|  Blood as a secondary
product from slaughter of domestic animals for the needs of the meat industry in Macedonia
is waste. The treatment of such substances seriously threatens the environment, on the
other hand, hundreds of tons of potential protein food is wasted. In average in the
Republic of Macedonia, about 1.5 million sheep are slaughtered, 200,000 pigs and 75,000
cows. So, in average, the total quantity of blood residuum??? in Macedonia is about 2,800
tons per year. Due to the fact that proteins partake with 20% in the contents of blood in
domestic animals, in average about 600 tons of pure proteins are wasted. Solution: this
substance needs to be processed and used as fodder. There are different means of
processing this product depending on the product we need. The effects are more fold: large
resources used in the maintainance of waste water treatment systems in industrial
slaghterhouses are saved, the ground waters are protected from pollution, and additional
financial effects is accomplished.
