What causes infertility in female rabbits
Whether they are pet rabbits or meat rabbits, rabbits have a certain market demand in China, and there is now a relatively large breeding area in China. The most important thing in rabbit farming is to do a good job in keeping breeding stock, so the raising of female rabbits is crucial. However, many breeders often find that female rabbits are infertile during the breeding process. So what causes infertility in female rabbits? Let's take a look together below!
1. Improper feeding
Improper management is the main factor causing infertility in female rabbits. When feeding, attention must be paid to controlling the nutritional ratio in the feed. Prevent breeding rabbits from becoming too fat and overweight, and reasonably formulate feed according to actual conditions, appropriately adjusting the proportion of concentrate. Keep the proportion of crude fiber in the feed at about 16%. Then special attention should be paid to female rabbits after giving birth. Some female rabbits, because of a relatively large number of offspring, face increased nursing pressure. This causes excessive nutrient loss in the female rabbits, and their body condition will also be affected, so we must reasonably increase the feeding amount and nutritional ratio.
2. Lack of technique
When raising rabbits, we must have a good grasp of the estrus time of female rabbits. If the estrus time of female rabbits cannot be determined in time, resulting in improper mating time, it can very easily lead to infertility. After a female rabbit enters estrus, its food intake will decrease significantly, it will be restless, and it will raise its tail from time to time. If there is a male rabbit nearby, it will approach the male rabbit and show mating behavior. We can also observe the vulva of the female rabbit. After estrus, the vulva is moist and swollen. Therefore, we must ensure that we have mature techniques to promptly detect estrus in female rabbits and improve the conception rate.
3. Improper use of drugs
In order to improve the conception rate of female rabbits during the breeding process, many breeders often use various drugs such as estrus-inducing oxytocin to promote estrus in female rabbits. Although reasonable use of this drug can indeed effectively promote estrus in female rabbits, attention must be paid to controlling the dosage. If the dosage is too large or it is used too many times, it will cause reproductive system disorders in female rabbits. Not only will it fail to promote estrus, but it will also cause estrus to be unobvious and irregular. Even if estrus in the female rabbit is detected in time, the follicles will be affected and reduced because of this, thus leading to infertility in the female rabbit.
4. Reproductive tract diseases
The disease resistance of female rabbits is relatively poor. If management is poor, it can very easily cause female rabbits to become ill. Especially when some reproductive tract diseases appear, they will seriously affect the mating work of female rabbits. If the vulva of the female rabbit becomes red, swollen, inflamed, or even ulcerated, it is very likely that it has already contracted a reproductive tract disease. In this situation, the success rate of conception in the female rabbit is very small. So when it is discovered, it is necessary to promptly clean and disinfect with agents such as potassium permanganate, and then use internal sulfadiazine, etc., at least twice a day. Mating work can only be carried out after the inflammation has completely recovered.
The above is a brief introduction to the causes of infertility in female rabbits. Infertility in female rabbits may also be a congenital cause. In this case, diethylstilbestrol and other agents can be used to promote the release of follicle-stimulating hormone. If there is no estrus for a long time and the treatment effect is poor, then they should be culled in time. That is all for today's introduction.
