§ Major GLYNasked the Minister of Agriculture whether the inquiries by the Ministry into the advantages of ultra- 2567W violet rays for poultry have confirmed the benefits claimed by European experimenters that egg production is increased by 80 per cent. and fertile eggs by 34 per cent., while the mortality among young pullets is greatly diminished; whether it is his intention to have demonstration plants available for inspection by poultry farmers; and, if so, what steps he proposes to take?
§ Dr. ADDISONThe results of experiments in the irradiation of poultry by ultra-violet light have been brought to my notice. There does not appear to be sufficient evidence that under normal commercial conditions any benefit is to be obtained by this means beyond that which will result from a healthy open-air environment. The experiments have received considerable notice in the Press and no special action is called for on the part of the Ministry.
