Development of a new welfare assessment protocol for practical application in long-term dog shelters.

In many European shelters, dogs may spend many years confined. A poor environment and inappropriate management may lead to a low quality of life. The absence of harmonised European regulatory frameworks defining the minimum requirements for shelter facilities makes the definition of welfare standards for kennelled dogs challenging.

Use of an anti-GnRF vaccine to suppress estrus in crossbred Iberian female pigs.

Antibodies against GnRF elicited by vaccination with Improvac are expected to have the same effects on the gonads of female pigs as those observed in males and thus suppress estrus. The objective of this study was to evaluate whether a 3- or a 4-dose regimen of Improvac was effective in inducing and maintaining suppression of estrus in intact Iberian female pigs through 14 months of age. Sixty 18-week-old gilts were randomly assigned to one of the following three treatment groups: control (PBS injected), V3 (3-dose Improvac regimen), and V4 (4-dose Improvac regimen).

HPLC quantification of perphenazine in sheep plasma: application to a pharmacokinetic study.

A high performance liquid chromatographic (HPLC) method for the determination of perphenazine (PPZ) in sheep plasma was developed and validated. The separation was achieved using a 5 microm C18 column (125 mm x 4 mm) with a mobile phase composed of acetonitrile and an aqueous solution of H(3)PO(4) and TBA (inverse gradient). The flow rate was 1.
