Impact of Heat Stress on Cattle

• Heat stress reduces natural mating behavior,
  leading to a decline in the readiness to mate
  among female cattle.
• Conception rates drop significantly during hot
  summer months, with up to a 30 reduction.
• Lactating dairy cows are more sensitive to heat
  stress than non-lactating cows.
• High-yield cows are particularly affected due to
  the relationship between milk production and
  heat.
• Heat stress poses a challenge to sustaining milk
  production, impacting domestic demand and
  potentially reducing per capita consumption.
• It directly reduces milk production in the dairy
  sector and indirectly affects feed and water
  availability for cattle.

Issues Faced by Dairy Farmers

• Government policies, such as sex-sorted semen
  production, may unintentionally decrease the male
  cattle population.
• Growing female cattle population could impact the
  utility of male cattle in agriculture.
• Disposal of unproductive female animals is
  challenging due to anti-slaughter rules in many
  states.

  country, with 221.06 million tonnes of milk
