Influences of EM on quality of grass/hay for milk-production


Mr. Herbert Plangger and his family from Walchsee/Tyrol, Austria. Owner of a daily, producing cheese trademarked as “Bergkase”, “Bio-Senner”, “Emmentaler” etc. by using only unpasteurized milk.

120 farmers deliver between 50,000 and 60,000 litres of milk each a year. 75% of these suppliers are organic farmers. In summertimes milk comes from cows living on alpine pastures up to 1,800 m above sea-level. Right there a variety of short grass and herbs is growing.

Some farmers have installed special hay-drying –machines. There, in a closed system, material is dried in a very carefully way. The effect: hay of extraordinary quality.

How EM is in Use
  • 120 farmers strew a special stonemeal -treated with EM - on their meadows
  • Some twenty farmers use EM in addition as feed additive for manure treatment and for cleaning
  • EM is used for cleaning process in the dairy
Let’s find out, whether it’s possible to increase
- quantity and
- quality of grass / hay by
- strewing stonemeal with EM
- and drying hay carefully

Materials and Methods
An organic farmer, the Brunner family, living in Erl/Tyrol (800 m above sea level; 1,400 – 1,450 mm rainfall a year), is using now for two years:
- Stonemeal treated with EM
- EM-extended put to the manure
- some EM-extended as feed additive in winter; in summer livestock is on the alp
- hay-drying-machine with a drying-capacity of 21 of water/min.

  • 25% more hay, second and third cut of high quality
  • approx. 1,000 liter / cow / year more milk
  • Save of additional diet – only some cereals are needed
  • Livestock is more vital and healthier
  • very good quality of milk
Hay was examined by Prof. Dr. A. Haiger, University of Bodenkultur, Vienna, in spring 1999. These were the results:

1 kg fresh material
1 kg dry mass
Dry mass
g 915 1000
Crude fiber
g 200 218
Raw protein
g 148 160
Energy mj 5.60 NEL
5.12 NEL

  • The result of the examined hay are much better than the European average
  • “...compared with figures of average material it is an excellent hay, which is found only very seldom in this days”, the University confirmed
  • It’s difficult to measure what EM-extended is participating in this success
  • It seems to be evident that treatment with EM and the careful drying method of roughage lead to very encouraging results
