Ensuring adequate feed intake in young piglets is crucial for their growth, health, and overall performance. Piglets are weaned at an early age, which exposes them to significant stressors, including separation from the sow and the transition from liquid to solid feed. During this critical period, their immune systems and digestive tracts are still developing, making them more vulnerable to nutritional deficiencies and diseases.
A lack of adequate feed intake during the early post-weaning phase can lead to delayed growth, increased morbidity, and reduced uniformity within litters. Piglets that consume insufficient feed may develop weaker gut integrity, which in turn compromises nutrient absorption and makes them more susceptible to digestive disorders such as post-weaning diarrhoea.
This condition is a major concern for pig producers, as it can negatively impact animal welfare, increase veterinary costs, and reduce overall productivity. Producers employ various strategies to enhance feed intake in piglets. Besides using highly digestible ingredients, supplements such as probiotics, phytogenics, and organic acids have been widely utilised to improve gut health and encourage feeding behaviour. Among these solutions, taste enhancers—particularly those that impart sweetness—have played a key role in stimulating appetite in piglets, making the transition to solid feed smoother and more efficient.
The role of artificial sweeteners in piglet feed
Sweetness is a primary driver of feed intake in piglets, as young animals have a natural preference for sweet flavours. Traditionally, sweeteners such as saccharin have been widely used in piglet diets to enhance palatability and increase voluntary feed intake. Saccharin-based products have been effective in enticing piglets to consume more feed during the post-weaning phase, supporting their early development and reducing performance variability within a group. However, the reliance on saccharin in piglet feed has come under scrutiny due to growing regulatory concerns. Although saccharin has been a common feed additive in the industry, the European regulatory framework has increasingly questioned its use, citing potential health risks and concerns about consumer safety. Regulatory agencies have been evaluating alternative sweeteners and strategies that can achieve similar results without the risks associated with synthetic additives.
Changes in Regulation and the Search for Alternatives
European authorities have been challenging the use of saccharin in animal nutrition for several years. Preliminary discussions began as early as 2021, signalling potential restrictions. In 2024, the European Food Safety Authority (EFSA) issued firm guidelines limiting the use of saccharin in piglet feed, with regulatory deadlines set for 2025. These new regulations have prompted feed manufacturers and producers to search for effective alternatives that can sustain feed intake in piglets without relying on saccharin. While many suppliers have responded by formulating blends of generic palatants, which may result in lower efficiency or higher feed costs, NUQO has taken a more advanced and disruptive approach to addressing this challenge. By leveraging five years of dedicated research, NUQO has developed a unique technology that integrates natural taste enhancers with phytogenics, offering a scientifically backed, highly effective solution for the post-weaning period.
Nuqo’s advanced technology: a game-changer in piglet nutrition
NUQO’s innovative solution is the result of an extensive five-year research project aimed at optimising feed intake and gut health in young piglets. This advanced formulation combines exclusive taste-enhancing compounds with phytogenic ingredients known for their beneficial effects on digestion and immune function. Unlike conventional sweeteners, this technology provides a multi-faceted approach to stimulating appetite and improving post-weaning performance.
The unique formulation is further enhanced through a proprietary micro-agglomeration manufacturing process. This state-of-the-art technology ensures maximum stability and efficacy of the active ingredients, even at low inclusion rates. By creating a structured matrix that protects the active components, NUQO’s micro-agglomeration process guarantees consistent taste delivery and extended palatability, making it a superior alternative to conventional sweeteners.
Scientific validation: Nuqo’s research-backed performance
To validate the efficacy of its technology, NUQO conducted a comprehensive study at the University of Berlin under the supervision of Professor K. Männer. The study involved 200 healthy piglets (Danbred F1 x Duroc) distributed across 20 pens (10 pens per treatment). The piglets, weaned at 25 days of age (±2 days, approximately 7 kg body weight), were fed two different diets over a 42-day feeding period: a negative control (NC) diet and a diet supplemented with NUQO’s innovative technology (NQ).
During the first two weeks post-weaning, piglets in the NQ group exhibited a 10% increase in weight gain compared to those in the NC group, accompanied by a 4% increase in feed consumption. The feed conversion ratio (FCR) was improved by 6%, highlighting the enhanced efficiency of the NUQO technology. Over the full 42-day period, the benefits of NUQO’s technology became even more pronounced. Piglets in the NQ group achieved a 5% higher body weight gain and a 3% increase in feed consumption compared to the NC group. The feed efficiency also improved by 2%, demonstrating the long-term impact of the innovative formulation.Â
In addition to improved performance metrics, NUQO’s technology significantly reduced the incidence of post-weaning diarrhoea. Faecal consistency scores showed a 60% improvement compared to the control group, indicating better intestinal health and overall well-being. Furthermore, piglets receiving the NQ treatment displayed greater uniformity within their groups, with fewer underperforming individuals, leading to more predictable and stable production outcomes.
A future-proof solution for piglet nutrition
NUQO’s technology represents a breakthrough in piglet nutrition, providing a highly effective alternative to saccharin-based sweeteners. By combining exclusive taste enhancers with scientifically selected phytogenic compounds and leveraging advanced micro-agglomeration technology, NUQO ensures that piglets receive a safe, stable, and highly palatable feed solution. With regulatory changes set to take full effect in 2025, NUQO stands at the forefront of innovation, offering a future-proof solution that meets both performance and safety requirements. By anticipating industry needs and investing in rigorous research, NUQO has become a leader in next-generation feed additives, delivering technologies that benefit the entire feed industry.
