Sean Coughlan, CEO of ICBF, joins Stuart Childs on this week’s Dairy Edge podcast to discuss the origins of ICBF, what it has done since its creation back in 1998 and what the future looks like for dairy breeding. Sean first gives a brief description of how ICBF came into being under the stewardship of Dr. Brian Wickham as the first CEO in 1998 when it was formed. He then explains the creases that had to be ironed out when ICBF started highlighting the variation in calving dates that existed initially due to the multiple layers at the time and how over time with the cooperation of all stakeholders, this has become a thing of the past with much more streamlined data flows ensuring accurate recording with no duplication. This has allowed ICBF to create the database that is the engine of dairy and beef breeding in Ireland. The links with the genetics and modelling departments of Teagasc have allowed ICBF to develop EBI initially, DBI and CBV more recently as well as suckler beef indexes all of which are created to drive genetic gain and ultimately profitability for Irish farmers. Sean says that the power of genetics is enormous and that while the improvement is often perceived to be slow, it works and that the potential of new technology such as the genotyping scheme to further improve genetic gain is very real and a huge opportunity for the Irish dairy and beef breeding industry.

New entrant dairy farmer, Liam Brophy, joins Emma-Louise Coffey on the latest Dairy Edge podcast to discuss the conversion process of his family farm as well as successes and challenges along the way. Towards the end of Liam’s school years, milk quota abolition offered the opportunity to milk dairy cows on his home farm. Following extensive discussion with his father Mark, Liam set about completing the Dairy Herd Management course at Gurteen College and the Dairy Farm Management course at Kildalton College and Moorepark to gain the relevant knowledge and hands-on experience to prepare himself for the process of converting the home farm from drystock to dairy. Prior to milking, investments included purchasing heifers, building a parlour, installing a water system and paddocks. The most recent building included a cubicle shed which replaced straw bed housing. Reflecting on the last 5 years, Liam explained that while they had planning approval to build the parlour almost a year prior to start milking in February 2020, the unanticipated impact of Covid-19 delayed the build of the milking parlour which forced them to milk in a temporary parlour for almost the full year. This delay presented the greatest challenge in the early days. The Brophy family, now in their 4th season milking, have 142 high EBI black and white cows calving in 2024. In 2023, the cows produced 500 kg MS at 4.5% fat and 3.7% protein.

On this week’s Grass10 grazing management update, Joseph Dunphy discusses the latest PastureBase data, Dry Matter % and Predicted grass growth, rainfall & soil temperatures for the week. Jospeh explains how an adjustment of your first grazing rotation will need to be made depending on your % grazed during February. He also has a grazing update from featured farmer, Joe Murphy from Co Kilkenny, and he discusses the importance of sulphur this spring. Link to this week’s newsletter: https://bit.ly/Grass10-5thMarch
As a joint episode between The Dairy Edge and The Beef Edge podcasts, dairy farmer, Paul Delaney, and Teagasc beef specialist, Catherine Egan, join Emma-Louise Coffey to discuss the importance of genetics in dairy-beef systems to maximise performance and profitability. In 2024, Paul plans to use sexed semen on the top 35-40% of his herd followed by continental beef straws. When considering the impact of calving continental breeds, Paul says he focuses on calving difficulty and gestation length and has not encountered issues at calving. He compares his experience of calving suckler and dairy cows and explains that he finds the dairy cows ‘open up better’ to calf and they are fit rather than fat, given the difference in their body condition at calving. Paul has two repeat customers since he began milking six years ago, one for his Friesian bulls and one for his continentals. He sets the price for the calves based on the market value in the given year. His priority is to sell a healthy, good quality calf that will provide a margin for the beef farmer. For farmers who are placing a greater focus on the dairy beef index this year, Paul encourages farmers to give it a go and try with a handful of their cows. Where it works well, it will give farmers the confidence to continue adding value to the dairy beef calves into the future.

