Effect of Ultra-fine Traditional Chinese Medicine Compounds on Regulation of Lipid Metabolism and Reduction in Egg Cholesterol of Laying Hens

Abstract

This study has the objective of investigating the effects of traditional Chinese medicine prescriptions (TCM) on serum lipid, abdominal and hepatic fat percentage, cholesterol content in eggs, and mRNA expression of genes apoA I and apoB 100. One hundred and thirty five healthy (300-day-old) layers were randomly assigned to three treatments. The hens in control group were fed with the basal diet. The hens in the experimental groups (TCM 1 and TCM 2) were fed with the basal diet supplemented with 1% TCM 1 and 1% TCM 2 respectively over a period of 60 days. Laying performance and the serum parameters relevant to fat metabolism were measured. The results showed that no significant differences were found in average daily feed intake and egg weight among three treatments. Average daily laying rate in TCM treatments was increased, and the cholesterol content in eggs was decreased. The serum triglyceride (TG), total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels in experimental treatments were decreased (p<0.05), while the serum high-density lipoprotein cholesterol (HDL-C) level was increased (p<0.05) compared to the control group. Additionally, abdominal fat percentage decreased in TCM 1 treatment (p<0.05), and hepatic fat percentage decreased in both TCM treatments (p<0.05). The expression of apolipoproteinA I (apoA I) and apolipoproteinB 100 (apoB 100) mRNA in the liver increased in both TCM treatments (p<0.05). These results suggest that the diet supplemented with TCM could increase the expression of apoA I and apoB 100 mRNA in the liver, and decrease lipid content in the serum, and reduce egg cholesterol in layers.

The Effects of Hawthorn (Crataegus oxyacantha) Fruit Extract on Performance, Carcass and Some Serum Parameters of Broilers Reared Under Heat-Stress Conditions[2]

“…In our study, it was determined that the addition of HFE to drinking water had no effect on the growth performance [FI(g), BW G (g) and FCR (g/g)] of broilers raised under heat-stress conditions (Table 2) (P>0.05). W hile our results are in agreement with some literature data, FCR (Li et al, 2009;Sun et al, 2013) and FI and BW G (Li et al, 2009;Marcinèáková et al, 2011;Sun et al, 2013;Song et al, 2018) are not in agreement with some literature data (Zhang et al, 2009;Ahmadipour et al, 2017). The reason for this is thought to be caused by the duration and severity of HS, the extraction method of HFE, the doses added to the diet and the differences in its composition.…”

“…Herbal extracts can regulate serum lipid profili by decreasing lipid oxidation throug h the pheno lic compounds in their content, altering certain biochemical The Effects of Hawthorn (Crataegus oxyacantha) Fruit Extract on Performance, Carcass and Some Serum Parameters of Broilers.... and metabolic processes during the dispersion and deposition of lipids in the tissues (Ye et al, 2 009;Marcinčáková et al, 2011). W hile the results of the study are compatible with several research results (Marcinčáková et al, 2011;Song et al, 2018;Ahmadipour et al, 2019;Dai et al, 2021), they differ from some of the research results (Ye et al, 2009;Xie et al, 2009;Hosseini-Vashan et al, 2016). The reason for the difference in the results of the study is thought to be shaped depending on the trial protocol, HFE type and application dose.…”

“…Hawthorn (Crateagus oxyacantha) fruit extract (HFE) has been reported to have antioxidant, antimicrobial and hypolipidemic properties (Aierken et al, 2017). Although there are studies examining the effects of hawthorn supplementation on poultry (Zhang et al, 2009;Ahmadipour et al, 2017;Song et al, 2018;Dai et al, 2021), no study has been found on the effect on broilers reared under heat stress. The present study evaluates the addition of HFE (Crataegus oxyacantha) to the drinking water of broiler chickens subjected to cyclic heat stress on the performance, carcass characteristics and some serum parameters.…”

Effect of β-Cyclodextrin on Cholesterol Reduction in Egg and Duck Liver Pâté

“…lipid metabolism in duck is very important for not only the customers but also the raisers, because the fat characters of duck are directly linked to people's intakes of TG and cholesterol, flavors of meat and egg, and the cost of feeding. Lipid metabolism in duck mainly locates in liver [20][21][22].…”
