HELP!! too many open cows. Recently changed bulls. I thought the first one about had all the cows bred because I wasn't noticing much riding around. Enough to think that he was probably on the cleanup stage anyway. When I bought a couple angus and returned the other bull to my neighbor, all of a sudden I had a lot more cows coming in. What's wrong? This seemed to happen suddenly. If the bull was bad, why wasn't I noticing extra riding around? Was he just plum lazy? Think it might be lepto or some other reproductive problems? Think they might be aborting at a early stage? I haven't noticed anything. All comments will be greatly appreciated. I have contacted my vet and we are going to sleeve everything tomorrow to see what kind of % are open. Thanks so much!!!
