06—Lancaster Farming, Saturday, May 10,1980 An eight-point program of good management can help prevent tail biting, a con stant potential problem in today’s swine operations. Tail biting tends to be somewhat seasonal, oc curring most often when the poorest tlunate conditions prevail and when ventilation in confinement facilities is the poorest. James D. Hedges, manager of swine research for the Wayne Feed Division of Allied Mills, Inc., recommends that producers take these eight preventive steps: Clip off the tails at birth. Stmt with clean facilities. Provide a balanced ration. Worm all pigs, whether on soil or not. Group pigs of the same THINK AHEAD... Read Futures Markets on Page 3. Program outlined to prevent swine tail biting size together, allowing a minimum of eight square feet per pig at market weight. Keep the sleeping area free of dampness and drafts. Be sure the ventilation systems in confinement houses are working well and that the air at the floor level is not stale. Watch closely for signs of nervousness, irritability, discomfort or actual chewing. The symptoms, whether they mclude tail biting, ear chewing, fighting or just restlessness, usually stem from the following con ditions: Subchnical disease problems; overcrowding m the pen; discomfort due to dampness or drafts; too little feeder or water space per pig. Also, slick or wet floors, so that pigs cannot move easily; stale air with high levels of ammonia and carbon dioxide gases; and poor nutrition due to im proper mixing of con centrates or improper use of complete feeds. The exact cause of tail biting is not know, Hedges explains. However, in many cases, it is an indication of bacterial buildup. The hogs may not be sick enough for a disease to be obvious to the producer.

Stress can result in an electrolyte imbalance. Hedges says. The predominant electrolytes are sodium and potassium, and, to a lesser extent, chloride ions. Thus, it’s a combination of low grade infection, elec trolyte imbalance, en vironmental changes and management practices that can lead to the tail bitmg problem. Once u occurs, Hedges recommends treating it in the following ways: Use a high level of • m w See Us First. WE'VE GOT WHAT YOU NEED medication in the feed.
