Lipid Metabolism Indices and Fatty Acids Profile in the Blood Serum of Broiler Chickens Fed a Diet With Lignocellulose

Abstract

The aim of the research was to determine lipid metabolism indices and fatty acid profile in the blood serum of Ross 308 chickens (n = 48), fed a finisher mixture supplemented with 0, 0.25, 0.5 and 1.0% of lignocellulose. The feeding trial lasted from 21 to 42 d of the birds' age. Blood samples were collected from each chicken at 42d of age from the pterygoid canal vein. In the blood serum the content of triglycerides (TG), total cholesterol (TCHOL) and high density lipoprotein (HDL) fraction was determined by the spectrophotometric method. The fatty acids concentration was estimated with the use of the gas chromatography method. Lignocellulose in doses of 0.5 and 1.0% significantly reduced the concentration of triglycerides and low density lipoprotein (LDL) fraction. Saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) content was not affected by dietary treatments whereas lignocellulose significantly influenced the profile of polyunsaturated fatty acids (PUFA) from n-3 and n-6 families. Insoluble fiber decreased (p<0.05) serum concentration of α-linolenic acid (C18:3n-3) and increased share of docosahexaenoic acid (C22:6n-3), dihomogammalinolenic acid (C20:3n-6) and arachidonic acid (C20:4n-6) in total PUFA, compared to the control birds. The results of the present study have shown that the incorporation of limited amounts of lignocellulose into the broiler diet can influence the lipid metabolism in the chickens.

Effect of Pidotimod, Astragalus and Eachnicea on Immune Response and Growth Performance of Broiler Chicks

“…Concerning the renal function in the current study at 35 days (Table 4) the creatinine and uric acid levels were non-significantly (P<0.05) affected by the addition of Eachnicea, Pidotimod and Astragalus to the broiler drinking water when compared with the control group. This provides evidence for the hepato and reno-protective effects of group supplemented with Eachnicea agreed with Speranda et al [41] who reported that, the dietary Eachnicea supplementation had no effect Oligosccharideds(XOS) [47]. Thus, the reduction of serum triglyceride, cholesterol and LDL in the concurrent study may be attributed to the presence of vitamin E and XOS in its structure.…”

Supplementary outcomes of betaine on economic and productive performance, some biochemical parameters, and lipoprotein lipase gene expression in finishing male broilers

“…Betaine might activate liver lipid mobilization and improve hepatic lipoprotein secretion as indicated by El-Shinnawy [36] which supported the strong positive significant correlation between TG and GLB obtained in G3. The trend of serum cholesterol observed in G3 was partially in agreement with Boguslawska et al [34] who reported that betaine supplementation can lead to higher serum cholesterol. Additionally, Hayes et al [37] indicated that betaine might affect cholesterol partitioning or might enhance the transportation of cholesterol in pigs.…”

“…Blood lipid metabolites including levels of CHL, TG, lipoprotein fractions and fatty acids profile, are sensitive indicators of rate of fat metabolism concentration in chicken [33]. Inconsistance to the present results, Bogusławska et al [34] observed increased plasma TG (18%) of betaine-fed pigs which could affect cholesterol metabolism, furthermore, Martins et al [35] reported significant increase ( P > .05) in blood serum concentrations of triglycerides in response to dietary betaine supplementation in broilers. Betaine might activate liver lipid mobilization and improve hepatic lipoprotein secretion as indicated by El-Shinnawy [36] which supported the strong positive significant correlation between TG and GLB obtained in G3.…”

Effect of Solid-State Fermented Wheat Bran Supplemented with Agrimony Extract on Growth Performance, Fatty Acid Profile, and Meat Quality of Broiler Chickens

“…It has been confirmed that feed fibre (cellulose, oat flakes) has a positive impact on fat metabolism and, subsequently, the level of lipid metabolites in chicken blood serum [48]. The same point was noted in the study of Boguslawska-Tryk et al [49]. They claimed that the addition of nonfermentable fibre to feed (lignocellulose in the amount of 0.5-1%) has an antilipidemic effect.…”
