NEW CONCEPTS IN FEEDING Many aspects in swine nutrition deserve attention, but three that should have special significance to the producer include (1) the prob lem of low feed intake and growth rate during the summer months; (2) the incidence of porcine stress syndrome, and the pale, soft, and exudative (PSE) muscle that results; and (3) the most economi cal protein level for hogs that are destined for a grading program. Here are results of several studies that deal with each of these areas. Depression in hog performance during the summer months Producers have long recognized that pigs eat less and grow slower during hot weather. To reduce the problem, many producers have successfully changed the environ ment by adding drip coolers, eva porative coolers, or more fan capacity. And others have experi mented with nutritional changes, such as reducing fiber levels or adding fat. Recently, a study that shows promise was published by researchers at the University of Georgia. Their contention was that because pigs have increased respi ration rates during hot weather, the electolyte balance (sodium + potassium - chloride) is altered. Typical corn-soybean meal diets have a calculated electrolyte balance of about 80 meq/pound. In this study, the electrolyte balance in the six experimental diets range from about 11 to as high as 182 meq/'pound. As shown in Table 1, the opti mum balance in this experiment Pork Prose by Kenneth B.

Pigs affected with PSS usually have meat that is pale, soft, and exudative (PSE). When dietary vitamin E levels are increased from the typical level of 9 IU/pound to 118 IU/pound, the levels of enzymes associated with PSS are reduced. Harmful by products (ethane and pentane) from biochemical reactions are also reduced.
