Their successful birth proves that somatic cloned sheep and embryonic cloned sheep have the same reproductive function as ordinary sheep, which is the first case in the world.
Yesterday at noon, at the China Clone Animal Base in Yangling, Yang Yang, the world's first batch of somatic clones, finally gave birth to twins-Huanhuan and Phoebe. Their father is the "handsome boy" of the first batch of Angolan goats cloned from embryos in the world. Their successful birth proves that somatic cloned sheep and embryonic cloned sheep have the same reproductive function as ordinary sheep. This is the first case in the world.
Yesterday morning, "Yang Yang" showed obvious signs of labor. At 6 o'clock, all the other sheep were still sleeping, only he walked uneasily around the sheepfold, chirping from time to time. After a while, the breeder put "Yang Yang" on the grass outside the circle as usual, but it obviously had a poor appetite. After only a few bites, it slowly strolled back into the circle and rubbed its head and neck on the wall. The staff told the reporter: "There is a play!"
Disinfectants, instruments, oxygen bags and veterinarians are all in place. The staff also specially cut two big red carpets to make cloth for Yang Yang, and at the same time drove Yang Yang to the most secluded circle, laying soft dry straw on the corner. Professor Hua, director of China Animal Cloning Base, checked the situation again and again. At 9: 49, when the reporter asked again, Professor Wang spit out four words: "Enemy at the Gates."
In order to ensure the quiet production of Yang Yang, at 9: 56, except for a few staff members, no one is allowed to go near the sheepfold; 10 and 13, the gate of the base was closed and the atmosphere was particularly tense. The breeder never leaves the circle of "Yang Yang".
In the early morning 1 1, the uterine suppository of "Yang Yang" flowed out of the vagina; 1 1: 34, "Yang Yang" fell to the ground with his front legs struggling and his ass struggling, looking very painful; At 1 1: 36, the breeder handed Yang Yang a handful of grass, which Yang Yang could still eat. 1 1: 49, "Yang Yang" lying in the corner began to moan; 1 1: 52, the groan was long and harsh, and Professor Wang urgently commanded the staff to bring instruments and a basin of disinfectant; 1 1: 54, "Yang Yang" was carried on the red carpet, and the lamb's right front leg was exposed, giving a cry of pain. 1 1: 55, the little head of the lamb also appeared. With the help of the midwife, a male lamb was born instantly. "Yang Yang" stopped barking, and the wet lamb opened his little eyes. The midwife cut its umbilical cord and disinfected it with iodine. 1 1: 58, the lamb gave its first crisp cry and struggled to stand up. "Yang Yang" seems to have no consciousness of being a mother. She only cares about her pace. No matter how hard the midwife tries, she just won't lick the baby. The midwife said, "There is still a lamb that has not been born."
12: 0 1, the lamb finally enjoyed the caress of its mother's tongue; 12: 06, it stood up trembling and went to find milk under its mother's stomach. At the same time, the sheep in Yang Yang flow badly; At 12, at 12, I vaguely saw white flashing from its swollen genitals, which was the little head of the lamb; 12: 08, midwifery begins; 12, 15, the second lamb landed successfully, and it was a female. Five minutes later, under the care of his mother, he also stood up.
The two lambs are the same color as their father-white. Brother's weight 1.4kg, height 24cm, length 23cm. Sister's weight 1.2 kg, height 23 cm, length 22.5cm.. Mother and child are safe, and the smooth production is beyond experts' expectation.
Professor Hua is pleased to announce that his brother's name is Huanhuan and his sister's name is Phoebe, which was personally named by the father of cloned sheep. As early as "Yang Yang" 10 months old, that is, when she was pregnant for 2 months, B-ultrasound found that she was pregnant with twins, but she didn't know it was twins. It is reported that the probability of sheep head twins is not as high as that of singletons, but it is not uncommon. Huanhuan and Phoebe are in normal health, and Yang Yang is full of milk, but she is short of water and weak, so she needs warm salt water.
In the sunshine, three pairs of mother and son "Yang Yang" made a picture of licking calves. 1 15, the placenta came out of Yang Yang's body, Huanhuan and Phoebe cleverly buried their heads in their mother's arms, and her mother was sleepy and slowly narrowed her eyes, looking intoxicated. ...
Special correspondent Bing Wang
I waited for 20 minutes and 63 hours.
—— The reporter interviewed the production notes of cloned sheep.
It was hot on August 5th.
