Nutritional factors
Excessive obesity during labor leads to weakness in the contraction of the uterine muscles, delayed expulsion of the fetus, and descent of the placenta as a result of early muscle strain during the birth process itself.
Calcium deficiency in the blood leads to weak uterine muscle contraction, which leads to difficult labor and delayed placenta descent
Selenium has an effective role in increasing the rate of uterine resistance to infection, a role that complements the presence of
Vitamin E, which has been proven that the deficiency of this vitamin in the prenatal period leads to a high percentage of placental retention and uterine infections.
environmental factors
We all know that the animal gives birth in an environment that is full of infection, and the source of this infection may be from the floor on which the animal sleeps, where the cervix is open and the uterus is in a state of contraction and relaxation, which may lead to the entry of bacteria, viruses, fungi, and soil into the uterus, hence the importance of the cleanliness of the place of birth.
intervention during childbirth
Early or wrong intervention during childbirth and the resulting contamination during this process is a major cause of placenta retention and uterine infections.
Vaccination of cows is not common
Scientific studies have shown that 5-20% of cows are vaccinated, and it is not common, and these cows often have a corpus luteum that secretes the progesterone hormone, which leads to a decrease in the number of white blood cells coming from the uterus, which leads to weak immunity, as well as entering the vaccination catheter leads to some wounds In the reproductive system, which leads to a cycle of bacterial invasion, which results in the occurrence of uterine infections
