Meanwhile, he took a visit to Ba Vi Cow and Pasture Research Centre to learn experiences, his cow herd totally has 10 cows till now. Through accounting expenses and interest, he always gets over 1 million/cow/month.
In spite of having Biogas vault to treat wastes, however, a large amount of wastes, surrounding environment might be influenced. Thus, Mr. Hoa decided to raise worms to treat these wastes, the systems began with 2x2 m2 at first time, later expanding to 200 m2.
“It is very simple to build worm raising facility, with a higher bit than the ground is filled with water, this can be used with plastic tray or plastic tub in order to drain easier, surrounding is covered to keep away from sun, rain and insects.”
