Effect of dietary supplementation of grape seed extract on the growth performance,lipid profile,antioxidant status and immune response of broiler chickens

Grape seed extracts (GSE) contain several beneficial bioactive constituents; therefore, can be utilized as a potential feed additive in broiler chickens. An experiment was conducted to investigate the effect of supplementation of broiler chicken diets with GSE as a natural antioxidant at levels of 125, 250, 500, 1000 and 2000 ppm on the growth performance, serum lipid profile, liver glutathione-reduced, thigh muscle malondialdehyde and humoral immune response against Newcastle disease virus vaccines. This experiment was performed during the life-span of chickens from 0 to 42 days of age. The results of broilers fed on diet supplemented by GSE were compared with those fed on the basal diet (control) or the basal diet supplemented by butylated hydroxytoluene as a synthetic antioxidant (BHT, 125 ppm). No significant differences were observed in the growth performance, percent livability, total lipid, high and very low-density lipoprotein cholesterols when the use of GSE or BHT were compared with the control. Total cholesterol and low-density lipoprotein cholesterol were significantly decreased after intake of GSE compared with BHT in the feed diet. The glutathione-reduced level in liver tissues was significantly increased by inclusion of GSE, but not by BHT. Inclusion of GSE or BHT decreased significantly the malondialdehyde level found in meat tissue. The antibody titer against Newcastle disease virus vaccines was significantly elevated in 28 and 35-day-old broiler chickens fed with a diet supplemented with GSE or BHT, the former providing a higher response. It can be concluded that GSE can be used as an effective natural antioxidant and immunostimulant agent in broiler chicken diets, and that 125 to 250 ppm can be considered as the optimum dosage.

The effects of Lactobacillus-fermented milk on lipid metabolism in hamsters fed on high-cholesterol diet

The objective of this study was to evaluate the effects of local Lactobacillus strains (NTU 101 and 102) on cholesterol-lowering effects in vivo. Thirty male hamsters were housed, divided into five groups, and fed on a cholesterol diet (5 g/kg diet) to induce hypercholesterolemia. Milk fermented by Lactobacillus paracasei subsp. paracasei NTU 101, Lactobacillus plantarum NTU 102, and Lactobacillus acidophilus BCRC 17010 was administrated for this study. After treatment with different fermented milk, blood was taken and liver was removed for the determination of lipoproteins, including total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglyceride. Lactobacilli and bifidobacteria decreased (10⁵) in the control group; when hamsters were fed on fermented milk, the number of lactobacilli (10⁷–10⁸) and bifidobacteria (10⁵–10⁷) was increased. Serum and liver total cholesterol levels were significantly reduced by about 26.4, 23.5, and 30.1% and by about 17.7, 15.9, and 13.4% when hamsters were given fermented milk. However, serum HDL-C and LDL-C were also reduced. The results of this study showed that the hypocholesterolemic effect of local Lactobacillus strains was attributed to its ability to lower serum and liver total cholesterol levels. Thus, local Lactobacillus strains could significantly increase probiotic count.     

Does Dietary vitamin E or C Decrease Egg Yolk Cholesterol?

An experiment was conducted to determine the effect of dietary vitamin E and C on serum metabolites, yolk cholesterol, egg quality, and performance of layer hens. One hundred sixty-eight commercial Hy-Line W-36 layer hens were randomly divided into seven groups and six replicates with four hens in each. Dietary treatments were introduced after the pre-experimental period (10 days) to adjust egg production. Treatments were levels of vitamin E or C (100, 200, and 400 mg/kg diet) supplementation to the basal diet for 4 weeks, whereas the control group received no supplementation. Egg production, egg weight, and feed consumption were recorded during the study. Shell thickness, Haugh unit score, yolk color, yolk weight, yolk cholesterol, and blood parameters were measured at the end of experiment. There was no significant effect of dietary vitamin E or C on hen performance. Egg yolk cholesterol concentrations decreased linearly by antioxidant vitamin supplementation (P?<?0.01). Egg yolk cholesterol reduction did not have any negative effect on egg production rate. Antioxidants, especially vitamin C, increased serum glucose concentration (P?<?0.05). Serum total cholesterol content did not change by vitamin supplementation but cholesterol in high-density lipoprotein (HDL-C) decreased and cholesterol in low-density lipoprotein (LDL-C) increased (P?<?0.05), as dietary vitamin E or C supplementation increased in diets. These results are in conflict with the previous hypothesis that antioxidants have a role in LDL-C removal from the blood or increasing HDL-C. Vitamin E was more effective than vitamin C in this case and if these results are confirmed by further studies, they may result to revision in researchers’ point of view about antioxidant especially in human medicine.

