A BRIEF INTRODUCTION TO THE WUFFDA PROGRAM

• LECTURE AND TURORIAL
• FOR CHAPTER 23

FEED FORMULATION SPECIFYING PROPORTIONS
POULTRY NUTRITION FUNDAMENTALS
2
Section I.
Chapter 23

• 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
Section I I.
Chapter 23

• 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 DOESNT
ASSUME ZEROS
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
Section III.
Chapter 23

• EXACT PROPORTIONS BETWEEN NUTRIENTS

18
TYPE IN CaP IN CELL P2, 2 IN CELL P3 (FOR A
21 RATIO), I5-(P3J5) 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 CaP 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 21 RATIO
25
Section IV.
Chapter 23

• 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
Section IV.
Chapter 23

• 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-(T3S5) IN CELL T5. COPY CELL T5 DOWN
COLUMN T
36
SOLVE, PRINT YOUR ANSWERS
37
THE SOLUTION HAS HALF LIMESTONE HALF OYSTER
SHELL
