L.Sporogenes as a Vertinary probiotic

As a veterinary probiotic

The effects of L. sporogenes* on the growth performance and changes in microbial flora of the feces and intestinal contents of broiler chicks were investigated. It was found that body weight gain of chicks fed L. sporogenes* at the level of 0.04% was significantly higher than that of the control. Feed efficiency was remarkably improved by the addition of L. sporogenes* at the level of 0.04% and Zn-bacitracin at the 0.05% level. The L. sporogenes* fed group showed better feed efficiency. Intestinal pH was reduced and fecal ammonia concentrations were slightly reduced. In feces, L. sporogenes* and lactobacilli counts were increased and staphylococci and coliforms reduced by the addition of L. sporogenes* .

The recommended dosages of probiotic L. sporogenes* are as follows⁶⁸:

Animal species	Recommended dosage
Chicks	1 - 2 million spores (0.07-0.14 mg LactoSpore^®)
Growers	3 - 6 million spores (0.21-0.42 mg LactoSpore^®)
Layers/broilers	6 - 12 million spores (0.42-0.84 mg LactoSpore^®)
Pups	30 - 60 million spores (2.1-4.2 mg LactoSpore^®)
Dogs	100 - 200 million spores (7-14 mg LactoSpore^®)
Sheep, goats, calves	300 - 400 million spores (21-28 mg LactoSpore^®)
Cattle and horses	800-1000 million spores (56-70 mg LactoSpore^®)

* The taxonomical classification was revised in 1939 in the seventh edition of the Bergey’s Manual of Determinative Bacteriology to B. coagulans, although some researchers continued to use the original name.
