Poor body condition (on a scale of 1 to 9, a BCS of 4 or less) will lengthen the anestrus period of that cow. In other words, she will take longer to come back into heat and thus be ready to breed if she were too thin than in normal body condition.
In general, poor body condition can cause anoestrus (anestrus in American English spelling). Anoestrus is an absence of the normal reproductive cycle typically associated with seasonal changes. However, a cow that does not have sufficient body reserves to support a pregnancy may go into anoestrus to prevent further strain on limited resources.
Plainer cattle refer to cattle that are in average condition in terms of body condition score. If we use the American scoring system of 1 to 9, 1 being the most emaciated, plainer cattle are those that fall in between a body condition score of around 5: not too fat, nor too thin.
Hypothermia is a condition that has the potential to affect everyone. This is a condition that happens when the body gets too cold for too long.
Pathological conditions do affect the homeostasis of the body. This is the constant state of the body when it is in good health. An illness will change this homeostasis.
Condition Scoring in Zebu cattle is the same for any and every other breed of bovine: it's a measure of fatness that an animal has that determines that animal's reproductive and feeding ability. See the related question below for more information on body condition scoring.
Fat = energy, and energy means increase in weight gain or body condition in cattle. High energy in feeds is good for fattening cattle up for slaughter, or getting thin cows to put on weight.
How does our physiological state or body condition affect our behavior
Injury, Disease, Illness, Pathology, Pathological Condition
Cerebal Palsey is a condition that primarily affects the brain of the individual afflicted with it. As a result, this condition can have many affects on different parts of the body because the brain controls all functions in the body. It can affect movement, speech, eating, and cause erratic movements.
It depends on the breed, condition, sex, size/weight, time of year and management practices this cattle-beast is and is subject to, respectively. But basically, a cattle-beast will eat 2 to 4% of its body weight in dry matter.
It is a means of measuring the amount of fat that cattle are carrying to determine health, fertility, and feed efficiency of that animal. BCS's are mainly performed in cows and heifers, but it's not uncommon to do a BCS on a bull either.
If by pathological you mean "disease causing", then yes they would throw off the homeostatic condition of the body.
The growth hormones and antibiotics used in the raising of cattle and other meat animals are not passed on to you. They are denatured (changed) when they are cooked and do not act on your body.
