High-concentrate diet feeding causes oxidative stress, alters rumen fermentation, and impairs the immune functions of lambs during fattening. Selenium (Se) is a trace element that plays a crucial role in alleviating oxidative stress. This study aimed to investigate the effects of dietary Se supplementation on growth performance, antioxidant capacity, and slaughter parameters in fattening lambs. Twenty-four 3-month-old Dorper-Hu hybrid lambs were randomly divided into two groups: a control group (CON) fed a basic diet, and a treatment group (TRT) supplemented with 0.5 mg/kg dry matter (DM) Se for 105 days. The study revealed no significant differences between the CON and TRT groups in terms of growth performance and carcass characteristics (P > 0.05). However, the TRT group tended to have an elevated serum malondialdehyde (MDA) levels (0.05 < P < 0.1) and significantly lower serum cortisol levels (P < 0.05). Furthermore, muscle Se concentrations, superoxide dismutase (SOD), and glutathione peroxidase (GSH-PX) were higher in the TRT group (P < 0.05), indicating reduced oxidative stress and improved stress resistance. Ruminal fermentation parameters improved in the TRT group, with increased pH, propionate, and valerate concentrations, and reduced NH3-N levels (P < 0.05). Meat quality also benefited from Se supplementation, as evidenced by increased redness (a*24 h) and reduced shear force (P < 0.05). Additionally, Se supplementation led to higher liver IgA concentrations (P < 0.05). In conclusion, 0.5 mg/kg Se supplementation alleviates oxidative stress, modulates immune responses, and enhances lamb meat quality.
高精料饲粮饲喂可引起育肥羔羊氧化应激,改变瘤胃发酵,损害其免疫功能。硒(Se)是一种在缓解氧化应激中起重要作用的微量元素。本试验旨在研究饲粮添加硒对育肥羔羊生长性能、抗氧化能力和屠宰参数的影响。选取24只3月龄杜珀-胡杂交羔羊,随机分为2组:对照组饲喂基础饲粮,试验组添加0.5 mg/kg干物质硒,试验期105 d。研究显示,CON组和TRT组在生长性能和胴体特性方面无显著差异(P >; 0.05)。然而,TRT组倾向于血清丙二醛(MDA)水平升高(0.05 < P <; 0.1),血清皮质醇水平显著降低(P <; 0.05)。此外,TRT组肌肉硒浓度、超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GSH-PX)升高(P <; 0.05),表明氧化应激减轻,抗逆性提高。TRT组瘤胃发酵参数改善,pH、丙酸和戊酸浓度升高,NH3-N水平降低(P <; 0.05)。添加硒也有利于肉品质的改善,红度增加(a*24 h),剪切力降低(P <; 0.05)。此外,硒添加导致肝脏IgA浓度升高(P <; 0.05)。由此可见,饲粮中添加0.5 mg/kg硒可缓解氧化应激,调节机体免疫反应,提高羔羊肉质。

<div><div>Present study compared the effect of novel multistrain probiotics on <em>in vitro</em> microbial populations, hydrolytic enzymes, digestibility, fermentation parameters, and antioxidant capacity of the Shal breed sheep. The probiotics were multistrain Bacilli (<em>B. licheniformis</em>, <em>B. subtilis</em> and <em>B. coagulans</em>; 5 × 10<sup>9</sup>, 5 × 10<sup>9</sup>, and 2 × 10<sup>11</sup> CFU/g, respectively), Lactobacilli (<em>Enterococcus faecium</em>, <em>L. rhamnosus</em> and <em>L. plantarum</em>; 2 × 10<sup>10</sup>, 2 × 10<sup>10</sup>, and 2 × 10<sup>9</sup> CFU/g, respectively), yeast (<em>Saccharomyces boulardii</em>; 2 × 10<sup>10</sup> CFU/g), and mixed bacteria-yeast (3:1 ratio) formulations. The treatments included diet without probiotic (control) and diets containing Bacilli (BAC), Lactobacilli (LAC), yeast (YE), mixed Bacilli-yeast (BAC-YE), or mixed Lactobacilli-yeast (LAC-YE), added at 0.1 % of diet DM. Diets were evaluated using 24 and 72-h <em>in vitro</em> gas production techniques. In both incubation