Abstract
The results of the study on the effect of new microbial preparations on the dynamics of the absolute weight and average daily gain of geese are presented. In the scientific experiment, probiotics Vetom 20.76 based on the predatory fungus Arthrobotrys oligospora and Vetom 1 on the basis of live spore-forming bacteria of the Bacillus subtilis DSM 32424 strain, which have anthelmintic, antiviral and antifungal effects, were used. One control and four experimental groups of 10 goslings each at the age of 1 month were formed according to the principle of analog pairs. The goslings of the experimental groups received Vetom 20.76 in various dosages: young birds of the 1st experimental group – 0.5 μl/kg of live body weight, the 2nd – 1 μl/kg, the 3rd – 2 μl/kg. Goslings of the 4th experimental group were given Vetom 1 at a dose of 50 mg/kg of live body weight. Both drugs were given in the morning with water, once a day for 30 days. These drugs were not prescribed to geese of the control group. It was established that Preparations Vetom 20.76 in doses of 0.5; 1 and 2 μl/ kg of body weight and Vetom 1 at a dose of 50 mg/kg of body weight have a growth-stimulating effect when given to goslings for 30 days. The growth rate of the experimental birds depended on the dose of the drugs used. Optimal results were obtained with the use of Vetom 20.76 at a dose of 2 μl/ kg of body weight and Vetom 1 at a dose of 50 mg/kg of body weight once a day for 30 days. The average daily gain in live weight of the experimental geese increased in the 3d and 4th experimental groups by 5.24 and 20.60% in the first 15 days of the experiment and by 24.8 and 44.64% during the aftereffect of the drug.
