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.

Summary of swine influenza (1/2)

Normally, in pigs influenza is an acute respiratory infection with pyrexia, lethargy, prostration, reluctance to eat and drink. Indoor housed pigs are usually affected simultaneously, with recovery within 1-2 weeks. No adverse effects occur unless there is secondary infection.

Piglet colostrum intake

Colostrum offers 3 essential properties to the piglet: very useful energy source (vital for generating movement and avoiding temperature loss), immune supply (protects against germs that the piglet begins to come into contact with) and natural growth factors (complete the maturity of the piglet).

Why tryptophan is an important amino acid for piglet nutrition

The consequences of the inflammatory and immune responses on tryptophan metabolism could impair the availability of tryptophan for body protein accretion, growth and all other metabolic processes involving this amino acid.

Immunology against PCV2: What difference is there between a subclinically affected animal and an animal with porcine circovirus?

Pigs that are not affected by the disease tend to have a quantity of sero-neutralizing (and also total) antibodies against PCV2, which is significantly greater than those that cause disease
