Metabolic Disorder in Dairy Cattle Flashcards
The failure to adequately fuel the body during lactation can lead to…
Fatty liver and ketosis
Early lactation is associated with…
Displacement of the abomasum and rumen acidosis
What is the transition period?
Last 3 weeks of gestation through first 3 weeks of lactation
Low dry matter intake pre-calving can lead to…
Mastitis, impaired liver function, and displaced abomasum
What causes milk fever?
Acute deficiency of blood calcium post calving
Decreased serum calcium leads to…
Decrease muscle activity and increased risks for abomasum displacement and retained placenta
What are two factors that impair the PTH signaling pathway responsible for milk fever
High potassium diets and low magnesium
Why should calcium be administer slowly
It is cardiotoxic
High potassium in the rumen affects…
Mg absorption
What cows are more affected by ketosis?
Those who are over conditioned in the dry period
What causes fatty liver in ketosis?
When there is decreased feed intake, there is increased blood NEFAs which move to the liver, the liver cannot metabolize all the FAs so it results in ketone body and lipid accumulation
What are two ways to measure ketone levels and which is best?
Urine and milk, milk is best
How do you treat ketosis?
Restore blood glucose levels and reduce fat breakdown
Abomasal atony
Hypocalcemia, lower ruminal fill, endotoxins, excessive concentrate causing acidosis
What is ruminal acidosis
Associated with over-ingestion of rapidly fermentable concentrate feed
