Slow down the breeding and improve the benefit-- the breeding technique of Jiuyi Mountain Rabbit

When you talk about Jiuyi Mountain, you will think of Mao Zedong's well-known poem: Baiyun flies on Jiuyun Mountain, and the Emperor takes advantage of the wind. Spotted bamboo a thousand tears, Hongxia ten thousand hundred heavy clothes. In addition to the famous spotted bamboo, there is another treasure in Jiuyi Mountain. This treasure has a very prominent feature, and it is precisely because of this feature that Ouyang Dingquan's joys and sorrows have been mixed up with it ever since.

Ouyang Dingquan's favorite treasure is the Jiuyi Mountain Rabbit. Compared with other rabbits, this rabbit is petite, has a smaller head and shorter ears, and is only found locally in Jiuyi Mountain, Hunan Province, but not anywhere else.

Because the Jiuyi Mountain Rabbit is very fertile and can sit on the moon every month, the local people have also given it a nickname, Yueyue Rabbit. Generally speaking, rabbits give birth to five or six litters a year, but Jiuyushan rabbits can have one litter every month, and there are twelve nests in a year. According to this rabbit's method, the scale can develop quickly, and Ouyang Dingquan has made a wishful thinking of raising Jiuyushan rabbits.

According to the growing principle that chickens lay eggs and eggs reproduce chickens, Ouyang Dingquan thinks that it will not take long, and this wishful thinking will be really successful. He weaves a dream of getting rich quickly and wants to breed it on a large scale. Ouyang Dingquan dreams that after large-scale breeding, he will let Jiuyushan rabbits live hard. Before long, the whole farm will be full of rabbits. Compared with other kinds of rabbits, the benefit will be many times better.

Ouyang Dingquan thought that as long as he took good care of these babies and let them fall in love and have more children, they could hold the purse and wait for the money to dress. In 2010, he began to breed Jiuyi Mountain Rabbit. In order to raise the rabbit well, he gave everything he had to give, including green feed and nutritious concentrate. And in order to prevent inbreeding and improve the quality of rabbits, he did not adopt the free-range breeding model of farmers, but kept them in cages. As expected, under his meticulous care, the Jiuyi mountain rabbit can really be born, and it is born every month in estrus.

In theory, the idea of making money is reliable, and then it's time to take the purse and wait for the money. But half a year later, not only did he not receive so much money, but he could hardly keep the rabbit! What's going on? He's in big trouble! I had expected to harvest thousands of rabbits in half a year, but I didn't expect that the number of rabbits was enough, but almost half of them were sick rabbits, disabled rabbits who could not walk, or even dead rabbits.

The survival rate of the rabbit is too low. Is there something wrong with the rabbit or is there something wrong with the breeding method? In fact, from the beginning, Ouyang Dingquan raised very carefully for the dream in his heart. The bad situation begins after the female rabbit has been breeding rapidly for a period of time. The mother rabbit is reluctant to breast-feed the rabbit at first, and may even bite the rabbit. This problem can not be delayed, the rabbit can not eat milk, grow well, naturally can not sell a good price. After inspection, Ouyang Dingquan found that the problem was the lack of milk. It takes about 28 days for the rabbit to be weaned. Now it is not time for the mother rabbit to be weaned. The mother rabbit has no milk. The rabbit naturally does not relent, pestering the mother rabbit to drink milk.

Ouyang Dingquan, head of a rabbit farm in Jiuyi Mountain, Hunan Province, said: "if the rabbit still sucks its nipple and makes it hurt, it will bite." There is no milk to eat, we consider to add a little nutrition to it, give it some things to promote milk, such as soybeans, kelp, these things can promote milk, but it still does not, after a few days to observe it is still not, the rabbit has no milk to eat, the adverse consequences soon appeared. Due to insufficient milk and weak physique, the little rabbit began to get a variety of diseases and then died. Even the survival of the rabbit, the growth can not make Ouyang Dingquan satisfied. The most important thing is that rabbits lack nutrition. It was malnourished when it was young. Like a tree or a child, feeling sick. Slowly can not grow up, no matter how long only three jin four jin.

Haste makes waste. Ouyang Dingquan found that his previous wishful thinking was in vain. This month, the rabbit was born, but the milk could not keep up. If the milk was insufficient, the rabbit could not grow up. Naturally, he could not earn money, let alone make money. Ouyang Dingquan's heart was half cold.

