In recent years, the approach to animal health has switched from treatment of disease to prevention of disease. Cattle producers who realize that preventive care saves time and money in the long run are concerned about how man agement practices and environmental conditions affect animal health. One practice that produces stress in feeder cattle is re moving them from the familiar maternal environment to the competitive feedlot. Because this transition is unavoidable under most feeding systems, producers must devote consid erable effort to preparing animals for the change. Other stressful environmental conditions and procedures included the following: • dehoming • castration • weaning • sudden change in feed or water intake • loss of familiar surroundings • poor sanitation • exposure to new disease-producing agents • transportation • exposure to bad weather Most animals can withstand one or more of these stresses simultaneously and remain healthy because they have a va riety of self-regulating controls that keep their body system functioning normally. One such control, the immune system, protects the ani mals against potential disease-producing agents during pe- Invest Specializing Slatted pit for freestall barn Call for FREE estimates and see how affordable concrete walls can be.

Numerous stresses acting at one time may overwhelm the immune system, resulting in disease out breaks such as “shipping fever” in Pennsylvania feedlots. Nutritional Influence On Health Authorities generally agree that as much as 75 to 80 per cent of the health problems in feeder cattle are related to shipping. Once the cattle have adjusted to their new envi ronment, health maintenance should require less attention. But some conditions, such as intensive grain feeding alone, produce constant stress on cattle and can cause health prob lems at any time. Proper feeding requires knowledge of the nutritive value of feed materials, the nutritional needs of cattle, and the unique characteristics of ruminant digestion. For informa tion on nutritive value and nutritional needs, contact your county Cooperative Extension office. Like all ruminants, cattle depend on microorganisms in the rumen for digestion of forage and grain. These microor ganisms adapt to new feeding programs very slowly. When sudden changes are made in the diet, improper digestion re sults, reducing essential nutrients and producing abnormal rumen fermentation. Significant dietary changes should be made over a period of one to three weeks, not within a few days. Before you transport cattle, you should gradually adapt them to a feed ing program similar to the one they will receive after sale and shipment. Adaptation is not practical if animals are sold through an For all your Concrete Walls and Construction Needs (Turn to P*g« 70)
