Nutritional deficiencies Flashcards
Signs:
-lowered production
-retarded growth
-delayed puberty
-lowered reproductive performance -likely to consume toxic plants
energy deficiency
Often with energy shortage, Feed intake depressed, growth seriously retarded
protein def.
__ is also needed by rumen microflora
Protein
Animals chew and lick various objects
-Feed consumption declines
-Drop in body weight and milk production
NaCl def.
spontaneous fracture of bones; retarded general growth & development
Ca def. in youngs
Almost all non-legume forages and concentrates require __ supplementation (e.g. bone meal)
Ca
manifests as knock-kneed, slow growth, unthriftiness, poor appetite in lambs
Phosphorus def.
manifests as low milk production, fragile bones, low conception rates in adults
Phosphorus def.
what will happen if sheep are given excess P
urolith formxn
Cs: Anemia, inappetence, retarded growth, rough hair coat, low milk production
cobalt def.
cs: General signs of deficiency include anemia, bone fragility, loss of hair, and poor wool growth in sheep (steely wool)
cu and molybdenum def.
how to prevent cu and molybdenum def.

Poor growth, marked impairment of wool growth in sheep
sulfur def.
Skeletal abnormalities
manganese def.
Synthesized in tissues of even young ruminants
vit c

-Synthesized by rumen bacteria
b complex vits
Synthesized by rumen bacteria and distributed widely in green, leafy forages
vit k
assoc with white muscle disease in young
Vit E , Selenium
closely related minerals to Vit D
Ca P
Poor mineralization → cartilagenous overgrowth and disorganization → swollen leg joints and beaded ribs (rickets)
vit D
Vit D deficiency prevention
