Reasons for Rabbits' Difficulty in Conceiving: A Compre

Reasons for the Difficulty in Rabbit Pregnancy

1. Body Condition Factors: A lack of exercise combined with excessive consumption of highprotein, highfat, and highcarbohydrate feed can lead to obesity in female rabbits. Over time, this obesity can cause fat deposits in the ovaries and lead to the degeneration of the ovarian follicle epithelium, resulting in anestrus or difficulty in conception. Poor management of the rabbits, or infections with parasites, can also lead to overeating without gaining weight, disrupting the body's metabolism and altering the reproductive system, thus causing infertility.

2. Nutritional Deficiencies in Feed: Reproduction in animals requires adequate nutrition. A deficiency in certain nutrients in the female rabbit's body can lead to nutritional infertility. For example, a lack of vitamins such as Vitamin A or Vitamin B can result in infertility. The reasons for these deficiencies causing infertility have been previously analyzed by Oxygen Pet Doctor, and will not be elaborated on here. In summary, nutritional deficiencies are a significant factor contributing to infertility in female rabbits.

3. Environmental Factors:

(1) Light Conditions: The sexual activity of rabbits is closely related to light exposure. Insufficient light or a lack of light can greatly affect the reproduction of female rabbits. Breeding rabbits typically require 14 to 16 hours of light daily, and both excessive and insufficient light can impact the activity of the ovaries.

(2) Climate Conditions: Weather conditions such as rain and snow can cause female rabbits in estrus to stop cycling temporarily. The ideal environmental temperature for breeding rabbits is between 15 to 25°C. Generally, in winter, female rabbits can only cycle normally when the temperature is above 5°C.

4. Reproductive System Diseases: Diseases that affect the female rabbit's reproductive system, such as hypofunction or dysfunction of the pituitary gland, can lead to congenital malformations of the reproductive organs, such as vaginal closure, incomplete uterine development, incomplete cervical and ovarian function, etc. Inflammation of the reproductive system, such as ovarian inflammation and endometritis, can also cause anestrus and low fertility rates.

5. Poor Quality of Male Rabbits: Malformed testicles in male rabbits, such as slow sperm production, malformed sperm, and low sperm count, can lead to difficulties in mating and infertility. High temperatures in summer can cause the testicles to sag, and injuries or infections can occur if they are accidentally stepped on. In winter, cold temperatures can cause frostbite to the testicles, reducing the quality of the semen and leading to infertility despite successful mating.

Oxygen Pet Doctor's Summary: There are many reasons for the difficulty in rabbit pregnancy. In addition to the aforementioned reasons, factors such as molting during autumn and the age of the female rabbit can also reduce the estrus and fertility rates. Therefore, it is essential for owners to identify the specific causes of infertility in female rabbits to better address the issue.
