(28 cards)
Requirements for minerals
age
physiological status
body storage
environment
Macro minerals
Calcium chloride sodium sulfur potassium phosphorus magnesium
Micro
copper iodine iron manganese selenium zinc
Calcium
Largest percent of bone deficiencies: rickets osteomalacia wheat pasture
Phosphorus
help in the absorption of calcium deficiencies: Hyper irritation convulsions death vasodilation grass tetany-spring fresh cows
Na/K/Cl
all are electrolytes
Sulfur
help wool quality
def: poor wool
Copper
Help in the formation of red blood cells, reproduction collagen formation
Def: anemia, reprod losses
TOXIC to sheep
Iron
Help in the transport of O2, hemoglobin
Def: anemia thumbs in baby pigs
Selenium
helps and interacts with Vitamin E
Def” white muscle disease in lambs
Zinc
helps with insulin and bone growth
Def. skin flakes(parakeratosis)
source galvanized fence
Fat soluble
VIT. ADEK
Water soluble
VIT C. b6, b12, etc these can be in short storage daily.
VIT A
Helps with vision bone growth
Def: night blindness
VIT E
helps with peroxidase activity
Def: white muscle disease
VIT D
source sun, helps in absorption of Calcium
Def: abnormal bone growth
VIT K
Required for blood clotting
water soluble vitamin C
energy and metabolism
Def: scurvy
Deficiencies can cause
decrease in growth and efficiency and cause no storage and not stable
Why is the nutrient value of feeds important
all food are not equal
Proximate Analysis-chemical procedure
estimates nutrient composition
Nutrient Value of Feeds
estimate: water, crude protein, ether extract, ash, crude fiber, nitrogen free extract
Dry matter measures
water content of feed
crude protein measures
nitrogen content, protein contains about 16% nitrogen. %CP=6.25x%nitrogen
