Once again, South Australia has reigned supreme in the ICSA Holzhauser production competition for the 2013 lactation year.

Of the first five placings, South Australian studs featured as four of the placegetters with last year's winners, J C Altmann & Sons (Blackwood Park Stud), again taking top spot as well as third position.

The Blackwood Park Stud's first team of ten cows averaged 12,614 litres at 908 kgs of Fat Plus Protein.  Their second string averaged 11,749 litres of milk at 849 kgs Fat Plus Protein.  Splitting the Altmann's teams was Ian and Julie Mueller of Glenbrook Stud, also of South Australia, with their team averaging 12,558 litres at 875 kgs F+P.

In fourth spot was C R Chittick Pty Ltd (Laurie & Sandra Chittick, Lemon Grove Stud) from Victoria averaging 12,245 litres for 833 kgs F+P.  Fifth placing went to South Australia's Treeton Stud (Geoff & Rosemarie Williams & family) with 10,599 litres at 823 kgs F+P.

The Holzhauser competition consists of teams of ten cows with placings based on the highest combined average total protein and butterfat content.  The 140 cows entered into the competition, averaged 11068 litres at 794 kgs of Fat Plus Protein.

An award is also given to the entry showing the greatest improvement over the previous year's average in combined total of protein and butterfat which this year went to Braelee Pastoral (David Kuhl) also of South Australia with Glenbrook Stud (Ian & Julie Mueller, South Australia) in second.
