CytRx Corp.'s growth promotant copolymer promotes growth inchickens, the Norcross, Ga., company announced at its annualstockholders meeting..In a trial of 7,000 broiler chickens, the compound improved weightgain and feed conversion when added to a standard poultry ration.The improvement was about double that of bacitracin, a widely usedantibiotic feed additive, CytRx said last week..The exact mode of action of the complex copolymer molecule isn'tknown, said James Johnson, CytRx's patent counsel. But because thecopolymer passes through the bird and isn't absorbed by cells, thecompany believes it may act by stimulating immune tissues in thealimentary canal..CytRx has begun discussions with other companies interested inlicensing the product. The company estimated a market of more than$100 million for the U.S. broiler industry alone. It will be up to thelicensee to apply to the U.S. Department of Agriculture for marketingapproval..CytRx stock (NASDAQ:CYTR) closed at $2.06, down 13 cents, onFriday.
