EMBRYONIC MORTALITY AND UTERINE INFECTION IN THE PIG [PDF]
Reproduction, 1974 Summary. Thirty-nine gilts were slaughtered 9 and 13 days post coitum (p.c.) to determine if the period of elongation and first attachment of the blastocyst to the uterus was critical in embryonic survival. The bacterial flora of the uteri of thirty-eight pigs were cultured to determine the relationship between bacterial infection and
