We raised cattle when I was growing up (my Dad still does). Cattle have bottom teeth, no uppers (just the upper gum plate). Dairies do use "bolus magnets" to capture metal eaten by cattle so they don't get "hardware disease" (that is a puncture of their digestive system from eating metal). As I was taught in Vocational Agriculture in high school, the magnets stay in the "rumen" which is the first of the 4 parts of the bovine stomach. When I saw that, my first question is how can they tell the cattle are grazing >from a satellite photo? I mean how do you know if they were not all walking to water, or as some people mentioned, in the case of dairy cows, being driven to the dairy barn for milking. Especially if the photos are taken at the same time every day. Now, to the proposed study, we could add a component to study the composition of the soil as well. If there is more Iron content in the soil, do cattle more often or less often align themselves north-south. Also, does that mean they get more iron content from the grass they eat? And what if carrier pidgeons fly overhead, do they concentrate lines of flux and cause more influence? :-)

I have never known a cow to bite a person. In fact they do not have front teeth but just a gum plate. The real danger is by being kicked; hind legs being the most dangerous. No cow/steer is going to let you walk up behind them in a field. If you sneak up on them you are very likely to get both rear hooves to your noggin. And you better hope there is not a bull among the herd or it may likely be the last thing you will ever do. How much does this study pay? No cents… but unlimited male organic fertilizer. ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Gert Gremmen Sent: Wednesday, March 18, 2009 3:45 AM To: [email protected] Subject: RE: Interesting Article Unique field study program Exact today in 2 weeks, there will be a worldwide study organized upon the behavior of cattle exposed to low frequency magnetic field from power overhead lines. The Ministry of Education, Youth and Sport of the Czech Republic http://web.mvcr.cz/archiv2008/english/index.html <http://web.mvcr.cz/archiv2008/english/index.html> and the university of Duisburg–Essen (http://www.uni-duisburg-essen.de/ <http://www.uni-duisburg-essen.de/> ) have invited specialists in EM worldwide to participate in an cattle observation program. They have asked the EM-community to use their networks to address suitable specialists having access to vector field strength measurement equipment. Due to variations in the earth magnetic field versus time, these observations need to take place at exactly 12:00 GMT. (sorry you guys in the US, you will be late for dinner or worse, but you are better off than the Chinese having to stay up all night). The observation program consist of observing any power overhead exposed cattle field and recording the actual nose-tail orientation in grads towards magnetic north of the cattle at that time. Best mean to do that is using a photo camera at considerable height. At the time of observation an indication of the local field strength should be recorded also for each animal recorded individually. For this value to actually represent the field situation a vector measurement need to be made exactly at the position of each specimen. The organizing committee has decided to standardize the exact location to be at the tail of the animal, to prevent the risks of the cow biting the observer.

Some Australians proved that pigeons home using magnetite particles. They exposed the pigeons in a ceramic enclosure with a special cover of organic material to a temperature above the Curie temperature and showed that they lost all sense of direction.
