The productivity and financial gain from dairy cross-breeding Apr 11, 2022

Show notes

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.

The establishment and management of white clover through over-sowing Apr 04, 2022

Show notes

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).

Let's Talk Dairy Bonus Episode: When to start the second round in 2022 Apr 01, 2022

Show notes

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.

Best practice for management of heifers in seasonal calving systems Mar 28, 2022

Show notes

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.

Fertiliser strategies for silage ground with current supply and cost issues Mar 21, 2022

Show notes

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.

Let's Talk Dairy Bonus Episode: Synchronisation Protocols for 2022 Breeding Season Mar 18, 2022

Show notes

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, was joined by Dr Stephen Moore, Teagasc to discuss synchronisation protocols for the 2022 breeding season. Given the current climate it is going to be important to try and retain as many cows as possible in the herd. Stephen gives an overview of the various options around synchronisation for heifers and cows - sexed and conventional semen protocols.

How to make the best breeding decisions to maximise the genetic gain of your herd Mar 14, 2022

Show notes

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, on his February grazing & calving season and advice for the remainder of the first rotation Mar 07, 2022

Show notes

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.
