The range of raw materials that are available for use in swine diets is growing. This gives nutritionists more flexibility in formulating cost-effective and precise diets. But we have to be aware of fibre-rich ingredients, as they may come with a high level of anti-nutritional factors.
The use of alternative ingredients and by-products is common in pig diets around the world and is a great way to formulate cost-effective diets or contribute to the profitability and sustainability of the farm. However, these ingredients are often linked with a variable nutrient composition and fibre richness. Some types of anti-nutritional components found in fibre-rich ingredients and by-products can downgrade the potential of the carefully formulated feed.
