In animals and humans, mother's milk produced in the first couple days after birth contains powerful disease-fighting antibodies.
Kittens depend on the early milk, known as colostrum, for protection against serious infections.
Now antibodies found in the blood of normal adult cats can be transferred to kittens by injection, report researchers at the University of Florida College of Veterinary Medicine. The process could be used to save newborn kittens of endangered cat species, such as panthers. Unlike human babies, who acquire some antibodies via the placenta before birth, newborn kittens' immune systems are undeveloped and the animals, like other species, rely on passive transfer of antibodies through colostrum. We believe that at least some of these kittens were susceptible to infection due to their inability to acquire important antibodies from their mothers. Dr. Urs Giger, professor of medicine and chief of medical genetics at the University of Pennsylvania School of Veterinary Medicine, said studies such as Levy's are important in documenting how the newborn kitten's immune system works.
