BreedingPregnancy diagnosisSome problems during pregnancyVaccination and nutrition programsNormal parturitionDystociaCare of the kid, including colostrumReviving weak kidsFloppy kid diseaseRecord keeping

Pregnancy diagnosis

• gestation ~150 d goat• progesterone a nonpregnancy test• real time ultrasound best• sector scanner ideal (count

fetuses)• transabdominal, esp right side, esp

45-90 days

False pregnancy of goats

• common in pets, out of season breedings, does intentionally not bred

• serum progesterone elevated• fluid but no caruncles or fetus• undulating walls, snow scene if

ballotte abdomen

False pregnancy of goats

• “cloud burst” if self corrects• sometimes bloody discharge as if

aborted• 5-10 mg dinoprost (Lutalyse®) or

125-250 mcg cloprostenol (Estrumate®)

• repeat in 12 days

Tetanus and Enterotoxemia• the simplest

vaccination program

• two or three doses, then boosters at least once a year

• booster before kidding

Abortion diagnosis and prevention

• suspect infectious cause if >2% abort• diagnostic lab support required – fetus,

placenta, paired serum samples• toxoplasmosis, chlamydiosis, Q fever• listeriosis, Cache Valley virus, stress,

iodine or selenium deficiencies

Goiter !

Normal thyroids <2 g

Abortion math

5 abortions in a flock of 50 bred does = 10% = abortion storm, almost certainly infectious

5 abortions in a flock of 500 bred does = 1% and may be normal losses – not concerned yet, but label and save fetuses and placentas

>2% is cause for concern and testing (2 abortions in a small herd)

Mummified fetuses are common with toxoplasmosis; the twin may be normal

Abortion diagnosis and prevention

• most diseases zoonotic• wear plastic sleeves• isolate aborting doe• destroy fetuses and placentas• cull if chlamydiosis, don’t cross foster• inject long-acting oxytet 3X or feed

chlortetracycline (extralabel – need vet)

Do you call this hay?Provide energy, protein, selenium, vitamin E

Pregnancy toxemia

• late pregnant goats carrying multiple kids

• twin lamb disease

inadequate feed offered

fat mobilization

fatty liver

anorexia from other disease

Pregnancy toxemia or ketosis

A full uterus crowds the rumen while kids demand more nutrients

Obese goat in late pregnancy cannot eat much forage

• fat stored in omentum takes up space

• doe becomes ketotic• even though fat,

needs higher quality forage and some grain

Diagnosis of pregnancy toxemia

• standing or lying apart• depressed, may seem blind or grind

teeth• off feed – small fecal pellets• diarrhea when fetuses die• ketones in urine (be ready to

collect !)• ketones in blood (smell breath)

uterus

uterus rumen

omentum has been removed

Normal parturition

• ligaments soften and disappear – within 12 hours of parturition

• doe waits for quiet period in barn• 30 – 30 – 30 rule• ballotte abdomen for additional kid

if suspect a problem

Kidding is close!

Udder fullVulva relaxedSlight mucusLigaments aroundbase of tail gone

Assisting parturition

• wash vulva• sterile glove• lubricant (Dawn)

The glove protectsyou and the doefrom infection

Meconiumstained = Help now!

Correction of dystocia

• elevate hindquarters or turn dam over• lamb puller• epinephrine 1 cc IM• one front leg and head• one hind leg• cut off head if dead• subcutaneous fetotomy• penicillin, flunixin IV, tetanus

prophylaxis

Caesarian section

• if does not respond rapidly to medical treatment of pregnancy toxemia

• if > 141 days gestation• pretreat with 20 mg dexamethasone

if surgery delayed or kids premature, to develop surfactant in the lungs

• local anesthesia injected in the flank or gas anesthesia

• blindfold, don’t give xylazine
