A recent study has revealed that cow flatulence is to a great extent responsible for global warming and the green house effect.

Grain based diets for dairy cows are getting more interest as fodder and land are getting more expensive. The Australian dairy industry has therefore launched a research project to find out whether feeding cows grain will increase the amount of milk they produce.

Due to increasing raw material cost for animal feed, the search goes on to find cheap alternative feedstuffs. Duckweed, with its high quality protein content and balanced amino acid profile, could be one of these alternatives.
