[more ▼] Embryo transfer is a globally executed technique which, when properly done, has both economic and sanitary advantages. International guidelines are available to prevent infection of the embryo with pathogens, both originating from the donor animals as from the environment. This manuscript describes the bacteria, viruses, protozoa, fungi and prions that are of major concern in the context of embryo transfer in cattle. In addition, the actual scientific knowledge on these pathogens is evaluated in terms of the current international and national guidelines and legislation.

[more ▼] Pharmacokinetic parameters of sulfamethazine (SMZ) administered intravenously or orally either as an aqueous solution or as a lipid matrix formulation, were determined in young lambs. The value of the rate constant for elimination (ke) for the intravenous solution was 0.18 h−1 compared to 0.10 h−1 for the oral aqueous solution. The absolute bioavailability of the oral solution was about 75%. A lipid matrix containing SMZ and a high density excipient is able to be retained in the reticulo-rumen and to produce a sustained release of the drug for at least 100 h provided that the mechanical strength of the bolus is sufficient. The pharmacokinetic data obtained with the lipid matrix show a release profile with two pulses due to both diffusion and erosion mechanisms. Plasma levels are maintained above the MIC of SMZ during 100 h with an absolute bioavailability of 51.7% [less ▲] Detailed reference viewed: 10 (1 ULg) |
