Rising global temperatures are disrupting dairy and beef production, driving feed costs higher, and increasing disease risks in poultry systems worldwide.
Global livestock systems are entering a critical stress phase as rising temperatures continue to disrupt animal productivity, feed supply chains, and overall meat and dairy output across multiple regions.
According to recent international assessments, dairy cattle and beef herds are increasingly suffering from heat stress, leading to reduced milk yield, slower growth rates, and declining reproductive performance. In extreme heat zones, livestock mortality risks are also rising, particularly where cooling infrastructure and veterinary support are limited.
At the same time, feed cost volatility is adding further pressure on meat production systems, forcing producers to adjust herd sizes and production cycles in response to unpredictable input prices.
Experts highlight that while all livestock sectors are affected, poultry remains the fastest-growing global protein source due to its affordability and efficiency. However, it is also emerging as one of the most vulnerable sectors, with higher sensitivity to heat stress, dense farming systems, and increased risk of infectious disease outbreaks.
Veterinary analysts warn that without improved climate adaptation strategies—such as better housing systems, heat mitigation technologies, and stronger disease surveillance—the productivity gap in global livestock systems is likely to widen further in the coming years.
The combined impact of climate stress and economic pressure is reshaping global food production patterns, making livestock resilience a central concern for food security planners worldwide.
