Green Tea Powder

Whether or not green tea promotes egg production is unclear. Huainan partridge chickens at 20 weeks of age were divided into two groups, with one group fed a basal diet (control) and one fed a basal diet plus 10 g/kg green tea powder (GTP) for 12 weeks. Egg production (EP) and feed intake (FI) were recorded daily. Plasma lipid parameters, and apolipoprotein-B (Apo-B), 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR), and lipoprotein lipase (LPL) expression were determined every four weeks. Egg production and FI showed no significant difference between the two groups (p > 0.05). Egg weight was 47.58 g in the control group, which was higher than that of the GTP group, and the feed-to-egg ratio (FCR) was 4.62 in the control group, which was lower than that of the GTP group after 12 weeks feeding. Compared with the control group, plasma orexin A (p < 0.05), high-density lipoprotein (HDL), apolipoprotein A (Apo A), and very high-density lipoprotein (VHDL) (p < 0.01, respectively) were increased. Plasma glucose (Glu), free fatty acid (FFA), apolipoprotein B (Apo B), triglyceride (TG), total cholesterol (TC) (p < 0.01, respectively), and low density lipoprotein (LDL) (p < 0.05) were decreased in the GTP group after 8 weeks feeding. The LPL expression in the liver was increased in the GTP group after 8 to 12 weeks feeding when compared to the control group (p < 0.05). Chickens fed GTP did not affect EP, but decreased egg weight, which might be because of lower plasma lipid concentration, increased plasma Orexin A, and liver LPL expression.

The important functions of L-carnitine are fostering the oxidation of long-chain fatty acids by mitochondria and stimulating protein-sparing action by increasing energy derived from lipids. The present study was conducted to investigate dietary effects of L-carnitine on egg production of breeder ostriches. Ninety black neck ostrich breeder birds (60 females and 30 males) were examined randomly (completely randomised design) within three treatments and five replicates for 7 months in breeding season. A basal diet was formulated and used for the control group (L1), while two levels of L-carnitine, 250 mg/kg and 500 mg/kg, were included in the basal diet for treatments L2 and L3, respectively. The egg production percentage, egg weight and defective eggshell percentage were measured. The supplementary diet with 500 mg/kg L-carnitine increased (P < 0.01) the egg production percentage. Means (±s.e.) of egg production percentage for L1, L2 and L3 were 9.68, 12.95 and 17.13% (±1.08), respectively. L-carnitine had no effect on the egg weight and the defective eggshell percentage. The results suggest that basal diet supplemented with 500 mg/kg L-carnitine can increase the egg production percentage of ostriches.

This experiment studied the effect of DPP supplementation in the laying hens’ diet on the ovarian follicle development, hematological variables and hormonal profile of laying hens. Eighty-four, 78-week-old, Lohman LSL hybrids layers were equally divided into four groups (4 groups × 7 replicates × 3 hens); hens in the 1st group were fed a basal diet (control), while those in the 2nd, 3rd and 4th groups, were fed on the same diet and supplemented with 1.25, 2.5 and 5.0 g DPP/kg diet. The results showed that the egg weight, egg mass and laying rate of laying hens treated with DPP levels were significantly increased compared to those of the hens in the control group. Egg weight, egg surface area, albumen quality and percentage of the yolk in treated hens significantly increased compared with controls. The increased DPP levels in laying hens‘ diet significantly (p < 0.05) increased WBC, Hb and TAC, while heterophil/lymphocyte (H/L ratio) significantly decreased. Additionally, the concentrations of FSH and LH and the weights of ovary and oviduct in the treated hens significantly (p < 0.05) increased compared with the control. In conclusion, the DPP supplementation in the hen diet significantly improved egg production, EW, H/L ratio, ovarian follicles, FSH and LH hormones concentrations.

This study was conducted with the objectives to determine the effects of licorice root powder (Glycyrrhriza glabra) on performance, serum parameters, egg yolk cholesterol and antioxidant capacity in laying Japanese quail. Two hundred and forty 10-wk-old Japanese quails were randomly assigned to four dietary groups, each one four times replicated with fifteen quails per dietary groups. Control group fed the basal diet; other groups were fed basal diet supplemented with 0, 0.5, 1.0 and 1.5% licorice root powder. There were no significant differences in terms of final live weight, feed intake, feed conversion ratio, egg weight, serum cholesterol, triglyceride and High-Density Lipoprotein (HDL) concentration between treatment groups. Egg production was higher in control group and 0.5% licorice root powder supplemented groups. 1.0% licorice root powder supplemented group had lower egg production rate. Licorice root powder supplementation decreased Low Density Lipoprotein (LDL) concentration and increased glucose concentration significantly. Licorice root powder supplementation increased total antioxidant status (TAS) and reduced total oxidant status (TOS) and oxidative stress index (OSI). It was concluded from this study that supplementation of licorice root powder at the level of 0.5, 1.0 and 1.5% to the feed of laying quails had no adverse effects on performance. Licorice root powder supplementation can be used to reduce cholesterol level and increase antioxidant status in quails.

