Agricultural Researchers Are Interested in the Effect of Production Efficiency

question 102

Multiple Choice

Agricultural researchers are interested in the effect of production efficiency on economic impacts, sustainability, and production of greenhouse gases by cattle.Two groups of cattle were fed different diets.One group was fed exclusively on grass.The other was fed an energy-rich diet that included grain supplements.How would the two diets most likely affect production efficiency of the cattle?

• A) Grass-fed cattle would have a higher production efficiency.
• B) Grain-fed cattle would have a higher production efficiency.
• C) Production efficiencies would always be equal under the two diets.
• D) As long as both groups ate the same amount of food, production efficiencies would be equal.
• E) As long as grain-fed cattle ate more food than grass-fed cattle, production efficiencies would be equal.
