Abstract

The article presents the results of scientific and economic experience in determining the comparative effectiveness of the use of feed products based on safflower cake in cow feeding diets. The research was carried out in Uchkhoz Iyulskoye of the Izhevsk State Agricultural Academy (Votkinsky district, Udmurt Republic, Russia). Animals were selected into groups according to the principle of pairs of analogs. The influence on milk productivity, composition, and technological properties of cow milk was studied. The animals of the control group received the main diet, which included sunflower cake. One kg of sunflower cake was replaced with safflower cake for cows of the first experimental group, and with safflower cake with propylene glycol in the second experimental group. The replacement of sunflower cake with safflower cake and a feed product consisting of safflower cake and propylene glycol in the amount of 1 kg in the diets of highly productive cows contributes to an increase in milk productivity by 2.63 and 1.96 kg. The best effect is obtained when using safflower cake in its pure form. The positive dynamics of improving the quality characteristics of milk, in particular the mass fraction of fat, were noted. The introduction of safflower cake into the diet improves the technological properties of milk: the duration of rennet coagulation is reduced; the dynamics of increasing the diameter and mass of casein micelles is traced.
