VET 2505 Pract W

evaluates the male's breeding capability breeding soundness exam
what should you ask to obtain a good history? libido, recognizing females in heat, dominance issues, how many females is he turned out with, structural soundness
physical exam for breeding soundness should include? ID, BCS, TPR, Physical soundness, external sheath, teeth, testes, scrotal circumference
What are you looking for with a rectal palpation for a breeding soundness exam? prostate, ampullae, seminal vesicles are commonly diseased look for assemetry or pain, inquinal rings should not be large
Semen collection should be included in a breeding soundness exam. What are you looking for when evaluating a semen sample? motility: 30% to pass; live vs dead; morphology: abnormal (double heads, tails, decaptiation) mus have 70% normal to pass
Breeding Soundness Exams: Satisfactory result the bull passed all 3 criteria and should be good for breeding
Breeding Soundness Exams: Deferred result the bull did not pass all criteria but should be reevaluated, because the problem may resolve over time.
Breeding Soundness Exams: Unsatisfactory result the bull did not pass all criteria and has a non-resolvable problem
period of follicular development proestrus
estrogen level has reached peak, receptive to male, ovulation soon after estrus
CL begins to develop Metestrus
active, luteal stage, where the CL has reached max size and max effect Diestrus
ovarian inactivity anestrus
synchronizing the estrus cycles of multiple females estrous synchronization
what are the benefits of estrous synchronization? enhances use of AI, breeding schedule can fit work schedules/seasons, reduces labor time, controls birthing season, induces cycles during anestrous
semen is collected and artificially injected into female artificial insemenination
AI is difficult in... sheep and goats
stored in special canisters containing liquid nitrogen, samples should be immediately placed in warm water bath Frozen semen
store/shipped in freezer pack, should use quickly and not open until ready to use Cooled semen
AI is performed vaginally in... horses
AI is performed by rectal palpation in... bovine
this allows for the production of more than one offspring from one cycle rather than 1 per cycle embryo transfer
embryos for transfer can be.... fresh or frozen
in cattle and horses embryo transfer is performed.. vaginally
in sheep and goats embryo transfer is performed... endoscopically/surgically
gestation cycle of bovine 278 days, 9 mo
gestation cycle of equine 330 days, 11 mo
gestationg cycle of ovine/caprine 150 days, 5 mo
gestation cycle of porcine 3 mo, 3 w, 3 d
gestation cycle of camelid 350 days, 11.5 mo
this is a placenta where nearly the whole surface of the allantochorion forms it; horses and pigs diffuse
type of placenta where there are multiple areas of attachments, commong in ruminants cotyledonary
this stage of parturition: fetus has active role, contrations, fetus positions for delivery, ends with passing of allantoic fluid stage 1
this stage of parturition: begins with rupture of chorioallantois; ends with delivery of fetus stage 2
this stage of parturition: delivery of fetal membranes/placenta stage 3
what are the early signs of parturition in equine enlarged vulva, pelvic ligaments relax, udder development 30 days before, waxing up 12-48 hrs prior
what can you see when an equine patient is in stage 1? restlessness, frequent urination/straining, pawing/looking at side, colicky, vaginal discharge, swishing tail or holding up. Can last 30 minutes to 4 hours
how long should stage 2 last in equine patients 20-30 minutes
In equine patients when the fetal membranes/placenta are retained more than 3 hours should you be concerned? Yes. This is an emergency.
early signs of parturition in bovine enlarged vulva, pelvic ligaments relax, vaginal discharge, udder development 30-45 days prior except in 1st calf heifers
what will you see in a bovine patient in stage 1 restless, frequent urination, go off by themselves, hold tail up. lasts 2-8 hours
how long should stage 2 last in bovine patients 30 minutes to 4 hours with progress every hour
how long should stage 3 last in bovine patients 30 iminutes to 12 hours
what are early signs of parturition in ovine/caprine pelvic ligaments relax, vulva elarges, udder developement, vaginal discharge
what will you see in an ovine/caprine patient stage 1 restless, frequent urination, vocalization, lasts 1-4 hours
how long should stage 2 last in ovine/caprine patients max of 2 hours
stage 3 in ovine/caprine should be over within 8 hours
early signs of parturition in porcine udder development ~30 days, stream milk 12 hours before birth
what will you see stage 1 in porcine patients go off feed, restlessness, nesting 12-24 hours
how long should stage 2 last in porcine 1-5 hours, 10-20 min between piglets
stage 3 should be complete within how long with porcine 1-12 hours. retained could mean more piglets
early signs of parturition in camelids udder development, vulva enlarges, pelvic ligaments relax
what should you expect of camelids in stage 1 labor? restlessness, vocalization, frequent defecation/urination, seperation from herd, decreased appetite
how long should stage 2 last in camelids 30-45 minutes.
how long should it take to complete stage 3 for camelids 2 hours
