Sustainable and organic farming practices are becoming more and more common these days. With this, farmers are converting their farms into sustainable farming units where methods and techniques are used to ensure environmental protection while yielding organic products. One of the bizarre techniques being used, however, in US organic farms is making a big hole in the cow stomach to observe their digestion process physically. Although the practice looks unpleasant and unnatural but scientists are of the opinion that this will help improve the lifespan of the cow. The cows seem oblivious of the holes and do not look distressed at all because of which the technique is very successful so far.
Known as a fistula, the hole is used by the scientists to reach inside the stomach to check the digestion process.
The cows can be given medicine directly from the fistula if they get ill.