Abstract BackgroundIn recent decades, the serum lipid profile of apolipoprotein(a) (Lp(a)) level and apolipoprotein B/apolipoprotein A1 ratio (Apo B/ApoA1) ratio were found more representative for serum lipid level and were recognized as the independent risk factors for various diseases. Although the serum lipid levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) were found associated with symptomatic IDH, no studies have been conducted to date for the evaluation of the association of Apo AI, Apo B, Lp(a) and Apo B/Apo AI levels with symptomatic IDH.MaterialsA total of 1,839 Chinese patients were recruited in the present study. 918 patients were diagnosed as IDH cases and were enrolled in the experimental group. A control group of 921 patients underwent a physical examination during the same period. The serum lipid levels of TC, TG, LDL-C, HDL-C, Lp(a), Apo B and Apo B/Apo AI were examined and analyzed.ResultsThe patients in the control group were collected randomly from patients who were matched with the baseline levels of the aforementioned lipid molecular. The patients with IDH exhibited significantly higher TC, TG, LDL, Apo B and Lp(a) levels compared with the control subjects. The percentage of high-TC, high-TG, high-LDL, high-Apo B and high-Lp(a) were significantly higher in the IDH group. However, hyperlipidaemia was not associated with the degenerated segment of the IDH (P=0.201). The odds ratios (OR) for the incidence of IDH with an elevated LDL-C, TC, TG, Lp(a), Apo B and Apo B/Apo AI were 1.583, 1.74, 1.62, 1.58, 1.49 and 1.39, respectively. The correlation analysis revealed the correlation between elevated LDL-C, TC, TG, Apo B, Lp(a) and incidence of IDH was significant (R2LDL=0.017; R2TC=0.004; R2TG=0.015; R2Apo B=0.004; R2LP(a)=0.021) (P<0.05). ConclusionsThe present study suggests that elevated levels of serum TC, TG, LDL, Apo B, Lp(a) and Apo B/Apo AI are associated with a higher risk for IDH.

Effect of dietary tea polyphenol (TP) on the content of epigallocatechin gallate (EGCG), catechin (C) in egg yolk, and impact on egg quality and production was investigated. For this purpose, 315 healthy Gallus domestiaus aged 42 weeks were selected and randomly divided into 7 groups. The experimental group added 0.02, 0.05, 0.09, 0.14, 0.19 and 0.24% TP to the basic diet. The control group (CK) was fed basal diet. After 10, 20 and 30 days, 15 eggs were randomly selected from each group for egg quality testing, and 20 eggs were selected for EGCG and C content test in the yolk. The results showed that in the 0.24% TP group, the content of EGCG in egg yolk was significantly higher than that of CK group and the 0.02, 0.05, 0.09 and 0.14% TP groups (P < 0.05), and reached the highest on the 30th day (19.171μg/g). The content of C in egg yolk was significantly higher than that in CK group and the 0.02, 0.05, 0.09 and 0.14% TP groups (P < 0.05); and reached the highest on 30th day (7.071 μg/g). The egg weight of the 0.14% TP group on the 10th day and of the 0.19% TP group on the 20th day were significantly lower than that of the CK group (P < 0.05); the egg yolk weight of 0.14% TP on the 10th and 20th days were significantly lower than that of the CK group (P < 0.05). On the 30th day, compared with the control group, the egg weight of the 0.14% TP group was significantly reduced (P < 0.05), the egg yolk color of 0.05 and 0.14% TP groups was significantly increased (P < 0.05). During the whole experiment, the egg production of 0.24% TP group was significantly higher than that of control group (P < 0.05). In conclusion, adding high concentrations of TP can increase the content of EGCG and C in the yolk; however, it has a certain impact on egg weight, yolk color and eggshell thickness. Adding high concentrations of TP may increase egg production. © 2021 Friends Science Publishers

