Abstract: Disclosed compositions comprise a therapeutic agent and a carrier selected, or processed to have, an acceptable composite flow index, a granular particle size of 18 mesh to 80 mesh, or both, such as processed granular wheat middlings. The composition may also comprise an oil and/or micro tracers. Suitable granular wheat middlings may have a size range of from 18 mesh to 80 mesh, such as 20 mesh to 80 mesh. The composition has improved flowability characteristics, compared to a composition where the carrier, such as processed wheat middlings, are powdered and/or flakey. Certain embodiments concern a composition comprising, consisting essentially of, or consisting of, nicarbazin, granular wheat middlings, soybean oil and micro tracers. The composition may be administered to an animal, for example, to treat or prevent coccidiosis. Also disclosed herein are methods for making and using the composition.

Abstract: A method and apparatus for validating operation of a data volume on a storage medium. A data integrity component is provided which writes data blocks to the volume in a sequence, each data block storing a sequence number and also write status information specifying the sequence numbers of those preceding data blocks in the stream which are still being written to the volume at the time the data block is generated. Data validation is performed by reading back the stored data blocks from the volume and checking that the sequence numbers stored in them match those that should be present based on the sequence numbers stored in the write status information of the last-written data block found on the volume.
