D44—Lancaster Farming, Saturday, Way 15,1982 ■ The Purina® Bio-Mittent Lighting Program is a unique lighting program for pullets and layers which saves energy and money without adversely affecting growth or egg production. It supplies pullets and layers with 15 minutes of light and 45 minutes of darkness each hour they receive light under a standard lighting program. This intermittent lighting program resulted from the discovery that chickens will grow and produce well when supplied 15 minutes of light per hour instead of 60 minutes.

The chicken’s hormonal reproductive control system does not recognize darkness unless she is without light over 3 hours. Thus, the dark periods are never perceived as such by the hen’s system. For Bio-Mittent Lighting to provide maximum benefits, light tight housing is required. In non-light tight houses, electrical savings are realized but feed savings are slightly less. In open-sided housing, the advantage is only electrical savings. However, this still can be significant. The function of a pullet lighting program is to control sexual maturity. As with a standard lighting program, on the Bio-Mittent Lighting program pullets receive constant light from 1-14 days of age. Afterwards, until 20 weeks of age, the Bio-Mittent Lighting Program is implemented. The intermittent pattern of 15 minutes light/45 minutes darkness per light hour is used during the time lights are normally used. When the hours of light are increased to stimulate onset of lay, constant light should be initiated and continued through 36 weeks of age. At which time, layers can gradually be phased onto Bio-Mittent Lighting. Intermittent lighting is continued throughout the laying cycle and can be used in the second cycle with comparable savings, if the flock is molted. PROOF OF PERFORMANCE Research Results Table 3.
