Relative humidity in confinement housing may affect bacterial and viral concentrations. Con finement calf housing at 50 to 60% relative humidity had lower bacterial concentrations than similar housing at 80% relative humidity. Both ammonia and hydrogen sulfide gases can inhibit bacterial clearance mechanisms of the res piratory tract. Cold air may reduce tracheal mucociliary clearance. Udder health is influenced by a variety of environmental, contagious and host-defense factors. In many dairy breeds, contagious mastitis organisms have been controlled or elim inated. The low somatic cell count quarter is highly suscep tible to environmental organisms, especially during early lactation and during the first week of the dry period. Bed ding materials and other contact surfaces that have very high bacterial contamination may be associated with clini cal mastitis, with non-ag streptococci, or with gram negative Optimizing animal health is part of our mission Let us raise your heifers in housing designed specifically for heifers Structured feeding and health management programs to optimize heifer performance Detailed health records and monthly progress reports for you to monitor your calves Employees who specialize in calf care will pay attention to details every day Forages grown specifically for heifers, with rations and housing designed to heifer specs Up to 3 AI breedings and foot trimming costs are included in your fixed monthly charge “Ideal” height, weight, and health targets so you know what type heifer will come home Warranties for failure to grow, failure to breed, and death Reduction of animal units on your farm to assist in CAFO compliance Elba, NY Nicholville, NY (716)757-2440 (315)328-5110 Genesee County St. Lawrence County For one locked in price, this is what you can expect: Agway TSPF Heifer Farms “Raising the standard in quality dairy heifers ” sure. Dairy animals should have an environment that is clean, dry, and draft free; it should be “comfortable!” Pennington (1982) refers to two environments in the housing system, bi ological and physical. Managerial environment (attitude, skills, and knowledge) should be added to this list. Physical environment includes: Climate, Shelter, and Space; Biological environment includes; Feed, Water, Para sites, and Disease; Management environment includes: Atti tude of the caretaker and Facility affect on caretaker attitude. Housing system design, construction, and operation can impinge on all of these ares (Baxter, 1983, Light, 1973, Thompson, 1974). To encourage and facilitate good man agement, the housing facility must allow for convenient feeding, cleaning, milking, observation and restraint.
