Estrange places to find a chromatographer, Part I: Cattle farm

During undergraduate studies I worked for 4 years in the lab where most of students came to do the chromatography part of their work. In that time, I met some Veterinary students ( it seems that in Brazil you can have a bachelorship in veterinary , but in other places as USA, Veterinary is a Ph.D tittle). Well, among the studies they carried out , on was really interesting: In animal nutrition studies they monitor the amount of acids created in rumen depending on diet. Well, how they monitor that? With Gas Chromatography of course.
However in, 2006 an old mate from collegue start to look for me and asking stuffs about the Nukol columns, which is specific for free acids. My surprise was that he was doing GC analysis (as Chemist) in a big cattle farm in west part of Brazil, not that I couldn’t imagine farms operating with some technological improvement, I just could imagine a chromatograph beside the cow's enclosure!
