Forage vs Concentrate feeds

Question 1

Why do mono-gastric animals require a higher proportion of concentrate feeds and less fibre?

Answer 1

They have a limited capacity to digest fibre and thus require diets of higher nutrient density

Question 2

What prevents spoilage of silage?

Answer 2

The pH should drop to 4 within the first 72 hours after oxygen is expelled. This prevents spoilage

Question 3

Minimum peNDF requirement for dairy cattle?

Answer 3

22%

to adequately stimulate
the amount of chewing activity required to maintain an
average rumen pH of greater than 6.0

Question 4

Minimum peNDF requirement for beef cattle?

Answer 4

Beef cattle = 8.5-9 % peNDF, beef cattle produce less energy so require a lower intake, eating requirements are less

Question 5

What is peNDF?

Answer 5

Physically effective NDF attempts to take into account
both the chemical and physical nature of fibre that
influences the chewing activity and ruminal function of
ruminants.
