Clostridial Diseases of Sheep and Cattle

Blackleg, pulpy kidney (enterotoxaemia), black disease, tetanus, and malignant oedema are common causes of death in unvaccinated sheep and cattle. Other animals, particularly goats, are also susceptible.

Seen mostly in lactating beef cows in winter and early spring, grass tetany can lead to the death of most clinically affected animals. The disorder is associated with low levels of magnesium in the blood.

Managing Fresh Cows in the Shed

One of the most important things about milking fresh cows is to ensure that the milk is suitable to go in the vat.

The main roundworm of cattle is Ostertagia ostertagi, known commonly as the brown stomach worm. Control of ostertagia will incidentally control other roundworms of lesser importance.

Raising Poddy Lambs

Orphan lambs may arise after the death of the ewe or due to abandonment or rejection, especially by first time or maiden ewes and those with multiple lambs. Raising orphan or poddy lambs by hand is a lot of hard work, but the results are well worth it.

Milk Fever - Hypocalcaemia

Milk fever is a disorder mainly of dairy cows close to calving. Between 3% and 10% of cows in dairying districts are affected each year, with much higher percentages occurring on some properties.

With summer's arrival, now is the time to start thinking about summer drenching of cattle as part of your strategic roundworm control program.

Leptospirosis In Cattle and Humans

Leptospirosis is an important public health and animal health issue. It is an infectious disease of cattle, other livestock and humans.

Sheep Body Lice - Itchy Sheep

Sheep body lice (Bovicola ovis) are biting insects that cause affected animals to become itchy. Lice are a common problem, but most importantly are controllable, eradicable and preventable.

Acetonaemia (Ketosis) of Dairy Cows

A very distinct problem for dairy cows is the disease of ketosis (or acetonaemia). The occurrence of this disease in dairy cows is related to an increased demand for glucose by the animal.
