Heat stress does not start when birds fall dead. It starts when the afternoon shed turns hotter than the bird can lose heat. Panting, wings held away from the body, less feed and more water are the first signs, and by the time deaths begin the flock has already lost weight and eggs. Summer is a few months away, which is the right time to plan. This guide explains what to fix in the shed first and where Coolant and Osmosol from IMN Pyrophos fit, with the label doses of both, the cost for 1,000 L of water and the mistakes to avoid. If you are searching for a heat stress medicine for poultry, start with the dose table below.

What happens to a bird in heat stress?

A bird has no sweat glands. It loses heat by panting, and panting blows off carbon dioxide, which upsets the acid-base balance of the blood. The bird eats less to cut the heat from digestion, drinks more, and loses electrolytes. Growth slows, eggs get thinner shells, and in the worst afternoons birds collapse with heat stroke. A heavy broiler near market weight and a high-producing layer feel it first.

Signs to watch for

  • Open-beak panting and wings held away from the body.
  • Birds crowding at drinkers, wet litter from extra water, less feed eaten in the afternoon.
  • Pale, soft or thin egg shells and a drop in egg numbers in layers.
  • Weight loss or slow weight gain in broilers.
  • Birds lying flat with wings spread, and sudden deaths in the hottest hours.

Fix the shed first

No product replaces cooling. Before any supplement, check these.

  • Ventilation and air speed: open sides, run fans and cooling pads or foggers properly.
  • Cool, clean water: shade the tank and pipes, flush lines in the afternoon, and keep enough drinkers. Sanitize the water (see our water and feed hygiene guide).
  • Feed timing: move feeding to the cool early morning and late evening hours.
  • Stocking density and litter: overcrowding and wet litter add heat and ammonia. See ammonia control in litter.
  • Catching and loading: do it at night or early morning, with water and electrolytes given before.

Coolant and Osmosol: which one when?

Both are given in drinking water, but they are not the same thing and they do not cost the same. Osmosol is the low-cost routine product (1 kg, MRP ₹350). Coolant is the stronger heat stroke product (1 kg, MRP ₹1,050).

  • Osmosol is the simple, lower-cost electrolyte mix with vitamin C and betaine for heat stress management. The label lists sodium bicarbonate, calcium propionate, calcium chloride, sodium chloride, potassium chloride, vitamin C, betaine, natural antioxidants and glucose. Use it for routine hot days, moderate heat stress, and for loading and transport.
  • Coolant is the “ultimate heat stroke solution”, more than an electrolyte. Along with positive DCAD ions, vitamin C, betaine and chromium, the label lists HSP stimulators, aspirin, sodium citrate, probiotics, blood buffers, antioxidants, electrolytes and glucose. Use it when the stress is high, birds are already panting and heat stroke deaths have started or are likely.

Many farms keep Osmosol for the whole hot spell and add Coolant on the worst afternoons. Your vet can decide the exact plan for your flock.

Dose (label)

All doses below are label doses. The label gives no number of days, so confirm the course with your vet or on WhatsApp.

Cost example (calculated from the label doses and the 1 kg prices: Osmosol ₹245, Coolant ₹681). For 1,000 L of drinking water, Osmosol at 1 to 2 g per litre needs 1 to 2 kg, about ₹245 to ₹490; at 3 g per litre 3 kg, about ₹735. Coolant at 1 g per litre needs 1 kg, about ₹681; at 2 g per litre 2 kg, about ₹1,362. Before loading, Osmosol at 20 g per 100 broilers is 200 g for 1,000 broilers, about ₹49. In feed, Coolant at 1 kg per ton of feed adds about ₹681 per ton.

How to give them, step by step

  1. Check the water volume the flock will drink in the hot hours, so you can work out grams per litre.
  2. Weigh the powder on a kitchen scale. Do not use a spoon by guess.
  3. Dissolve it in a small bucket first, then add to the tank or dosing pump.
  4. Give Coolant in the afternoon in fresh, cool water, as the label advises.
  5. Flush and refill the lines so the birds always find cool water.
  6. Note the date, dose and deaths every day so your vet can see what is working.
Coolant by IMN Pyrophos

Heat stroke solution

1 kg ₹681MRP ₹1,050

Osmosol by IMN Pyrophos

Electrolyte for heat stress

Osmosol

Electrolytes with vitamin C and betaine for heat stress management (sodium bicarbonate, calcium propionate, calcium chloride, sodium chloride, potassium chloride, vitamin C, betaine, natural antioxidants, glucose). Keeps DCAD balance positive on hot days.

Dose: 1 to 2 g per litre water in moderate heat stress; 3 g per litre in high stress; 20 g per 100 broilers or 30 g per 100 layers before loading and transport.

Where they fit in a summer plan

What not to do

  • Do not use a supplement instead of ventilation, shade and cool water.
  • Do not change the dose on your own. Use the label doses of Osmosol and Coolant.
  • Do not give hot water from a sun-baked tank. Birds will drink less.
  • Do not mix many products in one tank without advice. Ask on WhatsApp first.
  • Do not handle or load birds in the afternoon heat.

Common mistakes

  • Starting only after deaths begin. Give support from the first hot days.
  • Using the heat stroke dose every day. There is a lower dose for routine hot days.
  • Guessing the water volume. Work out grams per litre properly.
  • Forgetting the drinkers. Few or dirty drinkers undo the best electrolyte.
