Collecting turkey-specific data

June 16, Elmhurst, Ont. – Ongoing research at the University of Saskatchewan is examining how light cycles can affect a bird’s natural rhythm, health and growth rate.
“Turning the lights off can have a dramatic effect on how birds move around in their environment,” Dr. Karen Schwean-Lardner, assistant professor in the department of animal and poultry science at the University of Saskatchewan, said.
Schwean-Lardner recently discussed her research study at New-Life Mills’ Turkey Producers Academy held in Elmhurst, Ont., on June 1. The research project initially examined how light cycles affect broilers and is now performing the same research study on turkeys.
“It is really important that we look at turkey data for turkey producers, not just take assumptions from broiler data,” Schwean-Lardner said.
Research results are suggesting the ideal amount of light per 24 hours for turkeys to be at least four hours of darkness.
“One of the primary differences between turkeys and broilers is that turkeys benefit greatly from four hours of darkness – and few differences are noted with the addition of more darkness. The exceptions might be in body weight, and if a producer has an issue with mortality or lameness, that will also be impacted,” she added.
It is also noted it is ideal to establish distinct day and night times and to implement increases and decreases gradually.
“If flocks have mortality issues, periods of darkness can certainly help that. If you are considering making a change to your lighting program be sure to do make your adjustments in the evening, before the period of darkness, to avoid interrupting the bird’s feeding cycle,” Schwean-Lardner said.
The New-Life Mills event also featured William Alexander, technical representative from Hybrid Turkeys. Alexander discussed factors that contribute to consistent quality poult starts and Lisa Hodgins, monogastric nutritionist from New-Life Mills, spoke on the evolution of feeding programs.
