A contrasting beef production week. 27 month old steers were slaughtered off a forage only diet as part of my trial work. They never received any concetrates in their lifetime. In contrast at home bulls were brought to the factory at 16 months finished off ad-lib concentrates.

We have an exciting new research technician post available as part of the RumenVentory project supported by DAFM and DAERA. This job will entail collecting methane emissions from beef cattle at pasture. Job details attached topjobs-teagasc.thehirelab.com/LiveJobs/JobAp… @TeagascBeef @TeagascGrass10

Some tips from Peter Doyle, Teagasc Grange around the Management of Red Clover #BeefCon24

The impact of clover on suckler beef cattle performance will be discussed next week at the @TeagascBeef conference. These heifers were finished off grass-clover swards with no meal at finishing. Carcass weight 308kg, R=, 3=, 19 months of age. @TeagascGrass10 @teagasc

@MjScallan I haven’t personally seen or heard any myself this year, but of course it can be an issue this time of the year.

@PeterDoyle_1 @TeagascGrass10 @TeagascBeef Quick question, Peter. Is anyone else having trouble this year with too much clover in the swart causing bloat. Huge issue here with wealings 🤬🤬🤬🤬

3rd cut of red clover in the Derrypatrick herd in Teagasc Grange Variety: Fearga Sown 2.5 years ago This particular field contains 90% clover @TeagascGrass10 @TeagascBeef

@Walsh50Brendan Just from my experience, I have always seen the grass content return to at least 75 % content the following spring. We had 7kg/acre of grass in our mix.

@PeterDoyle_1 @TeagascGrass10 @TeagascBeef Have you any experience of the grass content dropping in a red clover silage sward? In our 2021 & 2022 set paddocks the grass content fell off after yr1 but the red clover is stronger than ever and doesn’t look to be going anywhere at the moment

@Walsh50Brendan @TeagascGrass10 @TeagascBeef The clover content changes throughout the year, it was 15% for 1st cut, 50% for 2nd cut and typically 80- 90% for 3rd cut. So for a red clover silage field I would expect that content. I would not graze the field at that 90% content.

@PeterDoyle_1 @TeagascGrass10 @TeagascBeef Has the grass content fallen off or was that clover content always the intention Peter?

In Grange this Wednesday, at the @teagasc #BEEF2024 Open Day, @teagasc and @ucdagfood Walsh Scholar Peter Bennett will be in the Grassland & Forage Village discussing the effect of including white clover in the grazing sward on beef cattle performance @TeagascGrass10

There are a number of great PhD opportunities available in Teagasc Grange (see comments). One of these includes a PhD on Evaluating lifetime enteric methane emissions from the suckler beef herd, see link: teagasc.ie/media/website/… @TeagascBeef @teagasc @agriculture_ie @ucdagfood

🥁🥁📢Funded PhD to work on reducing N loss in integrated cropping and livestock systems with Plantain as a NBS📢 come study in a joint programme between ⁦@teagasc⁩ and ⁦@ucdagfood⁩ closes April 5th ⬇️

Excellent PhD opportunity available to work on the @agriculture_ie funded Beef-Quest project focused on reducing the finishing age of Irish beef cattle. This PhD will encompass a mixture of on farm data collection, animal production trials and farm systems modelling (1/2)

Researcher, @PeterDoyle_1 on the @teagascbeef Derrypatrick suckler beef herd shows how two calves will live a Grass only or a Grass-Clover grazing life from now on☘️🌱

Calving kicked off in the Derrypatrick herd this week with this Whitecliffe Orwell heifer calf weighing 48kg at birth Orwell €170 on terminal, 5.5% calving difficulty on mature cows, not suitable for heifers at 12.2% CD. Calved no problem, up and sucking Only 82 more to go!

For the final episode of 2023, @TeagascBeef Researcher Peter Doyle is on this week’s episode of #TheBeefEdge to give a review of the Derrypatrick herd in Teagasc Grange in the past year. Listen in bit.ly/43x3M8m

It was great to get a brief insight into beef research in Australia. Despite getting 900mm of rain on farm the lack of seasonality is obvious! A key similarity to home is the urgent requirement to focus research on enteric methane emissions and incorporating legumes into pastures

Researchers from Teagasc Grange Research Centre report on the effect of forage or concentrate beef production systems on farm profit, carbon footprint, land use and meat nutritional value. bit.ly/43I6453

Got an oppurtunity to visit suckler beef farms in Indiana, America. • Grass-based systems • Different grazing management (see pictures) • Alot of Angus genetics • Strongest breeding focus is calving ease and marbling • Alot of zero nitrogen systems and dependence on clover

Ireland was very well represented today at the Livestock Production Systems session of the @IGC2023 in Kentucky @ucdagfood @TeagascBeef @teagasc
