# How does Pearson square method calculate feed formulation?

## How does Pearson square method calculate feed formulation?

To use Pearson’s Square: Subtract the nutrient requirement (middle of square) from the nutrient concentration (on left of square) in the feed across the diagonal (top left – middle = bottom right; bottom left – middle = top right). Repeat this for both feeds.

How do you calculate protein feed?

The crude protein percentage (CP%) is calculated by multiplying the nitrogen (N) percent of feed by 6.25. This is because on average protein contains around 16% Nitrogen (1/0.16 = 6.25). Urea has 287% crude protein: 46% nitrogen multiplied by 6.25 which equals 287% protein.

### How do you calculate feed ration for cattle?

1. % feed 1 x pounds of ration = total pounds needed for ration.
2. % feed 2 x pounds of ration = total pounds needed for ration.

How do you calculate crude protein in poultry feed?

To get the total crude protein percentage of all these ingredients in a 70kg bag of feed, the farmer should take this crude protein content of the combined ingredients, divide by 70kg and multiply by 100, thus — 13.30 ÷70 ×100 = 19%; this shows that the crude protein content of the above feed formulation is 19%, which …

#### How do you solve feed formulation?

Place the two grains and their respective crude protein contents on the left hand corners of the square. Note – disregard the negative or positive value of the numbers. Calculate the percentage of each grain. Add the two portion figures to give the total and calculate each feed as a percentage.

How is fish feed formulation calculated?

To make the 27 percent crude protein carp feed, we must mix 17/35.8 of rice bran with 18.8/35.8 soybean meal. So to make 100 kg of this feed we must mix 47.5 kg of rich bran with 52.5 kg of soybean meal….2. BALANCING CRUDE PROTEIN LEVEL.

Rice bran 27.265 kg
Corn 27.265 kg
Soybean meal 22.735 kg
Shrimp meal 22.735 kg

## How is feed formulation calculated?

How do you calculate total feed cost?

Determine the cost per pound of nutrient. Divide the per-ton price of feed by the pounds of actual nutrient contained in a ton. Example: (\$340/ton)/360 lb CP in a ton = \$ 0.94/ lb CP; Use this figure in your price comparisons for different feeds.

### What is Pearson square method?

The ‘Pearson Square’ is a tool that can be used to calculate the portion of two feeds needed to meet protein or energy requirements of an animal. For this tool to work, one of the feeds used must be higher in ME or CP than the desired level and the other feed must be below the desired level.

How much protein is in 100g broiler chicken?

This is equal to 31 grams of protein per 100 grams (3). A chicken breast also has 284 calories, or 165 calories per 100 grams. 80% of the calories comes from protein, while 20% comes from fat (3).

#### What is the Pearson Square calculation and how does it work?

How do you calculate feed formula?

By summing those parts and dividing by the total, you can determine the percent of the ration that each ingredient should represent in order to provide a specific nutrient level….Quick Facts…

88.57 lb corn x 10.0% CP = 8.86
11.43 lb SBM x 45.0% CP = 5.14
100.00 lb mixture contains = 14.00 lb CP, or 14 percent.
