Donal Patton and Barry Reilly join Emma-Louise Coffey on this week’s Dairy Edge podcast to identify the optimum stocking rate based on feed supply and the profile of annual grass growth. Barry explains that the long term average grass production at Ballyhaise is 14 tonne DM/ha. Donal outlines the profile of growth: magic day of ~40 kg DM/day achieved in late April while grass growth of ~80 kg DM/day. This growth represents a challenge in the balance of grass supply, a deficit of grass grown during the shoulders of the year and surplus during the mid-season. An optimum overall stocking rate of 2.3 LU/ha and a milking platform stocking rate of 3.0 cows/ha was identified for the Ballyhaise dairy herd based on consistent 14 tonnes DM/ha. Barry explains that cows get out to grass for 270 days in the year but when taking into account the number of cows calved during the spring and cows housed during inclement weather, cow grazing days are 235 days. Donal quantifies the level of supplement required by cows above grazed grass: 700-800 kg concentrate and 1,400 kg silage, half of which is required during lactation.

Donal Patton and Barry Reilly joined Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss building robust milk production systems in the border, midlands and western region. Barry outlined current annual performance from the Ballyhaise herd: 470 kg MS at 4.62% fat and 3.65% protein, 80-83% average 6 week calving rate and 361 day calving interval. Donal explained that the current research involves establishing white clover into grazing swards in an effort to reduce the chemical Nitrogen required to support grass productivity. Donal says that this will examine the issue of persistence of clover in heavy clay drumlin soils. Barry acknowledged that the strategy of front loading clover establishment at Ballyhaise is not realistic at farm level. It involved a full reseed on 25% and oversown clover on 15% of the milking platform. Feeding levels of 600 kg or 1,200 kg are being fed per cow to compare lower reliance on feed input to the standard feeding rate in the region. The economic and environmental impact of higher feed levels will be examined across 4 lactations.

Olin Greenan joins Emma-Louise Coffey for the second part of his interview on this week’s Dairy Edge podcast to give further insights into his production system. Olin first explains what his lactation looks like: calving from early July to mid-September, mating starts in early October with dry off at the end of April. However, he explains that the 2021/22 lactation proved challenging owing to a prolonged dry spell during the summer hitting in New Zealand at Christmas. Previously the summer drought lasted for 6 weeks but Olin says that this has increased to 10 weeks in recent years which has prompted him to revisit his feeding strategy. To counteract drought conditions, he reduces milking frequency to OAD or 3 in 2 as well as supplementing in order to preserve body condition and support milk production into late lactation.

Irishman Olin Greenan joins Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss how his dairy farming career has developed in New Zealand. Olin recalls the decision to travel to New Zealand for one year after he finished his degree in agriculture and how that developed into a twenty-year farming career from farm assistant to farm manager, contract milker and now 50:50 share milker. Olin explains that early on in New Zealand he was struck by the clear progression pathway for someone interested in dairy farming and the access to finance required to own your own cows. He also outlines the challenges he has faced including periods of low milk pay out and managing people. During low milk pay out, business growth was stagnant. When managing people, he says, there is a balance in creating a good working relationship but also providing a clear boundary and line of command on the farm.

This week’s Dairy Edge celebrates the evolution of the Kildalton dairy herd over the last 50 years with contributions from past and present staff at the college. James Ryan and Zerlina Pratt as well as John Connolly and Norman Storey join Emma-Louise Coffey with their insights and memories. In fifty years, the dairy herd has grown from 40 pedigree British Friesian cows producing ~3,500 litres of milk at 3.5% fat and 3.0% protein (260 kg MS) in 1971 to 120 high EBI Holstein-Friesian and crossbred cows in 2021 producing 530 kg MS. The dairy herd has also contended with animal health challenges such as depopulation due to two Brucellosis in the 1970s and Mycoplasma Bovis in 20% of the herd in the 2000s. The dairy herd aims to achieve high productivity per cow and per ha through sustainable farming practices while also facilitating skills training for agriculture students who attend the college to help put theory into practice.