An experiment was conducted for the 56 d period in thirty six adult male albino Wister rats divided equally into four groups. After 7 d adaptation period, all the groups were fed with cholesterol enriched diet for 14 d. Thereafter, one group (T1) was fed on sterile skim milk along with cholesterolemic diet for the next 21 d. The two experimental groups (T2 and T3) received cholesterolemic diet plus spore biomass of B. coagulans B37 and B. pumilus B9, respectively, suspended in sterilized skim milk @ 8-9 log cfu/ ml for the next 21 d. The control group was supplied with clean water along with cholesterolemic diet for 21 d. All the animals were fed on the basal diet along with water during a 14 d post-treatment period. After the adaptation period, the blood samples were collected weekly from the experimental rats up to 42 d, and plasma separated, and subjected to the determination of different plasma lipid fractions. The oral administration of both B. coagulans B37 and B. pumilus B9 resulted a decrease (P Less Than 0.05) in plasma cholesterol, low density lipoprotein (LDL)-cholesterol concentrations and atherogenic index in the experimental rats.

Context The use of antibiotics in poultry production is appropriate; however, it brings a high risk of dissemination of antibiotic-resistant strains of pathogenic and non-pathogenic bacteria and their further transmission to humans via the food chain. Aims The effects of supplementation with Lactobacillus acidophilus (a probiotic) or avilamycin (an in-feed antibiotic growth promoter), on growth performance, digestibility, plasma lipid levels, and the expression of certain growth-related genes were investigated. Methods In total, 135 15-day-old broiler chicks were divided into three groups (n = 45): a control group and two treatment groups. Each treatment group was then further divided into three replicates (15 birds each). The control group was fed a basal diet; the second group received basal diet supplemented with avilamycin (0.1 g/kg); the third group received basal diet plus L. acidophilus (0.1 g/kg). Growth performance (bodyweight, feed intake and feed-conversion ratio) was measured. Digestibility and gene expression were measured at the end of the experiment. Key results Greatest bodyweight gain was achieved in the L. acidophilus-fed chicks, which were significantly (P &lt; 0.05) heavier than the control chicks and the avilamycin-fed chicks. Addition of avilamycin or L. acidophilus to the diet also significantly improved feed efficiency (P &lt; 0.05) compared with the control. Although the digestibility of dry matter, crude protein and crude fibre significantly improved in the two experimental groups compared with the control, ether extract was not affected. In addition, plasma total cholesterol, triglyceride and low-density-lipoprotein cholesterol levels were significantly (P &lt; 0.05) decreased whereas plasma high-density-lipoprotein cholesterol was significantly (P &lt; 0.05) increased in the L. acidophilus group compared with the control. Expression of the genes for growth hormone secretagogue receptor (GHSR), insulin-like growth factor 1 (IGF-1) and insulin-like growth factor 1 receptor (IGF1R) was remarkably upregulated in the skeletal muscles of the two experimental groups. Conclusions Supplementation with L. acidophilus (0.1 g/kg) in the broiler diet had positive effects on growth, feed intake, feed efficiency, digestibility, and plasma lipid levels of the broilers. Implications Lactobacillus acidophilus might be a more useful additive in broiler feed than antibiotic growth promoters such as avilamycin.

Dietary Treatments

Alternative growth promoters are able to not only effectively replace the traditional use of antibiotics but also provide additional health benefits for livestock and reduce food safety concerns. This study investigated the effects of dry Hydrastis canadensis on the laying performance and fecal microbial community of laying hens. Twenty-four Lohmann (LSL, white layer strain) hens were reared from 40 to 48 weeks of age and randomly allotted to four dietary treatments (six birds/treatment). The dietary treatments comprised a basal diet with no treatment as control, a basal diet plus 0.6% powder of dry Hydrastis canadensis roots (R) or leaves (L), and a basal diet plus 0.6% powder of a mixture of dry Hydrastis canadensis roots and leaves (1:1, LR). No mortality was observed in the whole experimental period. The results indicated that albumen height in the LR group was significantly greater than that in the control group. The diet supplemented with Hydrastis canadensis had no significant effects on egg production rate, egg weight, eggshell strength, eggshell thickness, Haugh unit, or yolk height during the whole experimental phase. However, principal coordinate analysis, comparative heat map analysis, and cluster dendrogram analysis of cecal microbiota showed distinct clusters among the groups treated with Hydrastis canadensis and the control group. Regarding blood biochemical parameters, serum cholesterol levels were significantly lower in all Hydrastis canadensis-treated groups compared with those in the control group. Moreover, serum low-density lipoprotein levels were lower in hens supplemented with the leaf of Hydrastis canadensis. The abundances of the phyla Fusobacteria and Kiritimatiellaeota were increased (p < 0.05) in laying hens fed with 0.6% Hydrastis canadensis leaves, whereas the abundance of the phylum Firmicutes in cecum digesta decreased in response to treatment with Hydrastis canadensis roots and leaves. The relative abundance of the Fusobacterium genus was higher in the LR group compared with that in the control. On the contrary, we found a different trend in the Synergistes genus. The potential influences of these microbiota on the performance of laying hens were discussed. The results demonstrate that Hydrastis canadensis can improve the egg albumen height and modulate the cecum digesta microbiota composition of laying hens.

