Резюме: Twelve suckling Simental calves at the age of 8 days were allocated into two groups. The control calves
were fed on 4 kg milk per head daily, concentrate mixture and alfalfa hay ad libitum. The experimental
animals were fed on the same ration but milk was supplemented with a mixture of dry plant extract of
Cichoria intybus, Cotinus coggygria and Tanacetum vulgare at a dose of 500 mg per head daily.
During the 62-day-long experimental period the experimental calves had a slightly higher average daily
intake of dry matter, concentrate mixture and alfalfa hay (P>0.05) and a higher daily weight gain (P>0.05)
than the control calves - 629.42 g versus 516.48 g respectively, which resulted in lower energy and protein
expenses per 1 kg of weight gain.
