The experiment was designed according to the one-factor comparative batching method, including: 1 control group (DC) and 1 experimental group (TN). Each group had 1,000 frogs. The experiment was repeated 2 times. The total number of frogs studied was 4,000. The experimental group was fed a complete compound feed supplemented with 0.20% Lacto product, and the control group was fed a complete compound feed without Lacto product added. The results showed that: The addition of Lacto product increased the survival rate of frogs by 2.55%. The weight of frogs in the experimental group (256.85g/frog) was higher than that in the control group (212.35g/frog)
At the same time, the addition of Lacto product had the effect of increasing the efficiency of feed use, the FCR of the experimental group (1.36kg) was lower than that of the control group (1.43kg). Thus, the regular use of probiotics improved the efficiency of livestock production.
