Answer

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that many countries have banned the use of antibiotics in cattle feed. This is a factual statement reflecting a trend in agricultural practices aimed at addressing public health concerns.

2. **Understanding the Reason (R)**:
- The reason provided states that dairymen give antibiotics in the feed to cattle, which creates breeding grounds for antibiotic-resistant bacteria. This highlights the consequence of using antibiotics in livestock, leading to the development of resistance.

3. **Analyzing the Link between A and R**:
- The link between the assertion and the reason is that the use of antibiotics in cattle feed leads to the development of antibiotic-resistant bacteria, which poses a risk to human health. This is a significant reason why many countries have chosen to ban antibiotics in cattle feed.

4. **Evaluating the Truth of Both Statements**:
- Both the assertion and the reason are true. The assertion is a reflection of current regulatory practices, while the reason explains the rationale behind these practices. The use of antibiotics in cattle can indeed lead to antibiotic resistance, which is a growing concern in public health.

5. **Conclusion**:
- Since both the assertion and the reason are true, and the reason provides a valid explanation for the assertion, we conclude that the correct answer is that both statements are true and the reason is an explanation for the assertion.

### Final Answer:
Both the assertion and the reason are true, and the reason is the correct explanation for the assertion.
