MICROBIOLOGICAL PREPARATIONS – INNOVATIVE METHOD OF INTENSIFICATION GROWTH OF CHICKEN-BROILERS
The use of probiotics is widespread in the poultry industry. The probiotics have positive effects on many organ and systems. The purpose of this work – studying of effect of probiotics on the growth and development of chicken-broilers. For the experiment were selected three groups of broilers of 100 head each. Chickens of control group was getting basic diet used in the farm, the young birds of I experimental group – addition the basic diet of the feed concentration (Lactobacillus casei, Lactobacillus plantarum, Lactococcus lactis, Bifidobacterium animalis, Propionibacterium freudenreichii) in a dose of 0.5 ml for 1 kg of live weight of chickens; II experimental – the main diet in combination with the probiotic (lactic acid and photosynthetic bacteria, yeasts), which was used by scheme: 1–10 day – in a dose of 0.02 ml in proportion1:100; 11–30 day – 0.05 ml in proportion 1:250; 31–39 day – 0.1 ml in proportion 1:20. The greatest increase the relative gain were observed in broiler chickens the I and II groups: in the age of 21 day the differens was 4.67 and 7.46 % (P < 0.01). The live weight of chickenbroilers at the age of 38 days in the I group receiving feed concentration was higher by 5.4 % compared with the control group, while the probiotic (II group) possible to obtain the live weight to 108.9 g, more than the control group analogs. It has been set that the probiotics increase the relative gain and live weight of chicken-broilers. Probiotics had noticeable positive impact on growth rate of chicken-broilers.
