Which of the following is a significant benefit of dehorning cattle?

Dehorning cattle is primarily associated with improved human safety, which is a major benefit of this practice. Cattle with horns can pose a risk to handlers, equipment, and other animals due to their ability to use horns defensively. By removing horns through dehorning, the potential for injurious behavior decreases, creating a safer environment for both the animals and the humans involved in their care.

This practice directly contributes to a safer working condition on farms and ranches, especially in environments where animals are housed closely or when they are being handled for veterinary care or transportation. While the other options may touch on various aspects of cattle management, they do not directly relate to the safety considerations that make dehorning a significant practice. For instance, while enhanced feeding efficiency and increased weight may be influenced by other factors such as nutrition and genetics, they are not direct results of dehorning. Similarly, disease resistance is more closely tied to health management practices rather than the presence or absence of horns. Overall, the emphasis on human safety clearly positions this benefit as the most significant in the context of dehorning.
