| Cystic Ovaries
Theis year cystic ovaries have been occurring very commonly, and have
been one of the most important causes of cows being presented to the vet
for not being seen bulling
What are cystic ovaries
A cystic ovary is an ovary with a large (usually greater than 2cm),
persistent (usually for more than 10 days) fluid-filled structure.
Cysts are often divided into two groups (luteal and follicular), based
on production of progesterone and appearance. However, there is a vast
amount of overlap between the two types and it is probably best to treat
them just as cystic ovaries.

Clinical Signs
Cows with cystics ovaries usually have abnormal oestrus cycles;
persistent oestrus, shortened oestrus intervals or failure to cycle
(anoestrus). Anoestrus is by far the most common sign.
Persistent bulling behaviour, or nymphomania, is by far the least common clinical sign associated with cystic ovaries.
Diagnosis
* Best done by ultrasound examination by a veterinarian
Treatment
* Early prompt treatment is important as most cysts will not resolve on their own.
* A wide range of products have been used to treat cystic ovaries.
Progesterone, prostaglandins and gonadotrophin-releasing hormones are
the most commonly used products
Prevention
We do not fully understand the causes of ovarian cysts, which means that
there are no specific prevention regimes. However energy deficiency is a
major factor, and reducing the depth and length of the period of
negative energy balance after calving, will significantly reduce the
incidence of cystic ovaries
This can be achieved by:
1. Ensuring cows calve with a condition score between 2 and 3
2. Correct formulation of the ration
3. Maximising dry matter intake
4. Minimising metabolic disease
5. Maximising the care of the cow at and just after calving