Seeing that his money-making plan was going to fall through, Ouyang Dingquan found a man named Li Zhiping in the hope that he could help him solve the problem that the female rabbit had no milk. Unexpectedly, Li Zhiping gave him an unexpected suggestion. This suggestion made Ouyang Dingquan's heart completely fall into the bottom of the valley. Li Zhiping, an agricultural technology extension researcher in Ningyuan County, has studied Jiuyi Mountain Rabbit for many years. He believes that the reason why Ouyang Dingquan's rabbits do not grow well lies in blood matching.

As soon as he heard that there was a problem with blood matching, Ouyang Dingquan's heart thumped, because he knew that the reason why Jiuyushan rabbits could become moon rabbits was that they could be in estrus and mate with each other after giving birth to rabbits. The rabbit's pregnancy cycle is 30 days, and blood matching allows the rabbit to conceive and give birth almost continuously. In local peasant households, fences are generally used for free breeding. Female rabbits who have just given birth to rabbits do not affect estrus, and they can also talk about a free love with male rabbits for blood matching. Not only will farmers not interfere, on the contrary, they think that this will bring good benefits. Although Ouyang Dingquan's farm has carried out separate cage breeding in order to avoid inbreeding, it still follows the traditional practice of blood mating in order to have more children and raise quickly. Now, experts propose to ban blood matching, which means that the moon rabbit will not be born every month, which makes Ouyang Dingquan very unhappy.

In the view of experts, due to the limited scale of local farmers, most of the rabbits bred are sold early, so the adverse consequences of blood matching are not obvious. While Ouyang Dingquan wants to breed commercial rabbits on a large scale, the problem caused by blood matching is very prominent. The reason why the female rabbit does not have enough milk lies in the matching of blood. After the female rabbit is pregnant, the progesterone in the body will lead to a decrease in breast milk. Especially in the late stage of pregnancy, the fetus in the belly grows fast, while the rabbit outside the belly wants milk to drink. The female rabbit drags two and cannot take care of both inside and outside, so the quality of the rabbit will naturally be affected.

Li Zhiping said: "after blood matching, the survival rate of rabbits is much lower, especially when it is close to weaning, it is easy to be insufficient, and there may be diseases of the rabbit's gastrointestinal tract. After weaning, the rabbits are kept for two or three months. At this time, the mortality rate is a little higher, frequent breeding is adopted, and the mortality rate is about 40%."

In order to solve the problem of high mortality of rabbits, Li Zhiping went on to put forward a proposal that Ouyang Dingquan could not accept. Li Zhiping recalled: "the advice I gave them at that time was to slow down the birth rate of rabbits and to ensure the quality of rabbits. The original breeding rate of female rabbits was 10 and 11 births a year, but now it has been changed to 6 to 7 births."

Obviously, the suggestion of slowing down the birth rate and letting the Moon Rabbit give birth slowly is completely opposite to Ouyang's idea of making money. Originally, rabbits can give birth to 10-11 litters a year, but they are only allowed to have 6-11 litters. If the number of rabbits is reduced and the scale cannot be expanded, how can they make money?. Ouyang Dingquan feels that the experts have negated all his previous ideas. In this way, can the rabbit be kept? And the expert unexpectedly assured him that allowing the moon rabbit to give birth slowly will not only not affect the efficiency, but also increase by 20% to 30% compared with the original.

Ouyang Dingquan, head of a rabbit farm in Jiuyi Mountain, Hunan Province, explained: "there is no change in the total number of births. The total number of births and the total number of births of a female rabbit are actually the same, but the survival rate of young rabbits is higher, the growth rate of meat rabbits is also higher, and the feed reward is also higher." After listening to the expert's explanation, combined with the situation of his own farm, Ouyang Dingquan also felt that there was some truth, but he was also skeptical. As a doctor, he decided to take out a small number of rabbits to do an experiment to see if the quantity can be reduced and whether the benefit can be found in terms of quality. According to experts, it is important to change the breeding time if rabbits are to be born more slowly.

Li Zhiping said: "the estrus cycle of Jiuyi Mountain Rabbit is short and lasts for a long time. The general estrous cycle is 8-10 days, and the estrous duration is 2-3 days. The estrous cycle of Jiuyi Mountain Rabbit is 2-3 days shorter than that of other rabbit breeds. The duration of estrus is 1 day longer than other rabbit breeds."

