MAINTENANCE (state)

MAMMALS

A class of vertebrate animals distinguished by self-regulating body temperature, hair, and in the female (a) milk producing gland(s).


MASTICATION

To grind or crush (food) with or as if with the teeth to prepare it for swallowing and digestion (Syn: Chew).


MASTITIS

MEAN (Statistics)

The mean of a normal distribution is the most likely value (the value that has the lowest probability of being "wrong"). The mean is the best measure of central tendency of a normal distribution. With a normal distribution, approximately one-half of the samples have values lower than the mean and one-half have values higher than the mean.


MEGACALORIE

METABOLISM

Refers to all of the changes that nutrients undergo after they are absorbed from the digestive tract. Metabolism is divided into anabolism and catabolism.


METABOLITE

A product of metabolism of nutrients.


METABOLIZABLE PROTEIN

In ruminant nutrion, metabolizable protein, often abbreviated MP, is the amount of digestible protein that reach the small intestine, which is the source of amino acids absorbed into the blood. The three main sources of MP include rumen undegraded protein (the dietary protein fraction that has not been degraded in the rumen), the microbial (bacterial) protein synthesized in the rumen from the fermentation process, and the endogenous protein (intestinal digestive enzymes and sloughed cells from the gastro-intestinal tract). The latter source is minimal.


METRITIS

Inflammation of the uterus.


MICROBE

Animal or vegetal organism of microscopic dimension (syn Microorganism).


MICROORGANISM

(see Microbe).


MILK FEVER

Condition that occurs immediately or within the first day after calving. The cow has cold ears and a dry muzzle. This condition is due to a calcium imbalance. As opposed to what the name implies, there is no "fever", but rather a paralysis of the limbs.


MILL (a)

1. A building equipped with the machinery for grinding grain into flour or meal. 2. A device or mechanism such as rotating millstones, that grinds grain.
