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.

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.

Pragnancy problems 7

01. Pregnancy toxaemia 02. Hypocalcaemia 03. Hypomagnesaemia

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.

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.

Symptoms 10

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

Treatment 11

• Propylene glycol can be given orally that acts as a precursor to glucose

• administering IV dextrose

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.

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.

Diagnosis 14

• Because a significant Ca albumin

Treatment 15

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

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

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

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.
