The use of plant mixtures in the form of phytocompositions for increasing the adaptive capacity of chicks at different stages of postnatal ontogenesis and for neutralizing the negative effects of post-vaccination phenomena is one of the new promising research avenues. A set of experiments were aimed to determine the dose and develop an application schedule for the phytocomposition Vitastimul in order to improve chicken viability and productivity on the background of post-vaccination stress. The experiments were conducted on 10-120 days old chicks and 150-300 days old laying hens, which were given with drinking water the preparation Vitastimul in the following doses: a) 0.1 ml/kg, b) 0.5 ml/kg and c) 1.0 ml/kg of the body weight. At the end of the investigation period a significant weight gain was recorded in both control and experimental groups, however this process quantitatively prevailed in chicks that received the phytocomposition in the dose of 0,5 ml/kg and 1,0 ml/kg. Hen survival rate during egg laying period was greater in the group with 0.5 ml/kg (97.9 %). The greatest number of eggs during the testing period, with a difference of 5% compared to the control was also obtained in the group which was administered the phytocomposition Vitastimul in a dose of 0.5 ml/kg.