Joseph also has a grazing update from featured farmer, Fergal Coughlan from Co. Cork, who has managed to graze 25% of his farm so far this spring. He discusses tips to get cows to grass and how to structure your daily workload so cows get out for a 2nd allocation of grass in the afternoon. He also discusses the PastureBase grazing calculator & early chemical Nitrogen. Link to this week’s Grass10 newsletter: https://bit.ly/Grass10-20thFeb
‘Vet on the Moove’ Hazell Mullins joins Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss the priorities to achieve high herd health status and gives her tips to limit disease outbreaks this spring. Hazell identifies use of farm data, diagnostic testing and hygienic facilities as target areas to promote herd health and prevent disease outbreak. In relation to an effective vaccination programme, Hazell recommends that individual farmers assess their farm situation, whether there is movement of stock to out farms, contract reared where potentially in contact with other stock or disease markers are rising in diagnostics testing. As the busy calving season progresses, Hazell explains that despite farmers best efforts, illness outbreak typically occurs when the infection pressure exceeds the immunity of animals, especially the young calves.

Don Crowley, Teagasc Milk Quality Specialist, joins Stuart Childs on this week’s episode of the Dairy Edge to talk about how to take control of SCC in the early stages of lactation. Don first outlines the importance of a fresh cow group to manage the transition to the main milking group which is a key step to set cows up for the year ahead. This fresh cow group will allow added attention to be given to both cubicles and the cows themselves in terms of preparation and observation of milking. Don also advocates using the Californian Milk Test (CMT) on all cows immediately prior to allowing their milk into the bulk tank. This step will allow for early identification of sub clinical mastitis and facilitates appropriate early intervention to control the infection. This process will cost time at what is a busy time of year already but it is time well worth investing and will set your cows up for their full lactation.

On this week’s episode of The Dairy Edge, dairy advisor Kay O’Connell joins Emma-Louise Coffey to address priority tasks from supporting cow and calf health to setting up the farm for the grazing season of 2024. Kay recommends that farmers complete a spring rotation planner as a means of increasing the proportion of grazed grass in the dairy cow diet. Kay explains that grazed grass is highly digestible and high in protein and will support milk production and body condition in early lactation. Kay discusses the considerations for Once-A-Day milking in early lactation. She explains that the biggest benefit comes from the labour savings. Addressing concerns about reduction in milk yield, Kay quantifies that during the 4 weeks OAD milking in early lactation, yield reduces by 22-24% but cows bounce back and there is no difference in overall production. In terms of calf care, Kay emphasises the importance of the 1-2-3 of colostrum and hygiene in feeding implements and calf beds.

Mike Egan joins Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss the balance between achieving optimum dairy cow intakes and good graze outs in early lactation. Mike first considers the dynamics that dictate dairy cow intake in early lactation including parity, quality of the dry cow diet, cow liveweight, health and EBI. He explains that recent research estimates that the average cow in the herd will eat approximately 13 kg DM following calving, which is higher than the previous research which was carried out in the late 2000s. However, Mike points out that despite the initial greater intake potential at week 1 of lactation, the weekly rise in the appetite of the cow is less than previous estimates (0.8 kg per week rather than 1.0 kg). Peak intake of 17-18 kg is reached at week 10 of lactation. Mike says that in mid-January, farm cover was sitting at 830 kg DM/ha across farms that have measured and recorded grass on PastureBase and therefore there is great scope for grazed grass to make up the majority of the dairy cow diet in February. Mike recommends that each farmer gets out to measure grass cover to assess exactly how much grass is available to them and to prepare a Spring Rotation Planner and Feed Budget for the months ahead. This will ensure cows are fed with the best quality feeds possible to support milk production and body condition and supplement is fed at appropriate rates and spec where necessary.

Pat Tuohy and William Burchill join Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss how farmers can maximise the value of slurry through tactical use and having optimum storage facilities on farm. At the outset, William says, if you are not prepared to go with bagged fertiliser, you should not be willing to slurry. In order for this to play out on farm, William explains that farmers need sufficient storage to allow flexibility in their system, particularly in late January and February. William quantifies the value of slurry at €40/1,000 gallons with a nutrient profile of 9 units of Nitrogen, 5 units of Phosphorus and 32 units of Potassium. William explains that 80% of the value of slurry comes from the P & K components and how farmers need to be tactical about where they spread (paddocks with low P & K or silage ground), how (LESS technology) and how much (using the appropriate rate). William acknowledges the variation in nutrient value of slurry, be it covered or uncovered tanks or the type of stock feeding into the tank, and recommends farmers consider slurry sampling to know the exact profile of the slurry product. Patrick has put an estimate of capital investment in slurry storage for typical options farmers choose from slatted tank, €790 per cow (€450/foot), to over ground tank, €835 per cow, and slurry bag, €325 per cow. In an ongoing study across 100 dairy farms in Ireland, Pat recognises the contribution of rainwater whether to uncovered storage facilities and runoff not being channelled away from tanks. This can put existing facilities under significant pressure throughout the closed period.

