Blood metabolic profile of broiler chickens fed diets with different types and levels of inulin

Abstract

SummaryThe study was performed to evaluate the effect of a dietary level of two types of inulin differing in the degree of polymerization (DP), supplemented at different levels, on selected metabolic and immunological parameters of broiler chicken blood. Two hundred and forty 1-day-old broiler chickens were fed a diet without inulin addition (control group, C) or with standard inulin from chicory root with DP ≥ 10 (SI) or long-chain inulin (LCI) of DP ≥ 23 (Inulin Orafti ® GR or Inulin Orafti ® HPX, respectively; Orafti Beneo GmbH, Mannheim, Germany) at a level of 0.2%, 0.4%, or 0.6%. Therefore, 7 dietary treatments were formed. The experiment was carried out for 6 weeks. The addition of inulin had a significant (p ≤ 0.05) impact on the blood parameters analyzed, especially on the protein and lipid profile. The degree of polymerization of inulin and its level in the diet significantly affected the content of glucose and uric acid and creatinine levels in the blood plasma of 21-day-old chickens. The addition of the different types (SI vs. LCI) and levels (0.2, 0.4, and 0.6) of inulin to the diet and the interaction of these factors affected the total protein level and the content of albumins and globulins. Some differences (p ≤ 0.05) were found between the experimental groups in total cholesterol and its HDL fraction content as well as in the activity of ALT and LDH. The other biochemical indices were not affected by the experimental factors. In conclusion, it may be stated that inulin with the higher polymerization degree (LCI; DP ≥ 23) provided better results of the blood metabolic profile throughout the broiler fattening period. However, the impact of this factor is not explicit. The addition of the inulin extract at an amount of 4-6 g per kg of mixture is recommended, but further experiments are recommended.

Intestinal Morphology, Energy Availability, and Growth Performance of Broilers Treated with the Combination of Probiotic and Inulin

“…Dietary inulin has a potency for altering microbial composition in the digestive tract through the inducing the growth of bacteria producing SCFAs (Hoffman et al, 2019). Kowalczuk-Vasilev et al (2017) recommended that the administration of inulin in broiler diets was 4-6 g per kg of mixture (0.4 -0.6%). In this study, the level of inulin addition at 0.5-1.0% in combination with probiotics increased the performance index of the experimental broiler.…”

“…Beneficiary effects of probiotics and prebiotics have potentially improved animal health (Mohammed et al, 2019). Varies factors possibly affect the role of prebiotics in modulating the role of probiotics in improving broiler performance, which were depending on the types and level of oligosaccharides administration (Kowalczuk- Vasilev et al, 2017).…”

Comparative Effects of Using New Multi-Strain Synbiotics on Chicken Growth Performance, Hematology, Serum Biochemistry and Immunity

“…Many authors have studied the effect of administering synbiotics or probiotics on the activity of selected enzymes in blood serum [18,32,37,38,40,42,45].…”

“…The effect of using different synbiotic formulas or probiotics on chicken immunity has also been evaluated by other authors using different hematological tests [1,34,38,39,45,[48][49][50]. Probiotic bacteria as a nutritional component could stimulate the local immune system in the gut; however, their systemic effects would be observable in blood.…”

A Review: Role of Inulin in Animal Nutrition

“…Inulin (4-6 g/kg of diet) with the higher degree of polymerization (DP ≥ 23) provided better results of the blood metabolic profile during the broiler fattening period. Though, the influence of the degree of polymerization is not clear (Kowalczuk-Vasilev et al, 2017).…”
