A recent study published in the 'Journal of Dairy Science' found that dry cows exposed to heat stress produced up to 8 litres less milk per day in their next lactation compared to cows kept in a cooled environment.
The dry period is one of the most critical stages in a dairy cow's production cycle, prepairing for her next lactation by:
โ
Rebuilding the mammary gland
โ
Developing new milk producing cells
โ
Preparing the udder development for high yields
When cows experience heat stress, their bodies prioritise keeping cool. Blood flow is redirected towards the skin, reducing support to the mammary gland. This can lead to:
๐น Less oxygen reaching the udder
๐นReduced nutrient supply for mammary development
๐นAltered Hormone function
๐นLower milk producing capacity in the next lactation
