Studied were 20 calves of black-and- white bred aged 1.5-2 months divided according to the principle of paired peers into two groups: a control and an experimental. The experimental group was given the probiotic Rumit in the amount of 15 g/head/day during 90 days as a supplement to the basic diet. The data on live weight obtained in the course of the study indicate that the use of the probiotic in feeding calves has led to an increase in gross growth to 74.2 kg, that has provided a 3.8 % reduction in feed costs per unit of output. |
