Preparation and Utilization of the Fluid Synthetic Probiotics Changtaisu for Livestock and Poultry

Objective] The research aimed to study the preparation and utilization of the fluid synthetic proviotics Changtaisu for livestock and poultry.Method] Mixed and synchronous fermentation was used to do the test.Result] The results showed that the tactic acid content of the fluid synthetic probiotics liouid was 2.1 mg/ml,the prolease activity was 565 IU/ml,the diastasum activity was 673 IU/ml and the total live probiotics was more than 1.22×109/ml.Its effective time was 12 months.The results of animal feeding experiment showed that the weight of pigs and chickens increased by 6.1% and 5.5% respectively when the basal diet supplemented by Changtaisu at 2% was used to feed them.The results of veterinary clinic experiment indicated that the effective rate of Changtaisu curing white scour of piglets and pullorum disease was diseased 96.6% and 94.5% respectively.Conclusion] The technique indications of Changtaisu comply with the industry standard.It is very effective in gaining weight,controlling diarrhea and decreasing odor.
