The Unspoken Reality of Heat Stress in India

Chickens are homeotherms, meaning they rely on a narrow ideal ambient temperature—known as the Thermoneutral Zone (TNZ), which is between 18°C and 22°C. Once the effective temperature inside the shed crosses 26°C, a broiler’s body can no longer dissipate metabolic heat normally, and heat stress begins.

Here is why heat stress occurs year-round in Indian farms:

High Humidity Multipliers (Monsoon): In high-humidity conditions (60%+), even a mild 28°C day feels like 35°C to a bird. Because chickens lack sweat glands, they rely on panting (evaporative cooling) to release heat. High humidity stops this evaporative process, trapping heat inside the bird.
Monsoon/Winter Curtain Closures: To protect chicks from cold winds or rain, farmers close side curtains in open-sided sheds. This traps metabolic heat, carbon dioxide, and body moisture generated by high-density broilers, rapidly pushing internal shed temperatures well above the TNZ.
Fast-Growing Genetics: Modern broilers generate significant internal body heat due to rapid muscle growth. As birds reach market weight (above 1.8 kg), their dense feathering makes it difficult to vent this metabolic heat, even on cool days.

What Happens Inside the Bird During Heat Stress?

When a broiler struggles with heat, its body diverts energy away from growth and digestion:

Severe FCR Drop: For every 1°C increase above 30°C, feed intake drops significantly.
Gut Wall Breakdown: Heat stress reduces blood flow to the internal organs, damaging the intestinal lining. This causes “leaky gut,” allowing harmful bacteria like E. coli to enter the bloodstream.
Oxidative Stress & Mortality: Panting causes rapid loss of body moisture and triggers oxidative stress, suppressing the bird’s immune system and leading to sudden death.

The Modern Solution: Protecting Your Flock from the Inside Out

While fans, foggers, and roof sprinklers help manage environmental heat, they cannot stop internal metabolic heat stress. To protect bird growth year-round, you need a nutritional strategy that improves thermal tolerance from within.

This is where MaxiGAIN provides a distinct advantage.

MaxiGAIN is a scientifically formulated, natural essential oil blend specifically designed to combat heat stress, support gut integrity, and maintain high growth performance:

Natural Heat Stress Relief: Formulated with bioactive compounds like Capsaicin and Trans-Resveratrol, MaxiGAIN reduces internal inflammation, lowers oxidative stress, and helps birds regulate body temperature under high-heat conditions.
Protects Gut Integrity: Active ingredients like Carvacrol and Cinnamaldehyde shield the gut wall from structural damage during heat stress, ensuring optimal nutrient absorption even when feed intake drops.
Sustained FCR & Growth: By keeping the digestive system running smoothly without straining the bird’s energy reserves, MaxiGAIN ensures your flock hits target market weights on schedule, season after season.

Protect Your Farm’s Bottom Line Year-Round

Heat stress does not wait for summer, and your nutrition strategy shouldn’t either. By incorporating MaxiGAIN into your feed at just 0.5 kg to 1 kg per ton, you give your broilers the natural internal defense needed to maintain optimum FCR, high immunity, and maximum weight gain in any season.
