What is the most common cause of surgical failure following bovine abomasopexy?
Answer: Abomasal adhesion failure leading to re-displacement
Failure of the abomasal fixation to hold, allowing re-displacement, is the most common cause of surgical failure, particularly with blind techniques like toggle-pin.
A standing cow under left paravertebral nerve block shows incomplete desensitization of the caudal flank. Which nerve was most likely missed?
Answer: Lumbar nerve L4 (iliohypogastric)
The L4 (iliohypogastric) nerve provides sensation to the caudal flank, and its incomplete block in the paravertebral technique results in residual sensation in that area.
Which antibiotic is prohibited from extra-label use in cattle in the United States?
Answer: Cephalosporins (at non-approved doses, routes, or for non-approved species)
FDA regulations prohibit extra-label use of cephalosporins in cattle to preserve their efficacy as critically important antimicrobials in human medicine.
What is the primary risk of using xylazine in late-term pregnant cows?
Answer: Premature uterine contractions and fetal stress
Alpha-2 agonists like xylazine can stimulate uterine contractions and cause fetal hypoxia, increasing the risk of premature labor in late-term bovine patients.
What is the recommended body position for a cow undergoing ventral midline celiotomy?
Answer: Dorsal recumbency
Ventral midline celiotomy requires the cow to be in dorsal recumbency to provide access to the ventral midline and abdominal viscera.
During a bovine laparotomy, a pink, gas-filled viscus with longitudinal bands (taenia) is identified. What structure is this?
Answer: Cecum
The bovine cecum is a large, blind-ended sac with visible taenia (longitudinal muscle bands) and is commonly found on the right side of the abdomen.
Which suture material is most appropriate for closing the bovine rumen wall during rumenotomy?
Answer: Polyglactin 910 (Vicryl) in an inverting pattern
Polyglactin 910 (Vicryl) provides adequate tensile strength, is absorbable, and when placed in an inverting pattern (Lembert or Cushing), prevents leakage of ruminal contents.
