Grass Tetany
hyperexcitability,
muscle tremors,
stilted gait,
dullness,
hindlegs extended backward,
death
parturient paresis (milk fever) in ewes
Mg requirement of small ruminants
3 mg/kg BW or 120 mg/kg milk lactating
decrease in Mg intake and absorption
grass tetany
decrease in Ca intake
parturient paresis (milk fever) in ewes
common type of photosensitization
Type 3 - Hepatogenous
-Photophobia
-Scratch ears, eyes, muzzle
-Erythema → edema → serum exudation →
scab formation → skin necrosis
Photosensitization
-restlessness
-uncoordinated movements
-partial paralysis → staggering gait → unable to
rise
transport tetany
lowered production,
retarded growth,
delayed puberty,
lowered reproductive performance,
likely to consume toxic plants
energy deficiency
animals chew and lick various objects
mineral (Sodium chloride) deficiency
-Lambs: knock-kneed, slow growth, unthriftiness, poor appetite
Minerals (Phosphorus) deficiency
-Blood phosphorus declines quickly on a _____-deficient diet
phosphorus
anemia, bone fragility, loss of hair, and poor wool growth in sheep (steely wool)
Minerals (Copper & Molybdenum) deficiency
hypomagnesemic tetany
Minerals (Magnesium) deficiency
-Poor growth, marked impairment of wool
growth in sheep
Sulfur deficiency
