Global pig producers adopt better nutrition and management to improve feed efficiency

Feed conversion efficiency remains a major determinant of profitability in pig production, with nutrition, health, genetics and farm management all playing important roles in achieving favourable feed conversion ratios (FCRs). Poor-quality raw materials, incorrect feed particle size, feeder mismanagement and feed wastage can reduce efficiency. Water quality and adequate flow rates are equally important, as restricted access affects both water and feed intake. Additionally, subclinical respiratory and digestive diseases can divert nutrients away from growth, while diarrhoea reduces nutrient absorption, often resulting in declining performance before visible clinical signs emerge.
‎
‎To identify and address poor FCRs, farmers are advised to adopt a systematic approach that examines feed quality, possible mycotoxin contamination, nutrient specifications and the suitability of diets for different growth stages. They should also assess feeder adjustments, water supply, stocking density, ventilation and temperature stability. Production records provide valuable early warning signs, particularly increasing weight variation among pigs, changes in growth patterns and rising mortality or morbidity. These indicators can help farmers identify underlying problems before they significantly affect productivity.
‎
‎Nutritional balance is equally essential for efficient growth, particularly the supply of amino acids. Lysine is the primary limiting amino acid in pig diets because of its importance in lean tissue development. However, it must be properly balanced with other essential amino acids, including methionine, cysteine, threonine, tryptophan, valine and isoleucine. Appropriate calcium-to-available phosphorus ratios and electrolyte balance also support skeletal development and performance, particularly during heat stress. Furthermore, phase feeding, typically involving three to five well-designed feeding phases, helps match nutrient supply to pigs' changing requirements, reduce wastage and lower feed costs per kilogram of weight gained.
‎
‎Although advances in genetics have improved feed efficiency and lean growth, achieving their full potential depends largely on appropriate nutrition, health and environmental management. Modern commercial pigs have high metabolic demands and are less tolerant of nutritional inconsistencies, overcrowding, heat stress, poor ventilation and inadequate feeder management. Consequently, even minor management deficiencies can result in measurable reductions in growth and feed conversion performance. Aligning digestible amino acid supply with dietary energy and maintaining balanced feeding programmes are therefore essential.
‎
‎Emerging precision livestock technologies are also creating opportunities to improve feed efficiency and overall productivity. Precision feeding systems can adjust nutrient supply according to pigs' growth stages and individual requirements, while automated feed intake monitoring helps detect unusual consumption patterns that may indicate health or management problems. Water monitoring systems also support better control of intake, which is closely linked to feed consumption and metabolic function. Ultimately, sustained improvements in FCR depend on integrating nutrition, genetics, animal health, environmental conditions and effective farm management to maximise productivity and profitability.
