“I think the ASBVs will take industry to another level, as they’ll take the guesswork out of indexing and selecting stock.”
- Sheep Classer and South African Merino Meat Sheep (SAMM) Stud
- Sues objective measurement with visual appraisal
- Reduces fleece micron from 23-26 to 20-21 over eight years
- Increased fertility and improved numbers of lambs weaned per ewe
- Rapid increases in growth rate and eye muscle area, reduced fat cover
With a watchful eye on two industry sectors, sheep classer and South African Meat Merino sheep (SAMM) breeder Philip Russell is well placed to observe the values of objective measurement in Australian sheep industries.
Philip has been using objective measurement procedures on his stock and on his clients’ stock for nearly 20 years, and has found it to be a valuable breeding tool.
“In my role as a classer, and prior to the Optical Fibre Diameter Analyser 2000 (OFDA 2000), I was simply using scales to measure body weight and recording that along with all the fleece data I could gather,” he said.
“Currently I use the data collected from my Merino stud clients to monitor trends for body weight, micron, wool type, fleece weight and a host of other information to isolate different families within the stud.
“Gathering this level of data helps the studs to identify different traits in the families and decide which direction they would like those families to go genetically”, he said.
Through his work Philip is finding ram buyers are increasingly demanding objective measurements to assist in their selection process, including body weight, micron, clean fleece weight and coefficient of variation.
As for his own stock, Philip has seen direct benefits from using breeding values and genetic data in the selection of his own SAMM ewes and sires.
“The opportunity is there to make big gains from using objective measurements, though they are best used in conjunction
“The ASBVs will also be a way to link Quality Assurance programmes that currently exist throughout the industry and guarantee Australian sheep meat and wool products.”
Sheep Genetics Australia is a joint venture between Meat and Livestock Australia and Australian Wool Innovation aimed at boosting productivity in the industry.
It includes the development of a single national language, Australian Sheep Breeding Values (ASBVs), for traits that have commercial impact.
ASBVs will be underpinned by standards for linkage, accuracies and QA principles, and they will enable the provision of elite and trait leader summaries. with traditional visual appraisal methods,” Philip said.
“We’ve been able to increase growth rates, increase eye muscle area, reduce fat cover, increase fertility and improve the number of lambs weaned per ewe.
“And by using LAMBPLAN with our SAMMs we’ve been able to achieve those significant gains easily and quickly, which is extra important in establishing new breeds.
“I have also seen 23 to 26 micronproducing flocks lowered to 20-21 microns over an eight year period, without losing fleece weight and body weight!
“This means we can achieve far bigger returns per hectare, which is a great result for any producer,” he said. Philip believes the introduction of Sheep Genetics Australia’s (SGA) Australian Sheep Breeding Values (ASBVs) will benefit the entire industry, both commercial and stud breeders and buyers.
“Objective measurement is a great tool, and having worked with it for nearly 20 years I am fairly familiar with it, but even I am still learning all the time, though the principle is gaining such wide acceptance”, Philip said.
“I reckon something like 80% of my merino clients are now using OFDA 2000 while they’re classing; ten years ago maybe 5 % of my clients were making those sort of measurements – that sort of uptake speaks for itself.
“Though I think the ASBVs will take industry to another level, they’ll take the guesswork out of indexing and selecting stock.
