Application of plant products as a source of mineral elements in the practice of cattle breeding

The article describes the results of a study of the effect of plant compositions on mineral metabolism and milk production of the cattle. At the "Kartofel'naya Niva Orlovshchiny" 3 groups of animals were formed with 10 animals in each: 1(a) control group contained animals, who received the main diet (MD); 2(a) group - MD + clover seeds (70 g per 1 animal) + liquorice root (60 g per 1 animal); 3(a) group - MD + vegetable spinach (250 g per 1 animal) + basil purple (50 g per 1 animal). At the "Maslovo" 2 groups of animals were formed with 10 animals in each: 1(b) control group contained animals, who received the main diet (MD); 2(b) group - MD + sea-buckthorn fruits (130 g per 1 animal) + hawthorn fruits (40 g per 1 animal). By the end of the experiment in 2(a)gr. there was an increase in the content of potassium, sodium, calcium, phosphorus, iron, copper, zinc in the blood serum by 36.7%; 4.9%; 26%; 12%; 28.9%; 26.5%; 55.3% respectively. In 3(a) gr. there was an increase in the content of potassium, sodium, calcium, phosphorus, iron, copper, zinc in the blood serum by 38%; 2%; 22.6%; 14.8%; 28.2%; 24.4%; 56% respectively. In 2(b) gr. there was an increase in the content of potassium, sodium, calcium, phosphorus, iron, copper, zinc in blood serum by 23.8%; 12%; 32.4%; 22.3%; 51.2%; 27.6%; 61.2% respectively. The average daily milk yield in cows of groups 2(a), 3(a) and 2(b), who received herbal compositions, increased by the end of the experiment by 3.7 kg; 4.3 kg and 3.2 kg respectively.
