Holistic Approach to Enhance Piglet Performance and Gut Health Challenges 

pig

Since the ban in the European Union on pharmaceutical levels of zinc oxide (ZnO) in 2022, the industry has been seeking suitable nutritional solutions to fit its piglet gut health program, aiming to improve piglet health and productivity. Restrictions in the prophylactic use of antibiotics have also opened a new period in the design of post-weaned management and diets.

The main goals of the nursery stage are to avoid post-weaning growth loss and help piglets adapt to a grain-based diet while making this transition as rapidly as possible. The piglet’s immune system matures within the first six or seven weeks of life making simultaneous development, control, and regulation of the immune response a requirement to optimize the immunocompetence in piglets.

At gut level, the development of the mucosal immune system coincides with the colonization of commensal and pathogenic microflora. Studies1 have demonstrated that establishing proper gut microbiota in nursery pigs is paramount for growth performance throughout the whole pig’s production life.

The role of organic acids and trace minerals

Organic acids are one of the most employed ingredients in pig nutrition. The factor that limits an organic acid’s antibacterial efficacy in lower parts of the intestine is the need to be released in the gut2. Protecting organic acids in a fat matrix can support the release in more distal parts of the gastrointestinal tract, inducing a positive modulation of the gut microflora3.

The interest in chelated trace minerals has increased in recent years as they’ve been recognized as more bioavailable than other trace minerals. Chelated trace minerals are shown to improve metabolic functions resulting in enhanced performance responses and less excretion into the environment4.

A study5 conducted by NOVUS found that feeding a protected organic acid blend including benzoic acid (PROVENIA® Feed Solution) and Zn, Cu, and Mn chelates of hydroxy analogue of methionine (MINTREX® Bis-Chelated Trace Minerals) not only improved piglets’ final body weight by +2.2 kg, average daily growth by +13% and decreased the feed-to-gain ratio by 9.5%, but also improved the morphology of the gut mucosa, decreasing the number of E. coli by 16%, while improving beneficial bacteria growth.
