There are different methods that are used to artificially induce molt ing; however, all are aimed at giv ing the flock a rest at the end of a period of egg production so that it may perform more efficiently dur ing a second cycle. The most common procedure, which is called “conventional,” provides no food or water for two days and is followed by providing water and 45 grams of feed/hen every other day for a period of one week. Oyster shell is provided on a continuous basis throughout the nine days. From days 10-60, water is provided continuously and each hen receives 90 grams of feed. During the 60-day period, the light received is reduced from 16 to 8 hours/day. Following the 60 days, the hens are put back on full-feed layer ration and light received is LANCASTER COUNTY POULTRY ASSOCIATION Affiliated With Pennsylvania State Poultry Federation For more information call John Schwartz, County Extension Director (717) 394-6851 V ,/",r How Insurance Companies View Farming Gregory R.

Another method used to induce molting is called “California” and incorporates a longer period of complete feed, withdrawal (10 days) followed by nothing but cracked com for 18 days. Water and oyster shell are provided for the total 28 days. As in the conven tional method, in the California program, light is reduced from 16 to 8 hours/day throughout the 28-day period. Following the 28-day period, the hens receive 16 hours of light and are put back on full-feed layer ration. The third method to induce molting is to use zinc at 20,000 ppm for S days and then back on full-feed layer ration. In our laboratory, we conducted an experiment to study the differ ence in the effects of the above mentioned methods of induced molting on subsequent perfor mance and on the immune response. White Leghorn hens were used following 12 months of production. Hens were divided randomly into four groups and the three methods of induced molting were applied to the first three groups. The fourth group was not treated and served as control. Body weights, egg production, egg qual ity, and immune responses were measured at different time periods. We found that relative to control hens, body weights of hens in the California program woe reduced the most and hens in the conven tional group were reduced the least during the treatment periods. At peak egg production, body weight of hens in all groups were similar. Egg production and interior egg quality were better in the conven- Nutrient Management ANNAPOLIS, Md.