Johnstown Castle farm manager, Aidan Lawless, joins Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss the performance of the Winter Milk Herd. Aidan quantifies the production performance of the winter milk herd at 630 kg MS from 7,000 litres, which is driven by a right calving season of 10 weeks, high EBI genetics and high quality base winter forage in the form of grass silage. Aidan explains that MS have increased by approximately 10 kg year on year owing predominantly to improved genetics as grassland management and fertility performance is relatively consistent. In relation to winter feed, the winter milk cow is generally fed 1/3 grass silage, 1/3 maize and 1/3 concentrates. Grass silage quality is fundamental to maintaining high performance at moderate concentrate input and preventing stomach upset in cows such as acidosis. To achieve 74-75 DMD silage, Aidan explains they need to cut silage in mid-May.

Dairy advisor, John McNamara, and Shinagh dairy manager, Kevin Ahern, join Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss the system of pushing milk solids per hectare from grazed grass and low levels of supplementary feeds. John explains that since cows started milking on farm in 2012, the focus has been on converting grazed grass to milk solids with a low reliance on purchased feed. Over the last number of years, milk solids has been 420-440 kg milk solids per cow from less than 500 kg concentrate and milk solids per ha of 1,100 kg. Kevin suggests small tweaks such as the addition of more clover to grazing swards as well as being more selective with culling poorer yielding cows can lift milk solids per cow. John explains that chemical Nitrogen has reduced from the traditional 250 kg to 178 kg in 2021, and a target of 150 kg in 2022. Kevin quantifies what this looks like practically: all paddocks get 60 kg N by April and subsequently, paddocks with >15% clover will get 8-9 kg Nitrogen and paddocks with >20% clover no further Nitrogen is spread. Both John and Kevin explain their cautious approach to reducing chemical Nitrogen as grass needs Nitrogen to grow and, unless clover content is sufficient, Nitrogen application is essential.

For this week’s podcast version of the Let’s Talk Dairy webinar series, Stuart Childs, Teagasc Dairy Specialist, does some checks and balances in relation to breeding. Stuart discusses the need to run a weekly fertility report to track progress and identify the cows not yet bred. It is also important to make sure that you AI for long enough before releasing bulls and use high DBI bulls to generate high quality beef.

Lameness experts, Ger Cusack and Ned Dunphy, join Emma-Louise Coffey on this week’s episode of the Dairy Edge podcast to discuss the level of lameness that exists in grazing dairy cows and the proactive steps that farmers can take to reduce its incidence. Based on a recent on-farm study, up to 20% of cows within Irish dairy herds have some level of lameness and Ger explains that cows suffering from lameness are coping with pain which is a significant welfare concern. Ger recommends that cows with lameness are treated with an anti-inflammatory to combat pain, reduce swelling and promote healing. Ned explains that simple practices on farms such as allowing cows to walk at their own pace when droving from the paddock to the parlour for milkings, as well as a regular footbathing programme, looking after the surfaces of roadways and learning the skills to identify a lame cow and lift and treat cows, will go a long way towards minimising the level of lameness. Ned estimates that each incidence of lameness costs €350 owing to loss in production, reduced fertility performance, the cost of treatment and culling. Furthermore when considering farm sustainability, Ger explains that cows are culled because of lameness, they fail to reach maturity and this compromises cow lifetime productivity.

Micheál O’Leary from PastureBase Ireland joins Emma-Louise Coffey on the latest Dairy Edge podcast with advice on how to keep control of the grass on your farm, maintain quality and avoid feed waste as growth rates explode across the country. Currently, average farm cover is 790 kg DM/ha / 203 kg/cow, growth 70 kg/day, demand 56 kg/day and almost half of dairy farms have a pre-grazing cover of >1,600 kg DM/ha. Micheál recommends that dairy farmers take action to reduce the pre-grazing cover to 1,300-1,400 kg to hit paddocks at the 3-leaf stage to ensure good digestibility and quality to support high milk solids production. Where surplus grass is taken out in the form of bales, Micheál reminds us to replenish key nutrients (Phosphorus and Potassium) using 2,500 gallons of slurry where available on farm or alternatively, a compound such as 18-6-12.

