Fructans are classified as prebiotic, which is defined as nondigestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon, and thus improve host health. In addition to their intestinal health benefits by increasing beneficial microbial populations, fructans have been shown to decrease fecal odor components, reduce blood cholesterol, prevent or inhibit the occurrence of some types of cancer, enhance vitamin synthesis, increase mineral absorption, and stimulate the immune system. Different forms of fructans can have different physiological effects in dogs. Specific effects may vary due to fructan chain length and/or rate of fermentation. The type of diet utilized (plant-based or animal-based and level of crude protein) and variation among individual animals might greatly affect the efficacy of fructans supplementation. The full beneficial effects of fructans probably will not be experienced unless dietary concentrations are above 0.4% of dry food. In this review, the importance and effects of fructans were emphasized and the studies investigating use of fructans in dogs were summarized.

Fruktanlar prebiyotik niteliğinde olan maddelerdir. Prebiyotikler kalın barsakta bir veya sınırlı sayıda bakteri türünün gelişimini ve/veya aktivitesini uyarma yoluyla konağı olumlu yönde etkileyen sindirilemeyen gıda içeriği olarak tanımlanmaktadır. Fruktanların yararlı mikrobiyal popülasyonu arttırma yoluyla barsak sağlığına olan faydalarına ek olarak dışkı koksunu oluşturan bileşikleri azalttığı, kan kolesterol seviyesini düşürdüğü, bazı kanser tiplerinin oluşumunu engellediği, vitamin sentezini arttırdığı, mineral emilimini yükselttiği ve bağışıklık sistemini uyardığı tespit edilmiştir. Fruktanların farklı formları köpeklerde farklı etkilere sahip olabilmektedir. Fruktanların etkileri zincir uzunluğu ve fermantasyon oranı gibi özelliklerden dolayı değişebilmektedir. Kullanılan diyetin tipi (bitkisel veya hayvansal temelli, ham protein seviyesi) ve köpekler arasında bireysel farklılıklar fruktan ilavesinin etkinliğini değiştirebilmektedir. Fruktanların diyetteki konsantrasyonları kuru mamanın % 0.4’ünün üstünde olmadığı zaman yararlı etkileri görülmemektedir. Bu derlemede fruktanların önemi ve etkileri vurgulanmış olup köpeklerde fruktanların kullanımı ile ilgili araştırmalar özetlenmiştir
