Cooling is the predominant strategy to alleviate the effects of heat stress on dairy cows

Zvi Roth

Summary: Reduced reproductive performance of lactating cows during the summer is mainly due to intense genetic selection for high milk production, which puts a heavy burden on the thermoregulatory mechanism. Efforts have been made to understand the mechanism by which heat stress affects fertility. Data so far suggests that the impact of thermal stress on the female reproductive tract is multifactorial. Based on this understanding, new strategies to mitigate the effects of heat stress have been developed. Cooling is the dominant strategy used to alleviate the effects of heat stress, although it cannot completely eliminate the decline in reproduction. Additional hormonal treatments are suggested to improve reproductive performance during the summer. Comprehensive reproductive management combining multiple strategies is suggested to be more beneficial.

Thermal Mechanisms Preventing or Favoring Multiple Ovulations in Dairy Cattle

Fabio De Rensis et al.

Summary: While cows are typically monovular, the incidence of dizygous twin births has risen significantly in recent years alongside increasing milk production. Multiple pregnancies are undesirable as they negatively impact cow health and herd economy. Studies suggest that thermal mechanisms may play a role in preventing or favoring multiple ovulations leading to twinning.

Cervix-rectum temperature differential at the time of insemination is correlated with the potential for pregnancy in dairy cows

Fernando Lopez-Gatius et al.

Summary: The study suggests that temperature differentials between the caudal cervical canal and rectum post-insemination may be associated with the likelihood of pregnancy in lactating dairy cows. Under heat stress conditions, temperature gradients changed significantly in ovulating cows from the time of insemination to 7 days post-insemination, but not in non-ovulating cows.