On this week’s episode of The Dairy Edge, advisor Adrian O’Callaghan and dairy farmer Diarmuid Hegarty join Emma-Louise Coffey to consider the potential feed saving that can be achieved by identifying problem cows and culling them from the herd early. Diarmuid explains he is milking 200 cows and running an overall milking platform stocking rate of 2.5 cows/ha that rises to 4-4.5 cows/ha across the mid-season. He had intended on keeping 10-20 extra cows in 2022 but gained discipline to calve and cull the additional cows because of forecasted high costs of production. Adrian details that costs of production were estimated at €1,840 in January but indications now expect they could rise to €2,400. Of 730 dairy farms that completed the Profit Monitor last year, Adrian said 25-30% are buying in the equivalent of 2 bales/cow or ½ tonne DM. He speculates that for some farms that means a portion of cows are fed totally from bought in supplement. If you identify 5 problem cows in the herd and cull them now, there is a potential saving of 125 tonne fresh weight of feed (two-fold difference: removing cows grass/silage demand and additional area for silage). Diarmuid is sticking to his normal silage conservation plan to ensure he has adequate winter feed reserves. He has however gotten his slurry tested and is spreading slurry and chemical fertiliser to complement the soil fertility status.

Agri-economist, Trevor Donnellan, joins Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss the dramatic rise in production costs and speculates whether strong milk price can maintain profit margins. Prior to the war in Ukraine, milk price was set to decline from early 2022. Following the outbreak of war, milk price has continued to rise and outlook remains high until at least Q3 of 2022. High milk price being received by Irish dairy farms is driven by strong dairy product pricing as well as lower than anticipated milk supply in the southern hemisphere and logistical and processing capacity issues from additional milk in the US. From a cost of production standpoint, fertiliser price remains high at up to €1,000 per tonne while projected concentrate feed is expected to run 20% ahead of 2021 prices. Energy costs in the form of green diesel and electricity are projected to run to 60% and 30%, respectively, ahead of 2021. Trevor explains that dairy farmers are well placed to maintain strong profit margins despite rising costs due to the high milk price being received in 2022.

Dairy Farmer, Tom O’Connell, joins Emma-Louise Coffey on this week’s episode of The Dairy Edge podcast to give an insight into the key drivers for a successful breeding season on his farm. Tom operates a spring calving, grass based system, milking 320 crossbred cows who produce in excess of 500 kg MS from 800 kg meal. Tom explains that the high level of milk production is achieved due to a long lactation resulting from a 90% 6-week calving rate and a mature herd. Notable breeding metrics for Tom’s farm include: 90% 3-week submission rate, 60% conception rate to 1st service and 4% empty following 11 weeks breeding. Tom places importance ensuring cows are in adequate BSC ahead of mating start date and having defined calving and breeding seasons so all cows are calved prior to mating start date. Additionally, Tom explains that he puts energy into heat observation to ensure all cows that are in heat are picked up and served.

Frank Buckley joins Emma-Louise Coffey on this week’s episode of The Dairy Edge podcast to discuss the role of cross-breeding and the use of alternative dairy breeds in Irish milk production systems. Frank outlines the fundamentals of cross-breeding, including: removing the risk of in-breeding, introducing breed complementarity and exploiting heterosis. Frank explains that in-breeding is not a major concern in Ireland but there are gains in dairy cow performance in the form of complementarity and heterosis when mating two genetically diverse breeds. Frank says that various breeds have been evaluated in Irish seasonal production systems including Montbeliarde, Normande, Norwegian Red and Jersey. The use of Jersey genetics has dominated in comparison with other alternative breeds owing to the compatibility of the Jersey crosses to a grass based system, early maturing breed, good fertility and efficiency at converting grass to milk. Norwegian Red has been used to a lesser extent, but farmers favour this breed for the animal health benefits it confers. Conversely, Mountbeliarde and Normande crosses were less popular given that they are a late maturing breed which impacts on ability to achieve compact calving season, heifer’s ability to calve down at 2 years and cow’s ability to go back in calf. Frank recommends that farmers select the best genetics available for their farm system, regardless of breed. For a spring calving, grass based system, dairy farmers need a moderate sized cow with good fertility to ensure she calves timely each year and has the ability to produce high milk solids from predominantly grazed grass.

