The present application relates to a complex
probiotic preparation containing
Lactobacillus acidophilus WP285 and its use in the preparation of a product for inhibiting the formation of bird stone in pets, the strain in the complex
probiotic preparation is composed of
Bacillus coagulans Bacillus coagulans BC66 strain and
Lactobacillus acidophilus
Lactobacillus acidophilus WP285 strain. The present application finds that both BC66 strain and WP285 strain have excellent effect in inhibiting the formation of bird stone in pets, and they can synergistically enhance each other, the complex
probiotic preparation can effectively reduce the pH value of the simulated stone formation environment and inhibit the formation and deposition of bird stone crystals
in vitro; through pet clinical test, it is confirmed that the complex probiotic preparation can effectively and continuously adjust the
urine pH value of susceptible cats to the weak acidic range which is not conducive to the formation of bird stone, and significantly reduces the number of bird stone crystals in
urine.
