Uterine infections aff ect almost half of dairy cows in a dairy herd and they are associated with infertility. High incidence of infertility is oft en associated with culling of cows and 15% (i.e., 54, 230 in 2010) of all cows culled in Canada are eliminated for failing to remain pregnancy. Th ere are no treatments or prevention strategies to curb down the occurrence of uterine infections in dairy cows. Currently antibiotics are used to treat the sick cows; however, the high rate of culling indi cates lack of effi ciency. Th e objective of our work was to treat periparturient cows around parturition with a mixture of three lactic acid bacteria, isolated from the vaginal tract of healthy co ws, to lower the incidence of uterine infections. Two experiments w ere conducted. In the fi rst trial 82 pregnant cows, 2 wk before the expected da y of calving, were randomly assigned into treatment (TRT; received 1 mL of probiotic bacteria in reconstituted skim milk at 10 10 to 10 12 cfu/treatment) and control group (CTR; received 1 mL of carrier only; reconstituted skim milk). Intravaginal infusions were performed once during wk -2, -1, +1, +2, +3, and +4 relative to parturition with probiotic bacteria isolated from the vaginal tracts of healthy cows including a mixture of Lactobacillus sakei FUA 3089, Pediococcus acidilactici FUA 3140, and P. acidilactici FUA 3138. In the second trial 150 pregnant cows, 2 wk before parturition, were randomly assigned into three groups: 1) receiving two probiotic treatments once a week during two weeks before calving; 2) receiving three probiotic treatments two 2 wk before parturition and one on the fi rst wk aft er parturition, and 3) control group receiving 2 treatments with reconstituted skim milk before calving and one sham treatment aft er calving. Results from both experiments showed that administra tion of probiotics in the vaginal tract of periparturient dair y cows lowered the incidence of metritis and pyometra, decreased the incidence of vaginal purulent discharges and the number of cows with abnormal cervical size and uterine fl uctuation. Involution rate of the uterus also was expedited. Treatment improved the overall pregnancy rates for the multiparous cows. More research is warranted to understand the mechanism(s) by which probiotics improved the overall health status of the animals.
