In the family life of rabbits, too, there are problems.
They can mate, but not become pregnant, and sometimes do not want to have offspring at all.
Let's see for what reasons this can happen and how to solve this problem.
How many days will the rabbit give birth?
Pregnancy of the rabbit comes after successful mating and lasts on average from 28 to 30 days. 
Why rabbit is not pregnant
In general, bunnies do not become pregnant or do not want to mate due to their owners' lack of knowledge of the basics of rabbit breeding. Also, the causes may be various pathologies of internal organs or temporary disease states.
The most common causes of this phenomenon are:
- closely related mating;
- old age;
- unhealthy diet;
- weather;
- decrease in sexual hunting;
- moult;
- over exploitation;
- character;
- nymphomania;
- anaprodisia;
- fremartinism.
Important! Keep track of the constant availability of clean drinking water during the last periods of pregnancy of the rabbit. If there is no water during childbirth, the dehydrated and helpless animal can eat its offspring, and the owner will not even know what the birth was.
Closely related mating
When mating of close relatives occurs in the rabbit family, the herd degenerates, the offspring is born weak and small. Moreover, offspring from closely related mating is often born barren - incapable of conception. 
It is because of this that it is necessary to strictly restrict interfamily relations and record the data on joints in a special journal, where to note information about parents.
Old age
A middle-aged age is one of the most common reasons for the lack of offspring in animals. The age limit available for the birth of offspring is 4-5 years old. After this age, the so-called menopause begins in rabbits.
The solution to the problem is a constant record of the age of the animals that are used for breeding and constantly changing them.
Important! In the diet of rabbits there should be enough plant proteins so that they do not give up offspring and do not eat it.
Malnutrition
A dangerous factor for the lack of habits in rabbits are insufficiency and redundancy in feeding. Lack of vitamins and beneficial trace elements can lead to hormonal deficiency. In rabbits under such conditions, there is no desire to mate, and in males spermatozoa lose activity.
Overfeeding is also bad for the fertile functions of animals. The body accumulates a large amount of fat, which reduces the sexual activity of rabbits, the ability to conceive. Excess weight affects embryo mortality, the occurrence of low-birth pregnancies, and reduced quality of breast milk. 
In order to increase the weight of an animal with underfeeding, you need to add bread, corn, potatoes to the diet and reduce the amount of rough and juicy food. Moldy grains are harmful to animals. This can cause poisoning and disrupt the hormonal systems.
Because of weather
Equally bad for the sexual activity of rabbits is affected by both excessively hot and frosty weather. Also rabbit reluctant to breed with a short duration of daylight. Favorable conditions for active mating of these animals are light day at least 10 hours and the air temperature is not higher than + 25 ° C.
Did you know? Rabbits are mistakenly referred to as rodents, when in fact they are lagomorphs.
Reduced sex hunting
The period of decline of sexual hunting is in July and August. Thus, rabbits regulate their sexual activity so as not to bear and not raise their offspring in the fall. It is in autumn that rabbits are preparing for winter, accumulating fat.
Therefore, pregnancy during this period is not the best idea for them. Helping rabbits and solving a problem in this situation is not worth it. The most reasonable action is to provide a full and vitamin-rich diet, so that animals calmly prepare for winter. 
Moult
The fact is that during the molting decreases the hormones of animals. At this moment, the animal feels the weakest and most defenseless, and therefore it restricts reproduction, not allowing the males to approach it.
Find out also what to do if the rabbit's eyes fester, why the rabbits have blood, how to protect the rabbit from mosquitoes, why the rabbits don't mate, why the rabbits die, what to do if the rabbit nibbles the cage.
Overuse
The rabbits have such physiological features that they can become pregnant again immediately after birth. With this approach, the rabbit at the same time feeds her offspring and wears the following. This feature is often used by breeders, pairing rabbits for 1-3 days after hatching.
Such over-exploitation leads to the fact that the bunny is aging earlier, earlier she refuses to cover. Two years later, they are rather exhausted, they eat offspring, they do not feed enough offspring and care for them. In over-exploited rabbits, frequent miscarriages, rabbits are born with vices.
Important! Limit the amount of feed used, containing phytohormones: clover, horse sorrel, alfalfa, peas, cabbage, corn leaves and beet tops.
To avoid such phenomena, mating is desirable to carry out no earlier than 30 days after birth. The offspring are weaned from the mother for a month and a half. Thus, the rabbit for about 2 years will be able to produce high-quality and healthy offspring. 
Character
Due to the nature of the mature rabbit, she can refuse mating with inexperienced males. This is explained by the fact that the sweat glands in young males emit a specific odor, unpleasant for an adult female. This problem can be solved by fixing the female for the first few times during the landing. Then they get used to each other.
Nymphomania
Sometimes hormonal pathologies in females lead to the rejection of mating. Most often this is due to nymphomania - a state of increased sexual excitability.
Did you know? Nymphomania in rabbits is often called uterine rabies.
With such a violation, mucus is constantly emitted from the vulva, the rabbit is over-excited, but does not allow itself to be covered and can injure a person when trying to fix it for mating. This disease is treated with sex hormones. The causes of its occurrence are associated with malnutrition, diseases of the genital organs and adrenal glands.
Anaprodisia
Anaphodisia is another hormone pathology in rabbits, when sexual cycles are disrupted, estrus is weakened or completely stops. The appearance of pathology is associated with poor conditions, unbalanced nutrition, insufficient lighting, gynecological diseases, and sudden temperature fluctuations. 
Anaprodisia is indicated by the absence of hunting for 3-4 months.
The first aid in this disease is to add vitamin feed to the diet. If it does not help, then the animal is subject to rejection. Decorative rabbits undergo hormonal treatment and receive vitamins and minerals courses.
Important! If the sex hunt does not show up to 4-8 months, you need to contact your veterinarian for help.
Freemartinism
Freemartinism refers to anatomical or physiological abnormalities in the structure of the genital organs of animals. Such pathologies are not treated, the ability to reproduce offspring is absent.
Rabbit made a nest and does not give birth
In rabbits, as in other animal species, the phenomenon of false pregnancy often occurs. It occurs if, during mating, there is no fusion of sperm with ova.
Although there was no conception, the rabbit begins to behave like a pregnant woman - makes a nest for offspring, eats more, plucks down the fluff on her breast, her mammary glands increase and milk arrives to them. 
By the 15th-20th day of an imaginary pregnancy, its symptoms dramatically disappear on their own. Sometimes in this case, the help of a veterinarian is required, which introduces special hormones to the animal.
Can a rabbit give birth later?
In some cases, the gestation period may increase up to 36 days. If after this period the rabbit does not give birth, then she has serious pathologies and she urgently needs help.
Rabbits need constant care and care, and for them to give healthy offspring in a timely manner, their physiological and psychological characteristics must be taken into account. Keeping animals in proper conditions and attentive attitude towards them guarantees success in their rearing.
