摘要： Microbiota-targeted therapies for hypercholesterolemia get more and more attention and are recognized as an effective strategy for preventing and treating cardiovascular disease. The experiment was conducted to investigate the cholesterol-lowering mechanism of Lactobacillus delbrueckii in a pig model. Twelve barrows (38.70 ± 5.33 kg) were randomly allocated to two groups and fed corn–soybean meal diets with either 0% (Con) or 0.1% Lactobacillus delbrueckii (Con + LD) for 28 days. L. delbrueckii–fed pigs had lower serum contents of total cholesterol (TC), total bile acids (TBAs), and triglyceride, but higher fecal TC and TBA excretion. L. delbrueckii treatment increased ileal Lactobacillus abundance and bile acid (BA) deconjugation and affected serum and hepatic BA composition. Dietary L. delbrueckii downregulated the gene expression of ileal apical sodium-dependent bile acid transporter (ASBT) and ileal bile acid binding protein (IBABP), and hepatic farnesoid X receptor (FXR), fibroblast growth factor (FGF19), and small heterodimer partner (SHP), but upregulated hepatic high-density lipoprotein receptor (HDLR), low-density lipoprotein receptor (LDLR), sterol regulatory element binding protein-2 (SREBP-2), and cholesterol-7α hydroxylase (CYP7A1) expression. Our results provided in vivo evidence that L. delbrueckii promote ileal BA deconjugation with subsequent fecal TC and TBA extraction by modifying ileal microbiota composition and induce hepatic BA neosynthesis via regulating gut–liver FXR–FGF19 axis. © Copyright © 2020 Hou, Peng, Wei, Li, Yuan, Huang and Yin.

关键词： Prebiotics;Gut microbiota;Intestinal health;Short-chain fatty acids

摘要： The goal of prebiotic applications from different sources is to improve the gut ecosystem where the host and microbiota can benefit from prebiotics. It has already been recognized that prebiotics have potential roles in the gut ecosystem because gut microbiota ferment complex dietary macronutrients and carry out a broad range of functions in the host body, such as the production of nutrients and vitamins, protection against pathogens, and maintenance of immune system balance. The gut ecosystem is very crucial and can be affected by numerous factors consisting of dietary constituents and commensal bacteria. This review focuses on recent scientific evidence, confirming a beneficial effect of prebiotics on animal health, particularly in terms of protection against pathogenic bacteria and increasing the number of beneficial bacteria that may improve epithelial cell barrier functions. It has also been reviewed that modification of the gut ecosystem through the utilization of prebiotics significantly affects the intestinal health of animals. However, the identification and characterization of novel potential prebiotics remain a topical issue and elucidation of the metagenomics relationship between gut microbiota alteration and prebiotic substances is necessary for future prebiotic studies. © 2020 Chinese Association of Animal Science and Veterinary Medicine

关键词： antioxidative;fatty acids;finishing pig;growth performance;ramie

摘要： This study was conducted to evaluate the effects of ramie (Boehmeria nivea, previously known as a fibre crop and also called "China grass") included in diets on growth performance, antioxidative capacity and muscular fatty acid profile of finishing pigs. A total of 180 Xiangcun Black pigs (initial body weight =70.71 +/- 1.21 kg) were randomly allotted to 1 of 5 dietary treatments with six pens of six pigs per pen. The pigs were provided a basal diet or a diet contained 3%, 6%, 9% or 12% of ramie powder during a 50-day experiment period. The results showed that the inclusion of ramie increased (quadratic, p < 0.05) the average daily gain (ADG) and gain:feed ratio (G:F) with the highest value of ADG and G:F in 3% ramie group, but ramie content in the diet up to 9% reduced the growth performance of the pigs compared with that of 3% ramie group. The activity of serum total superoxide dismutase (SOD) was increased (linear, p < 0.05) by ramie, while content of malondialdehyde was decreased (linear, p < 0.05). As increasing the dietary ramie level, the mRNA expression level of SOD1 was increased quadratically (p < 0.05) in muscle tissues. Moreover, the addition of ramie linearly increased (p < 0.05) polyunsaturated fatty acids content, whereas it linearly reduced (p < 0.05) the lipid indices of atherogenicity (AI) and thrombogenicity (TI) in muscle tissues, and lower values of AI and TI reflect a "healthier" fat composition. The results indicated that ramie in a diet not more than 9% may improve antioxidative capacity with no detrimental impact on growth performance of Chinese native finishing pigs; meanwhile, it could beneficially change the pork fatty acid pattern which has a positive impact on consumer's health.

摘要： Early colonization in the gut by probiotics influences the progressive development and maturity of antioxidant and immune system functionality in the future. This study investigated the impact of orally administrated Lactobacillus delbrueckii (LAB) during the suckling phase on future antioxidant and immune responses of the host, using a piglet model. One hundred neonatal piglets received saline (CON) or LAB at the amounts of 1, 2, 3, and 4 mL at 1, 3, 7, and 14 d of age, respectively. The piglets were weaned at the age of 21 d and fed until the age of 49 d. Serum, liver, and intestinal samples were obtained at 21, 28, and 49 d of age. The results showed that LAB tended to decrease serum 8-hydroxy-2-deoxyguanosine concentration and decreased the concentration of serum and hepatic malondialdehyde, but increased the activity of hepatic glutathione peroxidase on days 21, 28, and 49. The concentrations of secretory immunoglobulin A and some inflammatory cytokines and chemokines were increased (P < 0.05) in the intestinal mucosa of LAB-treated piglets on days 21, 28, and 49 compared to that of CON piglets. Likewise, protein expression of cyclooxygenase 2 and inducible nitric oxide synthase in the intestine of LAB-treated piglets was increased (P < 0.05) during the whole period. These results indicate that administration of LAB to the suckling piglet could improve antioxidant capacity and stimulate intestinal immune response, and these long-lasting effects are also observed up to 4 weeks after weaning. A proper utilization of LAB to neonates would be beneficial to human and animal's future health.

