I have been breeding & showing lambs for years . Southdowns, Medium Wool & Finewool.. I maintain a regular exercise program, water,dry hay & alfalfa daily, have used, Essential Feeds, MFM Feeds, Showmaster Feeds, and just about any that was within a 50 mile radius. The last few years I have used Xcalibur supplement as a top-dress, and it seems that is has been discontinued now ugh.. Any suggestions on a last 60-90- day feed supplement for muscle building and smooth hide? Thanks.
