Q2 Exam 1 Flashcards
(56 cards)
Early embryonic death
pregnancy loss prior to day 42
metritis- common causative agent, symptoms, tx
trueperella pyogenes, postpartum severe infection where cow is systemically sick and brown fetid discharge, ceftiofur, fluid therapy, NSAIDs
pyometra- signs, tx
postpartum ovulation before elimination of bacterial contamination (if during breeding season, trichomoniasis), sustained by CL, give PGF2-a
endometritis- tx
no treatment required because not systemically sick
how long is uterine involution and the voluntary waiting period?
28 days, 60d for dairy and 82 days for beef
cystic ovarian disease- dx, tx
palpation and u/s (cysts >2.5cm diameter), follicular cyst treat with GnRH, luteal cyst treat with PGF2-a
freemartin dx
measure length of vagina before one month of age, should be 13cm
polled intersex syndrome
male psuedohermaphrodite, testosterone but sterile, has variable external sex characteristics but male testes in abdomen (still testosterone though)
common goat cryptorchid
90% unilateral cases are R testis in the abdomen
common causes of orchitis in camelids, sheep, and cattle and dx
camelids- fighting
sheep- brucella ovis (not zoonotic)
cattle- not frequent but almost always infectious (coliforms, Trueperella),
dx is culling
penile hematoma- signs, tx
rupture of the tunica albuginea while breeding, symmetric swelling just cranial to scrotum, will progress to abscess if untreated, prognosis based on size (smaller than 20cm, likely to recover with support and 6m sexual rest, bigger needs $ surgery)
tx is broad spectrum abx (ceftiofur, maybe tulathromycin if abscessed), hydrotherapy and NSAIDs
which breeds are most susceptible to preputial lacerations, tx
Bos indicus, tx with ceftiofur, petercillin topical, bandage+pessary, hydrotherapy and NSAIDs
what causes EEDs in cattle
Tritrichomonas foetus
Heat
cystic ovarian disease
Campylobacter fetus spp. veneralis
IVP embryos
Mid gestation abortion causes
Neospora caninum
Iatrogenic (really any time)
Late gestation abortion
lepto
listeria
BHV-1
Brucella
foothills abortion
pine needle abortion
BVDV time of infection to cause different signs
<30d EED, congenital defects
25-150d PI calf
80-150d possible congenital defects or abortion
>150d usually have pre-colostral antibodies
BHV-1 signs
respiratory disease and abortion, 4-8m gestation, fetal autolysis
Neospora caninum
dogs definitive host, recommend culling dams
top three causes of abortion in SR
Chlamydophila- goats, dam/doe sheds three weeks after aborting, placentitis, tetracyclines
Toxoplasmosis- no tx, cats
Campylobacteriosis- sheep (jejuni or fetus fetus), tetracyclines to entire flock, isolate infected ewes, target lesions on fetal liver
Brucellosis and psuedorabies in swine
reportable but eliminated in commercial breeds
brucella zoonotic!!
PRRS
repro and respiratory signs, total depop quickest and most effective to eliminate virus
bovine, caprine and ovine, and porcine gestation length
bovine- 283d
caprine and ovine- 150d
porcine- 114d
camelids- 335 to 365d (11-12m)
neonate physiologic parameters
holds head up-15min
sternal- 30min
standing- 60min
nursing- 120min
neonatal acute respiratory distress syndrome (NARDs)
tachypnea, cyanotic, respiratory acidosis
