Polychlorinated Biphenyls Influence on Hatchability ,
Poultry Science, 1973 Abstract Broiler breeder hens and Leghorn hens fed a diet containing 20 and 50 p.p.m. polychlorinated biphenyls (Aroclor 1242) for one week had their hatchability (percent hatch of eggs set) reduced to 67.3 and 26.8 percent, respectively, of control hens. The hatchability of the broiler hens fed 50 p.p.m.
