1. The energy contained in the digestible nutrients of the feed is called digestive energy.
2. The button-shaped ulcer of swine fever belongs to: fibrinous inflammation.
3. The intermediate host of Schistosoma japonicum is: snails.
4. The main organs of drug excretion are the kidneys and biliary tract.
5. The concentration of normal saline is 09%.
6. Porcine infectious pleuropneumonia: it is a respiratory infectious disease that often occurs in pig farms, and the mortality rate of acute pleuropneumonia is very high.
The disease is very contagious and is characterized by symptoms and lesions of pleuropneumonia. Pigs of different ages are susceptible, and the mortality rate of pigs aged 4-5 months is more, and sick pigs and infected pigs are the source of infection of this disease. The pathogen is mainly found in the mucous membranes of the respiratory tract and is transmitted through airborne droplets, which are most susceptible to contact infection under the conditions of intensive feeding in large groups. The morbidity and mortality rates of the first disease herd were high, and the morbidity and mortality decreased significantly after a period of time. But after a period of time, there is a possibility of an outbreak of epidemics, with an incidence of 85%-100%。The mortality rate is 04%-100%, when the pig herd is severely stressed, it can promote the occurrence of this disease.
Clinical signs: Acute illness of pigs began to increase their body temperature to 415 or more. Depressed, not eating, followed by difficulty breathing, mouth breathing, often standing or dog sitting posture, foamy discharge from the mouth and nose, ears, nose and limbs** blue-purple, if not timely** often suffocated within 1-2 days. If symptoms begin to subside and can last more than 4 days, they can gradually become ** or become chronic. At this time, the body temperature of the sick pigs is not high, intermittent cough occurs, growth retardation, and many pigs begin to show chronic symptoms.
7. Swine flu is prone to occur when the seasons change, and swine influenza is an acute, highly contact respiratory infection caused by swine influenza virus, which has a rapid onset and rapid spread, often occurs suddenly, and quickly infects the entire pig herd, with an incidence rate of up to 100%. The mortality rate is low, and it is easy to develop secondary infections with other pathogens after the onset of the disease. The disease is a zoonotic infectious disease, and during the epidemic, the spread of the virus should be avoided as much as possible, and personnel protection should be done at the same time.
Swine flu is more likely to occur in the season when the temperature fluctuates and the temperature difference between day and night is large, and the course of the disease is generally about a week. Sick pigs, ** infected pigs and chronically infected pigs are the source of infection of the disease, and the virus is present in the nasal fluid, tracheal and bronchial exudate, and pulmonary lymph nodes of affected pigs, and is mainly transmitted through the respiratory tract. Pigs of all ages, breeds and sexes are susceptible to infection, with high morbidity, low mortality and rapid transmission, usually 2-3 days to spread throughout the herd. Secondary or mixed infection with Actinobacillus pleuropneumoniae, Pasteurella and Streptococcus will have serious consequences.
After being infected with the disease, the whole herd of pigs became ill at the same time within 2-3 days, and the body temperature rose to 40-41, and in severe cases it was as high as 42. The clinical symptoms are mental depression, decreased appetite, or even abolition, lying on the ground, unwilling to move, often limp when forced to walk, dyspnea, abdominal breathing, paroxysmal cough, mucous and purulent discharge from the mouth, eyes and nose, blood in the secretions, flushing of the conjunctiva of the eye, growth arrest of sick pigs, and abortion often occurs in the later stage of pregnant sows. Swine flu can cause a decrease in the immunity of pigs, leading to the secondary development of other swine diseases.
8. Bupleurum chinensis is often used as an anti-surface medicine, which has the effect of publishing and li, soothing the liver and relieving depression and lifting the positive, and has a good effect on anal prolapse and uterine prolapse caused by insufficient Zhongqi. Astragalus has a history of 2,000 years of medicinal use, and is a well-known qi-tonifying drug, which has the functions of replenishing qi and raising yang, fixing the surface and stopping perspiration, diluting water and reducing swelling. Detoxification, purulent and spasmodic muscle-building effect.
Traditional Chinese medicine prolapse is caused by insufficient middle qi and prolapsed organs, mostly due to congenital dysplasia, acquired nutritional insufficiency, long-term diarrhea and cough, etc., which leads to the damage of healthy qi in piglets caused by weakness, and the lack of middle qi, resulting in prolapse of organs and clinical symptoms of anal prolapse.
9. Deworming: 15 days before farrowing, sows should be fed with albenda or fenbenda frustration for 7 days.
Ectoparasites can be sprayed with low-toxicity organophosphates or pyrethroids and resprayed every 7 days. Splashing agents (extended-release, transdermal administration) can also be used.
10. Due to severe damage to deep tissues, infection with anaerobic bacteria causes gas gangrene.
