  1. 1. Feed Formulation Strategies And Methods Submitted by Amit kumar Jana M.F.Sc. 4th sem. Dept. of Zoology And Applied Aquaculture
  2. 2. Synopsis:- • Introduction • Feed formulation strategies 1. Diet selection 2. Waste estimation 3. Ration allowance 4. Feeding strategies • Methods • (a) Pearson’s Square Method. • (b)Trial and Error Method.
  3. 3. Introduction Fish food consist of natural food and artificial feed. Single feed ingredients may be fed to fish to supplement available natural food in a pond. However ,combining ingredients may make better quality supplemental feed. Fish would grow well on a feed containing 20 to 30% crude protein ,of which 7 to 10% of the protein is from animal source. When natural food is abundant and fish are stocked at low densities,a 20 to 25% protein content is suitable. A 30% or more crude protein content is more suitable for fish are stoked at high densities.

  5. 5. Pearson’s Square Method. • The simplest method to calculate the ration, It can be used for 2 and more ingredients. • It can be balanced only one nutrient (make your choice for crude protein or crude fat). • Always keep in mind the nutrient value of the ingredients. • if we have more than 2 ingredients.
  6. 6. Pearson Square • We have a solution… • Reach 40% crude protein using fish meal, corn gluten meal, wheat meal and soybean meal. • The crude protein % of ingredients: • Fish meal: 65% • Corn gluten meal: 38% • Soybean meal: 42% • Wheat meal: 17%
  7. 7. Pearson Square • The solution is to make two groups into the ingredients. • First group will be consisted of fish meal and soybean meal. • Second group will be consisted of corn gluten meal and wheat meal.
  8. 8. calculation • First group average: (65 + 42) / 2 = 53,5 • Second group average: (38 + 17) / 2 = 27,5 • Group one 53,5 12,5 40 • Group two 27,5 + 13,5 • -------- 26
  9. 9. calculation • % of group one: (100 x 12,5) / 26 = 48,07 • % of group two: (100 x 13,5) / 26 = 51,92 • 1st group’s ingredients %: 48,07 / 2 = 24,035 • 2nd group’s ingredients %: 51,92 / 2 = 25,96
  10. 10. Calculation 40% crude Protein • % of Fish meal: 65 x 24,35% = 15,83 • % of Soybean meal: 42 x 24,35% = 10,23 • % of Corn gluten meal: 38 x 25,96% = 9,86 • % of Wheat meal: 17 x 25,96% = 4,41 • Total = 40,33
  11. 11. Trial and Error Method To choose a combination of ingredients that will provide a feed containing between 25 to 30% crude protein. Ingredient Amount of ingredient (Kg) %of Protein Rice Bran 40 9.9 Brewer Waste 20 22.8 Soyabean Meal 28 46.2 Fish Meal 12 57.7 Total 100
  12. 12. Calculation • To calculate the required % CP in feed. Rice bran- 40*9.9/100=3.96(4.0) Brewer waste -20*22.8/100=4.56 Soyabean meal-28*46.2/100=12.93 Fish meal -12*57.7/100=6.92 Total Crude Protein=28.4
  13. 13. Calculation This feed would contain 28.4kg of crude protein if 100kg of the listed ingredients were combined as indicated.This would make a feed containing approximately 28% crude protein by weight scince.28.4kg*100kg/100=28.4% Protein containt.
  14. 14. Conclusion • Natural food organisms (Phytoplankton , zooplankton,insects,crustaceans,copepods and molluscs) in water will provide essential nutrients but in the conditions (in sufficient of natural foods, high stocking density, promote faster growth) use artificial food.In the use of supplementary feed based on strategies.
