Abstract: For the present study, the growth and survival of 30 juvenile axolotls of the
Ambystoma mexicanum species fed with a probiotic were evaluated. At the beginning of the investigation, the specimens had an average size and weight of 4 ± 0.5 (cm) and 2 ± 0.3 (g) respectively. Throughout the study the organisms were kept in six aquariums with 40 L of fresh water, at a temperature of 15 ± 1 °C, with a natural photoperiod and with 5 axolotls each. The axolotls were fed for 24 weeks with the
Tubifex tubifex slimeworm inoculated with 1 X 107 CFU/g with the probiotic PROBION-Forte© (
Bacillus subtilis, Bacillus coagulans and
Clostridium butyricum). To verify the effect of the probiotic on the organisms, survival, growth (height and weight) as well as their degree of well-being were determined. The results reveal that the specimens fed the enriched diet present a survival of 100% compared to those fed the unenriched diet was 75%. On the other hand, the growth showed significant differences between the two treatments (
p<0.006) since the height at the end of the experiment was 18.4 and 11 (cm) with and without the incorporation of the probiotic in the food, respectively. In addition to this, the axolotls fed without the probiotic presented a weight of only 32.52 g; while those fed the probiotic was 57.20 g. This knowledge generated is very recent, but it has been observed that incorporating a probiotic in their diet of organisms has beneficial effects, in turn these results are important in Mexico, since it has great ecological, cultural and commercial value for the country specimens and these investigations will allow us to reduce the pressure that this organism has in its natural habitat, giving way to an increase in aquaculture production.
