We recently had two 6 month old lambs slaughted. When we went to collect them the buther told us they were very fatty. Indeed they are. We raised them on fresh cows milk till about 10 weeks, they had calf starter pellets but not a lot during this time. In the last few months of life they only grazed on grass with our cattle. How come they got so fat, does one have to restrict their food intake or slaughter them earlier?
