Effects of Various Dietary Nutrient Levels on the Incidence of Colibacillary Diarrhea in Pigs: Intestinal Ligation Studies1

Abstract

Four experiments employing a ligated intestinal loop technique were conducted to study the effect of various nutritional factors on the incidence of colibacillary diarrhea in early weaned pigs. These results showed that the two strains of Escherichia coli (strains K1261 and K1362) used caused more (P<.05) fluid accumulation in ligated intestinal segments than control segments and thus can be considered enteropathogenic. In these studies, neither the level of dietary protein (12% or 22%) nor the source of dietary energy (corn, corn plus 20% glucose or corn plus 30% lactose) had any effect on the incidence of colibacillary diarrhea when measured by the amount of fluid accumulation per centimeter of loop length. The addition of 20% oats to a normal 18% protein corn-soybean meal diet resulted in less fluid accumulating in ligated intestinal segments, especially in the absence of the two strains of E. coli (control segments), as compared to those values observed with the control diet. The protein content of loop fluid was related to the dietary protein level but was not affected by the type of loop inoculation. The sodium and potassium contents of loop fluid were similar for all loops regardless of dietary or loop treatments, which suggests that the pigs were able to maintain constant electrolyte balance in the gut lumen even with large amounts of fluid accumulation.
