Скачать или смотреть ClipFitter evaluation

Sandy Storrar has fitted rubber rings at birth to half his flock and is now fitting clips to the other half at 6 weeks of age. He will compare weights at weaning time to establish if there is a difference between the groups. UPDATE: It turned out that there was no massive difference in weights - with Clipped older lambs achieving only 1% higher weights at weaning. Perhaps the real difference will be found when rings and clips are used at the same time. The avoidance of a prolonged 'check' should gives those lambs a chance to thrive. The premise that lambs left entire would grow more especially if 'kindly' castrated later, was not proven this time. Worth a try although SO many other factors are involved, aren't they !
