For most of the year I use Hegates Hogget nuts as these can be fed to males as well as females. I use these to train the sheep to pen themselves and for fattening and finishing the castrates if they need it. For feeding to ewes before and after lambing I use Flockmaster 18 Nuts. Both of these feeds are of good quality and are gobbled up fast.
My sheep are Castlemilk Moorits and Cotswolds. The premium 20% nuts are for 'top performing flocks'. These may be good for high input, high output flocks but I am not certain they would suit my more slow growing breeds. What breed(s) do you keep and why do you want the higher protein feed?
