My neighbor's new horses just arrived from Minnesota today - a mare and her colt. The colt is 5 months old and still nursing. When they arrived, the mare and colt both had significantly overgrown hooves (farrier coming tomorrow - colt never trimmed), and the mare has ribs, spine, hips, and tail bone all sticking out - you can tell she is quite emaciated from a distance. It is clear that she needs to be weaned immediately, but they are only a few hours in a new environment, and have not yet been introduced to her existing horses.
She has two pens that are adjoining (separated by electric), and then a totally out of sight separate pen. She also has three horses the new ones have not met yet (being kept in out of sight pen). Baby is very shy of new people, mom is very friendly.
I was just wondering what is the best thing for her to do quickly and safely (weaning and feeding)?
She was going to start them on beat bulp, and the haulers already started her on Omalene for mare and foal. She was on pasture in Minnesota.
