Milk-Fed Calves Have Fewer Worms; Same Effect Noted for Swine, Rabbits Calves that get milk in their diet are likely to have fewer worms than calves given no milk at all. USDA scientists report this finding from a long time senes of small-scale experiments at the Regional Animal Disease Re search Laboratory, Auburn, Ala Calves on milk harbor fewer worms of certain economically important species, say ARS para sitologists G H Rohrbacher, Jr, D A Porter and H Herlich Fur thermore, milk seems to stunt the v'orms’ growth These results suggest that giv ing calves milk longer than usual might eliminate the need of early treatment for worms Adding milk lo the diet improves gams, too. THE AUBURN EXPERIMENT began with Porter’s work on 10 calves raised free of parasites, then paired according to age at seven to 17 weeks One calf from each pair had been raised on milk alone, the other got grain and hay along with milk All were infected with larvae of large stomach worms and killed four to five weeks later The calves that had received only milk had smaller worms and far fewer of them, even though the restricted diet didn’t allow these animals to gain as well as those that also got hay and grain. In a similar test, calves on milk, gram, and hay were com pared with calves weaned at 12 to 16 weeks. All were infected and killed a month later.
