Term
How does the nutritive value differ between forages and concentrates
Definition
forages usually have a lower digestibility and thus a lower useful energy value than concentrates. Concentrates are lower in fiber and higher in energy.
Term
define ration
Definition
a fixed allotment of feed given to an animal in a 24-hour period
Term
define TMR
Definition
Ration formulated to meet requirements of the animal in which all of the ingredients are blended together in a mixer
Term
Dry Matter
Definition
What remains in the feed when all the water is taken out
Term
Crude Protein
Definition
total available and unavailable protein
Term
crude fiber
Definition
total avaiable and unavailable fiber. two categories are NDF and ADF
Term
define NDF
Definition
neutral detergent fiber; cellulose, lignin, and hemicellulose
Term
define ADF
Definition
acid detergent fiber; cellulose and lignin (cutin, silica, tannins, indegistible nitrogen, and minerals)
Term
define TDN
Definition
total digestible nutrients; the sum of digestible protein, digestible NSC, digestible NDF, smf 2.25xdigestible fat
Term
define RDP
Definition
rumen degradable protein; used to synthesize microbial protein in the rumen, consists of soluble protein and proteins of intermediate ruminal degradability
Term
what does apparent digestibility equal?
Definition
(dietary intake - feces output/ (dietary intake) x 100
Term
what does "apparent" mean
Definition
it is "apparent" because the feces has bacteria and dead blood cells + dead skin. this makes the value lower.
