TAS Country : May 24th 2012
Friday, May 25, 2012 Tasmanian Country 23 The Stock Report SMART: Tori Scott has found that a feedpad with flexible access can be a useful tool for encouraging higher levels of intake of supplementary feed. It's food for thought in milk industry THE location of a feedpad in an automatic milking system (AMS) can be a useful tool for encouraging higher levels of intake of supplementary feed, according to recent research done by the FutureDairy team. Postgraduate student Tori Scott in- vestigated how the location of sup- plementary feed affected the time it took cows to move back to the paddock after milking and the time taken to return for their next milking. Her findings suggest that a clever design for an AMS with a feedpad would position the feedpad with the flexibility to divert cows to supplemen- tary feed either before or after milking, depending on the need. This may may change throughout the season. It could even be possible to give some individual cows or groups of cows access to the feedpad before milking while others could use the feedpad after milking. Automatic milking systems usually have programmable drafting gates which would allow this to happen. Feedpad management could be modi- fied to meet different objectives within the system. For example, the decision about which cows to feed before or after milking would come down to the desired level of supplementary feeding and the preferred flow of cow traffic through the dairy. Feeding after milking is the pre- ferred option when the herd's intake is predominantly pasture, and the sup- plement fed at the feedpad is a top-up. This option enhances cow movement through the dairy and maximises grazing opportunity. In contrast, feeding cows before milking could be a useful tool for encouraging cows to spend more time on the feedpad -- for example if pasture availability is limited, Ms Scott said. Scientists scan for juicy and lean lamb chops WE all love lamb but consumers are looking for leaner chops and now science has come to the rescue. Farmers have a new tool to help them choose sheep most likely to produce the lamb people want -- and it all started with a machine that has transformed medical testing, the CAT scanner. PhD student Fiona Anderson, from Western Australia's Murdoch Univer- sity, used the CAT scanner to check 2000 lamb carcasses, to accurately work out how much muscle, fat and bone they had. The result is a new way to identify the sheep most likely to breed juicy and lean lambs. ''We have so far scanned over 2000 lamb carcasses here at the Murdoch University and the University of New England in Armidale,'' says Dr Ander- son. ''We then used this information to see which of the current selection criteria (Australian Sheep Breeding Values) used by farmers most accu- rately selects parents that produce the highest yielding lambs.'' Preliminary results suggest farmers can produce larger and leaner loin chops from their lambs by selecting for the trait post-weaning eye muscle depth (the PEMD -- breeding value). Lamb carcasses bred from top rams for this breeding value had greater lean meat yield and a redistribution of muscle from the lower priced fore- quarter region to the higher priced saddle region. ''Obviously this is good for the farmer and processor who are both after a more profitable, larger, leaner animal. We are now making sure that selecting for these traits will not compromise the eating quality of the final product,'' says Dr Anderson. She has been collaborating closely with Meat and Live Stock Australia and dozens of Sheep CRC scientists around Australia. ''The key aim of the Sheep CRC is to improve lean meat yield and maintain or even improve eating quality,'' says Sheep CRC meat program leader Dave Pethick. ''Over the last 15 years, the industry has been increasing the average per- centage of lean meat per lamb by 230g, largely through genetic gain. ''This increase has been the major reason for the turnaround from lamb's lack of appeal and regarded as a fatty meat to being considered the premium lean meat. ''Before Dr Anderson's project we didn't have the data to see how far we as an industry had come. Now we have the data, and the tools to select for desired traits, we are in a strong position to keep improving the indus- try and our product.'' 2034185-120525 200 AI cross-bred heifers due 15th July on. $1350 +gst 25 cross-bred cows in milk, due to calve September 20 on $1450 +gst 10 Jersey heifers, Autumn calved $1100 +gst 35 cross-bred heifers (some Jerseys) due Spring $1300 +gst 11 cross-bred heifers due spring $1300 +gst 18 cross-bred heifers $1450 +gst 300 cross-bred heifers due Spring $1400 - 1500 +gst 40 Friesian Heifers due Spring $1900 +gst 22 cross-bred heifers $1500 +gst 3 18mo - 2yo Jamena bred Hereford bulls $1500 + gst Qty of Friesian bulls $1200 - 1500 +gst Qty of Friesian bull Autumn calves. 100 - 110kg. $280 - 300 +gst 22 Jersey heifers $1200 +gst 60 cross-bred calves, 5 months old $500 +gst 10 mixed age Friesian cows calving to Hereford 9th June $1200 +gst 40 Friesian cows, mixed age.
