Exchanges of proteins, carbohydrates and lipids in cows of schwyz breed of different environmental origin in the zone of the steppe of Ukraine

In the text presented materials of researches of dynamics of the basic biochemical blood parameters of lactating cows of Schwyz breed of Sumy and Austrian environmental origin in the second and third lactation and their descendants in the first lactation. It has been established that the protein, carbohydrate and lipid exchanges in the organism of lactating Schwyz breed cows of different ecological origin pass at a high and balanced level, which is confirmed by the reference values of the total protein at the level of 65.71–83.14 g/l and its fractions – albumin 34.3–35.57 g/l and globulin 30.14–45.29 g/l, urea and urea nitrogen – respectively 3.14–4.59 mmol/l and 6.96–8.76 mg%, creatinine – 104.1–129.86 mmol/l, glucose – 2.22–2.29 mmol/l and lipoproteins – 687.53–859.0 mg% in the serum of blood. It is proved, that cows of Schwyz breed by first lactation, which are grown and exploited in their «own» ecological zone and born from mothers of Austrian and Sumy ecological origin, are characterized by good health and high metabolic processes in their organism. The level of total protein in serum is 71.29–75.86 g/l, albumins and globulins 36.43 and 42.57 g/l, respectively, urea and nitrogen of urea 4.24 mmol/l and 8.10 mg%, creatinine – 108.71–129.57 mmol/l, glucose – 2.27–2.42 mmol/l, lipoproteins – 519.20–782.01 mg%. Normal metabolic processes in the body are provided, first of all, a high and balanced level of feeding, as well as the good adaptation properties of cows Schwyz breed not only in new environmental conditions, but in hard conditions of a large industrial complex of milk production.
