Night Milk - Assessing the reliability and economic benefit

Melatonin is the hormone contained in milk that helps control sleep and wake cycles and is produced naturally by the cow in response to darkness. Two dairy farmers in the Bridgend area are involved in an EIP project which could potentially find the best milking system to increase Melatonin in their herds’ milk.  

Both farms are 3 times a day dairy systems that are milking their entire herd at 8 hour intervals. At present the milk from the three milkings is pooled together, but in this 13-month project the milk produced during daylight and darkness will be sampled separately.

The project will determine whether there is enough Melatonin in the night milk to brand it for its sleep-inducing properties.
