Immune response and blood chemistry of pigs fed conjugated linoleic acid

Feeding conjugated linoleic acid up to 1.0% to growing-finishing pigs does not significantly alter either immune system (innate or cell-mediated) or blood chemistry variables.

Abstract

Optimal combinations of acute phase proteins for detecting infectious disease in pigs

Combinations of APPs allowed the detection of disease more sensitively than any individual APP and the best three-protein combinations were CRP, apoA1, pigMAP and CRP, apoA1, Hp, respectively, closely followed by the two-protein combinations CRP, pigMAP and apoA1, pigMAP, respectively.

Maternally derived antibodies at the time of porcine circovirus type 2 vaccination: does it matter?

One issue is to overcome maternal immunity, which is true for all PCV2 vaccines in the market, and another is whether the most from these vaccines is achieved independently of the PCV2 antibody titre at vaccination

Abstract

Porcine reproductive and respiratory syndrome virus-induced immunosuppression exacerbates the inflammatory response to porcine respiratory coronavirus in pigs

We performed a comprehensive analysis of innate and adaptive immune responses in dual-virus infected pigs to understand whether a pre-existing immunomodulatory respiratory viral infection affects the overall immunity to a subsequent porcine respiratory coronavirus (PRCV) infection in pigs.

Abstract

Effects of space allocation on growth performance and immune system in weaning pigs

Stress caused by reduced space allocation may disrupt the cellular immune system in piglets and stimulate the releases of cortisol.

Effects of fermented garlic powder on growth performance and blood profiles of weanling pigs

The use of fermented garlic powder in weanling diet may improve piglet weight gain.

Viability of Lactobacillus plantarum in different protective agents and its effects on growth performance and immunity of weaned pigs

The use of Lactobacillus plantarum as a probiotic, may improve growth performance and immunity in piglets.

Abstract

Dynamics and longevity of maternally-acquired antibodies to Taenia solium in piglets born to naturally infected sows

The observed variations in the level of maternally-acquired Abs amongst piglets will pose a major challenge to the implementation of vaccination programmes against T. solium cysticercosis.

Administration of Pediococcus acidilactici or Saccharomyces cerevisiae boulardii modulates development of porcine mucosal immunity and reduces intestinal bacterial translocation after Escherichia coli challenge

Porcine mucosal immune response against E coli may be modulated by dietary probiotic supplementation.

Effects of phenyllactic acid on growth performance, nutrient digestibility, microbial shedding, and blood profile in pigs

Phenyllactic acid may play as a natural alternative to antibiotics in pig diets.

Evaluation of the effect of increasing dietary vitamin E in combination with different fat sources on performance, humoral immune responses and antioxidant status of weaned pigs

Immune response or triglyceride and cholesterol levels in plasma are influenced by the fat source fed rather than the level of vitamin E in weanling pig.

Abstract

Evidence of cell-mediated immune response and specific local mucosal immunoglobulin (Ig) A production against Lawsonia intracellularis in experimentally infected swine

The purpose of this study was to detect cell-mediated and local humoral immune responses to Lawsonia intracellularis in pigs inoculated with a pure culture of the pathogenic isolate or with an intestinal mucosa homogenate.

Abstract

Environmentally-acquired bacteria influence microbial diversity and natural innate immune responses at gut surfaces

The extent to which early-life environment impacts on microbial diversity of the adult gut and subsequent immune processes has not been comprehensively investigated thus far. We addressed this important question using the pig as a model to evaluate the impact of early-life environment on microbe/host gut interactions during development.

Tryptophan in swine nutrition

Tryptophan has positive effects on voluntary feed intake. This greater feed intake leads to increased growth performance and improved feed conversion ratio in piglets, and to lower body weight losses in sows during lactation.