times, cellulolytic and proteolytic bacteria counts, microcrystalline cellulase (avicelase), filter paper-degrading (FPD) activity, and protease in BAC, YE, BAC-YE, and LAC-YE groups were higher than the control (P < 0.05), but no significant difference was observed between LAC and the control. At 24 h incubation, LAC exhibited higher (P < 0.05) amylase activity than the free-antibiotic diet. Compared to the control, adding different probiotics to the diet decreased (P < 0.05) protozoa numbers at 24 h. <em>In vitro</em> gas production, organic matter disappearance, metabolizable energy, and truly-degraded substrate were higher in treatments containing different probiotics in comparison to the control (P < 0.05). The use of various probiotic additives reduced the production of methane (P < 0.05), but did not affect antioxidant capacity. At 24-h incubation, ammonia-N concentrations increased significantly in BAC, YE, and BAC-YE compared to the control (P < 0.05), while LAC and LAC-YE showed a non-significant increasing trend. After 72-h incubation, ammonia-N concentrations did not differ significantly among treatments. Different probiotic sources increased total volatile fatty acid production while reducing butyrate proportion during both incubation periods (P < 0.05). Moreover, BAC, YE, BAC-YE, and LAC-YE caused an increase in the molar proportion of acetate, while LAC decreased acetate and increased propionate proportion (P < 0.05). In general, dietary inclusion of the novel multistrain Bacilli and Lactobacilli at 0.1 % of diet DM improved <em>in vitro</em> ruminal microbial populations and hydrolytic enzymes while reducing methane production, thereby enhancing diet efficiency and environmental benefits. The effectiveness of <em>S. boulardii</em> was enhanced when combined with Bacilli or Lactobacilli probiotics, recommending their concurrent use over yeast supplementation alone.</div></
本研究比较了新型多菌种益生菌对沙尔羊体外微生物种群、水解酶、消化率、发酵参数和抗氧化能力的影响。益生菌为多株芽孢杆菌(地衣芽孢杆菌、枯草芽孢杆菌和凝固芽孢杆菌;分别为5 × 109、5 × 109和2 × 1011 CFU/g)、乳酸菌(屎肠球菌、鼠李糖乳杆菌和植物乳杆菌;分别为2 × 1010、2 × 1010和2 × 109 CFU/g)、酵母(博拉迪酵母菌;2 × 1010 CFU/g)和菌酵母混合(3:1比例)配方。对照组为不含益生菌的饲粮,对照组为含芽孢杆菌(BAC)、乳酸菌(LAC)、酵母菌(YE)、混合芽孢杆菌-酵母菌(BAC-YE)或混合乳杆菌-酵母菌(LAC-YE)的饲粮,添加量为饲粮DM的0.1% %。采用24和72 h体外产气技术对饲粮进行评价。在两个培养时间内,BAC组、YE组、BAC-YE组和LAC-YE组的纤维素水解菌和蛋白水解菌数量、微晶纤维素酶(avicelase)、滤纸降解(FPD)活性和蛋白酶均高于对照组(P <; 0.05),但LAC组与对照组之间无显著差异。在孵育24 h时,LAC的淀粉酶活性高于无抗生素日粮(P <; 0.05)。与对照组相比,饲粮中添加不同益生菌可降低24 h时的原虫数量(P <; 0.05)。不同益生菌处理的体外产气量、有机物消失量、代谢能和真降解底物均高于对照组(P <; 0.05)。各种益生菌添加剂的使用降低了甲烷的产量(P <; 0.05),但不影响抗氧化能力。孵育24 h时,BAC、YE和BAC-YE中氨氮浓度较对照组显著升高(P <; 0.05),LAC和LAC-YE中氨氮浓度升高趋势不显著。孵育72 h后,不同处理间氨氮浓度差异不显著。不同的益生菌来源增加了总挥发性脂肪酸产量,降低了丁酸盐比例(P <; 0.05)。BAC、YE、BAC-YE和LAC-YE使乙酸的摩尔比升高,而LAC使乙酸降低,丙酸比例升高(P <; 0.05)。总体而言,在饲粮中添加0.1% %的新型多菌株芽孢杆菌和乳酸菌可改善体外瘤胃微生物数量和水解酶,同时降低甲烷产量,从而提高饲粮效率和环境效益。当与芽孢杆菌或乳酸杆菌益生菌联合使用时,博氏沙门氏菌的效果得到增强,建议它们同时使用,而不是单独补充酵母。

