Feed Formulation
Feed Formulation Mathematical calculation to prepare a balanced ration Points to be considered Requirement of nutrients Nutrient composition Maximum effective/safe levels of inclusion Availability and cost
Requirement of nutrients
Requirement of nutrients Metabolizable energy Protein and amino acids (lysine, methionine, methionine + cysteine, threonine) Calcium, available P Electrolyte balance (sodium, chlorine) Trace min. Zn, Mn, Fe, Cu, Se Vitamins – A, D3, E, riboflavin etc.
Methods of feed formulation
Methods of feed formulation Algebric equation used when two mixtures are to be combined for arriving at required nutrient concentration – cereal and protein concentrates Pearson square Simple procedure originally devised to blend milk products to a known fat percentage, and can be used for diet formulation too

Hit and trial method
Hit and trial method Traditional way of feed formulation and still widely used by professionals Amount of feed ingredients is changed so as to arrive at required nutrient levels in the feed For this, the ingredients are arbitrarily altered and the nutrient concentration is calculated, which is continued till the desired nutrient level is achieved. Computer applications – MS Excel Ex.2
Least cost formulation
Least cost formulation Is a feed formula that is both nutritionally-complete (within limits) and with a minimum ingredient cost (within limits) Linear-programming Numerous computer software – Ecomix, Winfeed, Myfeed, FeedMu, Feedsoft, Autofeed, Optimix etc.
Conclusions
Conclusions Understand the nutritional needs of bird Intensive system – balanced diet with low cost materials Reduce cost of broiler feed and feeding Nutrients, Formulation, Precise Feeding Control environments to reduce stress & diseases Recommendations: 1.Adopt new technology 2.Benchmark to the leading broiler 3.Always improve Efficiency
Conclusions
Conclusions The nutrient requirements have to be regularly updated for precision and economical feeding The additive effects of the additive’s should be quantified in terms of nutrient values to help in formulation The efficiency of the digestion is being constantly targeted and upgraded The metabolism which is the major waster should be targeted hence future works should be at the cellular level
