TAS Country : November 24th 2011
14 Tasmanian Country Friday, November 25, 2011 News Twenty-year-old embryos used for calves SUCCESS: One of the embryo calves bred at Heath and Samantha Dobson's Pine Park Charolais stud. Picture: Karolin Macgregor KAROLIN MacGREGOR 'We weren't sure how they would go because they've been sitting in the tank for over 20 years, but it's a pretty good result' TWO Charolais calves first conceived almost 22 years ago are proof of just how successful artificial breeding can be. The bull and heifer calves were born in September this year at Heath and Saman- tha Dobson's property at Cluan. They were the result of an embryo transfer program the couple included as part of their Pine Park Charolais Stud breeding program last year. Mr Dobson said they had some spare recipient cows at the time, so they decided to give the embryos, produced more than two decades ago, a try. Five of the embryos were implanted, which has so far produced two calves with another one due in January next year. ''We weren't sure how they would go because they've been sitting in the tank for over 20 years, but it's a pretty good result,'' Mr Dobson said. It is believed that these could be the oldest em- bryos successfully im- planted in Tasmania. The embryos were of- ficially conceived on Janu- ary 23, 1990. ''There would definitely be older em- bryos out there, but as far as we know there aren't any older ones that have actually been used and produced calves,'' Mr Dobson. Mrs Dobson said despite their age, the calves' genetics were still very much sought after. ''Now we've actually got them, we've found there's still quite a bit of demand for these older bloodlines,'' she said. The calves were sired by a well-known Canadian bull at the time called Triple J Pacman and were out of the Dobson's original Nolette cow, which has gone on to become one of the stud's most successful cow families. Mr Dobson said it seems to have been a good combination. ''It will just be interest- ing to see later on how they perform especially compared with the more mod- ern genetics in the group.'' The couple have ramped up the stud side of their operation in recent years in response to an increasing demand for bulls. Mr Dobson said most of their bulls were now sold to commercial pro- ducers to breed cattle aimed at the short-fed or grass markets. ''Our breeding objec- tives haven't really changed over the years, they've stayed pretty much the same,'' he said. ''The beef industry now is all about cost of production, so we are trying to breed bulls that can produce calves for different markets and make people money.'' The Dobsons also established a Red Angus stud about 12 months ago and are using those genetics combined with the Charolais to breed some composite bulls. They have increased their annual bull sales significantly from between three and six bulls a year five years ago and will offer about 20 at their sale in March 2012. New herbicide launched to control ryegrass PREPARING for next year's season, Bayer Crop- Science has registered its pre-emergent ryegrass herbicide Sakura. ''Australia is the first country in the world to bring Sakura to market,'' Bayer CropScience manag- ing director Joerg Ell- manns said. Sakura, based on the active ingredient pyrox- asulfone, has demon- strated up to 97 per cent control of populations of annual ryegrass, which are resistant to Group A, B and D herbicides.
