I was reading some past comments on Laura Matthews blog about her Coopworth ram and how the Coopworth registry has a mandatory 75% cull rate in rams and 30% cull rate in ewes.
When I first read it, I was like WOW that's a pretty serious number for rams, but then went back to my breedings in the past. In cattle our cull rate was 25% for heifers and 95% for bulls. We typically kept most of our heifers for replacements. If they didn't work out, they were sold. Our bulls we are/were extremely picky about. This year my cull rates for the heifers was 50%, and the bulls 95%. I kept only one bull and 2 heifers. Since I only ended up with 4 heifers, and sold two, that would be the 50% :)
In sheep in years past my cull rate was 35-60% in ewes and in rams 50-100% in rams. My first year I culled all of my rams ( I ate them) and same as my 2nd year. I did winter some over to eat them, but never used any for breeding, even though I did registere a few. This year I kept back 50% of my ram lambs as over half of them were from AI and they were the last of those bloodlines. I want to grow them on to see how they develop and compare them to the lambs that are born next year from AI.
It would be interesting to see what Shetland or BFL people do for culling %'s. I bet some Shetland breeders have zero culling as they either don't breed, or they can't part with any as they are their pets :) Its a bummer that Shetlands are not more based on production like other breeds of sheep that are considered livestock, and not pets. I think we'd see improvement a lot faster in them if they were not pets first and kept because they are cute or friendly. Even if they aren't registered, I don't think that constitutes culling?
What are your percentages?
