Abstract: The invention is directed to a lightweight steel frame system having end nailed connections where lightweight steel structural members frame into support members. The end nailed connection is made by driving fasteners through the support member and directly into the connection end of a lightweight steel structural member without the need for using additional connection hardware. Where the lightweight steel structural member is a roof or floor truss, the support member may include a leveling member to facilitate positioning each roof truss at an elevation set point to produce a level roofline along the finished structure.

Abstract: The invention relates to a method for the control of Arizona hinshawii in poultry, and especially in young turkey poults, comprising administering to the birds parenterally an effective amount of an alkylated BM123.gamma.-type antibiotic, preferably isopropyl BM123.gamma.. The invention further relates to a method for the control of transmission of A. hinshawii via the eggs of the birds, comprising contacting the eggs of the birds with solutions of the antibiotics. The invention also relates to alkylated BM123.gamma.-type antibiotics, and especially to isopropyl BM123.gamma. useful for the control of Arizona hinshawii.

Abstract: The invention is a method for the control of Mycoplasma hyopneumoniae in swine, comprising administering to the animals parenterally or orally a pharmaceutically effective amount of an alkylated BM123.gamma. type antibiotic or pharmaceutically acceptable salts thereof. The invention further relates to alkylated BM123.gamma. type antibiotics or pharmaceutically acceptable salts thereof, useful for the control of Mycoplasma hyopneumoniae.

Abstract: The invention is a method for the control of Bordetella bronchiseptica, the bacterial organism causing atrophic rhinitis in swine, comprising administering orally, or parenterally a pharmaceutically effective amount of Antibiotic BM123.gamma. in, or with the feed of the host animal. The present invention further relates to antibiotic BM123.gamma. and certain derivatives thereof, useful for the control of B. bronchiseptica.

Abstract: The invention is novel methods for the control of shipping fever in cattle, comprising administering parenterally to the animals a pharmaceutically effective amount of the antibiotic BM123.gamma., pharmaceutically acceptable salts, and alkyl derivatives thereof.
