摘要

New range houses have been built, and workers are preparing to run utilities and install fences for the range pens at the North Carolina Department of Agriculture and Consumer Services Piedmont Research Station located just outside Salisbury, N.C. ThePiedmont Research Station has been home to the North Carolina Layer Performance and Management Test, an ongoing project that allows primary breeders to submit their strains for comparison with other breeds in a variety of housing environments, since 1958.Dr. Kenneth Anderson, poultry science professor, North Carolina State University, became project leader for the test in 1990. He said the layer performance test is unique not just for its longevity, but because it records performance data for brown and white egglayers of just about every commercial strain in housing options that are of interest to today's poultry industry. The 38th test offered breeders the option of testing their strains in conventional cages, cage-free (floor pens) and free-range (range houses with attached fenced pens). For the 39th test, for which eggs were set in July, enriched and enrichable cages have been added to the housing options.
