Chitin and Chitosan in Animal Husbandry


Positive bacteria, negative bacteria were significantly inhibitory effect. Can be used for the prevention and treatment of various infectious diseases, with the T 140 test method for hidden adult cow mastitis, and the results showed that chitosan treatment of bovine subclinical mastitis does have the effect and yield increase, and the effect better than levamisole, Chinese herbal bath. In the water with different concentrations of chitosan, inhibited Aeromonas and Vibrio growth and reproduction, increase the survival rate of larvae, and promote growth of shrimp. Antibacterial effect of chitosan can be used for pork, eggs and fresh fruit. Lower blood lipids, improve livestock and poultry meat animals Chitosan can reduce blood fat and cholesterol. Because of its composition dextran amine in the price of ammonium ion with 4-chain,[link widoczny dla zalogowanych], it has a high anion exchange capacity, can bind bile acids, preventing bile acid circulation, reduces fat absorption, thereby reducing the amount of body fat deposition. In the feed supplemented with 2% chitosan, can change the chicken in the composition of unsaturated fatty acids and can reduce cholesterol in chicken, and do not reduce feed utilization. Other features of chitin and chitosan can be organic to promote liver and intestinal absorption of harmful toxins from your body, alleviate or reduce the load of the liver detoxification, thus helping protect and enhance the role of the liver. In addition there is bleeding chitin, anti-inflammatory effect, can be used for surgery. Chitin exists in crustaceans, insects and fungi. China's rivers, lakes and more large area, resources are very rich in crustaceans, in addition to providing fresh food for people,[link widoczny dla zalogowanych], but also for the people left a lot of resources for urgent development of chitin. Chitin, chitosan applications is very broad. There are many reports abroad. China's late start in this regard, especially in the application of animal husbandry has not yet received enough attention so far has not been a lot of application in animal husbandry, I believe that with further research, in the near future, chitin, chitosan for the development of animal husbandry has played a huge role. (Jinan, Hong Ji Tong Pharmaceutical Co., Ltd. Shandong Jinfeng Zhen CYTOCHEMISTRY Chi Standard 250002 Group Technology Center, Kim Tae Chang is the winner) of the livestock and poultry products are many kinds of livestock and poultry products disinfection and sterilization methods are many, are the product of several livestock and poultry as a disinfection method Introduction. Ethylene oxide fumigation method adaptation suspicious object was anthrax,[link widoczny dla zalogowanych], foot and mouth disease, Salmonella, Brucella dry contaminated hides, wool, feathers, velvet products. Methods skin or hair bundle packages, such as orderly pile velvet bag to the sterile container (plastic film tent or large metal sterilization containers), the code into a pile shape, but no higher than 2m, the appropriate distance between the lines, in order to facilitate gas penetration and personnel operations. By 0.4 ~ 0.7kg/m3 pass into the ethylene oxide gas sterilization 48h. At this point to maintain disinfection room temperature 25 ~ 40 ��, relative humidity of 30% to 50%. After disinfection, open the seal, ventilation 1h. Peracetic acid immersion disinfection method to adapt to object to any pathogenic microorganisms suspected contamination of fresh poultry skin, salt, wet skin, hair, feathers, wool and bone, hoof, horn and other products. Method of freshly prepared 2% and 0.3% peracetic acid solution. Will be disinfected skin, hair, feathers, velvet immersed in 2% solution; bone, hoof, horn immersed in 0.3% solution, soaking 30min, the solution to be higher than items side 10cm. Remove, wash with water after drying. Formaldehyde solution (formalin) fumigation method for objects suspected contamination of pathogenic microorganisms normally dry hides, hair, feathers and velvet. Method of sterilization with ethylene oxide fumigation, but the total volume of the disinfection chamber does not exceed 10m3, sterilization room temperature should be 50 ��, humidity conditioning at 70% to 90% formaldehyde solution evaporation by heating 80 ~ 300ml / m the amount of ,[link widoczny dla zalogowanych], which leads to formaldehyde gas disinfection 24h. Formaldehyde aqueous solution immersion disinfection method is generally applicable targets for suspected pathogen contaminated animal bones, hooves and horns. Method of freshly prepared 1% formaldehyde solution, and then bone, hoof and horn immersed into the solution, 30h, remove, rinse with water after the dry. 0Co radiation sterilization law applies to suspected contamination of valuable fur of any pathogenic micro-organisms for disinfection, a dose of 250rad (rad). Peracetic acid or coal phenol soap (to Su children) solution for spraying disinfection to be disinfected the scope of application of bone,[link widoczny dla zalogowanych], hoof and horn packaging or other packaging. Methods freshly prepared solution of 0.3% or 3% peracetic acid phenol coal spraying disinfectant soap solution, the amount of 0.5L/m3. High-pressure steam sterilization method is suitable for suspicious objects contaminated anthrax, foot and mouth disease virus, Salmonella, Brucella animal bones, hooves and horns. Methods bones, hoofs and horns into the pressure cooker, the cooking to the bone unglued or skim pm.
