Tryptophan (Trp) is an essential amino acid that pigs must obtain from their diet. It is involved in protein synthesis and serotonin production, which regulates appetite. It also contributes to the formation of niacin (vitamin B3) and has antioxidant effects, promoting intestinal health and microbiota. In addition, it helps maintain mucosal integrity and regulates the immune system.

In terms of feed presentation, we look for ingredients that provide not only nutrients but also functionality, with the aim of increasing gastric retention time to facilitate protein hydrolysis, greater contact between food and enzymes, and reducing fermentation of undigested protein in the intestine.

Feed presentation is a complex issue, as it can influence both feed mill performance and animal performance. This article analyzes the main factors related to the presentation of pelleted feed that affect productive performance and welfare during the first days after weaning.

How is vitamin quantity expressed? How are vitamin requirements and safety margins estimated in pigs? Can the stability of vitamin activity be compromised?

Vitamins are essential for proper growth and also for ensuring proper function of the nervous system, immune system, reproductive system, bone development, and cell repair. They do not provide energy, and each vitamin performs particular functions that none of the other vitamins can.

Phosphorus is an essential mineral for bone mineralization, energy metabolism, and nucleic acid synthesis. Therefore, strategies to maximize the utilization of phosphorus present in cereals and legumes used in swine nutrition are important, such as the use of phytases. This data sheet describes the structure, types, mechanism of action, and application of phytases.

This data sheet presents a brief compilation of scientific studies that have evaluated the effect of formic acid, lactic acid, and propionic acid on pig gastrointestinal health and production performance at different stages of production.

This first data sheet on organic acids describes their chemical structure, mechanisms of action, and the main benefits of their use in swine nutrition.
