How do sheep prevent pregnancy Toxaemia?

Ewes or does should not enter the last 6 wk of gestation with a BCS <2.5; this can be prevented by good feeding management, eg, adequate feeder space for pregnant animals, sorting (based on BCS, fetal numbers, and animal size), forage analysis (for energy, digestible fiber, and protein levels), and ration formulation.

How do ewes prevent ketosis?

To prevent ketosis in sheep, it is important to identify the animals carrying twins or triplets, separate them and provide them with a diet that will meet their increased energy demands. The level of nutrition should be increased gradually over the last 6 weeks of sheep gestation.

The symptoms of milk fever and ketosis are similar, though milk fever seems to develop more suddenly. The differential diagnosis is the ewe’s response to calcium therapy.

What is hypocalcemia in sheep?

Hypocalcaemia is an abnormally low level of blood calcium. On farms it is mostly seen in cows prior to and soon after calving. In sheep it is usually seen in ewes in late pregnancy but can be seen in all classes of animals.
