Beyond the Bale : September 2019
ON FARM 45 additionally split into the two ewe types used in the trial. Macquarie’s field day was hosted by the Macquarie Sire Evaluation Association and NSW DPI at the Trangie Agricultural Research Centre (TARC). Macquarie Sire Evaluation Association site chairman David Greig outlined the background to the ewe base. “The base ewes for the site were sourced from the commercial clients of two bloodlines. One ewe base was sourced from large framed, heavy cutting Merino flocks that averaged between 20.5 and 21.5μm, whilst the other was sourced from all purpose Merino flocks which averaged between 18.0 and 18.5μm.” “The ewes from these two bloodlines were equally allocated to each sire,” David explained. Chris Bowman, the professional classer, at the Macquarie site commented during the pen-side sire introductions that some sires had clicked better with one type of ewe compared to the other. “There were a couple of very productive skin type sires that clearly showed how important it is to consider the ewe type when you are making joining decisions,” Chris said. “The progeny from the heavier skin type sires over the plainer, longer stapled ewe type produced a much better result, and vice versa. Stud masters, in general, understand this when considering skin type (productive supple skins vs plainer, flatter skins) when making joining decisions.” NEW ENGLAND – TRENDS AND CHANGES TO CLASSER’S GRADE The New England’s June MLP field day hosted by the New England Merino Sire BREEDERS FLOCK, SIRE NUMBER PROGENY NO TOPS (%) CULLS (%) YA2TA2 Connemara Poll, 140257 51 -11 -7 114 Conrayn, MVB123 48 5-3 -12 0 Cressbrook, 140055 44 2 01 7 Egelabra, HEK 1.36 49 -7318-1 Grindon, 150017 47 -14 -20 13 33 Karori, 140188 54 5-8111 Miramoona, 140012 40 2516-20-8 Mirani, 120021 59 -9 -12 2 1 Moorundie Poll, NE73 29 1024-1 -6 Nerstane, 150073 41 211-11 -8 Petali Poll, 150697 48 4-3 -14 -15 Trefusis, 150282 57 0182-7 Trigger Vale Poll, 140477 42 -13-15-15 West Plains Poll, 110004 (Mercenary) 49 0-41 -4 Yalgoo, 150313 53 -12-1 -2 AVERAGE 47 17192322 Table 1: New England 2017 Drop Classer’s Visual Grade Results – June 2019 Table 1 is an excerpt from the New England MLP Field Day Report showing the Classer’s Visual Grade results at the Yearling (Y) and Adult2 (A2) stage for the 2017 drop F1 ewe progeny.

MLP project F1 ewes returning to the paddock in dry conditions following the New England field day, June 2019. Evaluation Association and CSIRO, was run in conjunction with the MerinoLink conference. Both the 2018 and 2017 drop ewes were on display in an extensive penning of 30 progeny sire groups. The field day featured the second year of classing results for the 2017 drop. The Classer’s Visual Grade results in Table 1 below shows some sires of the 2017 drop achieving a consistently good classing performance across both years, whilst others have had dramatic improvements from their yearling (Y) to adult (A2) classing. Jock McLaren, MLP sire entrant and AMSEA Chairman, attended both the New England and Macquarie field days. “The presentation of the ewes at the Macquarie and New England sites was a credit to the site hosts, NSW DPI and CSIRO, particularly in these ongoing tough drought conditions. Thanks must go to AWI which has made additional contributions to the feeding costs at all three drought-affected MLP sites,” Jock said. “I was also really encouraged to see so many young faces at the field days,” added Jock. “We had a group of students from Farrer Memorial Agricultural High School at the New England field day. They spent time with Angus Carter from Landmark who is one of the classers involved with the site and with Ben Swain from AMSEA learning about the results. That’s a great feature of sire evaluation and the MLP project – these days provide a good balance of information along with a chance to network and ask questions.” MORE INFORMATION www.wool.com/MLP FUTURE MLP FIELD DAYS Western Australian Merino enthusiasts are invited to attend a MLP field day at UWA’s Ridgefield Farm, Pingelly on 25 October.
