INFLUENCE OF PROBIOTIC PREPARATION YEASTURE-W ON THE PRODUCTIVITY AND MEAT QUALITY OF BROILER CHICKENS**

Abstract

**Original scientific paper Abstract: Probiotics are widely accepted as an alternative to in-feed antibiotics in poultry production. The objective of investigation was to research the effect of probiotic preparation YEASTURE-W for growth performance, meat and carcass quality of broiler chicks. The experiment was performed with 120 Hybro–PN broiler chickens 1−56-day-old, divided into 2 groups of 60 birds each. The both groups were fed crumbled feed mixtures ad libitum. The feed mixture of the experimental group was supplemented with probiotic preparation YEASTURE-W (2 kg/t feed). The birds were maintained on deep litter and watered from stationary watering containers. The results of experiments indicated, that probiotic preparation YEASTURE-W during all experiment period increased the weight of broiler chickens by 10 % (P<0.001) and decreased feed conversion ratio by 9% (P<0.005) comparing with control group. A probiotic showed a tendency to improve the carcass yield and improve the yield of edible parts of broiler chickens. The culinary and chemical properties of poultry became better
