I d only use pp personally if a horse ever came here looking thrifty, not on a lami one.....if you want to get some good flora in there, use the yoghurt and also as a medium to get meds down theyre neck, i got one in now (one not even on my radar) , she can smell it in her food, so it down the hatch in a syringe tonight .. cleavers are being hoovered up a treat too....my two "watch like a hawk " ones are doing really well, soft and very fluid in theyre movement.....but as we know it s a very fine line this time of year.....
