A farmer would cull, and be right to cull. As smallholders we can choose to give her another go, being aware that she has an increased likelihood of having milk failure, poor milk and or mastitis again. If you have the ability to monitor closely and take whatever action is needed should she have any of these problems, then it’s your choice whether you do so. I wouldn’t, as I’ve always got promising youngsters I’d like to keep, so I’d sooner always be selecting for trouble-free lambings and lamb rearing. And, having kept such a one on earlier in my farming career, I don’t enjoy watching an animal suffering from a predictable complaint. Mind, I never enjoy culling an apparently fit animal either, so it really is a personal choice.
