Ewes can experience several pregnancy problems including pregnancy toxemia, hypocalcemia (milk fever), and hypomagnesaemia (grass staggers). Pregnancy toxemia occurs when ewes do not receive enough nutrition in the last weeks of pregnancy. Hypocalcemia is caused by stress lowering blood calcium levels in late pregnancy. Hypomagnesaemia results from ewes consuming fast-growing spring grass low in magnesium. Treatment for these conditions involves calcium or magnesium supplementation through intravenous or subcutaneous injections.

3. Ewe 3
“ The female of the sheep especially when it
fully mature”.
• A member of a people of Togo and Ghana, in
western Africa, the Kwa language spoken by
the Ewe people.

5. Puberty 5
• Ewes generally reach Puberty at six to
eight months of age .
• Puberty is when a ewe reaches sexual
maturity and exhibits estrus (heat) for the first
time.
• The age of puberty is influenced by
breed, genetic selection, body size,
nutrition, and season of birth.

6. Pregnancy 6
The average gestation length in sheep varies
from 142 to 152 days.
• The average is 147 days.
• There are breed differences in gestation
length.

7. Pragnancy problems 7
01. Pregnancy toxaemia
02. Hypocalcaemia
03. Hypomagnesaemia

8. 01.Pregnancy toxaemia 8
• ketosis, pregnancy toxemia
• Pregnancy toxaemia occurs when low levels of
glucose in the blood, damage the brain and
result in dehydration, kidney failure and
potentially death.
• It usually occurs in the last weeks of
pregnancy.

9. Causes 9
not receive enough nutrition.
• In Western Australia, autumn is a precarious time
for ewes dry feed is minimal and the
pregnant ewe’s nutritional needs are increasing,
making her susceptible to pregnancy toxaemia.

10. Symptoms 10
• standing apart from the flock
• not grazing
• not coming to the trough at feeding time.

11. Treatment 11
• Propylene glycol can be given orally that acts
as a precursor to glucose
• administering IV dextrose

12. 02. Hypocalcaemia 12
(Also known as Milk Fever)
• It can occur in late pregnancy.
• The condition can be induced by some form of
stress with her normal metabolism
low blood calcium.

13. Symptoms 13
• in the early stages the ewe difficult
walk
• Her pupils will be dilated, As the condition
progresses, she will become recumbent, or
with her chin on the ground unable to raise
her head and she may start to produce a
frothy fluid from her mouth and nose.

14. Diagnosis 14
• Because a significant Ca albumin

15. Treatment 15
• administered as calcium borogluconate IV
(50–150 mL of a 23% solution)

16. 03. Hypomagnesaemia 16
(Also known as Grass Staggers)
• Fast-growing spring grass is often very low in
magnesium, especially if it has been heavily
fertilised with nitrogen and potash fertiliser,
resulting in low blood magnesium in the ewe

17. Symptoms 17
• animals will appear over-alert
• if left untreated the condition progresses
quickly,
• causing excitability and spasms, or
convulsions, leading to collapse and death in a
few hours

18. Treatment 18
.
• 1. Slow intravenous injection of calcium
borogluconate and magnesium sulphate
• 2. Further subcutaneous injection of a
solution containing a higher concentration of
magnesium.
