Here’s how you can do it: Problem: Express 24 × 40 using the distributive property. Step-by-Step Solution: Final Answer: 24×40=96024 \times 40 = 96024×40=960 […]

Calculate the crude protein content of a feed mixture containing 91 kg of corn (8.0% CP) and 9 kg of urea (45% N). 2. Corrected_text: Calculate the nitrogen-free extract (NFE) in a feed which contains 11% water, 6% ash, 30% crude protein, 8% ether extract, and 5% crude fiber. 3. Corrected_text: If 2,000 IU of

In animal feeds, crude protein is calculated as nitrogen multiplied by 6.25 (the assumption is that proteins of typical animal feeds contain 16% nitrogen on average). As the feed analysis report shows a feedstuff to contain 2.2% nitrogen and 86% dry matter (as fed basis), calculate the percent of crude protein (% CP). Utilize the
