Compatibility studies of ionophore anticoccidials with various antibiotics and chemotherapeutics in broiler chicks. Frigg, M.; Broz, J.; Weber, G. (Dep. Vitam. Nutr. Res., F. Hoffmann-La Roche and Co. Ltd., Basel CH-4002, Switz.). Arch. 57-68-1 and 55134-13-9 are cas registry numbers of chemicals which are used as reagents here. Gefluegelkd., 47(5), 213-20 (English) 1983. CODEN: AGEFAB. ISSN: 0003-9098. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) The compatibility of ionophore anticoccidials (lasalocid [11054-70-9], monensin [17090-79-8], salinomycin [53003-10-4], and narasin [55134-13-9]) with antibiotics currently used for prophylaxis and treatment of avian mycoplasmosis (tiamulin hydrogen fumarate [55297-96-6], erythromycin [114-07-8], kitasamycin tartrate [37280-56-1]) and with therapeutically used sulfonamides (sulfaquinoxaline [59-40-5], sulfamethazine [57-68-1], sulfadimethoxine [122-11-2]) and nitrofurans (furazolidone [67-45-8] and furaltadone [139-91-3]) was studied in broiler chicks. Of the anticoccidials tested, only lasalocid was compatible with tiamulin. Monensin was also not compatible with the 3 sulfonamides tested; however lasalocid was compatible with these drugs except for sulfadimethoxine. Neither monensin nor lasalocid adversely interacted with kitasamycin or with either of the nitrofurans. .

The selective capacity of pig feed additives and growth promotants for coliform resistance

The selective capacity of pig feed additives and growth promotants for coliform resistance. Mee, B. J. (Dep. Microbiol., Univ. West. Australia, Nedlands 6009, Australia). Antimicrob. Agric., Proc. Int. Symp. Antibiot. Agric.: Benefits Malefits, 4th, Meeting Date 1983, 349-58. Edited by: Woodbine, Malcolm. Butterworth: London, UK. (English) 1984. CODEN: 53CUAK. DOCUMENT TYPE: Conference CA Section: 18 (Animal Nutrition) Tests (20 wk) with Large White pigs in which resistant caliform bacteria were recorded after feeding growth-promoting substances indicated that mixts. of growth promoters were undesirable in feeding pigs. High selective resistance was obsd. with neomycin [1404-04-2], progen [98-50-0], sulfadimidine [57-68-1], lincospectin [57456-42-5], terramycin [79-57-2], neoterramycin [8057-00-9], neomycin plus terramycin, and tylan [1401-69-0] plus sulfadimidine; thus, these individual substances and mixts. were also not recommended for feeding to pigs. Intermediate resistance was obsd. with dimetridazole [551-92-8], lincomycin [154-21-2], neftin [67-45-8], roxalin [95033-08-2], and roxazole [95033-09-3], and low resistance was obsd. with avotan [37332-99-3], bacitracin [1405-87-4], bayernox [23696-28-8], dynamutilin [55297-96-6], flavomycin [11015-37-5], hygromycin [6379-56-2], mecadox [6804-07-5], neomycin, nitrovin [804-36-4], oleandomycin [3922-90-5], stafac [11006-76-1], and tylan.
