Minerals |
minerals are substances found in food that your body needs for growth and health. There are two kinds of minerals: macrominerals and trace minerals. Macrominerals are minerals your body needs in larger amounts. |
|

Regulation of osmotic pressure and pH in an animals body fluid |
|
Cobalt function |
Structural component of vitamin B12 |
|
Iodine function |
Component of thyroid hormone |
|
Iron |
Essential constituent of hemoglobin in the blood and myoglobin in muscle tissues |
|
Vitamins |
Organic substances required by animal tissuses in very small amounts |
|
Vitamin A function |

When is the best time to cut legumes or grass to make hay |
When the blooms first begin to appear |
|
3 steps to making hay |
Cutting Curing Storing |
|
Pasture |
An improved or unimproved plant material on land areas where animals graze |
|
Green chop |
Herbage that has been cut and chopped in the field and fed fresh to live stock in confinement |
|
Silage |
Chopped plant material that has been fermented |
|
Haylage |
Silage that contains less than 50% moisture |
|
How to make silage |
Plant materials are ensiled under anaerobic condition. It is then undergoes controlled fermentation thst produces acid which kills off bacteria/mold ect. It is then packed tightly into bunker silos or upright silos to keep its optimal dryness of 30-45% |
|
What is the ideal pH of silage |
Atmost 4.2 |
|
Corn characteristics |
Corn can ether be ground, cracked or rolled |
|
Sorghum or milo |
Small round, relatively hard seeds |
|
Batley grain |
Brown seeds |
|
Advantage of molasses |
Maximize rumen productivity, reduce dust, aid pellet quality and serve as medium for feeding medication |
|
Disadvantages of molasses |
Can create problems with mixing and equipment handling at the feed mill |
|
Whats kelp meal made from |
Seaweed |
|
Protien quality |
Measure of how much the amino acid content of a protien supplement resembles the amino acid requirements of the animal to be fed |
|
Plant source of protien supplements |

|
Animal protien source |
Blood meal Feather meal Meat meal |
|
Non nitrogen protien supplements |
Urea Biuret |
|
Distillery and Brewery by-products |
Distillers dried grain Brewers dried grain Corn gluten meal |
|
Buffers |
Added to counter act acid generated by ruminal fermentation of grain |
