Formation of Optimal Thermoenvironment in Cubicles of Cold Cowshed Optimāla temperatūras režīma nodrošināšana, govis turot nesiltinātā kūtī

Assurance of a warm and convenient animal lair is particularly important in cold cowsheds. This is the most important aspect in the environment of the cow, the underestimation of which results in disorders of normal activity of the cow's organism. Investigations show that changing the temperature in cold housing cowshed from -9.4 o C to 11.6 o C, the air inside the cowshed gets by 4.3 o C warmer and by 4.2% drier than the air outside the cowshed, while the microclimate has no negative influence on animal productivity. It is established that cows' rest in cubicles is too short. In the cubicle with a rubber rug, cows lie for 8.7 hours per day, in the cubicle with straw bedding - 7.5 hours per day. In order to create better conditions for cows' rest in the experimental cowshed, the insulation of cattle lair by increasing the straw layer from 2 cm to more than 10 cm is recommended.
