High quality, easy-mix first day colostrum in pre weighed single feed (25g) sachets. Providing energy and support to weak and small lambs. Ultra Concentrate mimics the ewe?s own colostrum in every way possible and should be used when no or insufficient maternal colostrum is available. All Nettex colostrums are made from natural, full fat colostrum sourced exclusively from TB & EBL free UK farms meaning it is highly complementary to UK farm environments.