After work, I received a message from Yangling China Clone Animal Base, saying that the somatic cloned sheep "Yang Yang" had prenatal symptoms at noon, with vaginal discharge of uterine suppository and poor appetite. It is estimated that it will be produced at night. We immediately drove to Yangling.
I arrived at the cloning base at 9 pm, but I didn't expect to be the first media to arrive, so I hurried to the front of the "Yang Yang" circle to check. At this time, "Yang Yang" seems to be normal, without any movement. In a short time, reporters from two other brother media in the province arrived one after another. As it is getting late, I don't know when Yang Yang was born. It seems that we can only spend the night in front of the sheepfold.
It's really hot, and the temperature can't drop at night. I'm not used to the smell of mutton that comes with the heat wave. I found a clearing, spread a newspaper on it, and then lay down. Mosquitoes are so powerful that people can't sleep.
It was hot on August 6th.
I didn't sleep well last night. The atmosphere is sultry and humid, and the newspaper under me is all wet. I always have to worry about "Yang Yang". I get up many times a night, while "Yang Yang" is busy sleeping. At 3 o'clock in the morning, I heard a sheep barking, sat up nervously and shouted, "Sheep! Yang Yang was born! " I was very surprised. Everyone ran to the sheepfold, but the cry didn't come from Yang Yang. I had a false alarm.
During the day, several media inside and outside the province, including CCTV, sent people. It was too hot and there were many mosquitoes and flies, and I didn't care. I am afraid of "Yang Yang", so I dare not leave at noon. In the middle of nowhere, I didn't have lunch. Yang Yang still hasn't moved. Experts estimate that "Yang Yang" will not be born today. They advised us to go back, saying that death was unscientific, but I still dared not go. Death is always safe. A colleague joked: "Yang Yang is putting on a star shelf."
Sleeping at night is a problem. Two media reporters returned to Xi 'an in the afternoon, got cushions, sheets and wind oil, and came back. We found two broken straw mats, which are better than newspapers.
Only the light in front of the "Yang Yang" circle was on all night, and everything was normal. Hot, all gay men are shirtless.
On August 7th, it was cloudy with light showers and turned cold.
Some media reporters couldn't hold on yesterday. They went back to Xi 'an or found a hotel to live in, saying that their wives had never been so cautious in giving birth to children, so they should inform us in time. Giving birth to a lamb is a flash, and no one can say when it will be born. It's been going on for so long, we can't give up.
Asking experts for knowledge about cloning has benefited a lot. Everyone was really tired of waiting, so they sent someone to buy a watermelon to quench their thirst, cut it and put it on the table, regardless of the fly bite, and they relied on instant noodles to satisfy their hunger at noon. There is an argument about what color lambs will be born in Yang Yang. Yang Yang is gray, and the handsome guy is white. They have equal opportunities to give birth to white sheep, gray sheep and flower sheep. The weather was gloomy, the smell of mutton seemed to fade, and there was a little shower in the afternoon. At 7 o'clock in the evening, the reporters who adhered together went to the city to eat, and the staff disappeared. The whole base was quiet, and the shower came again, and suddenly my heart was a little bleak. Our photographer said to me, "What if Yang Yang suddenly gives birth at this time? I have to deliver the baby myself. "
It is cool tonight. There are no mosquitoes when there is wind, so you can have a good sleep. How comfortable! Looking up is a dark sky, but the wind is too strong, and the plastic shed next to it is pattering, and the sound is very loud and a bit scary. I hope it won't rain at night, or we will be caught in the rain.
It turned cloudy and sunny on August 8.
I woke up early in the morning, propped up my head, listened to the movement of the sheepfold and took a look. Yang Yang seems to be wrong today. He doesn't sleep, fidgets and doesn't eat grass well.
It seems that it will be born today, and the experts are very nervous. God bless everything.
From 5: 00 noon to 12, "Yang Yang" gave birth, which was very smooth and the whole process was very fast. It took only 20 minutes before and after giving birth to two babies. I greeted the newspaper happily, and my colleagues on the other end of the phone couldn't stop being happy.
Just half an hour before the filming of "Yang Yang", several media reporters arrived one after another, catching up with this precious moment. We joked that it was unbalanced. After 63 hours, we got the same result as them. They are very lucky. In fact, we are happy in our hearts, and the most important 20 minutes have been kept by us. That's all that matters. After a few days' sleep, we all feel happy regardless of being covered in dirt.
