Breeding cows to be milked by robots
Dairyfarmers considering automatic milking systems (AMS) frequently ask what percentage of their herd will need to be culled as having udders that are unsuitable for robotic cup attachment. FutureDairy and Australian experience shows that very few cows have udders that are unsuitable for robotic cup attachment. However, when making breeding decisions, AMS herd managers may place more emphasis on some traits that influence the robot’s ability to attach cups and the cow’s ability to walk voluntarily around the farm, for example cow size and conformation of udder, legs and rump. Peter Williams, from the Australian Dairy Herd Improvement Scheme, will explain how automatic milking may influence breeding decisions at this year’s Dairy Research Foundation annual symposium, to be held at Kiama on 4 – 5 July. “I would encourage farmers with AMS to pay more attention to teat placement,” said Mr Williams. “Over many years there has been an industry – wide trend to bring the rear teats closer together, resulting in the potential for rear teats to angle and cross over. This would make robotic cup attachment difficult.” “AMS farmers who want to widen the distance between rear teats should select bulls from The Good Bulls Guide with a Rear Teat Placement ABV of less than 100,” he said.
