Efficiency of currently used anthelmintics in bovine practice
In selecting an anthelmintic the veterinarian must concern himself with the several attributes within which the most desirable chemical can be defined. These attributes are the therapeutic index, ease of administration, presence or absence of residues, efficiency, and cost. It is quite obvious that no particular anthelmintic is superior in all characteristics, since if one were it would soon be the only marketable product. The primary purpose of this paper is to examine one of these characteristics, namely efficiency, in relation to the currently available anthelmintics for cattle.
