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.

Nutrient Metabolism

Using alternative feedstuffs can be a feasible measure to reduce swine production cost. GuarPro F-71 (GP71), a newly developed guar meal product, is considered as a potential protein source for pigs. This preliminary study was conducted to evaluate the effects of GP71 inclusion in feed on growth performance and nutrient metabolism of growing pigs. Sixty crossbred barrows (31.9±1.84 kg body weight (BW)) were allotted to one of five dietary treatments in a completely randomised experiment design, with four pens/treatment and three pigs/pen. Diet 1 was a maize- and soybean-based basal control diet formulated to meet NRC recommendations. GP71 was used to replace 25, 50, 75, and 100% soybean meal in diet 1 (on an equivalent crude protein (CP) basis) to generate diets 2, 3, 4, and 5, respectively. Crystalline amino acids were used to balance the essential amino acid concentrations across the five diets. Inclusion of GP71 quadratically reduced average daily feed intake (ADFI) (P=0.01) with no observed clinical signs of unhealthiness of pigs. The blood plasma concentrations of six metabolites, including urea nitrogen, total protein, albumin, glucose, total cholesterol and total triglycerides, were not affected (P>0.30), indicating that the pigs’ metabolic utilisation of nutrients was not compromised. The cubic effect (P<0.05) of dietary GP71 inclusion on G:F ratio suggested that the level of soybean meal replacement (up to 75% soybean meal) did not negatively affect feed efficiency in pigs. In short, the feed intake reduction due to the dietary GP71 inclusion was, if not solely, responsible for the average daily gain (ADG) and final BW reduction. This study suggested that using GP71 to replace soybean meal up to 75% (on an equivalent CP basis) can negatively affect ADFI and ADG, but not feed efficiency, in growing pigs. The reasons for the ADFI and ADG reduction need to be understood in future research.