Dairy farmer, Jim White, and grassland researcher, Mike Egan, join Emma-Louise Coffey on this week’s episode of The Dairy Edge podcast to discuss the establishment and management of white clover through over-sowing. Mike recommends that dairy farmers make a plan to establish white clover for the grazing platform and can target up to 25% of the platform with a combination of a full reseed with perennial ryegrass + white clover and over-sowing white clover in existing grass swards. Jim established 16% (11 of 67 ha) of his milking platform with white clover through over-sowing in 2021. He explains that key to the success of establishment was grassland management, measuring the milking platform every 5 days during the peak grazing season and grazing at a cover of 1,100-1,200 kg DM/ha. Mike explains that there are 3 components that determine the success of over-sowing: nutrients (adequate soil fertiliser pre-sow), moisture (for up to 6 weeks post-sow) and light (to assist germination, establishment and persistence at the base of the sward).

For this week’s podcast version of the Let’s Talk Dairy webinar series, Stuart Childs, Teagasc Dairy Specialist, discusses when to start the second round of grazing in 2022. Firstly, Stuart outlines how the start time varies from year to year. You need to look back to go forward - to see what's on the first grazed paddocks – and where that is going to dictate the start of the second round. You also need to re-assess weekly due to the ever changing weather.

Dairy Specialist George Ramsbottom joins Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss best practice for management of heifers in order for them to calf down timely in seasonal calving systems. Firstly, George explains that only 80% of dairy heifers calf, owing to heifers not achieving target weight prior to mating start date, sub-optimal breeding management and mortality. At mating start date, heifers should weigh 60% of their mature live weight and this is dictated by genetics; individual heifers’ live weight can be calculated based on their maintenance sub-index. For heifers identified as below target, George recommends that they are separated from the main group and fed high quality grass, where weight gain in excess of 1 kg per day can be achieved. George encourages farmers to select ‘low risk’ calving difficulty sires for heifers to ensure ease of calving in heifers next spring.

Tillage specialist, Mark Plunkett, joins Emma-Louise Coffey on this week’s Dairy Edge podcast with advice on fertiliser strategies for silage ground, taking into account uncertainty around supply and the soaring cost of fertiliser. Mark explains that the recommended fertiliser application is 100 kg Nitrogen, 20 kg Phosphorus, 125 kg Potassium (35 kg of which after first cut) and 20 kg Sulphur to support a 5 tonne DM/ha yield. Furthermore, he acknowledges that the recommendation was previously 125 kg N, but given the cost and availability of fertiliser, this has reduced. The first 80 kg N will support 75% of the silage crop, the next 20 kg N will support the 20% of the crop so in order to achieve adequate first cut with winter feed reserves in mind and farmers should aim to spread 100 kg/ha. Mark encourages farmers to maximise the use of slurry on silage ground as 3,000 gallons of slurry/acre makes up the majority of P and K requirements as well as up to 30 kg N.

Dairy advisor, Bernadette Bennett, joins Emma-Louise Coffey on this week’s episode of The Dairy Edge podcast with advice for farmers on how to make the best breeding decisions so as to maximise the genetic gain of their herd. Firstly, Bernadette gives insight into an analysis she completed on 100 dairy clients: the top 20% had an average EBI of €186 and produced 498 kg MS while the bottom 20% had an average EBI of €121 and produced €451 kg MS. Bernadette explains that the difference in MS produced equates to €282 per cow (assuming 1kg MS = €6) or in excess of €39,000 for the average herd of 139 cows. Bernadette encourages farmers to use the Female Selector on HerdPlus to select cows that are suitable for dairy AI and identify cows with lameness, high SCC, poor temperament, sub-optimal fertility or low milk production for beef AI or culling. When selecting a team of bulls, Bernadette reminds us of the importance of the bull team, with a maximum of 15% of cows served to one sire. Bernadette also identifies traits for profit including improving milk solids and to achieve 9% solids (5% fat and 4% protein), the bull team needs fat PD of 0.28 and protein PD of 0.18.

