Dietary Protein Source

A total of 672 male 7-day-old broiler chicks were used in a 14-day cage study to evaluate the interactive effects of dietary protein source and exogenous protease on nutrient digestibility and intestinal physiology. Birds were fed a common starter diet from Days 0 to 7 and switched to experimental diets from Days 7 to 21. Four corn-based dietary treatments were arranged in a 2 × 2 factorial arrangement with factors being two major sources of protein [soybean meal (SBM) or canola meal] and diets offered with or without exogenous protease. Bodyweight gain and gain:feed were higher (P < 0.001) in the diets based on SBM than in the diets based on canola meal and protease was more effective (P < 0.05) in enhancing performance in SBM-based diets. Ileal nitrogen digestibility was increased (P < 0.01) by protease use in diets based on both major protein sources. However, ileal digestible energy was increased (P < 0.05) by protease only in the SBM-based diet resulting in an interaction between diet protein source and exogenous protease. Jejunal villus height tended to be higher (P = 0.07) in birds fed diets based on SBM and protease use increased (P < 0.05) crypt depth only in the SBM-free diets resulting in a significant interaction between protein source and protease use. Patterns of gene expression in jejunal tissue suggested that both dietary protein source and exogenous protease influence the expression of genes responsible for mucin secretion, amino acid transport and immune functionality in an age-dependent manner. It can be concluded that SBM may be a more suitable protein source for young broiler chickens than canola meal and that use of canola meal as a major source of dietary protein may have negative implications for performance, nitrogen digestibility and gut health. However, exogenous protease appears to be more compatible with substrates presented by SBM than is the case for canola meal based on advantages conferred in nutrient digestibility and performance. The beneficial effects of exogenous protease may be linked both to enhanced protein and energy digestibility and improved gut morphological characteristics, secretory and absorptive dynamics and immune resilience.

Dietary Protein Source

Two experiments were conducted to evaluate the involvement of dietary protein and short-term chilling on the incidence of diarrhea and on transit time of digesta in pigs weaned at 3–4 wk of age. The three protein sources used were buttermilk powder (BMP), soybean meal (SBM) or pea protein concentrate (PPC), which provided 85% of the dietary protein. In exp. 1, 72 pigs were exposed to a 16 °C decrease in ambient temperature for 8 h on day 4 of a 9-day feeding trial; 72 pigs were not chilled. The pigs on the PPC diet gained less (539 g) (P < 0.05) than pigs on BMP (1183 g) or SBM (952 g) although intakes were similar. Neither diet nor chilling affected fecal moisture content or the incidence of diarrhea. The PPC ration increased (P < 0.05) transit time (slowed rate of passage) on day 8. Chilling on day 4 decreased (P < 0.05) transit time (18.7 vs. 25.6 h) on that day. Neither protein source nor chilling caused differences in total or coliform bacteria isolated from fecal samples on blood agar or MacConkey's agar. In exp. 2, eight chilled and nine control pigs were euthanized and the quantity of three markers in six segments of the gastrointestinal tract was determined. The PPC diet passed more slowly than the other diets. In chilled pigs, the chromic oxide front was closer to the anus, indicating an increased rate of passage. It was concluded that the severity of the cold exposure was not suffficient to induce diarrhea and that there was no interaction between the effects of chilling and of dietary protein. There was, however, a tendency for chilling to increase the rate of passage of digesta which could have an additive effect on the severity of nutritional diarrhea. Key words: Pigs, weaning, diarrhea, protein, cold, transit time.
