Hog operation disinfectants discussed NEWARK, Del Cleanup and disinfection are two vitally im portant parts of any swine management program. Most producers are more familiar than they would like to be with the cleanup process. Disinfectants are another matter. Why should you use a disin fectant 9 “It’s cheap insurance,” says University of Delaware ex tension livestock specialist Ken Kephart. “We often talk about disease build-up.

Montgomeryville PA (215)699-5871 Newcastle, DE (302)652 3028 Lancaster Farming, Saturday, March 3,1984—D25 Formaldehyde is probably the most effective disinfectant available, Kephart says. It kills nearly all types of microbes and viruses under a wide variety of conditions. Unfortunately, at high concentrations its fumes are very irritating. When used as a gas it’s an excellent fumigant, but it must be used with caution. Solutions of formaldehyde also provide good germicidal activity and are safer to use than the gas. Creosols and phenols, like for maldehyde, can produce ob jectionable odors. That's especially true with creosol, the specialist says. But they have excellent resistance to organic debris. So if a swine facility con tains a lot of wood or hidden crevices, these compounds might be the best choice. They also provide good results in foot baths. Quarternary ammonium compounds are not recommended for disinfecting livestock facilities, since organic matter quickly inactivates them. They have limited effect on viruses, fungi and spores. They do work well for sanitizing dairy and food handling equipment. But since these compounds are neutralized by soap, be sure that surfaces are rinsed well before using the quarternary ammoniums. lodophors are a combination of iodine and detergents. They aren’t very effective in the presence of organic material. And they provide only limited activity against viruses and salmonella bacteria. But the lodophors are non-irntating and rarely cause skin reactions. For producers who wash and disinfect sows before farrowing, one of the lodophors is a good choice. Sodium hydroxide provides good germidical properties under most conditions. And it’s cheap. But it’s also very caustic and can cause serious burns, Kephan cautions Use accordingly. “So, to get the most from your disinfectant dollar, think about how and where you plan to use the disinfectant,” he advises “Remember that good sanitation is a must An effective cleanup will remove 95 percednt of the con tamination. And it allows the disinfectant to penetrate and do the job you expect.” (Esr% BREAKING MILK RECORDS! Lancaster Farming Carries DHIA Reports Each Month!
