  Vitamin C, along with Vit. A and E; also Zn.

  Preferably vitamin C beyond sodium bicarbonate.

  I would use natural betaine as the first choice additive for heat stress owing to its well documented role as an osmolyte, and comparatively economical inclusion when its choline and methionine sparing capabilities are considered.

  Ascorbic acid has never shown an effect
  on production or egg quelity in NW Mexico, than, the choice has been sodium bicarbonate and salicylic acid for layers in summer in Hermosillo.

  Above those two additives i would prefer betaine, either natural or as betaine.hydrochloride.
  As natural osmolyte, choline- and methionine-sparing methyldonor it is very (cost)effective against heat stress.

  Back here in Indonesia, Vit C did not gave any clear effect against Heat stress.
  Usually in Indonesia we prefer to used combination between Vit C and fan. actually fan had more effect than Vit C.
  But can anyone tell me benefit of Tryptophan to control stress ?

  @ Gustavo Cordova
  Why would you want to spare choline through the addition of betaine (cost-wise)?

  My answer to Judith :
  The question is what to give against Heat Stress. By using betaine against heat stress you dose enough to replace as side effect part or all of the otherwise added cholinechloride.

  The best and economic remedy for broilers-heat stress/mortality is: no feed for all the day long ( from 7,30 a.m. to 7,30 p.m.)... and fresh water!! C and betaine on top in feeds.

  I prefere to use NaHco3 plus chelated Cr. both of them have a grate effect on feed intake,heat tolerance and mortality of poultry with blood and hormonal mechanism.
