ANSC Feeds Practice Exam

Comparatively, field losses are higher when making which of the following?

1. Hay

2. Silage

3. Grains

4. Pellets

The correct answer is: Hay

Field losses refer to the amount of feed that is lost during the harvesting and processing stages before it is collected for use. When it comes to the production of hay, field losses tend to be higher compared to silage, grains, or pellets for several reasons. Hay production involves cutting grass or legumes and allowing them to dry in the field before being baled. During this drying process, there is a risk of weather damage, such as rain or high winds, which can lead to significant nutrient loss and spoilage. Additionally, if hay is left too long in the field, it can deteriorate in quality as it continues to lose moisture and nutrients, resulting in added losses. In contrast, silage is harvested at a high moisture content and fermented in an anaerobic environment, which helps to minimize field losses as the material is quickly ensiled. Grains are typically harvested using combines that are designed to efficiently collect the grains with minimal loss. Pellets, being a processed feed form, do not incur field losses in the same context since the raw material is typically collected and processed under more controlled conditions. Overall, the nature of hay production—with its dependence on favorable weather for drying and potential for decomposition if mishandled—leads to comparatively higher
