Fi§er A.: Disinfection of Air and Dust in Fattening Houses for Chickens by Lactic Acid Aero~ol
The carriers were immerged into undiluted phosphate buffer in order to interrupt the action of the lactic acid, and, after 10 minutes transferred to meat-peptone broth or, in the case of E. coli strains, to Chejfec substrate
From Tab. 1 it is evident that all strains protected by agar layer survived 30 minutes and 48 hours following disinfection in spite of the high doses of 720 to 787 mg/m3 of lactic acid sprayed
Summary
Fi§er A.: Disinfection of Air and Dust in Fattening Houses for Chickens by Lactic Acid Aero~ol. In trials carried out in housings with chickens kept on bedding, amounts Qf 1,535 mg lactic acid pel 1 mS were administered on days 15 and 25 respectively, and, of 420 mg/m3 on days 29 and 51 respectively. Two different patterns of continual air disinfection by lactic acid were tested in fattening houses for chicks. The differences were of no economical significance With both programs, the mean consumption of lactic acid was 90 mg/day. Being an intermediary product of metabolism, lactic acid belongs to the preparations convenient for continual disinfection of byres with animals housed during its administration. According to Va§kov and Astafjev (1951) in Janikova (1970), vapour of lactic acid in the concentration of200 mg/m3 air showed no toxic effect on laboratory anim'tls even when systematically administered for several months. Doses ofapproximately 50 mg/m3 were administered in animal housings (Jarnych 1972; Vorobjev 1973) and, for food storehouses, MatyU (1958) recommended 95-150 mg/m3
