Abstract
This study examined the topical use of locally isolated probiotic bacteria using direct injections and with vaginal sponges in order to compare their effects with a commercial probiotic on enhancing the reproductive efficiency of ewes. Twenty Awassi ewes aged 2.5 - 4 years with an average weight of 47 ± 1.62 kg were used. All the ewes underwent estrus synchronization using vaginal sponges, and were randomly divided into four groups, each with five replicates. The first was the control group, the second (T1) had the vagina directly injected with locally isolated Enterococcus faecium before sponge insertion, the third (T2) had the same bacteria injected with the vaginal sponges, and the fourth (T3) had the commercial probiotic injected with the vaginal sponges. The results showed a significant decrease in estrogen levels in all probiotic treatments compared to the control group, while progesterone levels were not affected by the topical probiotic use in the vagina. There was also a significant reduction in total aerobic bacterial count when the vagina was directly injected with locally isolated bacteria on the 7th and 14th days after sponge insertion. Additionally, injecting locally isolated bacteria with vaginal sponges improved the physical appearance of the vaginal sponges after removal, as well as the reproductive efficiency parameters, which were highest in the group treated with locally isolated bacteria injected with vaginal sponges. It can be concluded that injecting locally isolated lactic acid bacteria into the vaginas of ewes, either directly or with vaginal sponges, reduces the adverse effects associated with sponge insertion, which typically causes heavy mucous secretions after removal, and thus can improve the reproductive efficiency parameters in ewes
