Detergent Fiber Analysis and Forage Quality

Flashcards based on lecture notes about Detergent Fiber Analysis and Forage Quality.

What does Neutral Detergent Fiber (NDF) represent?

Includes cell content and cell wall components.

What does NDF correlate to in forage quality?

A measure related to feed intake based on gut fill.

What is the formula for Dry Matter Intake (DMI) as a percentage of Body Weight (BW) based on NDF?

DMI (% of BW) = 120 / % NDF in forage

What does Acid Detergent Fiber (ADF) correlate to in forage quality?

A measure related to digestibility.

What is the formula for estimating Total Digestible Nutrients (TDN) from ADF?

TDN (%) = 88.9 – (0.779 × %ADF)

What does TDN stand for?

Total Digestible Nutrients.

What components are involved when dietary protein enters the Rumen?

Includes RDP (Ruminally Degradable Protein), NH3, and Microbial Protein.

What does RDP stand for?

Ruminal protein degradability

What is Nitrogen Recycling in the context of dietary protein?

Refers to protein that is recycled in the animal's body through the liver, kidney, and urine.

What is MP in the context of protein digestion?

Microbial protein.

What does it mean to 'feed the microbes' in the context of RDP requirements?

Supply microbes with adequate nutrients.

Meeting RDP requirements leads to optimal fermentation, improving what two aspects?

Microbial protein supply and forage utilization.

What is the basic principle behind RDP requirements?

RDP requirement = microbe requirement

What is the formula for calculating microbial protein based on TDN intake?

Microbial protein = 10.44% × TDN intake

When calculating RDP needs, what should we consider as a source of RDP?

RDP from hay