The duration of estrus is long and the interval is short, which indicates that the suitable breeding time for Jiuyi mountain rabbit is more abundant. Experts also gave clear guidance on the timing of mating. Li Zhiping said, "when do we usually approach weaning or after weaning for female rabbits who are weaned? Generally speaking, if we are weaned for 28 days, we will have to rebreed after 21 days, a week in advance of weaning. "

After the adjustment, the female rabbit and the male rabbit can not date casually, which ensures that the born rabbit has enough milk to eat. In addition to the time limit, experts also put forward strict requirements for the size of female rabbits suitable for pregnancy. Li Zhiping explained: "to judge whether this rabbit can be bred or not, it mainly depends on its physical condition. The female rabbit's physical condition is more fleshy on the back, feeling fleshy, but not too fat." There is fat, a little body fat, we are talking about 80% body fat bar, the weight should reach 2.6 kilograms. "

When it comes to mating time, if the female rabbit does not meet this hard target, she cannot date the male rabbit, and the purpose of doing this is for the sake of the next generation. Li Zhiping said: "80% body fat can ensure that female rabbits have a higher conception rate and higher litter number. Too fat and too thin will lead to a decrease in litter number, and 80% body fat will breed rabbits in the best condition." After such an adjustment by experts, the growth of rabbits in Ouyang Dingquan's farm has greatly improved. The survival rate of rabbits has increased. Ouyang Dingquan found that after the physique of female rabbits was restored, the number of babies per litter also increased.

Ouyang Dingquan, head of a rabbit farm in Jiuyi Mountain, Hunan Province, said: "in the past, according to the number of cubs she gave birth to, it could reach about 60, but the actual survival rate was about 40, so it was reduced by 1/3. Now, after the implementation of family planning, basically one litter for one and a half to two months, but now the average number of cubs can reach 9, 6954, an increase of about 10. And this has to go out of the hurdle faster. "

As soon as the accounts are settled, Ouyang Dingquan is convinced to the experts. So in the early summer of the following year, he relieved to cancel the blood match in the whole audience and let the moon rabbit live slowly. But then, there was an unexpected phenomenon of Ouyang Dingquan. The Moon Rabbit, which slowed down the birth rate, unexpectedly began to slack off. The female rabbit did not come into estrus and lay in the cage all day.

The keeper put the female rabbit in the cage of the male rabbit, hoping that the male rabbit could relieve the stuffy urge of the female rabbit. Unexpectedly, the female rabbit not only did not make out with the male rabbit, but also did not let the male rabbit get close, and even got into a fight. Some female rabbits cannot conceive a child even if they reluctantly enter the bridal chamber with the male rabbit. Why did the moon rabbit with super reproductive ability suddenly get infertility? After observation, the keeper found that the changes of the rabbits were related to the weather.

When the weather is hot, if it is generally hot to about 30 ℃, the rabbit will lie there and will not move. If the weather is generally more than 20 degrees, you will usually drink two buckets of water, and if the weather is hot, you will need at least four buckets of water. Jiuyi Mountain Rabbit is afraid of heat, which is not outstanding when raising in farm households. Why is it that when it comes to intensive farming, it is afraid of heat?

It turned out that Ouyang Dingquan's farm in order to save space, rabbits live in three-story buildings, can not be close to the ground, the density is also high, the air is naturally not as cool as farmers. When the temperature is high, the rabbits are so hot that they don't want to fall in love. Li Zhiping explained: "it is a common phenomenon that high temperature causes a decrease in libido in Jiuyi mountain rabbits. when the temperature exceeds 33 ℃, the male rabbit cannot produce sperm with normal motility, which is dead sperm, and the female rabbit also feels difficulty breathing."

In order to let the rabbit be in the mood to fall in love, the farm made a transformation to the enclosure. First of all, heat insulation is added to the roof, curtains that can rise and fall automatically are installed on both sides, thatch is covered on the roof, and a roof fountain is installed at the same time. When the weather is hot, when the fountain is opened, the rabbit is like living in a water curtain cave, which is naturally cool.

After the temperature was controlled, the rabbits began to fall in love and have children again. The fast pace of each month's life has been changed into a slow pace of giving birth to two nests at most in three months, and the comprehensive breeding benefit of the month rabbit has been increased by more than 30%.