The present study investigated the effects of dietary lipid and lysophospholipid (LPL) levels on growth performance and lipid metabolism in hybrid grouper (Epinephelus fuscoguttatus♀ × E. lanceolatus♂). A 2-factorial design was employed, with three levels of dietary lipid (8 %, 10 %, and 12 %) and three levels of LPL (0 %, 0.1 %, and 0.2 %), yielding nine isonitrogenous, non-isoenergetic experimental diets. The dietary treatments were designated as L8E0, L10E0, L12E0, L8E0.1, L10E0.1, L12E0.1, L8E0.2, L10E0.2, and L12E0.2. Juvenile fish (initial body weight 13.91 ± 0.01 g) were stocked at 30 fish per 500 L fiberglass tank (salinity maintained at 26–30 ‰), with three replicates tanks per treatment. After a 10-week feeding trial, the interaction between dietary lipid and LPL did not significantly affect growth performance or survival rate, but it significantly influenced feed efficiency. However, fish fed diets with 8 % lipid showed higher growth performance than those fed diets with 12 % lipid. Fish fed diets with 0.1 % LPL had significantly higher muscle crude protein content and lower crude lipid content than those fed diets with 0 % or 0.2 % LPL. Additionally, the hepatic lipid droplet abundance was lower in fish fed diets with 0.1 % or 0.2 % LPL than in those fed diets with 0 % LPL. Specifically, fish fed the L10E0.1 diet exhibited the lowest hepatosomatic and visceral indices and the fewest hepatic lipid droplets, together with the highest muscle crude protein content. Furthermore, dietary supplementation with 0.1 % LPL significantly downregulated the relative expression of hepatic lipogenic genes (fas, acc) and upregulated that of hepatic lipolytic genes (lpl, atgl, hsl). In conclusion, the L10E0.1 dietary treatment appears to be optimal for hybrid grouper, synergistically enhancing growth performance, feed efficiency, lipid homeostasis, and muscle nutritional quality.
本试验研究了饲料脂质和溶血磷脂(LPL)水平对杂交石斑鱼(Epinephelus fuscoguttatus♀× E. lanceolatus♂)生长性能和脂质代谢的影响。采用2因子设计,采用3种水平的饲料脂质(8 %、10 %和12 %)和3种水平的LPL(0 %、0.1 %和0.2 %),产生9种等氮、非等能试验饲料。饲粮处理分别为L8E0、L10E0、L12E0、L8E0.1、L10E0.1、L12E0.1、L8E0.2、L10E0.2和L12E0.2。幼鱼(初始体重13.91 ± 0.01 g)以500 L玻璃纤维池30尾(盐度维持在26-30 ‰)的方式放养,每个处理3个重复池。饲喂10周后,饲粮脂质与LPL的互作对生长性能和成活率无显著影响,但显著影响饲料效率。然而,饲料中脂肪含量为8 %的鱼的生长性能高于饲料中脂肪含量为12 %的鱼。饲料中LPL含量为0.1 %的鱼肌肉粗蛋白质含量显著高于饲料中LPL含量为0 %和0.2 %的鱼,粗脂肪含量显著低于饲料中LPL含量为0 %和0.2 %的鱼。此外,饲料中LPL含量为0.1 %或0.2 %的鱼的肝脏脂滴丰度低于饲料中LPL含量为0 %的鱼。其中,L10E0.1饲料的肝体指数和内脏指数最低,肝脂滴最少,肌肉粗蛋白质含量最高。此外,饲粮中添加0.1% % LPL显著下调了肝脏脂肪生成基因(fas、acc)的相对表达,上调了肝脏脂肪分解基因(LPL、atgl、hsl)的相对表达。综上所述,杂交石斑鱼饲粮中添加L10E0.1处理效果最佳,可协同提高生长性能、饲料效率、脂质稳态和肌肉营养品质。

The role of phytochemicals such as polyphenols, essential oils, saponins and organosulfur compounds in ruminant production systems has evolved from their riddance as anti-nutritional factors in the past to current exploration as potential natural antimethanogens, anthelmintics, stress alleviators, growth enhancers, and biopreservatives. This shift stems from the desire to improve animal health, production and product quality while reducing greenhouse gas emissions and reliance on antibiotics and synthetic additives. The impact, mechanism of action and transfer efficiency of dietary phytochemicals for ruminant production and product preservation have, however, been reported to be uncertain primarily due to a lack of optimized application conditions. The current review provides a comprehensive update on the impacts of dietary phytochemicals for ruminant production and product quality enhancement and suggests directions for future research, innovation and