Dairy farmer, Mike Bermingham, joins Emma-Louise Coffey on this week’s Dairy Edge podcast with an update on the grazing and calving season during February, and looks forward to the remainder of the first grazing rotation. On 1st March, Mike had 32% of the farm grazed and an average farm cover of 1,000 kg /ha. Mike intends on maintaining a high level of grazed grass in the diet in March, supplementing with 4 kg meal and high quality baled silage if farm cover dips below target. Mike had a significant issue with milk fever 2 years ago, explaining cows were over-conditioned, silage was high quality and he has crossbred cows who are predisposed to milk fever. Mike has taken proactive steps to reduce cases including BCS at dry off, mineral analysis on silage, restricting silage intake and feeding straw once per week.

Padraig explains that there are several reasons: cows have been dried for a significant amount of time and therefore an early milk recording will establish the baseline SCC for the herd and identify any problem cows. Furthermore, it is an opportunity to assess the success of the dry period. Padraig recommends that farmers consider the role of persistently high SCC cows, particularly if they are older cows with multiple records of high SCC in previous lactations. He explains that these cows will likely continue to elevate bulk SCC and are at risk of spreading mastitis infection to low SCC cows in the herd.

Emma Behan from Progressive Genetics joins Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss the process of milk recording, differentiating between DIY and manual milk recording events. Emma quantifies the rise of milk recording by 23% in the Progressive Genetic geographic area, given the greater emphasis on selective use of antibiotics at dry off. She explains that the last two weeks of March is the busiest time for milk recording and farmers should consider recording in early March in order to get maximum value from the results. Emma acknowledges that farmers generally wait until all cows have calved to complete the first recording, but says that farmers should instead go when 60-70% of cows are calved, with all subsequent calvers picked up later in the year, in the second or third recording.

‘The Moovet’ Eamon O’Connell joins EmmaLouise Coffey on this week’s Dairy Edge podcast with his insights into the common ailments he has seen on dairy farms since the onset of calving. Eamon explains that the main call outs in early February are to assist calving and treatment of milk fever. He recommends that farmers allow cows time for birth to progress naturally - two hours from when the bubble appears. Eamon also comments on the increasing level of milk fever in early lactations and explains the reasons for this may include the level of magnesium may not be sufficient in the dry cow diet, the demand for calcium in high volume cows at the onset of lactation and cows’ inability to mobilise calcium from their skeleton. He recommends that farmers take proactive measures to minimise milk fever because it is a gateway disease to other ailments such as ketosis, displaced abomasum, retained cleanings and high SCC/mastitis.

Teagasc is running a weekly Let's Talk Dairy webinar series which is also being made available as a bonus podcast episode. For this week’s webinar, Stuart Childs, Teagasc Dairy Specialist, discusses the plan for Spring grazing in 2022. Stuart outlines what is important to watch out for and some actions that people can be taking. It is important to have a Spring Rotation Plan (SPR), as well as a Spring budget. Regular farm walks will help you make the best decisions in relation to grass supply on your farm. Good Spring grazing underpins excellent cow performance both in early lactation and mid-season.

Dairy advisor, Grainne Hurley, joins Emma-Louise Coffey on this week’s episode of The Dairy Edge to provide tips on balancing the competing objectives of feeding the freshly calved cow and hitting grazing targets during the first grazing rotation. Grainne recommends that all farmers complete a farm walk to quantify how much grass is available on farm right now. Based on farms she works with, average farm cover is 1,033 kg DM/ha (range 712-1,205). Knowing how much grass you have will inform how much area you can graze per day. Grainne explains that cows have a low intake after calving, eating approx. 11 kg dry matter/day, increasing by 0.5-1 kg per day until peak intake is reached at week 7 of lactation. Grainne quantifies the quality of spring grass (1.03 UFL, 21% crude protein) v 70 DMD silage (0.8 UFL, 13% crude protein) and given the superior feed quality, she recommends that farmers maximise the amount of grazed grass in the diet in early lactation.

