Forage Quality and Plant Nutrition

The video discusses the factors influencing forage quality, such as cell wall to cell content ratio, lignification, and anti-quality factors. It compares the nutritional value of various plants, highlighting that leafy plants generally offer higher nutrition. The video also explores the differences between forbs and grasses, the impact of seasons on forage quality, and how different animals have specific forage preferences.

What are the three main factors that influence the forage quality of a plant?

• Sunlight exposure, soil type, and plant height

• Leaf size, root depth, and water content

• Seed size, growth rate, and color

• Cell wall to cell contents ratio, lignification, and anti-quality factors

Why is arrow leaf balsam root considered more nutritious than western yarrow?

• It has a deeper root system

• It is more leafy with a higher cell contents to cell wall ratio

• It grows faster

• It has thicker stems

What makes forbs generally more nutritious than grasses?

• Forbs have thicker cell walls

• Forbs contain more soluble compounds and have thinner cell walls

• Grasses are easier to digest

• Grasses have more vitamins

Which plant is known for its white latex that provides energy compounds?

• Western yarrow

• Deer brush

• Taper tip hawksbeard

• Crested wheatgrass

How does the growth stage of a plant affect its nutritional value?

• Growing plants have more soluble nutrients and energy

• Nutritional value is constant regardless of growth stage

• Dormant plants have more nutrients

• Mature plants are always more nutritious

What happens to the nutrients in a plant during the dormant season?

• They increase due to photosynthesis

• They are leached out if it rains

• They remain unchanged

• They become more concentrated

Why is winter fat considered a better forage option than shad scale for deer?

• Shad scale is toxic

• Winter fat has thinner, less lignified stems

• Winter fat has thicker stems

• Shad scale is more leafy

What is a significant anti-quality factor found in lupine?

• Presence of alkaloids

• High sugar content

• Excessive water content

• Lack of vitamins

How do animals like sheep and goats affect the growth of leafy spurge?

• They fertilize it, promoting growth

• They have no effect on it

• They suppress it through targeted grazing

• They avoid it, allowing it to spread

Why is salt cedar not a preferred forage plant for most animals?

• It has a high sugar content

• It accumulates too much salt

• It grows too slowly

• It is too leafy
