Southwest MN | Drift lambing works well in a dry climate can be a challenge without years of selection. Let alone a wet muddy climate. Next step will be parasites. The main reason most lambs in the upper midwest never see grass. Its bad enough to keep them in an electric fence let alone trying to rotational graze with a single polywire. Next is eagles, vultures, and coyotes. Our lambs do not go outside except for when we are cleaning pens until they are a 100#. To many eagles to feed. Now if I could convince the eagles to kill coyotes we would be onto something. I am just happy we don't have wolves our bears in any large numbers yet!
Enough whining from me. Are you vaccinating ewes 4 weeks before lambing with cdt? If unsure of health status I reccomend treating that ewe like she has never had a vaccine. 2 rounds 21 days apart. I would do this at breeding and then booater before lambing takes about 4-8 weeks after 2nd shot to get to full immunity. Make sure if having trouble to vaccinate with a strain that has type a. As far as e coli did you send a lamb off to a university. Trueperella shows similar symptoms but death happens very quickly under 36 hours. Are these Hair or wool ewes? | |
