Heat Stress

Published: July 26, 2021
Summary
Thermal stress happens when the animal leaves its thermal comfort zone, it means neither too cold nor too hot, let's say it feels good. In both of the cases, the stress due to heat and cold, the problem itself is not the temperature alone, but its relation to relative humidity level. The differences in sensitivity for each species must be taken into account. Cows cope better with high tem...

Dear Viorel Marculescu,

Several compounds as methol or eucaliptol, induce the cool perception, it is due to the capacity of activation of the so-called cold receptors, particularly those from TRP family. In the case of essential oils, the ion channel TRPM8 (this can be found mainly on skin and oral cavity) is activated in the same way as cold is doing: increasing or reducing the ion exchange.
Best regards,
Ewa.

Essential oil like peppermint oil or eucalyptus do possess to treat systemic dyspepsia by relieving pain cropped up in GI tract through IBS though they have little effect to address abdominal colic like covered by Simithicone. Hence your declaration demands further study to draw a conclusion on their true efficacy. Above all, they are from extraction from herbal leaf only and more prudent to obtain relief from pain superficially especially on muscles and ligaments.

Practically, I learned that birds that are on deep litter system enjoy more during hot season that those in the battery cage system.

This is evidently proven because the saw dust on the floor conserves moisture which dramatically birds do lie upon.

Nothing can be better than controlling the house temperature Spray water with foggers in dry weather. Add airmovement with fans if weather is also humid. Tunnel ventilation with cooling pads and exhausts in a house whose sides are closed.

Spending a lot of money to reverse heat stress impact not seems wise, instead we should consider the root cause of heat stress and should work in minimizing the stress triggers. But different tools can be applied according to the house facilities and environmental conditions. Reduce the density of birds/sq meter, Provide fresh and cool water during warm hours, you can also use sand in warm season, birds setting in Sand dissipate body heat to sand and feel comfortable. Fans , cooling fads, and a number of practices can be exercised, instead of depending and spending on essential oile and other medicine. A good and successful farmer is the one who can manage the problem not towait and compete the consequences of the problem.
