Question

Name cattle breeds in which bulls tend to have heavier weight calves and therefore are less calving ease.

Answer 1

Cattle breeds such as Chianina, Charolais, and Simmental tend to produce heavier calves, leading to less calving ease and potentially more difficult deliveries.

Step-by-step explanation:

The question revolves around identifying cattle breeds known for producing heavier calves that can lead to more difficult calving. Breeds such as the Chianina, Charolais, and Simmental tend to have larger birth weights, resulting in less calving ease. These breeds have been selected for traits including size and weight gain, but a consequence of this selective breeding has been an increased incidence of calving difficulty (dystocia), particularly when these bulls are crossed with heifers or cows of smaller breeds. Farmers and ranchers need to manage their breeding programs accordingly to minimize calving complications while still achieving their desired production goals.