adoption. A Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) approach was conducted in Scopus, Web of Science and Google Scholar databases to identify and select peer-reviewed journal articles published between 2010 and 2025. The comprehensive systematic review used data from 174 in vivo studies. The results show no impact, insufficient investigation into the mechanisms and transfer efficiency of dietary phytochemicals for ruminant production and product quality. Nonetheless, there are indications that essential oils and polyphenols hold potential to enhance ruminant production, oxidative stability and health value of edible products. A portfolio of future directions, including optimizing application conditions, customizing diet formulations, educating value-chain actors, enacting harmonized regulations and polices, fostering transdisciplinary collaboration and establishing institutions to coordinate research and innovation, was proposed to fully unlock the value of dietary essential oils and polyphenols in ruminant production systems.
植物化学物质如多酚、精油、皂苷和有机硫化合物在反刍动物生产系统中的作用已经从过去作为抗营养因子的消除发展到现在作为潜在的天然抗甲烷剂、驱虫药、应激缓解剂、生长促进剂和生物防腐剂的探索。这种转变源于改善动物健康、生产和产品质量的愿望,同时减少温室气体排放和对抗生素和合成添加剂的依赖。然而,由于缺乏优化的应用条件,饲粮植物化学物质对反刍动物生产和产品保存的影响、作用机制和转移效率尚不确定。本综述全面介绍了膳食植物化学物质对反刍动物生产和产品质量提高的影响,并提出了未来研究、创新和采用的方向。在Scopus、Web of Science和b谷歌Scholar数据库中,采用系统评价和荟萃分析的首选报告项目(PRISMA)方法来识别和选择2010年至2025年间发表的同行评议期刊文章。这项综合系统评价使用了174项体内研究的数据。结果表明,饲粮中植物化学物质对反刍动物生产和产品质量没有影响,对其机制和传递效率的研究不足。然而,有迹象表明,精油和多酚具有提高反刍动物产量、氧化稳定性和食用产品健康价值的潜力。提出了优化应用条件、定制饮食配方、教育价值链参与者、制定统一的法规和政策、促进跨学科合作以及建立协调研究和创新的机构等一系列未来方向,以充分释放反刍动物生产系统中膳食精油和多酚的价值。

The yellow mealworm (Tenebrio molitor) has gained attention as a sustainable alternative in aquafeed formulation due to its favourable nutritional composition and reduced environmental footprint. Nevertheless, high production cost remains a key constraint. This study investigated the use of mushroom spent substrate (SMS), an agro-industrial byproduct, as a partial replacement for conventional mealworm larvae rearing substrates, with the goal to increase the sustainability and reduce the production cost of mealworm meal (MM), when used as fishmeal and vegetable oil replacer in aquafeeds for juvenile rainbow trout (Oncorhynchus mykiss). Five experimental diets were formulated for juvenile rainbow trout to be iso-proteic (45 %) and iso-lipidic (22 %). A control diet (CTRL) was designed to reflect a standard commercial formulation. Four additional diets, formulated based on the CTRL diet, included 12.5 or 25 % of mealworm meal (replacing 50 and 100 % of the fishmeal, respectively) produced from larvae reared either on a commercial substrate (CC-MM) or partially reared on SMS (SMS-MM) (CC12.5, CC25, SMS12.5, and SMS25). An eight-week growth trial and a digestibility trial were conducted to evaluate growth performance, apparent digestibility coefficients (ADCs), nutrient retention, digestive enzyme activities and economic indicators. Mealworm meal partially produced on SMS (SMS-MM) exhibit a lower lipid content compared to the mealworm meal reared conventionally (CC-MM). No significant differences on growth performance were observed across diets; however, the 25 % inclusion of both mealworm meals resulted in reduced voluntary feed