• The dried product is ground so that less than
10 per cent passes a 1 mm screen and more
than 90 per cent passes a 10 mm screen.
9. Inclusion level

animals upto 150kg/t.
• For older animals, it is 50kg/t.
• Fishmeals find their greatest use with simple-
stomached animals.
• For lactating cows, the daily intake of fishmeal
should be limited to not more than 1 kg.

• It contains
• about 10 percent moisture, 55 percent
protein, 6.9 percent fat
• and 25 percent mineral salt particularly 5.4
percent Ca and 3.4 percent P.
• It contains vitamin A, D and richest source of
