DON’T GAMBLE WITH SALMONELLA
Take these steps to prevent Salmonella from becoming a problem on your dairy.
• Adopt an all-in/all-out calf- and heifer-raising facility.
• Maintain a closed herd or make purchases from low-risk herds.
• Manage new additions to the herd to minimize stress and infection of residents.
• Minimize stress by feeding good rations, providing adequate time and space for transitions and maintain clean, uncrowded maternity pens.
• Use different facilities for calving cows and sick cows.
• Avoid adult-to-calf contact.
• Isolate heifers from the lactating herd.
• Disinfect waterers in high-risk areas (dilute with bleach twice daily).
• Scrape manure, remove organic debris, disinfect clean, non-porous surfaces and expose to sun or UV light.
• Minimize fecal contamination of feedstuffs, feeding surfaces, water troughs and equipment.
• Do not use manure-handling equipment to handle feed and keep manure-handling equipment out of feed lanes or feed storage areas.
• Make certain that feed delivery vehicles do not travel through manure or across manure-scraping lanes.
• Drain and level areas that collect water.
• Allow no access to pond water or feeding areas cohabited by birds and waterfowl.
• Isolate the entire group in which affected cows co-mingle. There should be no shared bunk spaces, water source, feeding or manure-handling equipment.
• Leftover TMR from the cows should not be fed to the heifers.
• Segregate Salmonella test-positive cows at calving.
• Do not use colostrum or milk from test-positive cattle.
• Control rodents, birds and feral cat populations.
• Be vigilant about waste management, control of effluent, and the distribution of recycled flush water.
• Pasteurize waste milk and colostrum fed to calves. Even refrigeration will contain growth of Salmonella in contaminated colostrum and waste milk.
• Control flies throughout the dairy with common fly-control methods.
• Restrict visitors and insist on biosecurity measures (such as clean boots and clothing) by all who enter the facility, including the herd veterinarian.
• Disinfect calf-feeding utensils and oral-treatment equipment.
• Wash and disinfect boots regularly and change and launder work clothes daily. Ideally, boots and work clothing should be left on the dairy.
• Sanitize transport trailers, particularly when hauling young calves.
• Vaccinate. Vaccination will not stop infection, but selected vaccines may reduce the severity of infection and curtail the mortality rate. Vaccines are no substitute for management to reduce contamination and decrease stress.
Are you gambling with your herd's health?
