4th exam (T or F) part 2 Flashcards
Parturition is inititated with secretion of estrogen, oxytocin & protaglandin 2 alpha that triggers cervical dissolution and uterine contraction.
FALSE — initiated by prolactin
Fetal gonads secrete estrogen and testosterone to ensure development of the Wolffian duct and Mullerian duct, respectively.
FALSE — baliktad
There are different prostaglandin F2 alpha analogues in the market and this is indicate in cases of stillbirth, mummification and retained placenta.
TRUE
Prestimulation of the mammary gland in lactating cows increases oxytocin and prolactin secretion to maximize milk ejection for a short duration of time.
FALSE — no prolactin
The foal can have different presentations in the birth canal and in cases of breech position of foal, it can cause dystocia in a mare.
TRUE
The different domestic animals have variable number of chromosomes and in pigs, the normal chromosome number is 36
FALSE — 38 or 39
Occurence of non-disjunctive ovum or spermatozoa can lead to different chromosomal aberrations including the underdeveloped testes in horses and cats due to aneuploidism.
TRUE
Domestic chickens only have a functional left ovary while the falcon and kiwi possess function left and right ovaries.
TRUE
The domestic chicken’s reproductive tract develops and the magnum is an important part which serves as the site of fertilization for layers.
magnum —> infundibulum
Estrogen is needed during parturition because it increases the number of oxytocin and prostaglandin 2 alpha receptors in the myometrium.
FALSE — Oxytocin only
The female reproductive tract of the domestic chicken have specific functions which includes the formation of the albumen for the egg which occurs in their uterus
FALSE — (uterus)– magnum
It is vital that the newborn offspring suckle the colostrum during the first few hours of nursing, the immunoglobulins that are heavily absorbed in the small intestine of the offspring are IgG, IgE, IgM and IgA.
FALSE — No IgE
Uterine prolapse is a common postpartum problem in domestic animals due to prolonged dystocia.
TRUE
Among the different part of the female reproductive tract of the domestic chicken, the magnum is the site of formation of the shell membranes of the egg.
FALSE – isthmus
During parturition, a combined uterine and abdominal contraction are needed for expulsion of the fetus and placenta
FALSE — only in fetus
Anasarca in a kid is best managed by doing cesarean section.
FALSE — Mutation or forced extraction
Parturition in domestic animals is divided into stages with stage 3 characterized by increased intensity of uterine contraction for placental expulsion.
FALSE — amplitude
Vulvar swelling and reddening and stringing mucus for vulva are initial signs of impending parturition.
TRUE
A large fetus can cause dystocia in cats and is best managed by injecting oxytocin to stimulate uterine contraction.
FALSE
Exhaustion of uterine muscles due to prolonged dystocia is frequently encountered in bitch.
FALSE — in mare, cow, caracow
Among the different avian species, the mallee fowl and pigeon sire perform parental care.
FALSE — Pigeon is biparenteral
Among the different obstetrical manipulations, fetotomy is usually done in cases of fetal emphysema in sheep.
FALSE — mutation or forced extraction
Egg formation in domestic chickens occurs for 18-21 hrs.
24-26 hours
Primary uterine inertia is frequently observed in mares.
FALSE
A mummified kitten is best managed with the use of synthetic oxytocin or prostaglandin 2 alpha.
Cesarean is usually done to deliver large fetuses or in cases of small pelvic canal in dogs.
In mares in parturition, stage 2 parturition is about 1-2 hrs.
FALSE — 0.2 to 0.5 hrs
The ovum contains the barr body and in domestic mammals are heterozygous.
FALSE — Homozygous
The maternal hormones relaxin and estrogen promote softening of pelvic ligaments to facilitate birth of fetuses.
FALSE — relaxin only
Precocial animals give birth to offspring that are fully developed.
FALSE — Advancedly
Artificial insemination in sows uses an AI catheter junction of the female reproductive tract.
FALSE — cervix
Chimera in bulls leads to hermaphrodism.
heifer
Oxytocin initiates parturition in dogs and cats.
FALSE — cortisol
Suckling, and use milk machine can stimulate milk ejection in farm domestic animals by stimulating oxytocin secretion.
TRUE
Among the different domestic animals, the sow or gilt have a litter size range of 10-18.
Engagement of fetus head in the cervical canal initiates ferguson reflex to facilitate oxytocin secretion and release from the posterior pituitary gland.
TRUE
Crop weight increases during hatching to post-hatching in pigeons due to crop milk production controlled by prolactin.
FALSE Prelaying to hatching
The chorion and allantois are the fetal membranes that form the placenta.
TRUE
Progesterone is secreted by the trophoblastic cells of the placenta and corpus luteum in cows and sows to maintain pregnancy.
FALSE — relaxin
During the first stage of lactation, colostrum is formed for maternal transfer of immunity.
TRUE
In sows, detection of fetal heartbeat during the first 1/2 of pregnancy using the doppler and specifically placing the probe of the doppler at the level of the 3rd teat from the last teat of sows.
TRUE
Domestic animals manifest parental behaviors to nurse their young and for the cow their calf follows their mother for nursing as the dam forage.
FALSE — Cow is hider not follower
Nest building and consumption of placenta are examples of maternal behavior exhibited by dogs and cats.
FALSE
Conjoined twins of kittens are best managed with extraction.
Flexed forelimb of a calf can be manually corrected for delivery through mutation.
TRUE
Administration of doxapram orally & oxygenation are beneficial for puppies or kittens delivered by cesarean section.
FALSE — tongue
Mutation is preferably done for dropsy.
Uterine prolapse in goats is best managed by slaughter.
The maternal hormones relaxin and chorionic gonadotropins are needed for pregnancy and are secreted by the amniotic cells of the placenta.
