LIGHTING AND VACCINATION - GROWERS

Lighting - Growers

• If natural day length remains constant around 10-12 hours per day or decreasing during growing period, no artificial lighting at roof level is necessary. If the day length is increasing, then start giving additional lighting so as to maintain constant day length during growing phase. If necessary, repeat debeaking at 12-14 weeks of age following the precautions already given.

Vaccination - Growers

• Fowl pox vaccine has to be given on 10^th week by web-puncture method. Vaccine against infectious bronchitis is recommended between 12-13^th week depending on the need.
• RDVK/R₂B vaccine against Ranikhet disease should be given at 16/17^th week of age by S/C route as injection.