Marion Beecher joins Emma-Louise Coffey on this week’s episode of The Dairy Edge to discuss a recent case study of farmers who achieve an average 8 hour working day on their dairy farm throughout the year. Marion explains that in the study, farmers cited a compact, seasonal calving system as the key driver of their labour efficiency and recognised that the average 8 hour day ranged with longer working days during calving and breeding to much shorter days when cows are dried off Marion identified some top practices that lend themselves to lower labour demands including a good milking parlour with less than 8 rows going through the parlour (farm facilities), group calving pens (work practices), automatic calf feeders, collars (technologies) and setting an evening finish time (work organisation). Ahead of the spring calving season on dairy farms, Marion encourages farmers to get a good break and well deserved rest, prepare as much as possible by having facilities set up and the relevant supplies to hand on farm and to ensure there is sufficient help available for the calving.

William Burchill, FBD Lecturer in Soil Science in UCC, is on this week’s Dairy Edge podcast discussing Nitrogen Use Efficiency (NUE) from a wholefarm point of view but also from the point of nitrogen applied. William explains how wholefarm Nitrogen Use Efficiency works and then how NUE can be used in terms of the fertilisers (organic or chemical) applied to land. William discusses the 4 Rs of fertiliser application: Right type, Right place, Right timing and Right rate. William also outlines a fertiliser shopping list for farms which will include protected urea as the main source of nitrogen and the requirements for P and K being addressed through 16% Super P and Muriate of Potash (0:0:50) or compounds such as 18:6:12 or 0:7:30. The response to sulphur (S) also needs to be considered for fertiliser applications with recent work showing up to 25% increase in grass growth where S is included. Finally, William recommends people test their soil, test their slurry, build a nutrient management plan and follow it ensuring to use the allowances that are available to the farm due to the importance of keeping all nutrients at the appropriate index in order to drive grassland performance.

International dairy consultant, David Beca, joins Emma-Louise Coffey for part two of his discussion on the Dairy Edge podcast to discuss the global milk supply trends over the last two decades and he speculates what milk producing nations have the capacity to meet growing consumer demands. David explains that demand for dairy is growing by 1-3% per annum with the range being determined by economic conditions. Examining individual countries, David sees compounding growth in milk supply in countries such as Ireland, New Zealand and South Africa while others have remained static or contracted e.g. the UK and Australia. David anticipates that the Irish dairy industry has the capacity for continued growth in supply in the future but clarifies that this is dependent on external regulation and individual farmers’ ability to have clarity in their production system and utilisation of grass in the diet.

International dairy consultant, David Beca, joins Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss the fundamentals of cost control in grazing systems. David discusses pasture harvest, as defined as grass utilised on the milk platform, and consequently, the proportion of pasture in the dairy cow diet, as the key driver of low cost, high profit grazing systems. Furthermore, David compares the relative costs of feedstuffs in Ireland and international competitors. He explains that the relative cost of grazed grass and supplement is much greater than in countries such as USA owing to the ability of Irish farms to grow grass so cheaply. He costs grass at $60 v concentrates at $400, reinforcing the impact of imported feed on the cost structures For more information go to: https://www.teagasc.ie/media/website/events/2023/David-Beca---Key-drivers-of-milk-production-costs-in-dairy-systems.pdf For more episodes from the Dairy Edge podcast go to the show page at: https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com https://www.lastcastmedia.com
Cathal Buckley, Researcher at the Rural Economy Unit in Teagasc Athenry, joins Stuart Childs on this week’s Dairy Edge podcast to discuss the results from the sustainability report of 2022 that was published in October of this year. Cathal first outlines the number of dairy farms involved in the survey and some of the figures associated with them such as the average dairy cow number of 92. Cathal discusses the reasons for the reduction in the per hectare emissions on dairy farms in 2022. The main reason being the reduction in chemical fertiliser applied but also due to the change in the fertiliser type with the switch from CAN to straight urea and protected urea. However, he explains, due to the switch to straight urea over protected urea, there was an increase in ammonia emissions. The change to urea based fertiliser has been a positive but it needs to change to protected urea to have maximum impact on ammonia. Cathal says that efficiency gains have been good but have been eroded by the increase in the national herd so we need to continue to adopt the technologies to drive down the overall emissions and then the greenshoots of research in relation to methane emissions from rumination can potentially have a significant impact when they do eventually come to the market. Cathal finishes by recommending that farmers look to rapidly embrace clover and multispecies which are looking promising in their early research to reduce the reliance on chemical fertiliser which is subject to fluctuation due to the ongoing geo-political climate.

