Abstract This study was aimed to explore the effect of using cassava as an amylopectin source in low protein (LP) diets on growth performance, nitrogen efficiency and postprandial changes in plasma glucose and related hormones concentrations of growing pigs. Three animal experiments were included in the present study. Treatments included corn-soybean meal LP (Corn LP), corn-cassava-soybean meal LP (Corn + Cassava LP), and cassava-soybean meal LP (Cassava LP). The in vitro digestion proved that Corn + Cassava LP and Cassava LP diets induced more rapid starch digestion and glucose release, compared with Corn LP diet. The results of animal experiments are as follows: Cassava LP diet caused the most rapid changes in plasma glucose and relevant hormones concentrations after a meal. And it decreased the concentrations of fasting plasma insulin, glucagon, and leptin concentrations compared with other treatments (P < 0.05). These modulationes above led to a strong desire to eat and increased feed intake and then weight gain in growing pigs fed Cassava LP diet. Besides, feeding Cassava LP diet caused diarrhea, increased noxious gas release from feces, and increased concentrations of fecal isobutyrate and isovalerate (P < 0.05). Compared with Corn LP group, Corn + Cassava LP group showed significantly decreased urinary nitrogen (P < 0.05) and improved post-absorptive amino acid utilization efficiency. In conclusion, the use of cassava as an amylopectin source in LP diets could modulate glucose absorption and related gut secreted hormones secretion, subsequently strengthened the desire to eat, improved growth performance, and enhanced nitrogen efficiency in growing pigs.
