Usage effectiveness of phytopreparation at needles base in broiler rearing

The results have been given in the paper on usage of new phytopreparation at needles base in broiler rearing. Its positive effect has been established on blood hematologic and biochemical parameters and on broiler im- munity and production. The best dose is 30 g/kg feed since third till 42th rearing days and 40 g/kg feed since 11th till 42th days. This scheme using effects positively on poultry physiologic condition and increases blood hemoglobin con- tent by 35.8%, total protein by 29.5%, albumins and globulins by 16.2 and 39.7% respectively. Phytopreparation pro- motes post vaccination antibodies development against Newcastle disease virus increasing average antibodies titer by 0.4 log2, promotes poultry body weight increasing by 8.0% and lowering feed costs per 1 kg body weight increas- ing by 7.6%.
