Nutritional alternatives to mitigate heat stress

During heat stress, the impact of mycotoxin toxicity on animal is higher compared to cold climate. Dr Ram Singh Bibyan

Dietary considerations 1.1 to 1.7 are excellent options. Addition of plant based products hypo thermic medicines are not useful. Of course keeping the outside temperature is the best solution for birds with no sweat glands

Yes, Dear Bertrand, I agree with you and I have also noticed increased feed intake and feed efficiency when birds are fed during cool hours. Dr Ram Singh Bibyan

Some botanicals as spice extracts or Essential oils with some neuro-modulation capacities might also be applied for mitigating heat stress.

This important topic has been on my radar as an animal nutritionist. I added the take-home message from this excellent talk to my list below. Thanks for sharing! Some solutions to mitigate the adverse effects of heat stress: 1. Dietary considerations: 1.1. stimulate feed intake by feeding crumble; feed during the cool hours as much as possible; increase feeding frequency; top-dress the feed using oyster shell meal, molasses, etc.) 1.2. Increase dietary energy so the birds can get their nutrient requirements despite the impaired feed intake 1.3. Increase dietary amino acids level but not the crude protein level 1.4. Increase the levels of sulfur amino acids to help with antioxidant responses during heat stress 1.5. Add vitamin C to the diet 1.6. Adjust Dietary Electrolyte Balance (DEB) to at least 250mEq/kg 1.7. Sodium bicarbonate might help, especially if there is an eggshell problem 2. Proper ventilation strategy to remove the hot air from the barn (example: tunnel ventilation) 3. Proper water treatment (for example, cooling water as much as possible, which can be done by flushing the drinker line and replace with fresh water)

Salicylic acid in the same way can help as anti pyretic in extreme summer conditions and found useful to check heat stroke mortality especially for layer birds

Use of paracetamol @10 mg/kg body weight through drinking water two hours prior to expected peak temperature is useful in maintaining body temperature of broilers. In layers, paracetamol can be used through feed.

I normally advise farmers to feed their birds early in the morning say 6:30 to 7:30am and letter day of afternoon 5 to 6pm and increases the light to 7pm to enable them finish their feed. Fresh water can be served in the afternoon, anything that can add stress to the bords should be avoided