Cholesterol concentration in seminal plasma as a predictive tool for quality semen evaluation

The aim of this study was to investigate the relationship between lipid composition of bovine serum and seminal plasma, seasonality, and semen quality. The experiment was carried out in two groups of Simmental breeding bulls: Group I (ages 2 to 4 yr) and Group II (ages 5 to 10 yr). Blood samples were collected from jugular vein, and bovine semen was sampled with an artificial vagina once per season. Serum concentrations of total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triacylglycerols, nonesterified fatty acids (NEFAs), and lipoprotein electrophoretic patterns were determined. Seminal plasma concentrations of total cholesterol, HDL-C, and LDL-C were assayed. Serum concentration of triacylglycerols in young bulls was significantly higher in winter compared with that in autumn, whereas serum NEFA concentration was significantly higher in autumn compared with that in other seasons. Serum concentration of total cholesterol, LDL-C, and LDL lipoproteins in older bulls was significantly higher in winter than in spring. Seminal plasma concentration of total cholesterol in young bulls was significantly higher in spring compared with that in summer, whereas in older bulls it was significantly higher in winter compared with that in autumn samples. Sperm volume of both groups was significantly higher in summer compared with that in autumn and winter. Sperm motility in young bulls was lowest in summer and differed significantly from the values recorded in other seasons. The changes observed in seminal plasma cholesterol concentration were associated with extracellular lipid use and appeared to be applicable as a biochemical marker of sperm quality.

Physiological study on the influence of some plant oils in rats exposed to a sublethal concentration of diazinon

The present study was aimed to evaluate the influence of olive, sesame and black seed oils on levels of some physiological parameters in male rats exposed to diazinon (DZN). Body weight changes, and levels of serum total protein, albumin, glucose, triglycerides, cholesterol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C), atherogenic index (AI), atherogenic coefficient (AC), cardiac risk ratio (CRR), glutathione (GSH), superoxide dismutase (SOD) and malondialdehyde (MAD) were selected as physiological parameters. The experimental animals were distributed into nine groups. Rats group exposed to DZN and fed with normal diet resulted in pronounced severe changes including reduced body weight gain rate, significantly increase in levels of serum albumin, glucose, cholesterol, LDL-C, AI, AC, CRR and MDA while levels of HDL-C, GSH and SOD were decreased. In rats treated with DZN, the supplementation of the olive, sesame and black seed oils showed remarkable lowering influences of physiological alterations. Moreover, the present results confirmed that these oils possess antioxidative effects against DZN toxicity. Finally, the present findings suggest that these oils are safe and promising agents for the treatment of physiological disturbances induced by DZN and may be also by other pollutants, and toxic and pathogenic factors.

摘要 目的：探讨地中海饮食干预联合有氧运动训练对2型糖尿病（T2DM）患者脂糖代谢水平、肠道菌群及生活质量的影响。方法：选择2021年6月～2022年12月我院110例T2DM患者为研究对象,随机数字表法随机分组,各55例。对照组给予常规健康教育及饮食、运动干预,观察组给予地中海饮食干预及有氧运动训练。比较两组干预前后脂糖代谢指标[空腹血糖（FPG）、餐后2 h血糖（2hPG）、总胆固醇（TC）、甘油三酯（TG）、低密度脂蛋白胆固醇（LDL-C）、高密度脂蛋白胆固醇（HDL-C）]、肠道菌群、生活质量变化及并发症发生率。结果：干预后观察组HDL-C水平高于对照组,FPG、2hPG、TC、TG、LDL-C水平低于对照组（P＜0.05）;干预后观察组大肠埃希菌、肠球菌水平较对照组低,双歧杆菌水平较对照组高（P＜0.05）;干预后观察组治疗、心理精神、生理功能、社会关系评分较对照组高（P＜0.05）;两组并发症发生率差异无统计学意义（P＞0.05）。结论：地中海饮食干预联合有氧运动训练能有效纠正T2DM患者肠道菌群紊乱状态,改善脂糖代谢,减少并发症发生,提高生活质量。
