Multiple routes of porcine circovirus type 2 transmission to piglets in the presence of maternal immunity
These findings illustrate the importance of maternal infection, despite robust anti-PCV2 immunity, in early infection of newborn piglets.

Mycoplasma hyopneumoniae infections: clinical signs and diagnosis
Cross-sectional sampling (different age groups during one herd visit) has the advantage that results are obtained quickly.
Dietary Lactobacillus brevis supplement on the performance and immune function of piglets
L. Brevis has intestinal immunomodulatory effects although the low capacity to colonize the porcine gut.
Saccharomyces cerevisiae affects postweaning diarrhea, immune response, and growth performance in weaned piglets
S. cerevisiae should be considered as a successful alternative for the prevention and treatment of diarrhoea in piglets caused by ETEC.
Global gene expression profiling of myeloid immune cell subsets in response to in vitro challenge with PCV2b
PCV2b challenge increases the expression of a large number of immune-related and pro-apoptotic genes mainly in MoDC, which possibly explain the increased inflammation.
Effect of immunological stress to neuroendocrine and gene expression in different swine breeds
This study concluded that Laiwu had stronger capacity of immunological stress resistance and next was Lulai among three breeds. Chromium yeast helped piglets relieve immunological stress.
Dietary lysine content and sanitation conditions on performance of weaned pigs fed antibiotic-free diets
Lysine requirements for piglets fed antibiotic free-diets is higher than NRC (1998) recommendation.
Humoral response and colostral antibody transfer following 'one-dose' pre-mating vaccination of sows against porcine circovirus type-2
One-dose vaccination of sows against PCV2 induces colostral antibody transfer.
Mycoplasma hyopneumoniae: Dynamics of Immunity and Physiology
The interaction between M. hyopneumoniae and its host make M. hyopneumoniae one of the most important contributors to porcine respiratory disease.
Placental transmission of porcine circovirus type 2
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.
Effects of inorganic or organic selenium on immunoglobulins in swine
The addition of different sources of Se did not affect the immunoglobulin concentrations in the gilt or piglet.
Impact of PRRS vaccination timing in pigs with different maternal immunity levels
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.
A simple novel measure of passive transfer of maternal immunoglobulin is predictive of preweaning mortality in piglets
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.
Valine supplementation improves immune and endocrine function of lactating sows
Dietary valine supplementation increases serum albumin, IgM, IgG and prolactin concentrations.
Health and immune traits of Basque and Large White pigs housed in a conventional or enriched environment
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 during the weaning-to-estrus interval in high-prolific multiparous sows
Insulin-stimulating diets did not improve prolificity and piglet’s quality.
