[Efficacy of aerosol disinfection with lactic acid and its effect on the body of poultry].

Comparative studies were carried out to establish the efficacy of lactic acid as a disinfection means. The following pattern was observed in employing the agent: a 20 per cent conc. of the acid at the rate of 20 cu. cm per cubic meter is dispersed three times as an aerosol (at 8, 12, and 6 oclock) in the course of twenty minutes. It was found that the microbial contamination of the air drops three to four times. More pronounced is the bactericidal effect on the coliforms and moulds. The birds of the group treated with lactic acid gain 30 g more per day up to the end of the fattening period. Dependable is the higher serum level of protein as well as the higher protein content of the liver and heart musculature and of the essential amino acid tryptophane in the blood serum and liver of the test birds. Higher was also the glycogen content of the liver of the test group broilers.
