Final answer:
To ensure female cows become productive in a cattle-breeding business, Samuel should breed them annually, provide a varied diet, and separate them from the herd.
Step-by-step explanation:
To ensure that female cows become a productive part of Samuel's cattle-breeding business, he should do the following:
- Breed them at least once a year: This will allow the cows to reproduce and contribute to the growth of the herd.
- Provide a varied diet: A balanced and nutritious diet will support the cows' overall health and productivity.
- Separate them from the herd: Separating the female cows will help Samuel closely monitor their health, behavior, and breeding process.
Minimizing water intake is not recommended as cows require adequate hydration for their well-being and productivity.
