The microbiota of cervical mucus besides conception rate were studied following intrauterine administration of Oyster glycogen @ 500 µg in 500 ml PBS to repeat breeder cross bred cow suffered with endometritis of mild (Group I) and severe grades (Group II). Each group included 10 ailing cows while 6 repeat breeders with mild to severe grade endometritis constituted Group III to serve as control and received only PBS. The pre-treatment bacterial load (5.31±0.22 and 5. 73±0.18 x 108 cfu/ml) was higher significantly (P<0.05) in Group I and II which diminished to 0.89±0.11 and 0.97±0.07 x 108 cfu/ml at post-treatment oestrus in both groups, respectively; whereas such a decline was absent in control group. The E. coli, Proteus, Streptococci and mixed isolates were identified in all three groups but the pre-treatment spectra of their prevalence varied with an abundance of E. coli, 40 and 30 %, followed by mixed isolates, 30 and 40%, in Group I and II, respectively which in conjuction with other isolates decreased to yield no bacterial growth in 70 and 60 percent sample at post-treatment oestrus in these two groups. Higher overall conception rate (7/10, 70%) with an optimum percentage (40%) to the first service was resulted in Group I than slightly lower percentage in Group II (6/10, 60%) than its absolute failure in control group. It is concluded that Oyster glycogen@500 µg, intra-uterine, effectively cured the endometritis of mild and severe grades in repeat breeders and also improved the conception with slightly higher rate from first service in group of mild endometritis.
