1. Cage specifications: Cultured black fish cages should not be small, usually with 15 to 33 square meters of small cages, mesh specifications depending on the size of black fish and bait fish, not drilled prevail. 2. Stocking densities and specifications: Stocking specifications of 5 to 150 grams per square metre, and 8 to 16 tailed black fish species, requiring that the black fish species in the same box be of uniform specifications so as not to kill each other if the feed is insufficient. The stocking work should be completed before the end of April. If the stocks are not concentrated, they can be stocked one after another. 3. Black fish species selection: At present, most of the black species come from natural sources. Therefore, when selecting black species, it is required to select the species to be caught by fishing nets such as dip nets, cormorants and knapsacks. Most of the caught fish caught by hook fishing should not be used. 4. Set habitat shelters: stock some of the plants in the tank, covering an area of ​​no more than 70%, as a blackfish habitat and shelter. 5. Feeding method: black fish is a carnivorous fish, eat live fish, live shrimp, quail, can not be fed fish with hard thorns. Generally from the end of April, the amount of bait is 2% to 5% of the total weight of blackfish, and the size of bait fish can be swallowed by blackfish. The feed coefficient is controlled at around 4 in the whole year. 6. Anti-escape measures: The water part of the cage should be kept at about 1 meter, and cover nets must be added. The width of the cover is about 0.5 meters to prevent the blackfish from fleeing. In addition, we must always check whether the net clothes are bitten by water mice. Veterinary Drug Preparation For Poultry
Medicine for poultry.
Medicine for cattle,including antibiotics, hormones, feed, vitamin nutrients, etc.
Veterinary drugs refer to substances (including drug feed additives) used for prevention, treatment, diagnosis of animal diseases or purposeful regulation of animal physiological functions.
Veterinary drugs can be roughly divided into four categories: â‘ general disease prevention and treatment drugs; â‘¡ Drugs for prevention and treatment of infectious diseases; â‘¢ Drugs for prevention and treatment of internal and external parasitic diseases; â‘£ (including growth promoting drugs). Except for the biochemical immune products (vaccine, vaccine, serum, antitoxin, toxoid, etc.) for the prevention and treatment of infectious diseases, as well as special veterinary drugs for livestock and poultry parasitic diseases and growth promoting drugs, the rest are the same as those for human use, but the dosage, dosage form and specifications are different. It has long been widely used in the prevention and control of livestock and poultry diseases.
Our business covers Africa, the Middle East, Central Asia and Southeast Asia. Respiratory Infections Tylosin Doxycycline,Campylobacter Tylosin Doxycycline Powder,Salmonella Tylosin Doxycycline Powder,Doxycycline 20% Water Soluble Powder Shandong Unovet Pharmaceutical Co.,Ltd. , https://www.unovetcn.com
More than 20 kinds of veterinary drugs are commonly used, such as analgin, amoxicillin, florfenicol, ceftiofur, oxytetracycline, chlortetracycline, bacitracin, salinomycin, monensin, colistin, etc. 60% of antibiotics were used in chemotherapy; 40% is used as feed, which can not only prevent infectious diseases, but also promote the growth of livestock and poultry and improve the utilization rate of feed.
Among the Antiparasitic Drugs, in addition to the common anti helminth drugs (mebendazole, levamisole, thiadiazine, etc.), anti schistosomiasis drugs (antimony agent, nithiocyandiamide, praziquantel, etc.) and anti tapeworm drugs (niclosamide, etc.), the special anti Fasciola hepatica drugs (nitrochlorophenol, trichlorobenzole, etc.), Trypanosoma, and pyroplasmosis drugs (antracel, suramin, chloramphenicol, etc.) for livestock and poultry are also used Imidacloprid and other insecticides (organophosphorus insecticides). A macrolide antibiotic was found to have a significant killing effect on parasites such as gastrointestinal nematodes, Dermatophagoides, blood sucking lice, especially Sarcoptes scabiei. Coccidiosis is a serious threat to the safety of chickens and rabbits. There are more than 30 kinds of commonly used anticoccidial drugs, including synthetic drugs (such as chlorobenzoguanidine, changshanone) and antibiotics (such as monensin, salinomycin), which are often used alternately.
Biochemical immune products are mainly used to prevent animal anthrax, brucellosis, anthrax, salmonellosis, and a variety of viral infectious diseases.
Injections are commonly used in veterinary drug preparations, but their specifications are several times larger than those for human use. Oral veterinary drugs are usually in powder or microcapsule form, as feed additives, mixed into the feed for free feeding of livestock and poultry. Anabolic hormone can increase the benefit of raising livestock and poultry. It is mainly made into implant for subcutaneous implantation. Transdermal preparations and medicated baits for aquaculture are emerging.
