Flashcards in canine pregnancy Deck (21):
cannot be used as a way to determine pregnancy. CL dependent throughout term. p4 is high in diestrus whether or not you are pregnant.
endotheliochorial, zonary, deciduate. marginal hematomas present. iron source for fetus. green pigment on placenta is uteroverdin. if seen , EMERGENCY. premature placental separation.
fetus- 1 month after LH peak. harder after 35 days, vesicle elongates.
useful at 3-4 weeks after LH peak. use bladder as landmark. not a vesicle. not useful in counting number of feti. heartbeat at 23-25d after LH peak. normal is >180bpm. stress decreases it. detect fetal death, mummification, fluid, pyometra, endometrial cysts, anembryonic sacs.
used for pregnancy diagnosis. produced by placenta. 21-22 days post breeding. check again in one week if not there initially. or check once 28d post LH peak
late gestation fro litter size. connecting skull to spine. calcify skulls at 45d post LH. dont go by enlarged uterus. can be pyometra not pregnancy. not definitive. teeth calcify at 63 days. not recommended at early because radiation and not useful. last week of gestation for count
detect pregnancy. elevated in pregnant bitches. also pyometra. not used in usa.
• 65 + 1 days post LH peak
• 57 + 1 days post DIESTRUS cytology
• 57-72 days from 1 breeding
• Generally, within 1 day – body temp fall
• A probably safe
• B “safe if used cautiously”
• C some risks; risk/benefit ratio for use
• D contraindicated (testosterone)
• X absolutely contraindicated
physiological changes of pregnancy
Normocytic normochromic anemia
– Increased plasma volume
• Seen in both bitches & queens
• Increased total protein
– acute phase/fibrinogen
• Energy homestasis
– gestational diabetes mellitus (progesterone inhibits insulin) & ketosis potential
no live vaccines given if pregnant. continue with HWP and tick prevention.
maintendance diet to 3rd trimester, then switch to puppy food to support growth of fetus and lactation. NO CALCIUM SUPPLEMENTS. NO RAW DIETS. infections.
p4 supplements to maintain pregnancy. discontinue before parturition. dont use in early gestration- promites masculinization. recheck for fetal viability and p4 levels
canine herpes virus
kidney pettechiae is pathognomonic. lethal to bitch in 3 week pre and post partum. mummy, abortion, stillborn, premature.
cat gestation length
CL dependent to term. p4 not used for pregnancy dx. relaxin stimulate prolactin release, which is luteotrophic. prolactin reliable pregnancy diagnose in blood and urine at 28 days. longer pregnany diestrus than non pregnant. queens docile and mammary glands change at 3 weeks.
palpate for cats
>2 week.s ultrasound at 2.5 weeks post mating. heartbeat 16d.
diagnostic test cat pregnancy
relaxin at 28 days, serum and urine
radiology for cats
After 38-43 days gestation to see
calcification, skull & other parts
• Fetal molars calcify at 56-63 days
• Crown rump length to estimate gestational
normal maitenance first month, 1.5x maitendance second month, 2x maitenance last month. important to have taurine.
