Re gloves - you should always use them, I for example have not yet jagged a ewe after helping with a mispresentation, I always have a clean glove in my pocket - it means if I am busy with something nearby (I also have goats kidding at the same time as lambing, plus getting the garden sorted etc etc) I can quickly put on a glove and help without having to try and wash my hands, clean finger nails etc etc.. Really the price of gloves (I am still on my first box after 4 years of lambing and they don't go off) is minute compared to the possible loss of a ewe/bottling her lamb(s), so i don't think there is an excuse.
Bactakil comes in a handy spray bottle, doesn't mess your fingers up or the lambs belly (Don't get the purple version though), good allrounder for the holding.
