Chinese-American biologist successfully breeds double-gene transfer cloned pig
The University of Connecticut in the United States announced recently that renowned Chinese-American biologist Yang Xiangzhong, in cooperation with the scientific research department of Taiwan, China, has bred the world's first double-gene transfer cloned pig carrying human coagulation factor IX and porcine lactoferrin. This research achievement is expected to be used to treat hemophilia. According to Yang Xiangzhong, a professor at the University of Connecticut, this research was conducted under extreme secrecy by his research team in cooperation with the Taiwan Animal Technology Research Institute. The first cloned pig was born on February 15 this year at the Taiwan Animal Research Institute

Long-finned koi successfully bred at aquatic improved variety trial farm
In Renhe Village, Bingcun, Meixian, there is a farmer named Qiu Dong. Two years ago, he suffered a natural disaster while growing golden pomelo, and nearly 400,000 yuan of investment was almost completely lost. He then switched to raising grass carp, but an 8-mu pond earned him only about two thousand yuan in a year, unable to make ends meet, and he fell into no small amount of debt, with his finances in dire straits. One day, a fisheries expert appeared and showed him a kind of fry, which brought a turning point in his life. Now, he has become a locally somewhat well-known "fish" farming specialist, with an annual net income of more than 20,000 yuan, and has led three or four neighboring relatively poor villagers to prosper together.

Three cloned pigs born successfully in Harbin
China's first cloned Northeast Min pig using adult somatic cells as nuclear donors has been born in Harbin. Three adorable black cloned piglets, just three days old, met with the media. This is also China's second successful cloned pig, following China Agricultural University. According to project leader Dr. Liu Zhonghua of the College of Life Sciences at Northeast Agricultural University, the difference between their cloned Northeast Min pig and previous cloned pigs lies in the use of adult somatic cells as nuclear donors; the donor nuclear cells were taken from a 3-day-old Northeast Min piglet

Qinghai Successfully Introduces a New Fish Species from Russia
The new fish species introduced from Russia for trial breeding - the whitefish (Coregonus peled) - will be promoted on a large scale in Qinghai Province. The introduction of this "foreign fish" has not only broken the previously rather monotonous aquaculture pattern in the province, but also moved Qinghai's fisheries one step closer to the international market. In order to make the whitefish breeding and cultivation technology more mature in the province's aquaculture sector, Qinghai Province recently invited Alexander Ivanovich Litvinenko, president of the Research Academy of the Siberian Fisheries of the Russian Federation and academician of the Russian Academy of Sciences, to visit Qinghai for inspection and technical analysis, and to provide market information.

How to raise pullets for egg production successfully? Detailed explanation of key technical measures
When chicks are 7 weeks old, they are moved into the growing house and enter the growing stage. Whether this stage is successful or not largely determines the physique and laying performance of laying hens after sexual maturity. Therefore, to raise high-yielding replacement laying hens that meet breed requirements, the key link is to do a good job in the feeding and management of growing chickens. 1. Do a good job in disinfecting the environment inside and outside the chicken house to create a relatively safe living environment for the flock. Many diseases on laying hen farms are caused by horizontal transmission. Therefore, disinfecting the chicken house, the surrounding environment, and the chickens themselves to cut off the links of horizontal disease transmission is an effective way to control disease occurrence and reduce chicken deaths. The specific technical measures taken are: ① Two weeks before introducing the chickens, first thoroughly clean and wash the chicken house, then wash and disinfect it with disinfectants such as Baidusha or Aidifu. ② Use formalin plus potassium permanganate for fumigation disinfection at a ratio of 30 ml plus 15 g, keep it sealed for 1-2 days, and pay attention to increasing the temperature and humidity of the chicken house to improve the disinfection effect. ③ One day before introducing the chickens, spray disinfect once with Youlüjing or iodine preparation disinfectant, and disinfect the floor with a 1%-2% caustic soda solution. ④ After introducing the chickens, carry out disinfecting with chickens present 1-2 times per week, alternating disinfectants to avoid the emergence of drug resistance. In seasons with frequent disease, disinfect 2-3 times per week. In hot summer, disinfect once a day, which can also play a certain role in preventing heatstroke and cooling.
