In conclusion, placental transmission of PCV-2 from a non-immune sow to fetuses is possible when the infection of the dam occurs before gestation or after 62 days of gestation.

The addition of different sources of Se did not affect the immunoglobulin concentrations in the gilt or piglet.

The main objective of this study was to further investigate this issue and determine if vaccination of older pigs would induce an earlier viremia and seroconversion.

The Ig immunocrit method is a simple and useful in assessing the initiation of colostrum and the nursing ability of sows, and the effect of these events on preweaning piglet mortality.

Dietary valine supplementation increases serum albumin, IgM, IgG and prolactin concentrations.

These observations strengthen the hypothesis that selection for high meat production level might be associated with an increased susceptibility of animals to environmental stressors.

Insulin-stimulating diets did not improve prolificity and piglet’s quality.

Chitooligosaccharide supplementation of different molecular weight could be an alternative to antibiotics.

Those piglets supplemented with natural α-tocopherol in drinking water and born from sows supplemented with the same form of vitamin E (SS-SP) had the highest serum α-tocopherol concentration at five days post-weaning.

Supervision of farrowing may allow for improved colostrum intake with benefits to passive immunity.

Live yeast supplementation may improve reproductive performance in sows.

Fenugreek seeds might be interesting as a feed ingredient for young piglets.

β-glucan could improve growth performance and immune function in weaned piglets.

The present study characterized the homologous and heterologous immune response in type-I porcine reproductive and respiratory syndrome virus (PRRSV) infection.

Dietary supplementation of Chinese medicinal herbs may improves intestinal health and nutrient digestibility in weanling pigs.
