Recombinant bovine somatotropin misuse in cattle

Results obtained showed the relevance of the two approaches. The Western blot one, carried out in this work on real biological blood samples collected on treated animals, would fit as a rapid and rather sensitive screening method, which can further more be achieved more over a long period after the administration of recombinant hormone. The second method, which consisted in a proteomic approach, dealt with the development of a confirmatory technique. Results on spiked milk samples were very promising and showed the need of further developments in this way.
