FFA Poultry Judging Practice Test

To determine how many pounds of corn and concentrate are needed to create a feed that is 100 pounds and contains 18.0% crude protein, it is important to understand the protein contributions from both ingredients.

Corn typically contains a lower protein content compared to concentrated feed ingredients, such as soybean meal or other protein supplements. Generally, corn might provide around 8% protein, while the concentrate can offer a significantly higher protein percentage, often around 44% or more.

In this scenario, when formulating a feed with an overall target of 18% protein, the formula involves calculating how much of each ingredient is needed to achieve that average based on their respective protein contributions.

Starting with 100 pounds of final feed, one must ensure that the combined protein from the corn and the concentrate meets the required protein level. If the combination yields the correct amount of crude protein, then the specified quantities will support the necessity for an 18% protein content.

Using the correct mixture (as stated in choice B with 72 pounds of corn and 28 pounds of concentrate) effectively balances the protein content, providing enough volume of both corn (which contributes less protein) while integrating the concentrate to meet the target percentage. This particular combination successfully reaches the desired
