BREEDING OBJECTIVE

Glen Iris Bond Stud established its reputation as progressive with a breeding program that adopted eye muscle scanning technology more than 20 years ago. Identifying critical traits that drive profitability, we have nurtured and developed genetics that produce high performing sheep to give producers a multi stream income.

This commercial approach has been tried and tested by Glen Iris Bond Stud. Our ‘risk management’ enterprise has evolved into one producing high value wool and more lambs resulting in a reliable income stream.

Although scanning for eye muscle and fat depth has only become a recognised tool during the past 10 years, ‘Glen Iris’ sheep have been scanned for muscle and fat measurements since 1994.

Wanting to develop a flock with consistent and quality results in the pen and on the board, our vigorous screening processes have established a Bond flock with a fleece averaging around 23 micron and superior maternal and meat producing traits.

Better muscle and fat depth generates ewes with more energy. More energy has a positive impact on lamb survival and growth rates, making the ewes better mums.

Our lambs are maturing much quicker. Wether lambs are being sold over the hooks as heavy trades ie 22-24kg, and are now reaching those weights a full four-six weeks earlier than 15 years ago.

We also pay close attention to fat depth measurement. We do not want our sheep to be too lean – good fat cover is related closely to fertility and milk production. Some of our clients are now successfully joining ewe lambs and achieving excellent results.

From the outset, ‘Glen Iris’ stud sires and all stud ewes have been scanned and then mated the best to the best. We muscle scan the ewe hoggets selected for wool type, cut, shape and structure to come back into the ram breeding flock. They must meet the muscle depth benchmark or they are rejected and return to the general flock. The replacement sires are selected by the same criterion.

Our breeding program and selective processes have resulted in a much more profitable sheep that is increasingly more resilient to the climatic conditions of the South West Slopes and Riverina.

Our open flock policy enables comparison of performance, not just across our stud, but by benchmarking and performance testing of outside genetics. This allows us to be confident in the calibre of sheep we breed and the commercial viability of their progeny.

Glen Iris Bond Stud has a deep rooted and extensive history in the development of Bond sheep breeding in the Riverina.

The genetic gain through our enhanced muscling and fat cover is inherent and undeniable.

Wool

Glen Iris Bond Stud’s main fleece is sold as AAAM, and averages around 23 micron and 70-74% yield. We have successfully trialled 6 monthly shearing.

The stud has used objective measurement for its wool since the its inception. A well nourished, white, long-stapled (110-120mm), free opening wool stands up best in this eastern Riverina environment.

Our selecting for wool involves balancing several key criteria;

  • above average for clean fleece weight
  • average or finer for micron
  • a SD (standard deviation) below 5 and CVD (Coefficient of variation) below 20

(the lower the SD & CVD the better).

Fertility

The property runs a commercial flock of around 4,200 ewes. Of these approximately 3,000 are joined to Bond rams and the balance to Poll Dorsets.

We join our ewes for six to seven weeks during November/December and average between 125-140% conception at scanning, with 4-7% dry.

At weaning time all the ewes are checked and any ewe that has not reared a lamb is identified. If they fail to rear a lamb for a second time they are culled. At ‘Glen Iris’ we feel this method of selection not only identifies the breeders, but also the ewes with “mothering ability”. We want ewes with milk, and also the type that will stand over their lambs and protect them from predators.

Our long history (since 1994) of muscle and fat scanning has improved our fertility, as well as our lamb survival and growth rates. A ewe with good muscle depth and fat cover has a greater likelihood of successfully rearing multiple lambs, particularly in tough seasons.

Meat

In the early 90’s ‘Glen Iris’ was selling Bond wether lambs over the hooks. We asked the abattoir owner how our Bond lambs compared to second cross. He said, “Some of yours are very good – but there is more variation”.

We started scanning for muscle depth in 1994. The stud sires and and all the stud ewes were scanned then mated the best to the best. We now muscle scan the ewe hoggets that have been selected for wool type, cut, shape and structure, to come back into the ram breeding flock. They must meet the muscle depth benchmark or they are rejected and return to the general flock. The replacement sires are selected by the same criterion.

By selecting for muscle depth, our lambs are maturing much more quickly. ‘Glen Iris’ sells wether lambs over the hooks as heavy trades ie 22-24kg. They are now reaching those weights a full four-six weeks earlier than 15 years ago.

We also pay very close attention to fat depth measurement. We do not want our sheep to be too lean, and good fat cover is related closely to fertility and milk production. Some of our clients are now successfully joining ewe lambs and achieving excellent results.