intake. Rainbow trout juveniles fed SMS-MM, especially at a 25 % dietary inclusion, exhibited higher apparent digestibility coefficients for dry matter, protein, ash, phosphorus, and energy. Additionally, fish fed the SMS25 diet showed higher trypsin activity than those fed the CTRL diet, while fish fed the CC25 showed improved feed efficiency, reduced hepatosomatic index, and higher digestible energy retention relative to the CTRL diet. Despite these benefits, the SMS25 and CC25 diets showed higher economic conversion ratios. Overall, these findings show that MM derived from larvae partially reared on SMS is nutritionally comparable to conventional MM and fishmeal in rainbow trout diets, with no adverse effects on zootechnical performance. The use of SMS as a rearing substrate represents a valuable approach to valorise an agro-industrial by-product. Thereby contributing to the circular economy and supporting a more resource-efficient and sustainable aquafeed production.
黄粉虫(tenbrio molitor)由于其良好的营养成分和减少的环境足迹,作为水产饲料配方的可持续替代品而受到关注。然而,高生产成本仍然是一个关键的制约因素。为了提高粉虫粕(MM)作为虹鳟鱼幼鱼饲料中鱼粉和植物油替代品的可持续性和降低生产成本,研究了利用农工副产物蘑菇废底物(SMS)部分替代传统粉虫幼虫饲养底物的方法。为虹鳟鱼幼鱼配制了5种等蛋白质(45 %)和等脂质(22 %)的试验饲料。对照日粮(CTRL)的设计反映了标准的商业配方。在CTRL饲粮基础上配制的另外四种饲粮包括12.5或25% %粉虫粉(分别取代50%和100% %的鱼粉),这些粉虫粉来自于在商业底物(CC-MM)上饲养的幼虫,或部分在SMS (SMS- mm)上饲养的幼虫(CC12.5、CC25、SMS12.5和SMS25)。通过8周的生长试验和消化率试验,评价生长性能、表观消化率系数、营养物质保留率、消化酶活性和经济指标。与常规饲养的粉虫粉(CC-MM)相比,部分用SMS饲养的粉虫粉(SMS- mm)的脂质含量较低。不同饲料对生长性能无显著差异;然而,25 %的粉虫膳食导致自愿采食量减少。虹鳟鱼幼鱼对干物质、蛋白质、灰分、磷和能量的表观消化系数较高,特别是饲料添加量为25% %时。此外,SMS25组的胰蛋白酶活性高于CTRL组,而CC25组的饲料效率、肝体指数和消化能保留率均高于CTRL组。尽管有这些好处,SMS25和CC25日粮的经济转化率更高。总体而言,这些研究结果表明,部分用SMS饲养的幼虫所产的鱼粉在营养上与虹鳟饲料中的传统鱼粉和鱼粉相当,对动物生产性能没有不利影响。SMS作为饲养基质的使用是使农工副产品增值的一种有价值的方法。从而为循环经济做出贡献,并支持更节约资源和可持续的水产饲料生产。

This study evaluated the impact of replacing soybean meal and part of maize with white lupin (Lupinus albus L.) seeds in growing lamb diet on animal performance, rumen fermentation, fatty acid (FA) metabolism, and meat quality. Twenty male lambs were assigned to a control diet (CON) or to an experimental diet (LUP) in which white lupin seeds were included at 350 g/kg dry matter (DM) of the total diet. In the LUP diet, soybean meal was completely replaced and 30 % of maize was substituted with lupin seeds. Diets were formulated to be similar in crude protein content and metabolizable energy. Over 56 days, lambs fed the white lupin-based diet exhibited significantly lower feed intake, final body weight, and average daily gain compared to control, likely due to reduced palatability and the presence of antinutritional factors. Moreover, white lupin-based diet altered ruminal fermentation by increasing acetate and butyrate proportions, and shifted FA biohydrogenation pathways, favoring the production of C18:1 t11 and C18:2 c9, t11 beneficial to human health. Meat from white lupin-fed lambs had a higher n-3 PUFA content and a reduced n-6/n-3 ratio, with no detrimental effects on meat oxidative stability or color during storage. These findings suggest that fully replacing soybean meal and 30 % of maize with white lupin seeds could beneficially influence meat lipid quality, though adjustments to diet formulation are necessary to mitigate negative effects on feed intake and growth.
