  1. A BRIEF INTRODUCTION TO THEWUFFDAPROGRAM LECTURE AND TURORIAL FOR CHAPTER 23 FEED FORMULATION : SPECIFYING PROPORTIONS POULTRY NUTRITION FUNDAMENTALS

  2. Chapter 23 Section I. INTRODUCTION

  3. FORMULATION PROGRAM ADVANCED CAPABILITIES • RATIOS BETWEEN NUTRIENTS & RATIOS BETWEEN INGREDIENTS • HOW TO SPECIFY AMINO ACIDS AS A PERCENTAGE OF PROTEIN, THE ENERGY TO PROTEIN RATIO, OR THE CALCIUM TO PHOSPHORUS RATIO? • HOW TO SPECIFY INGREDIENT RATIOS, LIKE OYSTER SHELL TO LIMESTONE, OR CONCENTRATE TO FORAGE?

  4. Chapter 23 Section I I. PROPORTIONS BETWEEN NUTRIENT MINIMUMS

  5. OPEN THE WUFFDA ENGLISH.XLS WORKBOOK OR THE LAST WORKBOOK FROM CHAPTER 22

  6. ADD FISH MEAL, FEATHER MEAL, OYSTER SHELL, METHIONINE, THREONINE AND TRYPTOPHAN TO THE LAST PROBLEM IN CHAPTER 22.

  7. SPECIFY AMINO ACIDS AS A % OF DIET

  8. REMEMBER TO ENTER MAXIMUMS SO THE PROGRAM DOESN’T ASSUME ZERO’S

  9. SOLVE, & PRINT YOUR ANSWERS

  10. ENERGY, PROTEIN, CA, P, LYS AND TSAA ARE ALL AT THEIR REQUIREMENT LEVELS

  11. SPECIFY AMINO ACIDS AS A % PROTEIN

  12. SOLVE, & PRINT YOUR ANSWERS

  13. NUTRIENT LEVELS APPEAR THE SAME, INGREDIENT LEVELS ARE CHANGED SLIGHTLY

  14. CHANGE THE PROTEIN MINIMUM TO 20% WITHOUT CHANGING AMINO ACID REQUIREMENTS

  15. SOLVE, & PRINT YOUR ANSWERS

  16. AMINO ACID REQUIREMENTS AND AMOUNTS SUPPLIED SHOULD CHANGE AUTOMATICALLY WITH PROTEIN LEVEL

  17. Chapter 23 Section III. EXACT PROPORTIONS BETWEEN NUTRIENTS

  18. TYPE IN: “Ca:P” IN CELL P2, “2” IN CELL P3 (FOR A 2:1 RATIO), “=I5-($P$3*J5)” IN CELL P5. COPY CELL P5 DOWN COLUMN P

  19. INGREDIENTS WITH MORE CA THAN P SHOULD HAVE A POSITIVE NUMBER, LESS A NEGATIVE NUMBER IN COLUMN P

  20. SET THE MINIMUM AND MAXIMUM FOR Ca:P BOTH TO 0 (ZERO), AND REMOVE THE MINIMUM ON AVAIL. PHOS.

  21. SOLVE, & PRINT YOUR ANSWERS

  22. AVAIL. PHOS. SHOULD STILL BE AT 0.45 % DESPITE THERE BEING NO REQUIREMENT SPECIFIED EXCEPT ON THE INGREDIENTS WORKSHEET

  23. CHANGE THE CALCIUM MINIMUM, SOLVE THE PROBLEM AND OBSERVE WHAT HAPPENS TO THE AVAIL. PHOS. LEVEL IN THE SOLUTION

  24. Ca AND AVAIL. PHOS. SHOULD REMAIN IN A 2:1 RATIO

  25. Chapter 23 Section IV. SPECIFYING INGREDIENT CLASS MINIMUMS

  26. ADD A COLUMN FOR “ANIMAL PRODUCTS” GIVE EACH ONE A VALUE OF 100 (EXCEPT POULTRY GREASE AND OYSTER SHELL)

  27. RESTRICT THE USE OF FEATHER MEAL TO 2 % OF THE FEED

  28. RESTRICT THE USE OF ANIMAL PRODUCTS TO 3 % OF THE FEED

  29. SOLVE, & PRINT YOUR ANSWERS

  30. SOLVE THE PROBLEM WITH 3, 5 AND 7 % ANIMAL PRODUCTS AND NOTE THE INFLUENCE ON FORMULA COST

  31. Chapter 23 Section IV. SPECIFYING INGREDIENT CLASS MINIMUMS

  32. CHANGE THE NUTRIENT REQUIREMENTS TO A LAYER FEED

  33. SOLVE, & PRINT YOUR ANSWERS

  34. THE SOLUTION HAS ALL LIMESTONE & NO OYSTER SHELL BASED ON COST

  35. ADD COLUMNS FOR PULVERIZED AND COURSE Ca SOURCES ADD “=R5-($T$3*S5)” IN CELL T5. COPY CELL T5 DOWN COLUMN T

  36. SOLVE, & PRINT YOUR ANSWERS

  37. THE SOLUTION HAS HALF LIMESTONE & HALF OYSTER SHELL

  38. FEED FORMULATION : PROPORTIONS PROGRAMMING • ANSWER THE QUESTIONS ON PAGE 23-7 • TURN IN YOUR • PRINTOUTS • ANSWERS ON PAGE 23-7
