Commonly known as corn, is a cereal grain. In the United States and Canada, the primary use for maize is as a feed for livestock, forage, silage or grain.
|
|
| Manifold |
| |
A fluid conductor which provides multiple connection ports.
|
|
| Manual control |
| |
A control actuated by the operator, regardless of the means of actuation. Example: Lever or foot pedal control for directional valves.
|
|
| Manual override |
| |
A means of manually actuating an automatically-controlled device.
|
|
| Material balance |
| |
A relationship, often portrayed in a diagram, that shows how all components of a raw material are allocated and used.
|
|
| Meal |
| |
A dry mix of feed ingredients, usually with the individual feeds distinguishable in the mix.
|
|
| Meat and Bone Meal (MBM) |
| |
Is a product of the rendering industry primarily used in the formulation of animal feed. In most parts of the world, MBM is no longer allowed in feed for ruminant animals (fear of spread of BSE, mad cow disease).
|
|
| Mechanical control |
| |
Any control actuated by linkages, gears, screws, cams or other mechanical elements.
|
|
| Megacalorie (Mcal) |
| |
Units used to describe quantities of energy in a large animal’s diet. Equal to 1,000 kilocalories (Kcal).
|
|
| Metabolised |
| |
The process whereby the food is digested to enable the animal to utilise the nutrients.
|
|
| Metabolizable Energy (ME) |
| |
The digestible energy intake minus the energy in the urine minus the energy in the gaseous product of digestion. The ME value of individual feeds is rarely measured.
|
|
| Metabolizable Protein (MP) |
| |
Protein (amino acids) that is actually absorbed from the gut. MP consists of protein in the rumen, microorganisms, feed protein and any protein that bypasses digestion in the rumen.
|
|
| Meter |
| |
To regulate the amount or rate of fluid flow.
|
|
| Meter-in |
| |
To regulate the amount of fluid flow into an actuator or system.
|
|
| Meter-out |
| |
To regulate the flow of the discharge fluid from an actuator or system.
|
|
| Metre (m) |
| |
The metric basic unit for linear measurement equal to 39.37 inches (1.094 yards).
|
|
| Microbes (microorganism) |
| |
Any organism, such as a germ, virus, or pathogen, of microscopic size.
|
|
| Micron |
| |
One-millionth of a metre or approximately .00004 inch.
|
|
| Micron rating |
| |
The size of the particles a filter will remove.
|
|
| Mile (mi) |
| |
A unit of linear measurement on land, equivalent to 5,280 feet (1,760 yd) or 1.6 kilometres.
|
|
| Mill |
| |
To Mill, verb - grind ingredients to make Meal or noun - a synonym for Meal.
|
|
| Milligrams in a Kilogram (mg/kg) |
| |
Units of concentration. This measure is the same as parts per million (ppm). 1 mg/kg = 1 ppm
|
|
| Millimetre (mm) |
| |
A unit of length equal to one thousandth of a metre (0.0394 inches).
|
|
| Minerals (major) |
| |
Minerals such as calcium and phosphorous that are included in a ration in relatively large amounts. Usually measured in grams per day.
|
|
| Minerals (minor/trace) |
| |
Minerals such as copper and zinc that are included in a ration in very small amounts. Usually measured in 1/1000 of a gram or milligrams per head per day.
|
|
| Mixer |
| |
Mechanical means of achieving a balanced feed ingredient formulation. Two basic types exist, vertical mixers and horizontal mixers.
|
|
| Mixer (horizontal) |
| |
Horizontal mixers consist of a series of paddles or metal ribbon blades mounted on a horizontal rotor within a semi-circular trough. The blades move the material from one end of the mixer to the other, tumbling it as it goes.
|
|
| Mixer (vertical) |
| |
The vertical mixer consists of one or more vertical screws which elevate the feed ingredients to the top of the mixer where they fall by gravity to the bottom, to be mixed and re-elevated.
|
|
| Modulate |
| |
To control within an infinite range between 0 percent and 100 percent as opposed to on/off control.
|
|
| Monitor |
| |
Screen on which an electronics systems display information.
|
|
| Monogastric |
| |
Non ruminant animal having only one stomach, e.g. pig, human.
|
|
| Motor |
| |
A device which converts electricity or hydraulic fluid power into mechanical force and motion. It usually provides rotary mechanical motion.
|
|
| Motor control center (MCC) |
| |
Central location for circuit breakers for mill equipment.
|
|
| Mycotoxin |
| |
Mycotoxins are substances produced by moulds that contaminate various agricultural commodities either before harvest or under post-harvest conditions. Mycotoxins can appear in the food chain either by being eaten directly by humans, or by being used as livestock feed.
