Freemartinism This is one of the most common reproductive abnormalities, mainly congenital, affecting female cattle. It occurs when both male and female conceptus are present in the same uterus. In cattle there is a tendency for the placenta of twin fetuses to merge, thereby causing the circulatory system of the twins to become interconnected. This often affects the development of the female sex organs of the female twin probably due to the androgens of the male blood circulation. Freemartinism is the most commonly recognized noninflammatory condition resulting in infertility involving the tubular reproductive…

Milk fever (new) I Mshindo Media
Milk fever is a condition of mature dairy cows that occurs a few days before, but mostly immediately after calving. It is common in imported high yielding dairy cows, especially Friesian or Channel Island breeds such as Jersey or Guernsey. Milk fever does not occur in indigenous cows. Milk fever is caused by low calcium levels in the body due to the sudden onset of lactation at calving. The nutritional status of the cow in the dry period is known to influence the risk of the disease. Diets low in dry matter such as lush pastures and diets with high calcium during dry…
Retained Placenta: Signs, Cause, Symptoms& Treatment (new)
After giving birth cows sometimes do not drop the afterbirth (placenta) immediately. This can cause problems as decaying placenta tissue can cause a serious bacterial infection of the cow and if untreated the cow can even die.

Birth and Reproduction complications (new) I Mshindo Media
Introduction There are various diseases and abnormalities that affect the reproductive system of domestic animals.
