Heat stress control

Steadier poultry performance in a warming climate.

Heat stress is a major, climate-driven constraint on poultry production. It occurs when birds cannot dissipate enough body heat, triggering physiological and metabolic changes that reduce feed intake, growth, egg production and shell quality while increasing disease risk and mortality.

18–24 °C

is the ideal temperature range for laying hens.

30 °C

is where hens already cut their feed intake, leading to smaller eggs and eventually lower egg production.

Above 38 °C

birds can only lose heat through severe panting, which upsets their acid-base balance and lowers the blood calcium needed for strong shells, so more eggs have thin shells.

Why heat stress control matters in poultry

In broilers and layers, heat stress disrupts metabolic homeostasis and gut integrity, raises oxidative stress and inflammation, and shifts energy away from production toward cooling and survival.

The result is slower growth, fewer and smaller eggs, thinner shells, poorer feed efficiency and more variable flocks, plus higher treatment costs and losses during hot periods.

How we support heat stress resilience in poultry, naturally

Our all-natural portfolio helps broilers and layers maintain performance and welfare under heat load by supporting antioxidant defences, gut barrier function, immune balance and efficient nutrient use.

Fitogeniki

Bioactive plant compounds with antioxidant and anti-inflammatory actions that reinforce cellular defences, protect the gut, and improve thermotolerance and feed efficiency under heat load.

Pre- and probiotics

Beneficial microbes and fibres that stabilise the gut microbiome, strengthen intestinal barrier integrity, and modulate stress and immune responses, key pathways impaired by heat stress.

Vitamin blends

Antioxidant and metabolic vitamins (such as A, C and E and supporting micronutrients) that reduce oxidative damage, support immunity, and help maintain intake, production and product quality during hot weather.

What farmers gain

When heat stress is better controlled with these natural tools, poultry producers typically see:

More stable feed intake and growth

Less depression in daily gain and feed conversion during hot spells, and more consistent weights in broilers.
Better egg production and shell quality

Improved laying rate and shell quality in layers under thermal stress.
Lower mortality and treatment costs

Fewer heat-related deaths, fewer secondary infections, and less reliance on therapeutic interventions during peak heat.
Improved welfare and resilience

Calmer birds, better gut health, and stronger immune and antioxidant status, helping flocks cope with recurring hot periods.
More predictable profitability

Smaller production dips in summer, more uniform flocks, and fewer downgrades or losses when temperatures rise.

By supporting the gut–immune–antioxidant axis with natural solutions for poultry, our products help you turn heat stress control into measurable return: steadier performance, lower losses and more reliable output in a warming climate.
