Ketosis Flashcards
ketosis is a common periparturient disease/metabolic disorder in
dairy cattle
what causes ketosis
the energy needed for maintenance and production is greater than what the animal takes in (negative energy balance)
what happens once body enters ketosis
body uses fat to make energy, fat enters kreb’s cycle to make ATP
byproduct of ketosis, what they cause
ketones; mildly toxic, cause decreased appetite, mild depression of senses
signs of ketosis
agalactia, anorexia (decreased appetite), lethargy/depression, hypermotile rumen, may smell ketones on breath urine or milk, may have “nervous ketosis” (hyperexcitability/ bizarre behavior)
when milk production should peak
just after calving
define agalactia
decreased milk production
how to diagnosis ketosis
- ketourial test for ketones in urine (ph turns pink/purple)
- low blood glucose
how to treat ketosis
- increase blood glucose
- stimulate appetite
- glucose IV (SQ or IM can cause abscesses)
- oral administration of glucogenic compounds
preventing ketosis
keep cows eating through peak milk production time, increase feed quality, feed higher energy diets, avoid issues like milk fever or retained placenta
what causes a displaced abomasum
abomasum fills w gas and moves from the ventral abdominal (L or R)
displaced abomasum seen in
high producing cows fed rations high in grain/silage, low in roughage (produce more gas)
signs of displaced abomasum
anorexia, hyogalactia/agalactia, small amounts of soft manure (bc kinked intestines), ketouria (bc not eating enough), “ping” upon auscultation
most common kind of displaced abomasum
LDA (rumen pins it down)
what is a torsion
organ twists on long axis
