To our valid clients,
As you may remember here at Rene Stud we were conducting a trial using maiden merino ewes joined to Charollais Rams, due to their growing popularity especially with maiden ewes we thought we would see for ourselves how they would perform.
Our aim was to lamb maiden ewes out unassisted & take the lambs through to kill weight, and then finally see how they kill out at the abattoir & assess our results.
We have tagged the lambs with electronic tags so that we can accurately monitor their weight gains.
The details of the trial are below:

Bill Conroy from “Annievale” went along to Tallangatta meats with Rene Stud and commented on how impressive the Body Shape, Carcass & Yielding was on the lambs. He also said that he was surpised how well the skins came off & the quality of the skins.
Bill is currently lambing out Charollais/Merino lambs and said “We are lambing out our Charollais/Merino lambs out of our finewool maiden Merino Ewes, the lambs are strong and healthy, there growth rate is huge and there fertility is like something I havent seen before with many sets of twins.” “I have left the Ewes alone while lambing and have yet not had to pull a lamb out” the quality of the meat is amazing too” Bill said
Will Smith from Tallangatta Meats commented when he saw the Carcass hanging up that he was very impressed with the shape in the hind legs and thickness of the carcass & he was surprised with the yield.
Both Will & his brother Ambrose (lamb buyer for Tallangatta meats) assessed the lambs before slaughter and didn’t believe any would go over 25kg (averaging 25.22kg)
He was also very impressed with the skin type with 50% going through as Merino skin.
