Russia: ‘Polar Twilight’ diet for dairy cows

By adding crab meal and lichen fungus in to the diets of dairy cows it is possible to mitigate the negative impact of the lack of sunlight on their health. This was discovered through research carried out by a group of scientists from the Magadan Agricultural University in Russia. Lack of sunlight is a major problem for the dairy industry in the polar regions. The animals experience severe stress, which affects their mood, disturbs the immune system and impairs fertility, the scientists stated.
