[Effect of the bacterial count in the air on chickens and laying hens raised commercially].

Abstract

Investigations were carried out to establish the amount of bacteria in the air on the premises for raising young birds and laying hans as well as in the respiration organs of the birds. Attempts were made to lower the microbism on the premises through the aerosol spray of Lugol solution. It was found that under industrial conditions there existed a rising trend with microbism both on the premises and in the respiratory organs of the birds, parallel to the advance in age which contributed to the enhancement of mortality rate and the drop of productivity. The use of Lugol solution in the form of spray was shown to produce a favourable effect on the health and productivity of birds.