Teagasc’s Richie O’Brien and Joe Patton join Emma-Louise Coffey on the latest Dairy Edge podcast to reflect on the progress made after a decade of expansion whilst also discussing concerns in areas such as the economic consequences of overstocking the milking platform. Richie explains that the advice now is similar to pre-quota: efficiency before scale, getting the simple things right like soil fertility, producing more grass, completing a financial plan to dictate decisions at farm level. When considering the rise in milk production, Joe explains that for the most part it has been beneficial from an economic and social perspective. Joe urges farmers to look specifically at their farm’s feed situation. What proportion of the dairy cow diet is coming from grazed grass and how much external feed is being imported onto the platform, be it through concentrate or purchased forage? There was consensus among Joe and Richie that farmers should budget 5.5 tonnes of grass utilised and 800kg concentrate per cow, meaning a farm stocked at 2.5 cows per ha needs to grow 15 tonnes of grass.

Dairy advisor, Jim Moyles, joins Emma-Louise Coffey on this week’s Dairy Edge to discuss the financial performance of dairy farms in 2023 and potential areas where farmers can focus on to protect profits. Jim documents farm accounts for 27 farms from January to September and he explains that farm receipts have declined by €800 per cow compared with 2022 resulting from a 15 cent/litre drop in milk price while production remained steady to the end of August. Farm costs remained relatively steady with variable costs increasing by €8 and fixed costs increasing by €60 year-on-year. Consequently, surplus cash has declined from €1,550 per cow in 2022 to €700 in 2023. Jim reminds us that this surplus cash must cover own labour/drawings, tax and repayments. Jim advises that all farmers should complete a cost control planner in order to assess their individual farm situation because a group average masks a lot. While the average surplus cash is €700 per cow, the range across the group was -€17 to +€1,300. Characteristics of the farms achieving higher surplus cash include good milk and animal sales and a tight control on costs.

Pablo Silva Bolona, mastitis researcher at Teagasc Moorepark, is on this week’s Dairy Edge podcast to discuss his research and recommendations into successfully implementing selective dry cow therapy (SDCT) on farms for the drying off season in 2023. Pablo first explains the concept of selective dry cow therapy saying the main risk periods for cows are the two weeks after dry off and the 2 weeks before calving as well as early lactation due to the stress of calving reducing immunity to disease. Individual cow records will be necessary for vets to prescribe correctly so people should milk record as close to drying off as possible as the research conducted on commercial farms by Pablo and his team have shown that the SCC in the final recording is strongly linked to identifying cows that require antibiotic treatment. For those that have not milk recorded yet this year, they should look to start recording before the end of lactation and continue to record in 2024. Alternatively, although a far more laborious way, is to take quarter samples from all cows and get these analysed. Pablo finishes by highlighting that nutritional management of yield is important, with cows dried at <15kg of milk per day having better treatment outcomes under SDCT. The cleanliness and stocking density of cubicles are also an important factor with twice daily cleaning and liming of cubicles contributing to better outcomes. A surprisingly high level of infection in 1st lactation animals resulted in a higher threshold or cut point for 1st calvers from the predictive model developed from the research. This was 100,000 for the 1st lactation cows and 65,000 SCC for the 2nd lactation plus cows. This is not to say that farmers should only apply SDCT to cows at these thresholds as many farmers are successfully using higher thresholds with great success with some farmers successfully using sealer only treatment on 80-90% of their herds. Seeking advice and making informed decisions on what cows to treat or not and excellent hygiene at post drying and in the run into calving can see SDCT implemented on Irish farms with little or no impact on the SCC of the herds or nationally.
