Scopus, Givat Ram, Ein Karem, and Rehovot, Israel; coeducational. First proposed in 1882, formally opened 1925. It is the world's largest Jewish university and is noted for its work on the Dead Sea Scrolls. in Jerusalem, Israel, unveiled his coop of featherless chickens. He thinks the fluff-free breed, produced by his top-secret method of crossing a small bare-skinned bird with a regular broiler broiler a young (about 8 weeks old) male or female chicken weighing 3 to 3.5 lb. (raised for meat) chicken, could revolutionize the global poultry industry. "Feathers are a waste," Cahaner says. His no-pluck chickens can potentially reduce processing time, labor cost, and garbage. Also, broiler chickens are bred to heft up Verb 1. heft up - lift or elevate heave up, heft, heave upheave - lift forcefully from beneath weigh anchor, weigh the anchor - heave up an anchor in preparation for sailing quickly. "But in the process they generate a lot of heat," says Cahaner. Farmers keep broilers comfy by ventilating ventilating Natural or mechanically induced movement of fresh air into or through an enclosed space. The hazards of poor ventilation were not clearly understood until the early 20th century. Expired air may be laden with odors, heat, gases, or dust. their environment to approximately 20[degrees]C (68[degrees]F). "Otherwise their internal body temperature will soar and they die." In developing countries with hot climates, where air conditioning is costly, Cahaner thinks his featherless model could be highly cost-effective--the chickens keep cool and grow rapidly. "Obviously, these chickens aren't meant for the open fields of England in winter, says Cahaner." A naked bird may catch cold. |
