Ovarian Cysts in Cows & Buffaloes: Causes & Treatment

Quick answer

Ovarian cysts (cystic ovarian disease) are fluid-filled structures on the ovary that fail to ovulate and upset the hormone cycle, so a cow or buffalo either comes into heat again and again at short, irregular intervals, shows intense continuous heat (nymphomania), or stops showing heat altogether. They are a leading cause of repeat breeding and long calving intervals in high-yielding dairy animals. Diagnosis and treatment need a veterinarian (usually hormonal therapy), while good transition-period nutrition, body condition and mineral balance help prevent them.

What are ovarian cysts?

A cyst is a follicle that grows larger than normal (usually over 2.5 cm) but does not release an egg or form a normal corpus luteum, and persists on the ovary. There are two main types: follicular cysts (thin-walled, often causing frequent or intense heat) and luteal cysts (thick-walled, often causing no heat). Both interrupt the normal 21-day cycle and prevent conception.

Signs to watch for

  • Repeated short or irregular heats and failure to conceive after several inseminations — see repeat breeding in cattle
  • Intense, frequent or continuous heat (nymphomania), bellowing and mounting other animals
  • Or the opposite — no visible heat for a long time; see anoestrus and silent heat
  • Slackening of pelvic ligaments and a raised tail head in long-standing cases

Why ovarian cysts develop

Cysts are most common in the first 60 days after calving in high-yielding cows and buffaloes. Risk factors include negative energy balance in early lactation, a sharp drop in body condition, mineral and trace-element imbalance (phosphorus, selenium and others), heat stress, and uterine infections such as metritis. High milk yield and genetics also play a role.

Diagnosis and treatment

A veterinarian confirms cysts by rectal palpation or ultrasound and chooses the treatment based on the cyst type — usually hormonal therapy (GnRH, hCG, or a prostaglandin/progesterone-based protocol such as Ovsynch). Many early cysts also resolve on their own. Never use hormones without veterinary advice, as the wrong protocol can delay recovery.

Supportive management and nutrition

Alongside veterinary treatment, correcting nutrition and uterine health improves results. Balance energy in early lactation, restore body condition, and supply adequate minerals and trace elements with a daily mineral mixture such as Cattle Remedies Verymin. Where cysts follow retained placenta or uterine infection, herbal uterine tonics support cleansing and reproductive tone — see Uterotone 3-in-1 and Uterotone Liquid, and our guide to the best cattle uterine tonic in India.

Prevention

  • Manage the transition period to avoid severe negative energy balance
  • Keep a steady body condition score — avoid over-fat or over-thin animals at calving
  • Supply balanced minerals and trace elements all year round
  • Treat uterine infections promptly and maintain good calving hygiene
  • Keep heat-detection and breeding records so cysts are caught and treated early

Frequently asked questions

Why does my cow come into heat again and again but not conceive?

Repeated short or irregular heats with failed conception can be caused by a follicular ovarian cyst. Have a veterinarian examine the ovaries; most cysts respond well to the right hormonal treatment.

Can ovarian cysts in cattle be cured?

Yes. Many cysts resolve on their own or respond to veterinary hormonal therapy, after which the animal returns to normal cycling and can conceive. Early detection and good nutrition improve the outcome.

How do I prevent ovarian cysts?

Manage the transition period and energy balance, keep body condition steady, supply balanced minerals and trace elements, and treat uterine infections promptly. Good records help you spot problems early.
