1. Normally, rabbits enter sexual maturity when they are 3 months old. However, the sexual maturity of rabbits is not only related to the age of rabbits, but also related to the variety, size and feeding mode of rabbits, which generally has a great influence on the weight of rabbits. Generally speaking, sexual maturity of white rabbits may be earlier, and most of them enter sexual maturity at the age of 3 months; Most medium-sized rabbits enter sexual maturity at 4~6 months old; The sexual maturity of big rabbits will be later, and they will enter sexual maturity from 5 to 7 months old. In addition, the estrus time of male rabbits is earlier than that of female rabbits.
2. Male rabbits can estrus all year round, and most denominators are induced to estrus, that is, female rabbits are induced to estrus by stimuli, such as the urine smell of estrus male rabbits. February to April and September to 165438+ 10 are the most vigorous and frequent periods of estrus in rabbits. The estrus of rabbits generally lasts about 1~2 weeks. Some rabbits may be in estrus for a month, and some rabbits will be in estrus for longer. The estrus of rabbits can be divided into prophase, metaphase and anaphase.
Second, the performance of estrus in rabbits
When male rabbits are in estrus, their territorial consciousness and aggressive consciousness are enhanced, and their appetite is decreased. The most typical performance is the behavior of peeing and stamping his hind feet. In estrus, the male rabbit likes to "crawl over" and bite the cage desperately at night.
Same-sex rabbits are prone to fight at the same time in estrus, while opposite-sex rabbits will frequently chase and climb. The urine of rabbits in estrus will become heavier.
When the female rabbit is in estrus, she likes to eat bowls or other items with her chin, and has behaviors such as sniffing and digging. The color of vulva of estrus female rabbits changed from pink in the early estrus to dark red in the late estrus, and the vulva was swollen.
The above is the introduction of Dr. Paw Paw to the estrus time and estrus symptoms of rabbits. I hope the above introduction can deepen the pet owner's understanding of the physiological phenomenon of rabbit estrus!
