Abstract

The study will be conducted through four experimental trials. In trial 1 and 2 will be evaluated the effect of the extrusion processing of the soybean or soybean meal at temperatures of 75°C; 115°C and 155°C, on nutritional value and ileal and total tract digestibility of feed nutrients and energy by piglets. For each trial, 40 male castrated pigs (8.0 kg initial BW) will be housed in a randomized complete block design experiment with 5 treatments, 8 replications per treatment, and 1 pig per experimental unit (cages for metabolic studies). In trial 3 the effect of increasing levels of extruded soybean meal replacing dietary blood plasma will be evaluated. In trial 4 the effect of increasing levels of extruded soybean replacing conventional soybean meal will be evaluated. In trial 3 192 and in trial 4 160 21-day weaned castrated male and female pigs (6.0 kg initial BW) will be used in a randomized complete block design experiment with 6 treatments, 8 replications per treatment, and 4 pigs per experimental unit (pen). During the 42-day experimental period will be evaluated pigs' growth performance, nutrient and energy digestibility, diarrhea occurrence, blood parameters, immunoreactivity of soybean proteins, histomorphometry and intestinal epithelium integrity and economic viability of these replacements.
