Goat Pregnancy Toxemia (Ketosis): Symptoms & Emergency Treatment

Pregnancy toxemia (also called ketosis or twin kid disease) is a metabolic emergency that affects does in late pregnancy — usually the last 2 to 4 weeks before kidding. It occurs when the energy demands of the rapidly growing fetuses exceed what the doe can consume, forcing her body to break down fat reserves at a dangerous rate. Without treatment, it is fatal. With early detection and aggressive treatment, many does can be saved.

Why It Happens

In the last 6 weeks of pregnancy, 70% of fetal growth occurs. A doe carrying twins or triplets has an enormous energy demand. At the same time, the growing kids are compressing her rumen, reducing the physical space for food. The doe literally cannot eat enough to meet her energy needs.

When energy intake falls short, the doe's body begins breaking down stored fat for energy. This process produces ketone bodies as a byproduct. In moderate amounts, ketones are a normal alternative fuel. In excessive amounts, they accumulate in the blood, causing a toxic acidosis that damages organs and suppresses appetite further — creating a fatal downward spiral.

Emergency Treatment

1. Propylene glycol drench: 60 mL (2 oz) orally, twice daily. This is the primary treatment — propylene glycol is converted directly to glucose in the liver, providing immediate energy. Continue until the doe is eating normally. Available at farm supply stores (also sold as antifreeze — make sure you buy USP/feed-grade propylene glycol, NOT automotive ethylene glycol, which is fatal).
2. Corn syrup or molasses (if propylene glycol is not available): 60 mL orally as an emergency substitute. Less effective than propylene glycol but provides immediate sugar.
3. Calcium supplementation: Pregnancy toxemia often occurs alongside hypocalcemia (low calcium). Give CMPK (calcium, magnesium, phosphorus, potassium) drench or calcium gluconate orally. Your vet may administer IV calcium.
4. B vitamins: Thiamine (B1) injection supports metabolism and appetite. Vitamin B complex 3 mL subcutaneously daily.
5. Encourage eating: Offer the most palatable feeds available — fresh browse, good alfalfa, warm water with molasses, a small amount of grain. Any calories she voluntarily consumes help.
6. Fluids: Dehydration worsens the condition. Offer warm water with electrolytes. Severely dehydrated does may need subcutaneous or IV fluids from your vet.
7. Reduce stress: Quiet environment, easy access to food and water, no forced movement.

When to induce kidding or C-section

If the doe does not respond to treatment within 24 to 48 hours and she is within 1 to 2 weeks of her due date, your vet may recommend inducing labor (dexamethasone injection) or performing a C-section. Removing the kids eliminates the energy drain and often allows the doe to recover. This decision should be made with your vet based on the doe's condition and gestational age.

Prevention

• Body condition at breeding: Does should be 3.0 to 3.5 BCS at breeding. Not fat (above 4.0) and not thin (below 2.5). Correct body condition before breeding, not during pregnancy.
• Increase energy in last 6 weeks: Gradually increase grain from 0.5 to 1.5 lbs per day for standard breeds (0.25 to 0.75 for NDs) during the last 6 weeks. Feed small meals multiple times per day rather than one large feeding — the compressed rumen cannot handle large meals.
• Quality hay: Switch to alfalfa or alfalfa-grass mix in late pregnancy. Higher energy and protein per pound than grass hay.
• Monitor appetite daily: A pregnant doe that goes off feed in the last month of pregnancy is a red flag. Do not wait to see if she starts eating again — start propylene glycol preventively.
• Know your due dates: You cannot prevent pregnancy toxemia if you do not know when does are due. Accurate breeding records are your first line of defense.
• Ultrasound for kid count: Knowing which does are carrying multiples lets you target the highest-risk animals for extra nutrition and monitoring.
• Exercise: Does that move and browse actively maintain better metabolic function than does confined to small pens. Encourage movement in late pregnancy.

After Recovery

• Continue propylene glycol twice daily until the doe is eating normally and enthusiastically for 48 hours
• Monitor body condition and appetite closely through kidding and into early lactation (energy demand remains high)
• Record the event — does that develop pregnancy toxemia once are at higher risk in subsequent pregnancies. Consider breeding for fewer kids (single-sire breedings with bucks known for smaller litters) or increasing monitoring in future pregnancies.
• Evaluate your feeding program. Pregnancy toxemia is usually preventable with proper nutrition in late pregnancy. If a doe developed it despite good feeding, the kid count may have simply exceeded what nutrition could support.
