Lighting programme in hot climate houses

 
Hendrix Genetics

 

 

The article first examines the correlation between temperature and egg-laying, with a chart showing that at a lower temperature of18 deg C, layers seem to grow faster compared to a higher temperature of 30 deg C.


The deterioration of the growth rate usually observed leads to a delay of  sexual maturity. Indeed, without any light stimulation, the pullets start in production when they reach their ideal bodyweight. The later this bodyweight is achieved, the later it will start egg production.


Therefore, it is essential the conditions of rearing and production to encourage growth is present during the whole rearing period. The article lists these conditions and goes on to explain why it is better to encourage growth rather than sexual maturity. It then provides a lighting schedule for layers in tropical and sub-tropical climates.
