Swine production: criteria for efficient swine nutrition

Date: 15/07/2026

Nutrition plays a central role in animal performance, influencing feed intake, weight gain, feed conversion, gut health and nutrient utilization. In swine production, ingredient selection should consider nutritional quality, digestibility and palatability to determine how each raw material contributes to diet efficiency and nutritional balance.

Selecting the right raw materials is essential because pigs’ nutritional requirements vary according to age, genetics, production stage, climate and water availability. As a result, effective feed formulations depend on technical criteria and the selection of ingredients capable of meeting the animals’ nutritional needs throughout each stage of production.

In this article, you will learn:

What influences pigs’ nutritional requirements?

In swine feeding, diet formulation primarily focuses on providing adequate energy and protein. Therefore, ingredients used in swine nutrition must supply essential macronutrients, including carbohydrates, lipids and proteins, according to the animals’ nutritional requirements at each production stage.

Diet composition varies according to several factors, including:

● Age: younger animals require diets with higher protein levels to support growth and development.
● Genetic potential: pigs with greater growth potential require higher-protein diets to sustain performance.
● Climate: temperature fluctuations affect animals’ energy expenditure and may require adjustments to diet formulation.
● Production stage: nutritional requirements vary according to physiological status, requiring specific formulations for piglets, gestating sows, lactating sows and finishing pigs.
● Feed ingredients: because pigs are monogastric animals, they utilize ingredients with high digestibility, lower fiber content and higher energy and protein levels more efficiently.
● Water availability: water influences feed intake, digestion, metabolism and thermoregulation and should be continuously available, potable and easily accessible.

Evaluating these factors makes it possible to formulate diets that better meet the animals’ maintenance, growth and reproductive requirements, contributing to improved efficiency and animal welfare. In addition to macronutrients, vitamins and minerals are also essential components of diet formulation because they participate in important metabolic processes.

Why does ingredient selection impact productive performance?

Ingredient selection directly affects diet efficiency and production outcomes. The main considerations include:

● Piglet taste sensitivity after weaning. During this stage, voluntary feed intake may decline, making ingredient palatability an important factor in stimulating feed consumption.
● Zootechnical performance. Carefully selected ingredients help support performance indicators such as growth, gut health, herd uniformity and productive response throughout the production cycle.
● Weight gain. Diets formulated with high-quality nutritional ingredients promote animal growth and contribute to improved body weight development.
● Feed conversion. Ingredients that are utilized more efficiently by the animal can reduce the amount of feed required to achieve weight gain, improving production efficiency.
● Nutritional efficiency. Formulation should consider not only the presence of nutrients but also the animal’s ability to utilize them effectively for maintenance, growth and reproduction.
● Nutrient utilization. Ingredients with higher digestibility promote the absorption of amino acids, energy, vitamins and minerals, reducing nutrient losses and waste.

Beyond nutritional value, it is important to consider ingredients that provide functional benefits, such as increased feed attractiveness, improved digestibility and enhanced feed efficiency. For this reason, ingredient selection should not be based solely on cost per kilogram, but rather on cost per performance.

Higher-quality ingredients deliver a better return in swine production by supporting productive performance, reducing nutrient losses and improving diet efficiency throughout the production cycle.

Which ingredients have the greatest impact on animal performance?

The ingredients that have the greatest impact on performance in swine production are those that directly supply energy, protein, vitamins and minerals. These nutrients support growth, metabolism, muscle development, immune function and productive efficiency throughout the different stages of pig production.

Energy sources

Energy sources sustain vital functions, support metabolism and promote growth and weight gain in pigs. They also influence productivity, particularly during stages with higher nutritional requirements.

The primary energy ingredients used in swine diets include corn, vegetable oils, animal fats and poultry oil. Selection should consider not only energy content but also raw material quality and the animal’s ability to utilize the nutrient source efficiently.

Protein sources

Protein sources provide amino acids that are essential for muscle development, tissue maintenance and recovery. As a result, they directly influence weight gain and productive performance.

Ingredients such as soybean meal, animal meals and Chicken Protein Hydrolysate may be incorporated into feed formulations according to the production stage and nutritional objectives. High-quality proteins with superior digestibility improve feed conversion and help sustain herd performance.

Vitamins and minerals

Vitamins and minerals support metabolic processes, immune function, bone development and physiological balance. Although required in relatively small amounts, they are indispensable for maintaining animal health, welfare and productivity.

In swine nutrition, minerals such as calcium, phosphorus, sodium, iron, copper, zinc and manganese require careful attention during diet formulation. Deficiencies in these nutrients may impair metabolism, increase susceptibility to disease and reduce animal performance.

Why is ingredient digestibility so important?

Digestibility indicates the extent to which nutrients present in the diet can be effectively absorbed by the pig. This characteristic directly affects several key aspects of swine production, including:

● Nutrient utilization: highly digestible ingredients enhance the absorption of energy, amino acids, vitamins and minerals, increasing the effective utilization of dietary nutrients.
● Feed conversion: when animals utilize feed more efficiently, they generally require less feed to achieve weight gain, improving production efficiency.
● Reduced waste: diets formulated with highly digestible ingredients reduce nutrient losses because a smaller proportion of nutrients remains unavailable to the animal.
● Impact on animal performance: digestibility influences performance indicators such as growth, weight gain, herd uniformity and productive response throughout the production cycle.
● Diet cost: ingredients with superior digestibility can be incorporated more strategically into formulations because they deliver greater nutritional value, even when their cost per kilogram is higher.

This consideration is particularly important for piglets. Following weaning, the transition from a liquid diet to solid feed requires ingredients with high palatability and digestibility that support feed intake, minimize performance fluctuations and facilitate nutritional adaptation during this critical stage.

What are the advantages of Chicken Protein Hydrolysate in swine nutrition?

Chicken Protein Hydrolysate is a protein ingredient produced from poultry-derived raw materials, including meat and edible by-products. In swine production, it is recognized for its high nutritional quality, excellent digestibility and high palatability, making it particularly suitable for high-performance feed formulations. Its main characteristics include:

● Enzymatic hydrolysis: produced through a controlled process that breaks proteins into smaller molecules while preserving their nutritional value.
● Enhanced digestibility: facilitates nutrient absorption and improves nutrient utilization by the animal.
● Free amino acids and peptides: support protein synthesis, rapid absorption and tissue development.
● Palatability: encourages feed intake, particularly during the post-weaning period.
● Application in high-performance diets: recommended for piglets and feed formulations requiring greater nutritional efficiency.

Accordingly, Chicken Protein Hydrolysate should be evaluated not only as a protein source but also for the combination of functional benefits it provides to feed formulations, contributing to improved nutrient utilization, productive performance and feed efficiency.

What should be evaluated when selecting ingredients for swine nutrition?

Ingredient selection for swine nutrition should be based on technical criteria rather than purchase price alone. Digestibility, nutritional quality, palatability, consistency and traceability all help determine whether an ingredient can effectively support performance, formulation reliability and diet efficiency.

The table below summarizes the main specifications that should be evaluated when selecting feed ingredients.
