Abstract:
1. The effect of light intensities from 10 to 700 lux on the performance of 5 to 18 week-old turkey males was studied in 2 trials. 2. Body weight of 18 week-old turkeys, in both experiments, was highest under the lowest light intensity. This coincided with higher weight gain and lower food intake, which resulted in significantly better food conversion efficiency. 3. Light intensity affected heart muscle weight but not weight of breast muscle, abdominal fat or testis as proportions of body weight. 4. The decline in plasma T3 concentration with age differed from other treatments at the low light intensity, which resulted in a significantly higher T3 concentration in turkeys exposed to 10 lux at the age of 10 to 15 weeks. 5. It is concluded that light intensity significantly affects food conversion efficiency in turkey males, this is likely to be related to differential investment of energy expenditure for maintenance. © 2000, British Poultry Science Ltd.
