a vitamin- and protein-rich feed made from artificially dried grasses. Grass meal is produced at kolkhozes and sovkhozes. It consists of cultivated perennial and annual grasses and meadow grasses having a high legume content. Herbaceous legumes are mowed in the budding stage; cereals are mowed at the onset of heading. The production of grass meal involves mowing, chopping, and drying the grass; grinding the chopped material; granulating the meal; and packaging. The chopped grass is dried and ground in special production units (AVM-0.65, SB-1.5) and granulated by granulation units. Antioxidants (for example, santoquin) are added to the meal to help preserve the carotene. The meal is packaged in kraft bags and stored in a dark, dry place.
One kilogram of high-quality grass meal contains 0.7–0.8 of a feed unit, 140–150 g of digestible protein, and 200–300 mg of carotene. The meal also contains vitamin E, vitamin K, and the B-complex vitamins. The protein is rich in essential amino acids. Grass meal is given to all species of farm animals as a protein and vitamin supplement. It is most often used in poultry raising. Grass meal is included in mixed feeds.
Grass meal production in the USSR was 82,000 tons in 1965, 820,000 tons in 1970, and more than 4 million tons in 1975.
