Broken hundred pounds fat sister
Officially debuted the first real "Little Mermaid"
There are three species of manatee living in the world: the Amazon manatee, the West Indian manatee and the West African manatee, all of which are listed on the IUCN Red List of Threatened Species, and the West African manatee is listed as a "vulnerable" species. The mammary glands of female manatees grow at the base of the pectoral fin, which is the human arm socket, and have been mistaken for "mermaids" by ancient sailors because the cows hold their cubs on their chests for feeding.
West African manatees are sexually mature at 3 years old, and males are generally sexually mature at 9-10 years old, and due to their low estrus and gestation period of up to 13 months, the low breeding rate has become a recognized world problem. On May 8 last year, the male manatee baby "Bill" was successfully born in Zhuhai Chimelong Ocean Kingdom, which was the first case in China. Shortly after the little "Bill" celebrated his first birthday with the majority of tourists, the Zhuhai Chimelong Ocean Kingdom Manatee family once again welcomed new members. According to Zhuhai Chimelong marine animal expert Zhong Yifu, the West African manatee mother "xixi" gave birth to the first real "Little Mermaid" in Zhuhai Chimelong, creating a new miracle and record.
According to reports, "xixi" reached a climax of estrus in March last year, frequent mating occurred, and "nose bubbling" often began in April, and the nursery staff initially judged that it was conceived and included in the scope of key observation. Because "xixi" has a very sensitive temperament, a stronger sense of self-protection after pregnancy, and even does not allow the nurseryman to approach, so it is impossible to complete the b ultrasound examination, until her stomach slowly bulges, which once again proves that the pregnancy test method explored and summarized by the nursery team is accurate.
The fattest cow mother gave birth in September
The world's first verification of two big cattle pregnancy test accuracy rate of 100%
After the successful breeding of the first West African manatee, the nursery team found for the first time that the nose of the manatee mother began to bubble up a month after mating, and successfully verified that another West African manatee mother "guagua" also took over the baton "good pregnancy" and will give birth in September based on the large number of observation data accumulated by "Bill" when she was still in the womb. It is worth mentioning that the two baby manatees that have been born were born in the outer exhibition area, which means that visitors have the opportunity to witness the whole process of the birth of the third "Little Mermaid" of Zhuhai Chimelong.
Thanks to the first-hand experience summary before and after the birth of "Bill", Zhuhai Chimelong realized the world's first discovery of two large cattle pregnancy test method - "nose bubble" pregnancy test method and "circle" pre-delivery method, the current accuracy rate and survival rate are 100%, for the three existing manatees known as "the most little-known manatee" West African manatee breeding, explore the unique successful experience. It is reported that another female manatee in Zhuhai Chimelong is expected to give birth in September. This means that Zhuhai Chimelong has successfully broken through the breeding problem of low fertility of rare West African manatees and will usher in the largest display population of newborn West African manatees in the country.
