Marker-assisted selection is the general direction of future breeding
Conventional breeding methods have limitations such as genetic variation and genomic hybridization. In principle, these limitations can be overcome by genetic engineering methods such as recombinant DNA. By using these methods, the genes with definite function can be cloned and the genes can be fast and high.

Can canine distemper infect people?
Recently, there is a high incidence of canine distemper. Many pet hospitals treat more than a dozen canine distemper patients every day. Therefore, experts remind pet parents to vaccinate their pet dogs as soon as possible. Wei Rensheng of the pet hospital said: "recently, pet hospitals have increased the number of dogs suffering from canine distemper, which is related to the increase in dog walking after the rise in temperature." The reason is that the dog's feces cause cross-infection after defecating everywhere. In addition, many citizens only vaccinate their pet dogs against rabies, but not against infectious diseases. " According to relevant understanding, cure canine distemper

Problems needing attention in breeding quail seedlings
After coming out of the shell, the young quails were raised in cages and heated by a coal stove with a smoke exhaust pipe. the temperature was 32 ℃ at one day old, then decreased by 0.5 ℃ a day, and was de-heated when the air temperature was above 20 ℃ at 20 days old. Broiler feed for small quails (with a crude protein content of not less than 22%) until it is laid

Processing technology of caviar and roe
The ovaries of all kinds of spawning marine fish, shellfish and freshwater fish can be used as food, and fish eggs are considered to be a very nutritious food in many parts of the world, with high protein content, less raw material pollution and good taste. Therefore, fish egg products are very popular in the world market. First, caviar processing the term "caviar" commonly refers to fish eggs produced in a special way. Black caviar used to be a royal delicacy abroad, but now it is fashionable and fond of delicacies.

Application of Interferon in the treatment of Infectious Canine Hepatitis
Infectious canine hepatitis is an acute septic infectious disease caused by adenovirus. It was characterized by necrosis in the center of hepatic lobule, intranuclear inclusion bodies in hepatic parenchyma cells and cortical cells, and prolonged bleeding time. Infectious canine hepatitis does serious harm to dogs and causes great economic losses to the dog industry. The virus has strong resistance and can survive in the soil for a long time under the condition of low temperature. it still has pathogenicity after 10 to 14 days, and can survive in the dog nest for a long time. Sick dogs and recovered dogs with virus are the source of infection of the disease, and their blood secretions and excretions

Research Progress on Detection Technology of Porcine circovirus
Porcine circovirus disease is a kind of viral infectious disease caused by porcine circovirus (PCV) infection and characterized by immunosuppression. the clinical manifestation is mainly caused by postweaning multisystemic wasting syndrome of piglets caused by PCV-2. In this paper, the detection techniques of the virus at home and abroad in recent years, including virus isolation, electron microscopic observation, polymerase chain reaction, indirect immunofluorescence test, immunohistochemical technique, enzyme-linked immunosorbent assay, in situ nucleic acid hybridization test and so on.

The first case of cloned piglet in China was revealed
After more than a year of scientific and technological research, the research group led by Professor Li Ning of China Agricultural University finally got a return on August 5, 2006 at Minghui Pig raising Company in Sanhe City, Hebei Province. China's first self-completed somatic cloned pig was born successfully, and its birth filled the gap in this field in our country. China is the seventh country to have obtained somatic cloned offspring of pigs. At 10:50 on August 5th, at Minghui Pig raising Company in Sanhe City, Hebei Province, one weighed 1130 grams and the coat color was black and shiny.

Application of phytase in diets of pigs and chickens
Phytic acid or phytate is common in plant feed, and most of the phosphorus exists in the form of phytate phosphorus. Phytic acid can form a stable complex with metal ions such as calcium ion, iron ion, zinc ion and copper ion, and can also combine with protein and starch, reducing the activities of endogenous amylase, protease and lipase. The digestibility of nutrients decreased significantly. Phytic acid is not absorbed by monogastric animals, and most of it is excreted in the form of feces, which not only greatly reduces the utilization rate of phosphorus, but also causes environmental pollution, especially water pollution.
