Question restatement: Which of the following cattle breeds is/are always naturally polled? (Select all that apply) Options: Brahman, Angus, Hereford, Limousin, Droughtmaster, Wagyu

Option 1 – Brahman: This breed is commonly horned, and while some individuals or lines may be dehorned or carry polled genetics, it is not universally naturally polled. The general breed standard does not guarantee hornlessness in all individuals, so this is not a universally polled breed.

Option 2 – Angus: Angus cattle are widely recognized for being naturally polled (hornless) in their standard populations. This horn status is a characteristic that holds across typical purebred Angus lines, making this option a valid choice for breeds that are always naturally polled.

Option 3 – Hereford: Historically, Herefords have horns in many populations, though there are polled lines. However, they are not universally naturally polled across the entire breed, so this cannot be considered always naturally polled.

Option 4 – Limousin: Limousin cattle commonly have horns; polled genetics exist but are not the universal standard of the breed. Therefore, they are not always naturally polled.

Option 5 – Droughtmaster: This breed is generally horned in many populations, and while polled individuals can occur, it is not a defining or universal trait of the breed. Hence, not always naturally polled.

Option 6 – Wagyu: Wagyu cattle can be horned or polled depending on line and management, but they are not universally naturally polled across the breed. Thus, this option does not meet the criterion of always naturally polled.

Summary: Among the listed breeds, only Angus is reliably naturally polled in standard populations. The other breeds may have polled individuals or lines but are not universally hornless, which is why they are not considered always naturally polled.
