Description
Summary:The results of studies on the influence of the genotype of red-mottled cows of Holstein breed on the chemical composition and technological properties of milk are presented. In a herd of cows of the red-mottled breed of the cattle of "Roschinskoye", for the assessment of the chemical composition and technological properties of milk depending on the genotype of the animals by the method of pairs-analogs, 3 groups of full-aged cows were formed: 1/2, 5/8 and 3/4-blood on KPG. The selected milk on the farm was analyzed in the laboratory of Voronezh State Agricultural University named after the Emperor Peter the Great. For a more complete picture of the qualitative indicators of the milk obtained from the full-aged cows with blood 1/2, 5/8 and 3/4 KPG, butter was also produced. As a result of the production of a trial batch of dairy products, the technological properties of the milk during processing, as well as oil and physical, chemical and organoleptic characteristics of the finished product, were determined. On the basis of the conducted research, the recommendations on improvement of the red-mottled dairy breed of the cattle were given.
