Thin Beef Cow Flashcards
What are the parameters of beef cow BCS for idiots?
(Fat in the tail head six or greater, no fat in the tail head, five or less!; make sure you make a song out of it and you won’t forget)
If you’re looking at a herd of beef cattle and notice the majority are 3 or 4 BCS, where must the issue lie?
(Nutrition)
Where do you see prominent fat in beef cows with a BCS of 8 or greater?
(The brisket)
Is it easier or harder to have a fall calving cow at a good BCS during calving?
(Easier, lots of good grass mid to late gestation in fall calving cows; it is hard for them to gain weight during the breeding season which can decrease fertility)
Is it easier or harder to have a spring calving cow gaining weight during breeding season?
(Easier, lots of good grass around breeding time for spring calving cows; it is hard for them to have a good BCS at calving which can increase their time to cycling post calving)
What are the two pathophysiologic causes of bottle jaw?
(Hypoproteinemia (Johne’s) and right sided heart failure)
How can you tell the difference between an abscess or lumpy jaw causing a unilateral swelling of a cow’s jaw?
(Abscess will be freely movable, cannot move lumpy jaw lesions because they are associated with the bone)
How can you tell the difference between lumpy jaw and bottle jaw?
(Bottle jaw will be in the center of the mandible, lumpy jaw will usually be unilateral)
What are the main clinical signs seen in early infections with Mycobacterium paratuberculosis in cows?
(Diarrhea, and weight loss with a normal diet)
Fecal culture for Johne’s disease has been replaced with what test which is more expensive but much faster for testing individual animals?
(Fecal PCR)
What are the two fundamental principles to controlling Mycobacterium paratuberculosis on a farm?
(Prevent newborns/young calves from ingesting feces and getting rid of sick cattle asap to reduce total farm environmental contamination)
What are the three clinical signs of traumatic reticulopericarditis?
(Bottle jaw, murmur, and distended jugular veins)
After M. paratuberculosis is ingested, the bacteria are taken up by cells in what organ where they multiply and cause thickening and chronic inflammation?
(The ileum)
Why does hypoproteinemia result from an infection of Mycobacterium paratuberculosis?
(The ileum cannot absorb amino acids d/t inflammation and there is also a loss of protein into the intestinal tract at the ileum)
