Female rabbit infertility hinders the cause of raising rabbits how to treat female rabbit infertility symptomatic

The problem of female rabbit infertility has always been an important problem affecting the development of rabbit industry. According to the clinical practice and social investigation of rabbit breeders in recent years, the causes and prevention countermeasures of female rabbit infertility were summarized.

Female rabbit

First, the causes of infertility in female rabbits:

1. Nutritional infertility: lack of various nutrients, especially protein and sugar, lead to malnutrition, hinder energy and metabolism, and functional and other changes in the reproductive system lead to infertility.

2. Vitamin A deficiency: vitamin A deficiency affects protein synthesis, hinders mineral and other metabolic processes, stagnates growth and development, endocrine glands atrophy, hormone secretion deficiency, uterine mucosal epithelial degeneration, follicular atresia or the formation of cysts, so that the female rabbit can not estrus and ovulation.

3. Lack of vitamin B1: when lack of vitamin B1, uterine contraction can be weakened, oocyte production and ovulation are destroyed, and long-term non-estrus results in infertility.

4. Vitamin E deficiency: when vitamin E deficiency, it can cause pregnancy interruption, stillbirth, weak fetus or recessive abortion (embryo disappearance). Long-term deficiency will cause degeneration of ovary and uterine mucosa of female rabbits, resulting in permanent infertility.

5. Lack of minerals such as calcium and phosphorus: deficiency of minerals such as calcium and phosphorus can cause dysfunction of various organs, among which reproductive dysfunction appears earlier. Therefore, calcium and phosphorus are indispensable nutrients to ensure the health, growth and reproduction of female rabbits.

6. Overweight causes infertility: long-term overfeeding of protein, fat and carbohydrate feed reduces the amount of exercise. After overfeeding, the ovary fat deposits and follicular epithelial degeneration leads to infertility.

7, reproductive organ diseases: vaginal atresia, uterine hypoplasia, lack of uterine horn, cervix, such as ovarian insufficiency, ovulitis, salpingitis, endometritis, uterine pus, vaginitis and so on.

8. The causes of male rabbits: testicular dysplasia, slow spermatogenesis, abnormal sperm, decreased sperm volume and semen volume, poor sperm motility, lack of libido, difficult mating and so on will lead to female rabbit infertility.

2. Prevention and treatment of infertility in female rabbits:

1. Vitamin A deficiency prevention and treatment: vitamin A mainly exists in animal liver. Carotene in plants can be converted into vitamin An in animals, supplying more grass and high-quality hay, carrots, pumpkins, etc., and fed with vitamin A treatment, such as concentrated cod liver oil or vitamin A preparation, the capsule contains 25000 IU, commonly used 1 tablet per piece? Once.

2. Vitamin E deficiency prevention and treatment: generally, vitamin E is 0.32 ~ 1.4 mg per kilogram of body weight per day, and female rabbits can add 16.7 mg of vitamin E per kg of feed; add some vegetable oil, such as soybean oil and peanut oil, to supplement vitamin E; hypodermic or intramuscular injection of vitamin E 20 ~ 30 mg. While using vitamin E, it is best to use 0.2 mg of sodium selenite per kilogram of body weight.

3. Treatment of deficiency of vitamin B1: deficiency of vitamin B1 is caused by lack of thiamine in tissue. Thiamine is high in rice bran, fresh vegetables, wheat bran, legumes and yeast. Therefore, it should be matched properly in the feed. The patients were treated with 2 tablets of thiamine orally. The injection was injected intramuscularly with 2 ml / day. Riboflavin tablets, 2 tablets each time, twice a day.

4. Treatment of endometritis: intramuscular injection of diethylstilbestrol 0.5 mg, or posterior pituitary hormone 5 mg, and rinse saline once a day, 2 times a day.

5. Prevention and treatment of uterine empyema: in order to expel uterine empyema, 0.2-0.5 mg diethylstilbestrol was injected first, and then 2~3IU posterior pituitary hormone was injected 3-5 days later, antibiotics were injected and appropriate drainage was carried out at the same time.

6. Treatment of vaginitis: rinse vagina and discharge vaginal exudate as soon as possible, rinse with normal saline, 0.1% potassium permanganate and 0.02% furacilin solution; apply ointment, after washing, apply iodine glycerin, sulfonamide ointment and penicillin ointment on vaginal mucosa.

7. Keep the proper fatness of empty pregnant female rabbits: empty pregnant female rabbits should keep 7-8% fat, too fat and too thin will affect estrus and mating. Female rabbits without sunlight for a long time should be transferred to cages with sufficient light to promote metabolism. Male rabbits and artificial estrus methods can be used for female rabbits with long-term non-estrus.
