How can steamed egg custard make it better?
The protein in the egg solidifies at 60 ℃ to 70 ℃. When steaming, the temperature of the outer layer of the egg will rise rapidly, resulting in a great temperature difference between the inside and outside of the egg. When the egg solidifies, the outer layer is dehydrated into a honeycomb. Therefore, to be a good steamed egg custard, we should master three points: 1. Temperature: stir the eggs in warm water and steam over medium heat after boiling. two。 Time: steam for 8 minutes after boiling. 3. Ratio: the ratio of egg juice to cold water is 1:2. After the water is boiled, put the egg on the steam compartment, and then boil it.

Three aspects of safe and efficient management of pigs in winter
Winter temperature is low, the weather is cold, which is not conducive to the normal growth and development of pigs, but also easy to make pigs sick. Therefore, the safe raising of pigs in winter should be carried out around the theme of keeping out the cold, and we should grasp the following three aspects: first, there are many ways to raise the temperature of the pig house, but there are four simple, economical and practical ways: 1. The open pig house is covered with plastic film. It is best to cover double-layer plastic film, although the cost is higher than single-layer plastic film, but the heat preservation effect is better. This method is appropriate.

Causes and Comprehensive Control measures of High Fever in Pigs
Recently, many pig farms have consulted about the causes of pig high fever and the technical problems of prevention and treatment. According to my own practical experience, the author puts forward some views for your reference. The cause of porcine high fever is essentially a pig disease caused by immunosuppressive pig disease, which is co-infected with a variety of viruses, bacteria and protozoa. Biological factors: classical swine fever virus, circovirus, blue ear virus, pseudorabies virus, eperythrozoon, toxoplasma, streptococcus, paratyphoid, mycoplasma, actinobacillus pleuropneumoniae, Haemophilus parasuis, pasteurella, etc.

Prevention and treatment of sulfonamides poisoning in ducks
Sulfonamides are a kind of drugs with a wide antibacterial spectrum, which can inhibit most Gram-positive and Gram-negative bacteria, as well as anti-coccidiosis. But if the medicine is not used properly, it will cause poisoning. 1. The cause of the disease is that when using sulfonamides, the dosage is too large and the course of treatment is too long, poisoning may occur. Sulfonamides with concentrations of more than 0.2% in drinking water and feed are toxic to ducks. Or those who are allergic to sulfonamides, or take too much dose by mistake, or the course of treatment is more than one week.

Prevention and treatment of bacterial endometritis in cattle and pigs
The uterine inflammation of cattle, pigs and other livestock is mainly the inflammation of endometrium, so it is called endometritis. Endometritis is usually a mucinous or suppurative inflammation of the uterine mucosa. And uterine myositis, uterine serositis, only in postpartum acute uterine inflammation may occur, but also very rare. Endometritis is a very common reproductive organ disease in female animals, which is divided into acute and chronic diseases. Acute occurs in postpartum, in dystocia, uterine prolapse, placenta infection after the pathogen; chronic mostly from acute to acute, or through mating infection. Female animals produce offspring

Bacterial Disease of Pigs-Bacillus anthracis
Anthrax is an acute septic infectious disease caused by Bacillus anthracis in livestock, wild animals and human beings. The clinical symptoms were septicemia, and the autopsy changes included poor blood coagulation, significant splenomegaly and hemorrhagic colloid infiltration under the skin and serosa. Pigs are sporadic, mostly subacute or chronic. Epidemic characteristics: Bacillus anthracis forms spores and can survive in the external environment for a long time. Pigs are infected through the digestive tract, and grazing pigs can be infected by finding food through arched soil.

Chinese-American biologists have successfully cultivated double-gene transfer cloned pigs
Famous Chinese biologist Yang Xiangzhong has worked with scientific research departments in Taiwan to produce the world's first cloned pig with human factor 9 and porcine lactoferrin, the University of Connecticut announced. The results of this study are expected to be used in the treatment of hemophilia. According to Yang Xiangzhong, a professor at the University of Connecticut, the study was conducted under extreme secrecy by a research team he chaired in cooperation with Taiwan's Institute of Animal Science and Technology. The first cloned pig was held at the Institute of Animal Science in Taiwan on February 15 this year.

Drug treatment of cecal Hepatitis in Sanhuang Chicken
A farmer raised 1000 Sanhuang chickens and 6 died suddenly at the age of 35 days. The daily feed intake of this group of Sanhuang chickens decreased, and a large group of chickens appeared with slight blood after the disease. in the next 10 days, the phenomenon of bloody stool, light yellow or light green increased, and the number of deaths increased, except for the symptoms of emaciation. Coccidial drugs were used continuously for 3 days to treat cecal coccidiosis, but the effect was not obvious. 1. Autopsy: the liver of the sick and dead chicken is characteristic, with a slightly larger volume and a round or irregular, slightly sunken ulcer on the surface.

Novice on the road-five elements of raising a good pig
Traditional pig farming emphasizes the four elements of "epidemic prevention, feed, disinfection and management". In addition to the above four elements, the current pig farming should also have a good health care system, that is, the fifth element. in the past, there was a great suffocation in the traditional arrangement, according to the actual situation of the current pig industry, we should have a new understanding of the arrangement of pig-raising elements. The management of traditional pig farming puts epidemic prevention in the first place, believing that pigs will not get sick as long as they are vaccinated. In fact, this practice is very unscientific because of the vaccine.
