Sire Trial

Stockman Stud has always been focused on continually improving our selection process and breeding program.  We have always used mid-side sampling as a major tool in our selection process.  A number of years ago we included fleece weight and body weight data as an addition to this and now we have gone one step further by actually testing our rams genetic potential to ensure that we are selecting the best possible sires.

Sires from this years sire trial

Since 2002 we have been testing our top young rams against other high ranking rams throughout Australia.  The most effective and accurate way of doing this is to compare the progeny of these rams.  Through the use of AI and DNA sampling we are able to mate 7 young Stockman rams and three proven sires to a group of randomly selected ewes and record their progeny's results. 

The progeny from these rams are run together to eliminate the effect of environment on the results.  The progeny are then visually classed and objectively measured and these results and these results are combined in assessing the performance of the different sires.

We have five years completed results and we have visually classed the sixth year’s progeny.  The three standout rams over the completed trials have been 00-0378, OP 14 and Willy.  OP 14 has been a long-time sire of the stud and 00-0378 has been used extensively on the basis of these trial results.  02-0326 or Willy who is a top performer in the 12% Index.
We believe that the use of this trial program gives us the confidence and security to progress the genetic base of Stockman Stud to the next level.  By combining visual (subjective) and measured (objective) testing we have identified the most productive and structurally sound sires to ensure that Stockman Stud will capitalise on genetic gains at the fastest possible rate, further increasing profitability for us and our clients.
