Praxis Agriculture (5701) Practice Exam

In a balanced ration, the nutrient allowance should be no more than what percent of the animal's requirement?

2% 3% 5% 10%

Correct Answer:

Explanation:

When formulating a balanced ration, you plan to meet the animal’s needs but must account for real-world variability. Small safety margins are added as a nutrient allowance to cover differences in intake, digestion, feed composition, and measurement error. That margin should be kept tiny to avoid pushing the animal into excess. The best answer is that the allowance should not exceed 3% of the animal’s requirement, providing a protective cushion without overfeeding. A margin of 2% might be too tight to cover variability, 5% could lead to unnecessary oversupply and higher costs, and 10% is unnecessarily large and risky for overconsumption. Keep the allowance around 3% to balance safety and efficiency.
