I'm sure you might know me from another forum. . . . .
Exlana and Easy Care. Currently bred back to a shedding maternal ram, with the ewe lambs put to some charmoise, and this year a bunch of ewes to a NZ suftex.
Out of interest why 3-4 breeds and x breeds? Would it not be easier and more efficient to standardise your flock and keep a consistent and 'typey' ewe?
Having sat through various lectures / seminars I am lento believe that days to slaughter or 'days on farm' is the biggest key profit indicator for a number of reasons. With regard to grass, your most productive 'fattening' grass would be grown April - August, anything after that and the quality reduces etc. Also I guess there is the increased risk of disease, death etc, and also the possible need for extra interventions and products (strike prevention, worming etc). Also, over wintering fat lambs means less ewes can be over wintered. I also find that when I have lambs on, I have more mobs of sheep (ewes, ewe lambs, ram lambs etc), where as over winter I pretty much set stock the flock somewhere by a road and don't do much with them other than keep an eye out for anything sick / dead as I drive by. They are then gathered for scanning and the tups taken out, and we go on from there.
