When a piggy needs syringe feeding I feel it's best to give it what it likes, if you can get it to eat without a fight you and piggy will both be happier for it. If you are only feeding for a couple of days then it matters less but if like me (too many times ) you're having to top up for weeks then me giving mine a feed based on alfalfa (not recommended for piggies) wasn't the smartest move. Last time I fed Peanut he got mushed pellets as a top up for a few weeks when the packet food I already had ran out, it did the job, kept him going, was a lot cheaper and he's still here!
