Oligosaccharides are a class of carbohydrates composed of a small number of monosaccharide units. In recent years, they have gained significant attention in the field of animal nutrition due to their potential to improve animal growth performance. As a leading oligosaccharide supplier, we are deeply involved in researching and providing high - quality oligosaccharides to the animal feed industry. This blog will explore the effects of oligosaccharides on the growth performance of animals.
I. Mechanisms of Oligosaccharides' Action
A. Modulation of Gut Microbiota
One of the primary ways oligosaccharides influence animal growth is by modulating the gut microbiota. Oligosaccharides, such as Mannan Oligosaccharide, act as prebiotics. Prebiotics are non - digestible food ingredients that stimulate the growth and/or activity of beneficial bacteria in the digestive tract.
In the gut, beneficial bacteria like Bifidobacteria and Lactobacilli can utilize oligosaccharides as an energy source. These bacteria then produce short - chain fatty acids (SCFAs) through fermentation, such as acetate, propionate, and butyrate. SCFAs play a crucial role in maintaining gut health. They lower the pH in the gut, creating an unfavorable environment for pathogenic bacteria, such as Escherichia coli and Salmonella. A healthy gut microbiota helps to prevent diseases, which in turn allows animals to allocate more energy towards growth rather than fighting off infections.
B. Enhancement of Nutrient Absorption
Oligosaccharides can also enhance nutrient absorption in animals. The fermentation of oligosaccharides in the gut stimulates the development of the intestinal mucosa. A well - developed intestinal mucosa has a larger surface area, which is beneficial for the absorption of nutrients such as amino acids, vitamins, and minerals.
Moreover, the SCFAs produced from oligosaccharide fermentation can enhance the blood flow to the intestinal epithelium. This increased blood flow facilitates the transport of absorbed nutrients from the gut to the rest of the body, improving the overall efficiency of nutrient utilization.
C. Immune System Stimulation
Another important mechanism is the stimulation of the immune system. Oligosaccharides can interact with immune cells in the gut - associated lymphoid tissue (GALT). They can activate macrophages, lymphocytes, and other immune cells, enhancing the production of cytokines and antibodies.
By strengthening the immune system, animals are better able to resist diseases. For example, in poultry, a diet supplemented with oligosaccharides can reduce the incidence of respiratory and digestive diseases, leading to improved growth rates and feed conversion ratios.
II. Effects on Different Types of Animals
A. Poultry
In the poultry industry, the use of oligosaccharides has shown promising results. Studies have indicated that adding 5% Mixed Feeding Mannan Oligosaccharide to the diet of broilers can improve their body weight gain and feed conversion ratio. The modulation of the gut microbiota by oligosaccharides helps to reduce the colonization of harmful bacteria in the gut, such as Clostridium perfringens, which is associated with necrotic enteritis in poultry.
Laying hens also benefit from oligosaccharide supplementation. Oligosaccharides can improve egg quality, including eggshell strength and yolk color. They also enhance the immune status of the hens, reducing the risk of diseases during the laying period, which is crucial for maintaining high - quality egg production.
B. Swine
In swine production, oligosaccharides are widely used to improve the growth performance of piglets. Piglets have an immature digestive system and are more susceptible to diseases. Oligosaccharides, such as 5% Insoluble Mannan Mixed Feeding Oligosaccharide, can help to establish a healthy gut microbiota in piglets from an early age.


By promoting the growth of beneficial bacteria and inhibiting the growth of pathogens, oligosaccharides reduce the incidence of diarrhea in piglets. This leads to better feed intake, weight gain, and overall growth performance. In growing - finishing pigs, oligosaccharide supplementation can also improve carcass quality by increasing lean meat percentage and reducing fat deposition.
C. Ruminants
For ruminants, oligosaccharides can have a positive impact on rumen fermentation. In the rumen, oligosaccharides are fermented by rumen microbes, which can improve the digestion of fibrous feedstuffs. They can increase the production of SCFAs in the rumen, providing an additional energy source for the ruminants.
Oligosaccharides can also enhance the immune function of ruminants, reducing the risk of mastitis in dairy cows and improving the growth rate of beef cattle. By improving the overall health and growth performance of ruminants, oligosaccharides contribute to more efficient and sustainable ruminant production.
III. Factors Affecting the Efficacy of Oligosaccharides
A. Type of Oligosaccharide
Different types of oligosaccharides have different effects on animal growth. For example, mannan oligosaccharides are more effective in binding to certain pathogens and preventing their adhesion to the gut epithelium. Fructooligosaccharides, on the other hand, are better at promoting the growth of Bifidobacteria. The choice of oligosaccharide depends on the specific needs of the animals and the production goals.
B. Dosage
The dosage of oligosaccharides is also crucial. Too low a dosage may not have a significant effect on animal growth, while too high a dosage can lead to digestive disorders, such as diarrhea. Optimal dosage levels need to be determined based on the type of animal, its age, and the production environment.
C. Animal Species and Age
The response of animals to oligosaccharides varies depending on the species and age. Young animals, such as piglets and chicks, generally have a more significant response to oligosaccharide supplementation because their digestive systems are still developing. Different animal species also have different gut microbiota compositions, which can affect the utilization of oligosaccharides.
IV. Conclusion and Call to Action
In conclusion, oligosaccharides have a wide range of positive effects on the growth performance of animals. They modulate the gut microbiota, enhance nutrient absorption, and stimulate the immune system, leading to improved growth rates, feed conversion ratios, and overall health in poultry, swine, ruminants, and other animals.
