Repro history- previous preg, dystocia and abortion
BCS
FAMACHA
Polled vs Horned Phenotype

Q

Who is more likely to be affected by stress in late pregnancy and what can happen?

A

Goats
-Predator, weather change, shear and heat stress

Decrease repro, fetal waste, EED, abortion, still birth, decreased water intake, exercise intolerance

Prevent - shear, shade, good BCS, trace mineral and water

Q

How does poor BCS effect repro?

A

Suppress libido, EED, decreased fetl growth, decreased placenta, mummification

Over conditioned - hepatic lipidosis and preg tox in late gestation

17
Q

What vitamins are commonly SR ewes deficient in?

A

VA, VE, Selenium, Copper, Manganese and Iodine

18
Q

What causes swayback in newborn lambs?

A

Copper Deficiency

19
Q

How can you determine if the animal is pregnant or has a hydrometra/mucometra?

A

Ultrasound and find anechoic fluid in the uterus but no cardinal signs of pregnancy
(pseudopreg)
High p4 on bloodwork
Goat common - treat with prostaglandin (can do CIDR to help)
EED and loss - spontaneous abortion and resorption

20

24
Q

What should be part of your abortion work up?

A

Clinical signs - return to estrus? unobserved aboriton? blood tinged vaginal discharge
HX, PE, Fetal/placenta exam, maternal serology

25
Q
