this week’s Grass10 grazing management update, John Maher explains that June is a challenging month for grass quality as we are now in the main heading phase for perennial ryegrass.
 
Pre grazing yield is too high on many farms:
-       Watch rotation length (Target 18-21 days)
-       Minimise stem content
-       Grazing covers >1500 kg DM/ha will have a negative effect on animal performance, pasture cleanout, grass recovery and quality in the subsequent rotation

With breeding season reaching the midpoint on many spring-calving dairy farms, we're taking stock of how the season has progressed so far and discussing the key management decisions for the weeks ahead.
 
Doreen Corridan, CEO of NCBC, joins James Dunne to discuss breeding performance to date, trends in dairy and beef semen usage, managing cows that have yet to be served, and the key actions farmers should focus on for the remainder of the breeding season.

For this week’s Grass10 grazing management update, John Maher discusses tackling surplus grass and why flexibility is required to take out surplus bales.
 
Plus he explains how grazed grass delivers the lowest feed cost, even with higher fertiliser prices.
 
Meanwhile, the featured farmer is John Payne from Moydow, Co. Longford.

With the increased cost of fuel and fertiliser, Peter Doyle, Grassland Researcher in Teagasc, Grange, joins Stuart Childs to discuss the cost of growing grass, silage and other feeds.
 
Peter outlines the costs that he uses in the Grange Feed Costing Model which are of course assumptions but are necessary for the model to function.
 
He emphasises that grazed grass delivers the lowest feed cost, even with higher fertilser prices. The cost model estimates grazed grass at about 14c/kg dry matter (including land charge), compared with roughly 42c/kg dry matter for concentrates.
 
Feed quality is important in the model as the energy of the feed influences the performance it delivers. Peter argues that delaying first-cut silage to chase higher yields given increased fuel costs to get better bang for the buck from contractor costs is a false economy. 
 
Earlier cutting (around late May) produces higher-quality silage, improves the total energy yield of the overall two-cut system as well as supporting better animal performance, reducing the requirement for expensive concentrate supplementation. Big first cuts of low quality material don’t deliver more silage and are ‘penny wise, pound poor’ due to the cost they create subsequently.
 
Peter also stresses that feed quality should be matched to the type of stock being fed. High-quality silage is needed for lactating cows and young stock, while lower-quality, higher-volume silage may suit dry cows. 
 
He notes that alternatives such as maize and fodder beet can be useful but involve similar or higher costs, additional management requirements, and often require supplementary protein and minerals.
 
Finally, Peter says that the cost of grazed grass doesn’t increase as significantly as the other feeds and thus people need to focus on grazed grass as their primary feed source and maximise the amount of it that they produce and consume to minimise their overall feed costs.