Teagasc is running a weekly Let's Talk Dairy webinar series which is also being made available as a bonus podcast episode. For this week’s webinar, Stuart Childs, Teagasc Dairy Specialist, discusses when you should spread chemical Nitrogen - specifically Urea - this Spring. It is important to have a plan in place and to have your soils analysed. Early N application should also have more grass on the farm in the run into the start of the second rotation.

Dairy Specialist, Martina Gormley, joins Emma-Louise Coffey on this week’s episode of the Dairy Edge to assess the factors that impact on the length of the working day on Irish dairy farms. Martina analysed milk recording results which provided AM and PM milking start times and she explains that milking interval dictates PM milking start time with a 71% of variation in the length of the working day. The ideal milking interval is 16:8, meaning 8 hours between morning and evening, while in reality, the milk interval is on average 10 hours, ranging from 7 to 16 hours. Martin also discusses how Irish dairy farms rely on hired labour to complete the farm workload, are competing with other industries, and therefore, working conditions, such as a work finish time, are important to attract and retain labour.

On this week’s episode of The Dairy Edge, Dairy Specialist Patrick Gowing joins Emma-Louise Coffey with an insight into projected costs of production in 2022 and strategies to maintain profitability. Patrick explains that costs of production are expected to be in excess of €1,500, increasing from €1,311 in 2020, with fertiliser and concentrate accounting for 40% of total costs. Patrick recommends that dairy farmers calculate break-even milk production to cover costs; the formula= total cost of production / milk price (per kg milk solids). For mature cows with milk solids below the break-even production are a cost to the system.

Given the significant rise in fertiliser prices, Signpost programme advisor Seamus Kearney joins Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss how to minimise the requirement for chemical N in the first round through strategic use of slurry. Seamus quantifies the quantity of Nitrogen in slurry at approximately 23 units per 2,500 gallons using Low Emission Slurry Spreading equipment and he recommends that farmers target 50% of the farm with slurry during the first round (Jan and Feb) when the weather forecast and ground conditions are favourable. For the other ½ of the platform, Seamus recommends that farmers should have 23 units of Nitrogen ordered and ready in the yard for application from mid-Feb. Seamus compares protected Urea and CAN fertiliser products per kg of Nitrogen with protected Urea at €950 per tonne costing €2.06 per kg N while CAN at €700 per tonne costs €2.59 per kg N. Seamus explains that protected Urea is the recommended Nitrogen product of choice; research at Teagasc Johnstown Castle has shown that the use of protected Urea has shown an increase in grass production whilst reducing Nitrous Oxide emissions.

Dairy specialist, James Dunne, joins Emma-Louise Coffey on this week’s Dairy Edge podcast to discuss the key learnings from the recent Once-a-Day milking conference. He discussed Dr Emer Kennedy’s report on the OAD experiment at Teagasc where cows were compared on full-time OAD, full-time TAD and short-term OAD. For cows on OAD for the first 4 weeks of lactation, daily milk solids were 20% lower while full lactation milk solids were 10 kg lower compared to TAD cows. On average, OAD milking reduces total daily milking time by 30%. Meanwhile, Don Crowley explained that 60% of incidence of high SCC or mastitis originate during the dry period. Don encourages farmers to take action now to minimise risks, that cows are in correct BCS, cows are fed adequate dry cow minerals, cubicles are clean and dry and the milking parlour is serviced before the start of lactation. James also explained the concept of ‘10 in 7’ (10 in 14 milkings), a new milking frequency farmers are using on farm to reduce labour input. In practice, cows are milked TAD on Monday, Wednesday and Friday with milking times of 7 am and 4 pm and OAD on Tuesday, Thursday, Saturday and Sunday with milking time of 10 am.
