Malaysia Livestock Sector Faces Rising Heat, Haze and Water Stress

KUALA LUMPUR, September 30, 2026: Malaysia’s livestock sector is facing a combination of heat stress, haze, water shortages and higher feed costs, with farmers reporting weaker egg, poultry and milk production in some operations. The emerging situation highlights the growing intersection between climate conditions, animal health and farm economics.

Farmers and industry representatives report that prolonged hot weather has increased the difficulty of maintaining animal productivity, particularly for smaller operations with limited access to climate-controlled housing and veterinary support.

Poultry producers have reported slower growth and, in some cases, increased mortality among laying hens, while dairy producers have experienced reductions in milk output. However, veterinarians caution that the contribution of haze and particulate pollution cannot be separated easily from heat, water availability, feed, housing and disease.

For poultry producers, ventilation and cooling have become important operational investments. Small-scale farmers have installed fans and misting systems, while some operators are investing in more extensive ventilation, solar power and automated cooling infrastructure.

The economic impact can be significant for smaller producers. Dairy farmer Ari Ramash Supramaniam reported a reduction of approximately 4–6 litres of milk per day from five cows, while additional expenditure on grass, molasses, water and feed has been required to maintain animal condition during the heat.

Broiler producers have also reported that some birds required up to an additional week to reach normal market weight, according to industry representatives. At the same time, the Malaysian Federation of Livestock Farmers’ Associations said it had not received reports of increased poultry mortality directly attributable to the current haze episode.

The respiratory implications of particulate pollution are an additional concern. A modelling study cited in current reporting projected that three days of exposure to PM2.5 concentrations of 150 µg/m³ could reduce average daily weight gain in broilers by approximately 5.2%. Researchers stressed that these were modelled predictions rather than direct measurements of current Malaysian farm losses.

Strategic Industry Implications

The episode illustrates how climate resilience is becoming part of mainstream animal-health management. Ventilation, cooling, clean drinking water, feed optimisation, mineral supplementation, environmental monitoring and veterinary oversight increasingly form an integrated production-health system.

For animal-health companies, the development could expand demand for heat-stress management products, environmental monitoring, nutritional interventions, ventilation technologies, water-management systems and preventive veterinary services.

Analyst View

The key issue is not haze alone but the cumulative physiological and economic burden created when heat, air quality, water and feed pressures occur simultaneously. For livestock producers, climate-adaptive housing and preventive animal-health protocols are becoming increasingly important components of production resilience.
