Lynley Wyeth, a farmer from near Masterton, and John Smart, a well-known vet from Balclutha, discuss care of newborn lambs, treating those that are unwell or hypothermic, and rearing orphan or surplus lambs.
Lynley rears several hundred lambs each year from new-born to weaning, while John has led work to find ways to save lambs and keep them healthy.