关键词： Digestion;Feeding;Genetic mapping;Lysine;Nutrition;Protein

摘要： We hypothesized that balancing the content of exogenous amino acids, especially lysine, to reduce protein content in swine diets could reduce nitrogen (N) pollution associated with animal husbandry. Two experiments (45 d each experiment) were performed on weaned piglets (Duroc × Landrace × Yorkshire, 28 d of age) to test this and to determine the optimal lysine to crude protein (Lys:CP) ratio in diet. In Exp. 1, 12 piglets (6 replicates [n = 6]) were fed diets containing different levels of CP (17% and 20%) but the same level of Lys. Increased CP content resulted in significant increases (P < 0.05) of average daily gain (ADG), average daily feed intake (ADFI), and body weight (BW), but did not affect the feed to gain ratio. In Exp. 2, 24 piglets (8 replicates [n = 8]) were fed 1 of 3 diets as follows: 1) 20% CP with a regular Lys:CP ratio (6.23%, control); 2) 17% CP with a reduced Lys:CP ratio (6.14%, LL); or 3) 17% CP with a standard Lys:CP ratio (7.32%, SL). The ADG, final BW, serum concentrations of growth hormone and insulin-like growth factor-1, villus height in the jejunum, and villus height to crypt depth ratio were the lowest in piglets fed LL diet, whereas blood urea N concentration was the lowest and the value of lipase activity was the highest in the piglets fed SL diet. The SL diet did not affect growth performance, intestinal morphology, or serum hormone concentrations, indicating that reduced dietary N with a high Lys:CP ratio can efficiently reduce dietary N excretion without negatively affecting weaned piglets. © 2019 Chinese Association of Animal Science and Veterinary Medicine

Eighty pigs with an average body weight (BW) of 30 kg were randomly divided into eight groups: A control group, a group that received antibiotic treatment, and six groups fed diets supplemented with 100, 250, and 500 g/t XOS, of which three groups were in the growing period (GP, 30–65 kg BW) and three groups in the growing and fattening period (GFP, 30–100 kg BW). At the end of the experiment, the intestinal contents were sampled for analyses of gut microbiota and bacterial metabolites including short-chain fatty acids (SCFAs) and bioamines. The results showed that 100 g/t XOS supplementation during the GFP significantly reduced the relative abundances of presumably pathogenic bacteria (Proteobacteria and Citrobacter), but enhanced the relative abundances of likely beneficial bacteria (Firmicutes and Lactobacillus). However, XOS supplementation during the GP showed little effect on the gut microbiota when pigs were killed at 100 kg BW. Meanwhile, 100 g/t XOS supplementation during the GFP decreased the level of 1,7-heptane diamine and increased the acetic acid, straight-chain fatty acids, and total SCFAs concentrations in the intestinal contents. Statistical analysis showed that both the dose and exposure time to XOS supplementation affected the microbial communities. In summary, 100 g/t XOS supplementation during the GFP modified the gut microbiota composition and metabolic activity. Possible consequences of such changes for the host are discussed. © 2019, The Author(s).

摘要： 本试验旨在研究低聚木糖(XOS)对生长肥育猪血浆生化参数、肌肉氨基酸含量和肌纤维类型组成的影响。试验选取70日龄、平均体重约为30 kg的杜×长×大三元杂交猪80头,随机分为8组,每组10个重复(公母各占1 /2) ,每个重复1头猪。试验设对照组、抗生素组、30 ~ 65 kg阶段100、250和500 g /t XOS组以及30 ~ 100 kg阶段100、250和500 g /t XOS组。于试猪平均体重达100 kg时,前腔静脉采血,离心分离血浆,测定生化参数;屠宰后取背最长肌样品,测定其氨基酸含量及肌纤维类型和肌肉生长相关基因mRNA表达量。结果表明: 1)与对照组或抗生素组相比,饲粮添加不同剂量XOS可显著提高血浆球蛋白含量(P<0.05) ,显著降低白蛋白/球蛋白值(P<0.05) ; 2)与对照组或抗生素组相比,30 ~ 65 kg阶段饲粮添加250 g /t XOS可显著降低背最长肌中苏氨酸(Thr) 、亮氨酸(Leu) 、苯丙氨酸和丝氨酸(Ser)含量(P<0.05) ,30 ~ 65 kg阶段饲粮添加500 g /t XOS可显著增加背最长肌肌球蛋白重链Ⅱx(MyHCⅡx) 、生肌决定因子(MyoD) 、肌细胞生成素(MyoG)和生肌增强因子2A(MEF2A) mRNA表达量(P<0.05) ; 3)与对照组或抗生素组相比,30 ~ 100 kg阶段饲粮添加100或500 g /t XOS可显著增加背最长肌中Thr、Leu、Ser、总氨基酸、必需氨基酸和鲜味氨基酸含量以及MyHCⅡx、MyoD、MyoG、MEF2A和肌肉生长抑制素mRNA表达量(P<0.05) 。综上所述,饲粮添加一定剂量的XOS可调控机体氮代谢,上调肌纤维类型和肌肉生长相关基因的表达,且以30 ~ 100 kg阶段添加100 g /t XOS的效果较佳。
