Iron complexation of polysaccharides has gained attention in glycobiology research. This study investigated the effects of maternal supplementation with tapioca polysaccharide iron (TpFe) on reproductive performance, colostrum composition, cord blood active components, and growth performance of nursing piglets. The results demonstrated that TpFe supplementation improved feed intake, reproductive performance, colostrum composition, antioxidant and immunological performance, and growth performance in piglets. The findings highlight the potential benefits of TpFe as a natural compound for enhancing piglet production performance.
Simple Summary Nowadays, iron complexation of polysaccharides has recently become a popular topic in glycobiology research. A macromolecular polysaccharide known as polysaccharide-iron complex can affect blood pressure, blood sugar levels, immunity, blood circulation, and has the potential to improve and regulate active substances that exist in animal blood. In this study, an organic iron complex generated from tapioca starch and ferric chloride was utilized. This product is a self-developed, plant-derived, natural compound that has a wide variety of sources and is cost-effective. The results of this study demonstrate that maternal supplementary tapioca polysaccharide iron can improve their feed intake and reproductive performance, adjust the nutritional composition of colostrum, enhance the antioxidant and immunological performance of piglets, and stimulate hormone release in blood, leading to enhanced piglet production performance. Furthermore, this study reveals the correlation between the components of colostrum, cord blood, and piglet performance when sows are fed supplements with tapioca polysaccharide iron. The purpose of this study was to investigate the effect of maternal supplementation with TpFe (tapioca polysaccharide iron) on reproductive performance, colostrum composition, cord blood active components of sows, and growth performance of their nursing piglets. Sixty healthy Duroc x Landrace x Yorkshire sows were randomly assigned to three groups at day 85 of gestation. The experimental diets included a basal diet supplemented with 100 mg/kg FeSO4 & BULL;H2O (CON group), the basal diet supplemented with 50 mg/kg TpFe (TpFe50 group), and the basal diet supplemented with 100 mg/kg TpFe (TpFe100 group), as calculated by Fe content. The experiment lasted from day 85 of gestation to the end of weaning (day 21 of lactation). Results showed that maternal supplementation with 100 mg/kg TpFe improved (p < 0.05) feed intake during lactation, live births, and birth weight of the litter (alive) and increased (p < 0.05) colostrum IgM (immunoglobulin m), IgA (immunoglobulin A), as well as the IgG levels, while it decreased (p < 0.05) the urea nitrogen and somatic cell count of sows. Moreover, sows in the TpFe100 group had higher (p < 0.05) serum iron levels and IgG. Additionally, maternal supplementation with 100 mg/kg TpFe increased (p < 0.05) iron level, total antioxidant capacity (T-AOC), glutathione peroxidase (GSH-px), catalase (CAT), IgG, red blood cells (RBC), and hemoglobin (Hb) of cord blood, similar with the iron content, T-AOC, GSH-px, IgG, RBC, Hb, hematocrit (HCT), and mean corpuscular volume (MCV) of weaned piglet blood. The diarrhea and mortality rates among the nursing piglets were decreased (p < 0.05), while the average weight at day 21 of age was increased (p < 0.05) in the TpFe100 group. Serum PRL (prolactin) levels of sows exhibited a positive correlation (p < 0.05) with live births. Suckling piglet diarrhea was positively correlated with colostrum urea nitrogen level but negatively correlated with colostrum IgM, IgG, and cord blood Hb content (p < 0.05). The mortality of suckling piglets was negatively correlated with serum iron content and IgM in colostrum, GSH-px, and IgG in cord serum of sows (p < 0.05). The average weight of weaning piglets was positively (p < 0.05) related to colostrum IgM and IgG levels, as well as cord serum RBC counts of sows on day 21. In conclusion, maternal supplementation with TpFe can improve the active components of colostrum and umbilical cord blood and improve the growth performance of suckling piglets.
