Primeline Maternal Breeding Program

‘Performance and Consistency’

It’s the combination of performance and consistency that makes the PRIMELINE Maternal the largest supplier of maternal genetics to the Australian lamb industry. The breeding program is self-replacing focused on the production of moderate, highly fertile ewes with high muscle and tight skins. The outcome is cutting edge maternal genetics that maximise kilograms per hectare and dollars per kilogram.

The breeding program has been developed over the past ten years using the leading New Zealand Composite genetics combined with White Suffolk’s that rank highly for maternal traits.

The PRIMELINE MATERNAL breeding program focuses on creating highly productive ewes that can be run with minimal cost. The traits targeted are early growth, low adult weight, positive fat, high muscle, high milk and high number of lambs weaned through fertility, fecundity, mothering ability and lamb survival.

All sheep are measured in large contemporaries under commercial conditions. This allows the most profitable sheep to rise to the top and multiplied throughout the flock. Genetics are added from across Australia and New Zealand using artificial insemination and embryo transfer.

For our commercial clients the PRIMELINE Maternal self-replacing system enables them to make genetic gains annually and reduces the high capital cost of purchasing 1st cross ewes or the need to run merino ewes. The prolificacy of the sheep enable rapid build-up of the flock, and bio security benefits by not having to purchase in replacements.

The PRIMELINE Maternal is highly fertile at 7 months of age and has the potential to wean over 100% lambing as a one year old. LAMBPRO places heavy emphasis on lamb survival and with the right management, flocks are achieving in excess of 155-165% weaning.

Breeders can use merinos, 1st cross ewes or Coopworth’s as a base for a LAMBPRO Maternal self-replacing flock.

‘Business Driven Lamb Systems’

The Australian sheep flock has undergone a significant change in numbers and composition over the past decade. The decline of the merino ewe flock has created a shortage of breeding ewes available for prime lamb production. LAMBPRO started to look at genetics that enabled lamb producers to self replace in 2001. This followed years of development, which has culminated in the launch of the PRIMELINE MATERNAL in 2009.

Self-replacing lamb flocks have a number of benefits. Firstly they allow you to control the performance of your flock. The MLA Maternal Central Progeny Test program highlighted the top maternal genetics could add $35 per ewe per year to the bottom line of prime lamb flocks. By managing the genetic gains in your lamb flock has a big financial impact. Combine these productivity benefits with a reliable source of disease free ewes bred in your own flock and the self-replacing option becomes extremely attractive to prime lamb producers.

Self-replacing lamb flocks give producers a number of options in flock composition. The majority of lamb flocks join 50% of breeding ewes to maternal genetics to generate high performing replacements. The remainder are joined to terminal sires to maximise growth rate and carcase value.

The other option, which is growing in popularity, is to join 100% of ewes to a maternal sire. This allows breeders to capitalise on high ewe prices by selling a high number of surplus ewes.

LAMBPRO has been a key driver of self-replacing flocks and in the future we believe these genetics will be the backbone of the Australian lamb industry.
