In cattle, nearly 10-30 per cent of lactations may be affected by infertility and reproductive disorders. To attain good fertility or high calving rate both the male and female animals should be well fed and free from diseases.

Many reasons

The causes of infertility are many and can be complex. Infertility or failure to conceive and give birth to a young one can be due to malnutrition, infections, congenital defects, management errors and ovulatory or hormonal imbalances in the female, according to Dr. Cecilia Joseph, Associate Professor,Department of Clinics, Madras Veterinary College,Chennai.

Sexual cycle

Both cows and buffaloes have the sexual cycle (oestrus) once in 18-21 days for 18-24 hours. But in buffaloes, the cycle is silent posing a big problem to the farmers.

Successful heat deduction is possible only when the animals can be properly identified when they come in oestrus (heat), proper maintenance of records and proper training of staff.

The farmers should closely monitor the animals 4-5 times from early morning to late night. Poor heat deduction can cause increased levels of infertility.

Considerable skill is needed to deduct the animals in heat for visible signs. Farmers who maintain good records and spend more time watching the animals obtain better results.
