ProStor synbiotic efficiency in poultry farming

We studied the efficiency of the ProStor synbiotic for increasing the growth rate and viability of young chickens and enhancing their natural resistance, livability, and productivity during the adult stage. The homogeneity of young chickens that were reared to replace the adult ones and received the synbiotic with fodder (0.5 kg per 1 t of fodder) during 140 days of rearing was 90.3%, thereby exceeding the value of the same parameter in the control group by 3.2%. The livability of young chickens during the rearing period was 2.67% higher in the experimental group than in the control group, which caused a reduction in the fodder costs and an increase in the yield of young chickens by the time of transfer to adult livestock at the age of 20 weeks. The administration of the ProStor synbiotic in the same concentration to broiler parent stocks with 10-day courses in different biological cycles of egg laying increased the egg production per laying hen by 5.3%, hatching egg yield by 3.6%, and hatched chick yield by 2.1% in the experimental group compared with the control group. Based on the results of the study, it was concluded that the ProStor synbiotic can serve as an adequate replacement for in-feed antibiotics in poultry diets.
