Basic Aspect of Feeds and Feeding in Livestock and Poultry Flashcards
is rationing feeds short of the proper volume or standard requirement
underfeeding
giving more feed beyond the standard level
overfeeding
feeding enough feedstuff with unbalanced nutritional level
unbalanced feeding
chemical substances found in feed materials that can be used for maintenance production
nutrients
part of a feedstuff that can be digested
digestible nutrient
efficient users of roughage
ruminants and horses
3 basis functions of feed nutrients
- structural materials
- sources of energy
- regulators of body
reasons why animals need feed
maintenance
growth
reproduction
lactation
working
total amount of feed an animal gets in a 24 hour period
ration
ration that provides all of the nutrients needed by the animals
balanced ration
type and amount of feed and water an animal eats
diet
6 types of materials that provide nutrients
carbohydrates
fats
protein
minerals
vitamins
water
major sources are corn, hay, oats
carbohydrates
meat scraps, tankage and fish meal are examples
fats
soybean meal, blood mean, skim milk are example
protein
the most important minerals in animals
vitamin a, d, b
most important of all nutrients
water
% of market hig
40% water
% newborn calf
70% water
more abundant and cheaper
carbohydrates
complex compounds made of amino acids
proteins
the inorganic elements of animals and plants
minerals
the inorganic elements of animals and plants
minerals
deficiency =
loss of production
macrominerals
Salt

Phosphorus
Magnesium
Potassium
Sulfur
Microminerals
Chromium
Cobalt
Copper
Fluorine
Iodine
Iron
Manganese

Zinc
Function of minerals
part of protein
give strength to skeleton
control fluid balance
fat soluble vitamins
vitamin A, D, E, K
Water soluble vitamins
b-6
b-12
c
salt or mineral block
blocks
molasses
liquids
salt, protein sources and other materials
mixes
most important source of energy
carbohydrates
are superior for monogastrics
animal proteins
are abundant in essential amino acids
milk and eggs
nonnutritives
flavor, color, palatability
feed classifications
roughages
concentrates
by-product feeds
protein supplement
minerals
vitamins
special feeds
additives
