Label the proximate analysis of feed

Chemical Analysis is less in-depth than proximate analysis

Chemical analysis can analyze down to what scales?

What proportion of feedstuff is made up of carbs?

Carbohydrates are made up of [blank_start]sugars[blank_end], and contain carbon, [blank_start]hydrogen[blank_end], and oxygen. Plants make [blank_start]glucose[blank_end] through photosynthesis. The two components of carbohydrates are [blank_start]Crude fiber[blank_end] and [blank_start]Nitrogen-Free extract[blank_end].

NFE: Primarily [blank_start]sugar and starches[blank_end], easier to [blank_start]digest[blank_end] than CF, mostly easier to eat for [blank_start]monogastric[blank_end] animals, contain [blank_start]grains, fine leaves[blank_end]. CF: [blank_start]complex[blank_end] carbohydrate. [blank_start]structural[blank_end] part of plant. [blank_start]Large[blank_end] stems. Can only be eaten by [blank_start]ruminant[blank_end] animals, because of the [blank_start]microbes[blank_end] that can break down lignin. Made of [blank_start]cellulose[blank_end], hemicellulose, and lignin.

What is the ideal time to harvest roughage?

Roughage is high in [blank_start]FC[blank_end], low in [blank_start]NFE[blank_end]. However, the [blank_start]better[blank_end] the quality, the higher the NFE and lower the CF. [blank_start]Younger[blank_end] plants have less CF and more NFE.

Concentrates: [blank_start]High[blank_end] in NFE and [blank_start]low[blank_end] in CF. Consists of [blank_start]cereal[blank_end] grains. Can be digested by [blank_start]Ruminants and Monogastric[blank_end] animals

Fats provide _____ times more energy than carbs

Fats are made up of carbon, hydrogen and oxygen

Unsaturated fats have _____.

How much fat is feed to cattle and lamb feed lots?

If there are enough unsaturated fatty acids in fat, it can last a long time in storage.

Why are fats added to livestock rations? Select ALL that apply

The two systems of measurement of energy in nutrition are: [blank_start]Total Digestible Nutrients[blank_end] [blank_start]Calorie system[blank_end]

Total Digestible Nutrients (TDN)= + % Digestible [blank_start]NFE[blank_end] + % Digestible [blank_start]CF[blank_end] + % Digestible [blank_start]Protein[blank_end] + (% Digestible [blank_start]Fats[blank_end] x 2.25) = TDN

Fill in the blanks:

The most important environmental influence is

Carbs are made up of [blank_start]carbon[blank_end], [blank_start]hydrogen[blank_end] and [blank_start]oxygen[blank_end]

Ruminant animals: [blank_start]Cattle[blank_end], [blank_start]sheep[blank_end], [blank_start]goats[blank_end] Monogastric animals: [blank_start]Pigs[blank_end], [blank_start]horses[blank_end] Other: [blank_start]chickens[blank_end]

How much fat is in a dairy cow ration?
