Medicated Feed
Medicated feed is an American legal terminology. As of 2019, it was defined in 21 CFR § 558.3. History and synopsis The Animal Drug Availability Act 1996 introduced the term of ''new animal drug'', which should be applied in combination with traditional animal feeds such as hay and oats and barley. The FDA found it expedient to subdivide this term into two categories, according to the withdrawal period necessary to be observed prior to slaughter for animals about to enter the human food chain; and Prior to the enactment, only two categories of animal feed drugs existed: over-the-counter or prescription. The ADAA introduced Veterinary Feed Directive drugs. Medicated feeds are differentiated in § 558.3 from VFD rations, in that a licensed veterinarian is not required to supervise the feed product. Medicated feeds are available over-the-counter from agricultural suppliers. New animal drugs are the functional ingredients for medicated feeds. The distinction between medicated ...

Antibiotic Drugs
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity. Antibiotics are not effective against viruses such as the common cold or influenza; drugs which inhibit viruses are termed antiviral drugs or antivirals rather than antibiotics. Sometimes, the term ''antibiotic''—literally "opposing life", from the Greek roots ἀντι ''anti'', "against" and βίος ''bios'', "life"—is broadly used to refer to any substance used against microbes, but in the usual medical usage, antibiotics (such as penicillin) are those produced naturally (by one microorganism fighting another), whereas non-antibiotic antibacterials (such as sulfonamides and antiseptics ...

Neomycin
Neomycin is an aminoglycoside antibiotic that displays bactericidal activity against gram-negative aerobic bacilli and some anaerobic bacilli where resistance has not yet arisen. It is generally not effective against gram-positive bacilli and anaerobic gram-negative bacilli. Neomycin comes in oral and topical formulations, including creams, ointments, and eyedrops. Neomycin belongs to the aminoglycoside class of antibiotics that contain two or more amino sugars connected by glycosidic bonds. Neomycin was discovered in 1949 by microbiologist Selman Waksman and his student Hubert Lechevalier at Rutgers University. Neomycin received approval for medical use in 1952. Rutgers University was granted the patent for neomycin in 1957. Discovery Neomycin was discovered in 1949 by the microbiologist Selman Waksman and his student Hubert Lechevalier at Rutgers University. It is produced naturally by the bacterium ''Streptomyces fradiae''. Synthesis requires specific nutrient conditi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virginiamycin
Virginiamycin is a streptogramin antibiotic similar to pristinamycin and quinupristin/dalfopristin. It is a combination of pristinamycin IIA (virginiamycin M1) and virginiamycin S1. Virginiamycin is used in the fuel ethanol Ethanol (abbr. EtOH; also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound. It is an alcohol with the chemical formula . Its formula can be also written as or (an ethyl group linked to a ... industry to prevent microbial contamination. It is also used in agriculture, specifically in livestock, to accelerate the growth of the animals and to prevent and treat infections. Antibiotics also save as much as 30% in feed costs among young swine, although the savings fade as pigs get older, according to a USDA study.

Tylosin
Tylosin is a macrolide antibiotic and bacteriostatic feed additive used in veterinary medicine. It has a broad spectrum of activity against Gram-positive organisms and a limited range of Gram-negative organisms. It is found naturally as a fermentation product of ''Streptomyces fradiae''. Tylosin is used in veterinary medicine to treat bacterial infections in a wide range of species and has a high margin of safety. It has also been used as a growth promotant in some species, and as a treatment for colitis in companion animals. Mode of action Like other macrolides, tylosin has a bacteriostatic effect on susceptible organisms, caused by inhibition of protein synthesis through binding to the 50S subunit of the bacterial ribosome. Spectrum of activity Tylosin has a wide spectrum of activity against Gram-positive bacteria including ''Staphylococcus'', '' Streptococcus'', ''Corynebacterium'', and ''Erysipelothrix''. It has a much narrower Gram-negative spectrum of activity, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxytetracycline
Oxytetracycline is a broad-spectrum tetracycline antibiotic, the second of the group to be discovered. Oxytetracycline works by interfering with the ability of bacteria to produce essential proteins. Without these proteins, the bacteria cannot grow, multiply and increase in numbers. Oxytetracycline therefore stops the spread of the infection and the remaining bacteria are killed by the immune system or eventually die. Oxytetracycline is a broad-spectrum antibiotic, active against a wide variety of bacteria. However, some strains of bacteria have developed resistance to this antibiotic, which has reduced its effectiveness for treating some types of infections. Oxytetracycline is used to treat infections caused by ''Chlamydia'' (e.g. the chest infection psittacosis, the eye infection trachoma, and the genital infection urethritis) and infections caused by ''Mycoplasma'' organisms (e.g. pneumonia). Oxytetracycline is also used to treat acne, due to its activity against the bact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lincomycin
Lincomycin is a lincosamide antibiotic that comes from the actinomycete '' Streptomyces lincolnensis''. A related compound, clindamycin, is derived from lincomycin by using thionyl chloride to replace the 7-hydroxy group with a chlorine atom with inversion of chirality. It was released for medical use in September 1964. Uses Although similar in antibacterial spectrum and mechanism of action to macrolides, lincomycin is also effective against other organisms including actinomycetes and some species of ''Mycoplasma'' and ''Plasmodium''. However, because of its adverse effects and toxicity, it is rarely used today and reserved for patients allergic to penicillin or where bacteria have developed resistance. Clinical pharmacology Intramuscular administration of a single dose of 600 mg of Lincomycin produces average peak serum levels of 11.6 µg/mL at 60 min, and maintains therapeutic levels for 17 h to 20 h, for most susceptible gram-positive organis ...

Penicillin
Penicillins (P, PCN or PEN) are a group of β-lactam antibiotics originally obtained from '' Penicillium'' moulds, principally '' P. chrysogenum'' and '' P. rubens''. Most penicillins in clinical use are synthesised by P. chrysogenum using deep tank fermentation and then purified. A number of natural penicillins have been discovered, but only two purified compounds are in clinical use: penicillin G (intramuscular or intravenous use) and penicillin V (given by mouth). Penicillins were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci. They are still widely used today for different bacterial infections, though many types of bacteria have developed resistance following extensive use. 10% of the population claims penicillin allergies but because the frequency of positive skin test results decreases by 10% with each year of avoidance, 90% of these patients can tolerate penicillin.

Chlortetracycline
Chlortetracycline (trade name Aureomycin, Lederle Laboratories) is a tetracycline antibiotic, the first tetracycline to be identified. It was discovered in 1945 at Lederle Laboratories under the supervision of scientist Yellapragada Subbarow and Benjamin Minge Duggar. Duggar identified the antibiotic as the product of an actinomycete he cultured from a soil sample collected from Sanborn Field at the University of Missouri. The organism was named ''Streptomyces aureofaciens'' and the isolated drug, Aureomycin, because of their golden color. It is on the World Health Organization's List of Essential Medicines. Medical uses A combination cream with triamcinolone acetonide is available for the treatment of infected allergic dermatitis in humans. In veterinary medicine, chlortetracycline is commonly used to treat conjunctivitis in cats, dogs and horses. It is also used to treat infected wounds in cattle, sheep and pigs, and respiratory tract infections in calves, pigs and chickens ...