The Impact

We examined the impact of APOE genotype on plasma lipids and glucose in a secondary analysis of data from a five-arm, randomised controlled, parallel dietary intervention trial (‘RISCK’ study), to investigate the impact of replacing saturated fatty acids (SFA) with either monounsaturated fat (MUFA) or carbohydrate of high or low glycaemic index (GI) on CVD risk factors and insulin sensitivity. We tested the impact of APOE genotype (carriage of E2 and E4 alleles versus E3/E3), determined retrospectively, on plasma lipids, lipoproteins and glucose homeostasis at baseline (n = 469), and on the change in these variables after 24 weeks of dietary intervention (n = 389). At baseline, carriers of E2 (n = 70), E4 (n = 125) and E3/E3 (n = 274) expressed marked differences in total plasma cholesterol (TC, p = 0.001), low density lipoprotein cholesterol (LDL-C, p < 0.0001), apolipoprotein B (apo B, p < 0.0001) and total to high density lipoprotein cholesterol ratio (TC:HDL-C, p = 0.002), with plasma concentrations decreasing in the order E4 > E3/E3 > E2. Following intervention, there was evidence of a significant diet x genotype interaction with significantly greater decreases in TC (p = 0.02) and apo B (p = 0.006) among carriers of E4 when SFA was replaced with low GI carbohydrate on a lower fat diet (TC −0.28 mmol/L p = 0.03; apo B −0.1 g/L p = 0.02), and a relative increase in TC (in comparison to E3/E3) when SFA was replaced with MUFA and high GI carbohydrates (TC 0.3 mmol/L, p = 0.03). Among carriers of E2 (compared with E3/E3) there was an increase in triacylglycerol (TAG) when SFA was replaced with MUFA and low GI carbohydrates 0.46 mmol/L p = 0.001). There were no significant interactions between APOE genotype and diet for changes in indices of glucose homeostasis. In conclusion, variations in APOE genotype led to differential effects on the lipid response to the replacement of SFA with MUFA and low GI carbohydrates.

In this study, we evaluated the possible mechanisms through which l-carnitine ameliorates the adverse effects from obesity in rats, induced with a high-fat diet (HFD). For this, 56 albino Wister rats were randomly assigned to 7 groups. The control group was fed a basal diet and injected with saline. The second group was fed the basal diet and injected with l-carnitine (200 mg/kg body mass, by intraperitoneal injection; i.p.). The third group were fed the HFD. The fourth group was fed the HFD and injected with l-carnitine (200 mg/kg body mass, i.p.) for 8 weeks. The fifth group was fed the HFD for 10 weeks. The sixth group were fed the HFD for 10 weeks and were also injected with l-carnitine (200 mg/kg body mass, i.p.) during the final 2 weeks. The seventh group was fed the HFD diet for 8 weeks then the basal diet for 2 weeks. The HFD induced significantly increased levels of hyperglycemia, lipid peroxidation, pathological changes, TNF-α and TGF-β1 protein expression in hepatic tissue, food intake, body weight gain, serum levels of total and non-high-density lipoprotein cholesterol, ketone bodies, triacylglycerol, urea, creatinine, AST, and ALT. However, the HFD diet significantly decreased serum levels of high-density lipoprotein (HDL) and hepatic levels of reduced glutathione. l-Carnitine ameliorated the effects of the HFD on the above-mentioned parameters. This study indicated that l-carnitine had protective and curative effects against HFD-induced hepatosteatosis by reducing hepatic oxidative stress and protein expression of TNF-α and TGF-β1.
