The use of a cannula in a cannulated cow allows access to one of the
four stomachs of the cow, the rumen. This access to the rumen can allow
for a forage quality analysis. This analysis can help producers to
identify the nutritional needs of a cow, identify the optimal and most
cost-effective Total Mix Ration (TMR), research the effects of chosen
food on the cow's health and provide the farmer with knowledge about his
cattle. It actually helps the cows they say. However,
... 'knowledge is power'. I did my RESAERCH so not to just judge
from pictures alone. My first question was 'why are they doing this?' so
i looked for answers and from what I just read this is a legitimate
treatment for cows or sheep with a specific disorder appearently called
'bloat'. I got this site from a wikipedia-article about cannulae: http://www.merckvetmanual.com/mvm/index.jsp?cfile=htm/bc/21705.htm
