Are all animal’s dietary requirements equal?......
B. Identify factors effecting nutrition requirements in animals Are all animal’s dietary requirements equal?...... NO!
8
B. Identify factors effecting nutrition requirements in animals
Factors effecting nutritional needs: 1- Maintenance Gives energy for basic needs of keeping an animal alive -Every second an animal is alive it takes energy No loss or gain of weight Known as Basal Maintenance Requirement 50% of animals diet is used for maintenance
9
B. Identify factors effecting nutrition requirements in animals
Factors effecting nutritional needs: 2- Growth Young animals who are not fully grown Extra energy required to grow bones, support organ systems, develop muscle, etc. Need high levels of fats and carbohydrates
10
3- Gestation & Lactation
B. Identify factors effecting nutrition requirements in animals Factors effecting nutritional needs: 3- Gestation & Lactation (Gestation = Pregnancy, Lactation= milk production) Nutrition deficiencies are the most common cause of reproductive failures Pregnancy requires higher levels of nutrition and energy intake (Especially at the end of pregnancy when the fetus is growing rapidly) Milk production requires even more energy (Especially calcium, phosphorus, protein)
11
B. Identify factors effecting nutrition requirements in animals
Factors effecting nutritional needs: 4- Work Animals used for heavy work, require more energy For Example: hunting dogs, draft horses, race horses, etc.

Pearson Square A 1400-pound cow in the second trimester of pregnancy needs 6.9% protein. She is given 23.3 lbs of feed most of which is grass hay at 5.5% protein. How many pounds of soybean meal (49.6% protein) should the cow be given to make sure she receives 6.9% protein?
47
Sample Problem Formulate 600 lbs of a 26% CP ration using CSM (54% CP) and Barley (8% CP).
48
What’s Being Asked? You have 2 different feeds on hand, each containing a certain amount of protein. But for your purposes, neither will suffice. You need to mix them to make a new feed of a specific amount protein. And you need to make 600 lbs of the new feed.
49
Solving…..using a Pearson Square
These types of problems are easy….but you have to use the Pearson Square. 1st set up the square (this will be the same every time:
50
2nd, label the square: Feed #1 goes here Feed #1 also goes here
With its %CP The %CP you want goes here Feed #2 goes here Feed #2 also goes here With its %CP
51
This is what it should look like:
CSM CSM 54% 26% Barley 8% Barley
52
3rd, some simple subtraction…one feed at a time.
Subtract going diagonally: #1. CSM (54) – 26 = 28% Barley: CSM 54% CSM 26% 28 parts Barley Barley 8%
53
4th, do the same calculation for the second feed.
Subtract on the other diagonal: Barley (8%) – 26 = -18 % CSM. But just use the absolute value….ignore the negative sign: 18 parts CSM CSM 54% 26% Barley 8% 28 parts Barley
54
5th, add up total parts CSM and Barley for the new feed:
+ 26% Barley 8% Barley 28% 46 total ( = 46)
55
Wait….What’s going on? We just calculated what percent of our new ration will be CSM and Barley: of the total amount of new feed, it will be 28 parts Barley and 18 parts CSM. Now we have to determine how many pounds of each this correlates to. Once we know that, we can mix our feeds together.
56
So from the square, we know that in our final feed we need:
28 parts Barley 18 parts CSM We also know from the problem that we need 600 lbs of the new feed. This is the easy part!
57
Just convert parts to %:
Remember the formula for percentage: Part/whole x 100 = %part Barley: 28 parts / 46 total parts x 100 = 60.87% CSM: 18 parts / 46 total parts x 100 = %
58
Then convert % to lbs: Now we know what % of final feed will be barley and CSM, and from the problem, we know we want 600 total lbs of feed. We just need to figure out how many lbs of each this means! Barley: 600 lb x = lbs! CSM: 600 lb x = lbs! This is your answer! You need to mix lbs barley and lbs CSM to make your mix!

List all 6 essential nutrients that an animal should have
Bell Quiz: List all 6 essential nutrients that an animal should have Name 3 factors that effect an animal’s nutrition needs What is the definition of a roughage? Give an example. What is the definition of a concentrate? Give an example.
60
What is the definition of “free feeding?”
Bell Quiz: What is the definition of “free feeding?” What is the definition of “scheduled feeding?” Name a pro and a con for each method of feeding Compare and contrast roughages and concentrates
61
Bell Quiz: List each species of animal you have ever owned and tell me what you feed it and how much it gets daily
62
Let’s Check the Answer Barley: we determined lbs needed; and from the problem we know that our barley is 8% CP; x 0.08 = lb CP CSM: we determined lbs needed; from the problem we know CSM is 54% CP; x 0.54 = These two answers should add to give the percent CP we were looking for: = 156 156 lb CP / 600 total lb feed x 100 = 26% CP
63
Ready for another one? A zelephant is on a feed that requires a ration containing 55% TDN. The TDN of two feeds, alfalfa hay and corn, are 89% and 22%, respectively. Determine the amounts of each feed necessary (in units/300 lbs) to meet the TDN requirement of the zelephant.
64
Answer Alfalfa Hay 89% 33 parts Alfalfa Hay Corn 22% 34 parts Corn 55%
67 total parts Alfalfa: 33 parts / 67 total x 100 = 49.25%; 300 lbs x = lbs Corn: 34 parts / 67 total x 100 = 50.75%; 300 lbs x = lbs Check the answer: alfalfa: lbs x .89 TDN = lb TDN corn: lbs x .22 TDN = lb TDN = total TDN / 300 lb feed x 100 = 55% TDN

Keep clean fresh water available at all times. FOR RUMINANTS ONLY Complete Horse IFA COMPLETE HORSE PELLETS are large pellets that are formulated to be the sole and complete feed for most horses. No additional hay is required. IFA COMPLETE HORSE PELLETS are easily digested by horses. Feed approximately 1- 1 ½ lbs / 100 lbs of body weight/day. (A horse weighing 1,000 lbs should be fed from 10 – 15 lbs of IFA COMPLETE HORSE PELLETS/day). Split the total ration amount into two equal feedings. The amount of feed should be varied according to the activity level of the horse. IFA COMPLETE HORSE PELLETS are balanced and contain all the nutrients that a horse requires.
