Abstract: A process for promoting growth and feed efficiency in food producing animals is provided by administering to such animals, growth promoting amounts of certain forms of lysocellin, including the free acid and physiologically-acceptable salts thereof.Metal complexes of lysocellin can be prepared by adding the appropriate soluble metal salts to a fermentation beer containing lysocellin to thereby form an insoluble, recoverable biomass containing the desired growth-promoting metal salt complex of lysocellin for use in the process herein.

Abstract: Crystalline lysocellin compositions, and method of making them. These compounds are useful for promoting growth and feed efficiency in food producing mammals by administering growth promoting amounts of the compounds to such mammals. In particular, the crystalline free acid and the crystalline zinc, copper and manganese of lysocellin can be made according to the disclosed methods.

Abstract: A growth promoting and feed efficiency-enhancing amount of a lysocellin material selected from the group consisting of lysocellin, lysocellin free acid, and the physiologically acceptable salts thereof is administered to a food-producing animal selected from the group consisting of ruminants, swine and poultry in a process for promoting growth and enhancing feed efficiency of such a food-producing animal.

Abstract: Control of parasitic worm (helminth) infestations in warm-blooded animals including poultry, swine, cattle, sheep and goats by administering substituted quinoxaline adducts to infested animals. In particular, certain adducts of quinoxaline-1,4-dioxides are capable of eliminating ingestations of the pinworms Syphacia obscelata and Aspicularis tetraptera in mammals. Several of the compounds are also effective against the tapeworm Hymenolepsis nana in mammals.

Abstract: Antibiotic-metal complexes contain bacitracin, a non-toxic, complex-forming metal and a polyether antibiotic are disclosed. The complexes are useful (1) for promoting growth in poultry and mammals, (2) for controlling swine dysentery, (3) modifying rumen fluid by decreasing the acetate to propionate (A/P) ratio, (4) controlling coccidiosis in birds, and (5) purifying bacitracin or a bacitracin-metal salt.

Abstract: Manganese complexes of various monovalent and divalent polyether antibiotics are provided which act as coccidiostats and growth promoting agents when administered to food-producing animals such as cattle, sheep, swine and poultry. Soluble manganese salt is added to a fermentation beer containing the polyether antibiotics to form an insoluble, recoverable biomass containing the desired manganese antibiotic complex. This biomass, in a dried form, can be given orally to animals such as cattle, sheep, swine and poultry.The subject manganese complexes include: linear monovalent and divalent polyethers (monensin, nigericin, lasalocid, lysocellin, etc.); non-glycolic monovalent monoglycoside polyethers (septamycin, dianemycin, lenoremycin, carriomycin and antibiotic A-204); mononitrogen-containing divalent pyrrole ethers (calcimycin, X-14547, etc.); polynitrogen-containing divalent pyrrole ethers (A-23187, etc.); glycolic monovalent monoglycoside polyethers (etheromycin, etc.
