Article Abstract
Background: The objective of this study was to examine the effects of maternal exposure to zearalenone (ZEN) on the intestines of pregnant sows and offspring on postnatal days (PD) 1, 21 and 188. Eighteen pregnant sows (six per treatment) were fed a control diet (ZEN, 0.03 mg kg ), ZEN diet (ZEN, 2.77 mg kg ) and ZEN + 1% modified halloysite nanotube (MHNT) diet (ZEN, 2.76 mg kg ) respectively from gestation days (GD) 35 to 70. At the end of the experiment, three sows of each group on GD70 and the offspring on PD1, PD21 and PD188 were killed to analyze the changes of intestines.
Results: The results showed that ZEN caused oxidative stress, an inflammatory response, changes in the structure of jejunum and alterations of the bacterial numbers in cecal digesta in pregnant sows and PD1 and PD21 piglets. On PD188, bacterial numbers were also altered. MHNTs supplementation reduced the amount of ZEN in the intestine and reversed to a large extent the effects induced by ZEN on the intestines of pregnant sows and offspring.
Conclusion: The results obtained from this study indicated that MHNTs treatment was beneficial for the adsorption of ZEN in the intestine of sows. © 2017 Society of Chemical Industry.

Maternal Supplementation of Dietary Choline and Docosahexaenoic Acid during Gestational Nutrition Restriction Alters Hepatic mRNA and miRNA Expression Patterns in Full-Term Fetal Pigs.

Background: Supplementing choline and docosahexaenoic acid (DHA) to pregnant gilts modified fetal pig hepatic global DNA methylation induced by gestational malnutrition, suggesting that gene expression and regulation and its associated metabolic pathways are affected in the liver of offspring during growth and development.
Objective: To investigate the effect of maternal supplementation of choline, DHA and their interaction on hepatic mRNA expression, miRNA regulation and metabolic pathways in the fetal pigs born to malnourished mothers.
Methods: The abundance of mRNA and miRNA was profiled in fetal liver from sows with undernutrition supplemented with choline and DHA in a 2 × 2 factorial design.
Effect of Low- and High-Sulfur-Containing Amino Acid Inclusion in Diets Fed to Primiparous Sows in Late Gestation on Pre-Partum Nitrogen Retention and Offspring Pre- and Post-Weaning Growth Performance.

Twenty-seven gestating primiparous sows (203 ± 9.1 kg initial body weight on d 89 ± 1 of gestation) were selected to determine the effect of standardized ileal digestible (SID) sulfur-containing amino acid (SAA) intake during late gestation on whole-body nitrogen (N) retention and subsequent litter performance. Primiparous sows were assigned to one of two experimental diets that provided SAAs at 63 or 200% of the estimated requirements during late gestation (0.

Background: Group housing of sows has been extensively studied since the EU banned gestation crating. Well-managed group-housing promotes sow welfare, but the impact varies based on factors such as feeding, group characteristics, and environmental features. Adequate floor space, particularly directly post-mixing, is crucial for social interactions, natural behaviours, and to reduce injuries caused by aggression.

Porcine parvovirus disease is a reproductive disorder caused by the porcine parvovirus (PPV) in sows and is characterised by miscarriage, stillbirth and mummification in pregnant sows. Porcine parvovirus disease poses a significant threat to pork herds and seriously hinders healthy and sustainable development of the pig farming industry. Currently, there is no effective treatment for porcine parvovirus disease except for prevention and control measures.

The aim of this study was to investigate the impact of supplementary feeding with Chinese herbal mixtures on perinatal sows, focusing on their reproductive performance, immunity and breast milk quality. Sixty healthy pregnant sows (Large white, 4 parities) were randomly allocated into five treatment groups ( = 12 per group): the control group received a basal diet, the TRT1 group received a basal diet supplemented with 2 kg/t Bazhen powder (BZP), while the TRT2, TRT3, and TRT4 groups received a basal diet supplemented with 1 kg/t, 2 kg/t, and 3 kg/t Qi-Zhu-Gui-Shao soothing liver and replenishing blood powder (QZGSP), respectively. The trial lasted for a duration of 5 weeks, commencing from day 100 of gestation and concluding on day 21 postpartum.
