L.A. Zabolotnov, N.A. Tikhonova

The equations were presented developed by the authors for calculation of the heat and en-ergy production in pregnant and lactigenic cows (at the different lactation phases) taking into account the conditions of the environment and the energy, expended by organism on mechanical work.
