Dietary Fructans and Their Potential Beneficial Influence on Health and Performance Parametrs in Broiler Chickens

Abstract

Fructans, which include inulin and fructooligosaccharides, are non-digestible carbohydrates that are fermented in the large intestine. This review focuses on the effect of these prebiotics on gut microflora, fermentation characteristics, gut morphology, enzymes activity, nutrients digestibility and absorption, lipids metabolism and performance parameters in broiler chickens. Inulin-type fructans can improve performance of birds and health by affecting microbial community in the gastrointestinal tract, gut morphology and nutrient digestion. It is documented that dietary fructans influence the intestinal gut microflora of broiler chickens by increasing the population of Bifidobacterium spp., Lactobacillus spp. and Eubacterium spp. while decreasing the concentration of Clostridium spp. and Escherichia coli in the large intestine and caeca. The supplementation of poultry diets with inulin or oligofructose can lead to an increase of the length of small and large intestines in broilers, elongation of the villus in the chickens jejunal mucosa and increase in the ratio of villus height to crypt depth. The beneficial effect of inulin-type fructans on performance parameters in broilers may be partially explained by the elevated intestinal enzymatic activity under the influence of the fructooligosaccharides and increase of digestibility and absorption of nutrients, mainly protein and fat. The prebiotic effectiveness of inulin-type fructans in broilers depends on a number of factors, like the type of supplement (inulin vs. oligofructose), inclusion level, composition of the basal diet, animal characteristics (age, sex, stage of production) and hygienic conditions (i.e. stress factors).

The effect of chicory root powder on growth performance and some blood parameters of broilers fed wheat-based diets

“…In the present study, feeding broilers with CRP up to 4.5% of diet did not affect BWG and FCR of broilers fed on WW-or GW-based diets. The differences in performance responses of broilers to dietary inulin-type fructans may be attributed to several factors, like type of products and their inclusion levels, composition of the basal diet and experimental hygiene conditions (Boguslawska et al 2012). The lack of significant influence of the CRP on final BWG and FCR at 42 days in the present study could be attributed to the composition of the basal diet and for the environmental conditions of experimentation.…”

Nutraceuticals Induced Structural Changes in Broiler Gastrointestinal Tract Microbiota

“…Data about their immunostimulatory effects conferring beneficial role against infections are ancient and not doubted [27,74,75]. Herbal medicines are receiving widespread attentions especially in developing countries because of their antibacterial behaviour and effect to improve performance and product safety in meat production systems [21,54,61,[76][77][78][79][80]. There are growing number of evidences, that complex, bioactive component rich plant extracts increase digestive enzyme secretion, nutrient absorption and decrease feed-togain ratio in meat-type chickens [28,33,40,51,73,[81][82][83][84][85][86][87][88][89][90].…”

“…Antibiotik merupakan bahan pakan tambahan yang sejak lama dipakai sebagai pemacu pertumbuhan untuk meningkatkan produktivitas ternak. Namun, dampak negatif penggunaan antibiotik dapat menyebabkan resistensi terhadap mikrob terutama bakteri patogen, seperti Escherichia coli, Streptococus, dan Salmonella (Bogusławska-Tryk et al, 2012). Antibiotik juga dapat menyebabkan residu pada produk unggas yang tidak ramah kesehatan bagi konsumen.…”
