Livestock :
]The humidity expected to be higher from 13.04.2015, along with high temperature will cause more
stress to the animals. This will be avoided by providing good ventilation in the animal shed.
Avoid grazing of sheep and goat near lake and ponds to reduce fluke infestation.
During day time farmers are advised to sprinkle water to high yielding dairy cows 2 or 3 time to reduce
heat stress.
Due to increase in day temperature animals should not be allowed for grazing during hot part of the day,
provide cool drinking water and shade to the animals to reduce heat stress.
Farmers are advised to withdraw the feed for the poultry during hot part of the day to avoid heat stroke
and provide cool drinking water.
