Why are dairy cows more likely to suffer with hypocalcaemia?
due to high milk yield, Ca demand is elevated
Usually occurs 24hrs before to 48hrs after calving
What is the main effect of hypocalcaemia?
Reduced muscle contraction
Why can hypocalcaemia lead to mastitis?
Teat cannot close fully due to loss of smooth muscle function => exposed to bacteria and infection
Decreased immune function
Describe the effects of hypocalcaemia
Decreased skeletal muscle contraction - affects posture and gait
Reduced cardiac muscle contractility - affects function and circulation
What are the clinical signs of hypocalcaemia on the skeletal system?
What are the effects of hypocalcaemia on the repro system?
What is the effect of hypocalcaemia on cardiact function?
what is the effect of hypocalcaemia on GI function?
