In a dairy herd, for example, there will be a higher percentage of cows than bulls. This is because cows are the ones who produce milk, so they are more valuable to the farmer. In a beef herd, on the other hand, there will be a higher percentage of bulls. This is because bulls are larger and have more muscle mass than cows, so they are worth more money at market.
Overall, the percentage of cows versus bulls in a population of cattle will depend on the specific circumstances of the herd. There is no one definitive answer to this question.
