Causes of Rabbit Abortion: Understanding and Prevention

Part 1: Causes of Fetal Death and Abortion in Pregnant Rabbits

1. Nutritional Causes of Fetal Death and Abortion

(1) A diet consisting of a single type of feed and improper dietary balance is often the culprit behind nutritional fetal death and abortion in pregnant rabbits. An imbalanced diet can lead to malnutrition, which is a significant risk factor. Specifically, if the rabbit feed lacks adequate protein, the fundamental building blocks for fetal development are insufficient, potentially causing developmental stuntedness or even termination, leading to fetal death or abortion.

(2) A deficiency in vitamins and minerals can weaken a pregnant rabbit's ability to adapt to its environment and resist diseases, which can ultimately result in fetal death or abortion.

(3) A lack of Vitamin A can disrupt the promotion of epithelial tissue function, often leading to keratinization and desquamation of the uterine mucosa and chorion cells in rabbits. This can result in a lack of adhesion in the placenta, causing placental detachment or fetal death. Additionally, a deficiency in Vitamin E during the later stages of pregnancy can easily lead to premature birth.

(4) A deficiency in minerals like calcium and phosphorus, or trace elements such as selenium and zinc, can cause inadequate nutritional supply to the fetus, potentially leading to developmental interruption or deformities, and ultimately resulting in fetal death or abortion.

2. Toxic Causes of Fetal Death and Abortion

Pregnant rabbits consuming moldy, rotten, or spoiled feed can easily suffer from fetal death and abortion. Moreover, high acidity in rabbit feed or contamination by pesticides can also lead to poisoning in pregnant rabbits, causing digestive system disorders and prompting fetal death or abortion.

3. Mechanical Causes of Fetal Death and Abortion

Various mechanical factors can lead to abortion, such as excessive exercise, improper handling, or rough handling of the fetus. Additionally, pregnant rabbits that are frightened can easily experience fetal death.

4. Disease Causes of Fetal Death and Abortion

Various diseases, including epidemic enteritis, high fever, underdeveloped reproductive organs, and various parasitic diseases, can cause abortion in pregnant rabbits. Furthermore, administering excessive medication to pregnant rabbits during pregnancy can also lead to abortion. Additionally, viruses are an oftenoverlooked factor contributing to fetal death or abortion in pregnant rabbits.
