I am doing research on how to reduce the heat stress of dairy cows by feed additive, so need your suggestions thanks
some vitamins were studied for their action on the animal physiology to cope with heat stress. The decreased feed intake observed under hot conditions also has repercussions on the intake of vitamins, which play an important role on immune function and performance. In order to reduce the negative effects of environmental stress, vitamins A, C and E are generally used in ‘hot diets’, particularly in poultry diet, because of their anti-stress effects, and also because their concentrations are lower during heat stress. Also, Fungal culture and plant extracts may exert a positive action in rumen metabolism as well as in regulation of body temperature. Among fungal culture, yeast (Saccharomyces cerevisiae) was widely studied. Supplementation of live yeast could improve nutrient digestibility and feed efficiency.
Vitamin A, C and E are highly recommended during hot days.

No one fix to Heat Stress! other managemental aspects come handy however, in the space of using additives to alleviate this challenge; highly recommend the technology by Diamond V called NutriTek https://www.diamondv.com/products/species-specific/nutritek/
Lower roughage content may help:
Adin, G., et al. "Heat production, eating behavior and milk yield of lactating cows fed two rations differing in roughage content and digestibility under heat load conditions." Livestock Science 119.1-3 (2008): 145-153.
Dear Ali Mujtaba Shah
If specifically, we talk about only heat stress there are lots of feed additives that can be used to reduce heat stress as some of the scholars already mentioned. Heat stress is one of the seasonal effects which not only causes productive loss but also economic losses to a producer. Well, these days I read lots of research studies that pay attention to plant-based like Small peptides It can reduce the heat stress effect as well as improve animal health & productive performance. some of the peoples consider as additive while others are using an alternative source of protein to replace animal-sourced protein.
Dear Ali Mujtaba Shah
Rumen protected Niacin and choline may be helpful in alleviating heat stress in dairy cows.
Hello Ali,
Antacids and specially sodium bicarbonate help with heat stress, improving the CO2 gas turnover in the dairy cow. Easy, relatively cheap, proven.
Hope that helps!
Kind regards

Try out 2 ways: 1) heat-treated SMB (HTSBM), as rumen by-pass protein source; 2) HTSBM+live yeast+protected niacin.
Niacin of Vitamin B3 alleviates heat stress by increasing evaporative heat loss from an animal's body and reducing heat effects at the cell level. Moreover, phytonutrients can beat heat with phytomolecules consisting of capsicum oleoresin, cinnamaldehyde and eugenol.
Thank you very much Nila Nanette SUERO Revilla for your answer and help
