TAS Country : January 17th 2013
Friday, January 18, 2013 Tasmanian Country 9 The Stock Report Tests find top performers KAROLIN MacGREGOR BREAKTHROUGH: DNA testing could be labour saver. NEW Merino DNA testing could provide major labour savings and pro- ductivity increases. Leading Western Aust- ralian Merino breeder Mi- chael Campbell from the Coromandel Poll Merino Stud at Gairdner said geno- mics was an area that could improve pro- ductivity in a relatively short time. Mr Campbell has re- cently ordered 70 DNA tests as part of the Cooper- ative Research Centre for Sheep Industry Innovation Genomics Pilot Project. Mr Campbell said he hoped the tests would help identify his top-performing stock. ''Down the track we see major savings in labour in the areas of data collection and establishing parentage through mothering up, and if they can develop gene markers for worm- resistance, that would pro- vide a big saving in terms of conducting egg counts,'' he said. Over the past 20 years the Coromandel ewe flock average fibre diameter has fallen from 22 microns to 19 microns. To do this Mr Campbell has used a range of performance-enhancing selection tools, including traditional subjective measurements, fleece weights, micron measure- ments and Australian Sheep Breeding Values. The stud has also used embryo-transfer programs and now DNA research. Using embryo-transfer programs over the past eight years has increased the rate of key productivity traits, including growth rates, muscling and fleece. Recently the stud was asked to become involved with the Genomics Pilot Project by providing se- men from one of its stud rams. The ram was used as part of the project's flock nucleus and that data has assisted with the develop- ment of research breeding values to detect to presence of various genetic traits. Some of that ram's sons have now also been DNA tested to help improve the accuracy of the RBVs. Last year's genomics project resulted in RBVs with accuracies of 69 per cent for greasy fleece weigh, 77 per cent for mean fibre diameter and 64 per cent for yearling weight. These figures are ex- pected to improve as the results of the 2012 rounds of tests come through. Mr Campbell has been involved with all three genomics projects so far and this year will use full genotyping and parentage tests on 70 select rams, ewes and young progeny. The parentage test will be used to identify the top- performing lambs for use in ET programs, as well as identifying superior rams from their syndicate mating programs. ''The parentage test will be very useful in saving labour in mothering up,'' Mr Campbell said. ''We mostly single mate, but last year we did put full brothers out together and those lambs were born in August. ''To see which sire pro- duced the better animals will be quite useful. ''If you can identify your improving animal you speed up the rate of genetic gain quite quickly.'' Mr Campbell said while the development genomic research data had not changed his breeding ob- jectives, it had added an- other layer of information into the selection process. He said the aim was to breed sheep with good per- formance figures in the areas of growth, muscling, fleece weight, staple strength and worm- resistance. ''We have to keep the animals productive value high with a good quality fleece, we want to identify animals that deliver that,'' Mr Campbell said. ''We're trying to find the breeding animal that's positive on all traits, but we have to be careful not to use extreme animals. We'll use whatever tools are available, but I won't use an animal if it has high ASBVs and doesn't fit into my selection criteria.'' The DNA tests will also help identify pure poll (PP) genes in his stock. Beef over sale status claims ROGER HANSON CONCERNS have been raised over adult dairy cattle agistment on farms with Beef Only status. The Department of Primary Industries, Parks, Water and En- vironment (DPIPWE) said it had received re- ports of beef producers in the North-West taking adult dairy cattle on agistment yet claiming to be ''Beef Only'' on their Cattle Health State- ment when selling live- stock. DPIPWE said the Cat- tle Health Statement was a legal document and the producer sign- ing it was declaring the information on the state- ment was correct. The four criteria a producer must satisfy to be able to claim Beef Only status are detailed on the back of the state- ment form. If farmers have agist- ed adult dairy cattle in the last 12 months, or agisted any dairy cattle or first generation dairy- cross cattle in the last five years, a Beef Only status cannot be claimed unless those dairy cattle were part of a Cattle- MAP herd. CattleMAP is Aust- ralia's Johne's Disease Market Assurance Program for cattle. It is part of the natio- nal effort to control Jo- hne's disease. DPIPWE said buyers and the beef industry needed to be confident that cattle offered for sale as ''Beef Only'' were what was claimed. Farmers, if intending to claim Beef Only status on the Cattle Health Statement, are reminded to check the back of the form to ensure under- standing of what it means and to meet all four of the criteria.
