Trace Minerals Flashcards
What are trace minerals?
Elements required in extremely small concentrations in the diet requirements typically measured in ppm
The trace minerals
Iron copper zinc magnesium iodine selenium cobalt fluoride chromium molybdenum
Iron functions
Oxygen transport component of hemoglobin and myoglobinChemical reactions component of enzymes
Iron sources
Redmeat organ tissues. Milk. Many plant materials.
Iron deficiency
Causes: low dietary intake high intake of chemicals that reduce iron absorption. Blood lossSymptoms: anemia fatigue Pica
Iron toxicity
Rare as the body normally limits absorption will cause liver kidney and heart damageISD iron storage disease
The vitamin C connection to iron
Vitamin C increases iron absorption is the reasoning for limited citrus fruits in ISD species
Copper functions
Formation – growth of blood cells melanin production
Copper sources
Organ meats plant levels depend on levels in Soilwork Plantas ground
Copper deficiency
Causes: low dietary copper. Excessive dietary Mo Zn or sulfates
Calcium toxicity
Causes: excessive supplementation high sensitivity species must be managed on low calcium diet results in organ damage and death
Zinc functions
Protein and DNA synthesis chemical reactions
Zinc sources
Animal tissues. Levels in plant tissues vary Galvanized troughs used for feeding and watering
Zinc deficiency
Symptoms: thickening of tongue and skinPoor feathering enlarged legs Fin and scale erosion
