1. A BRIEF INTRODUCTION TO THE WUFFDA PROGRAM
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. PROPORTIONS BETWEEN NUTRIENT MINIMUMS
Chapter 23
Section I I.
PROPORTIONS BETWEEN NUTRIENT MINIMUMS

5. OPEN THE WUFFDA ENGLISH
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. EXACT PROPORTIONS BETWEEN NUTRIENTS
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
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. SPECIFYING INGREDIENT CLASS MINIMUMS
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. SPECIFYING INGREDIENT CLASS MINIMUMS
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