本试验旨在评价生长羔羊饲粮中用白露平种子替代豆粕和部分玉米对动物生产性能、瘤胃发酵、脂肪酸代谢和肉品质的影响。选取20只雄性羔羊,分别饲喂对照饲粮(CON)和试验饲粮(LUP),在试验饲粮中添加干物质(DM)为350 g/kg的白罗苹籽。在LUP日粮中,豆粕被完全替代,30% %的玉米被罗苹籽替代。饲粮的粗蛋白质含量和代谢能相近。在56天的试验中,与对照组相比,饲喂白色羽扇豆素的羔羊的采食量、最终体重和平均日增重显著降低,这可能是由于适口性降低和抗营养因子的存在。此外,以白色羽扇豆素为基础的饲粮通过增加乙酸和丁酸比例改变了瘤胃发酵,改变了FA的生物加氢途径,有利于C18:1 t11和C18:2 c9的产生,对人体健康有益。饲喂羽豆素的白色羔羊肉中n-3 PUFA含量较高,n-6/n-3比值降低,但在贮藏过程中对肉的氧化稳定性和颜色没有不利影响。这些研究结果表明,用白罗苹籽完全替代豆粕和30% %的玉米有利于改善肉脂质,但需要调整日粮配方以减轻对采食量和生长的负面影响。

The aim of this study was to verify whether hexamine can be replaced by sodium benzoate in sodium nitrite-based silage additives in a difficult to ensile forage. Guinea grass cv Aries II (dry matter (DM) concentration = 185 g/kg fresh matter (FM) and fermentability coefficient = 218) was mowed at 60 d of regrowth, chopped, and divided into 24 piles (6 kg fresh matter (FM)/pile) to receive one of the six treatments: no additive (CON); sodium nitrite (0.9 g/kg FM) + hexamine (0.6 g/kg FM) (NH); sodium nitrite (0.9 g/kg FM) + sodium benzoate (0.6 g/kg FM) (NB6); sodium nitrite (0.9 g/kg FM) + sodium benzoate (0.9 g/kg FM) (NB9); sodium nitrite (0.9 g/kg FM) + sodium benzoate (1.2 g/kg FM) (NB12) and sodium nitrite (0.9 g/kg FM) + sodium benzoate (1.5 g/ kg FM) (NB15). Each treatment was applied to 4 piles (replicates). Treated forage was ensiled in 7.2-L experimental silos, and stored for 66 d. Expectedly, the NH was able to inhibit Clostridium development, as it decreased ammonia, n-butyric, i-butyric, i-valeric and n-valeric acids, and DM loss during fermentation. Additionally, the NH and treatments providing greater doses of sodium benzoate (i.e., NH12 and NH15) enhanced the in vitro DM digestibility and the proportion of rumen undegradable protein compared to CON. However, in treatments where hexamine was replaced with sodium benzoate, silages showed typical characteristics of clostridial fermentation, such as low concentration of lactic acid and high concentrations of n-butyric acid and higher homologues. Silage aerobic stability was longer than 7 d for all treatments. In conclusion, sodium benzoate, even when added at high doses, could not replace hexamine to efficiently prevent undesirable fermentations in guinea grass silages with low DM content.
本研究的目的是验证在一种难青贮饲料中,苯甲酸钠是否可以替代亚硝酸钠基青贮添加剂。再生后60 d,干物质(DM)浓度= 185 g/kg鲜物质(FM),发酵系数= 218,割草,剁碎,分成24堆(6 kg鲜物质(FM)/堆),分别进行6个处理:不添加添加剂(CON);亚硝酸钠(0.9 g/kg FM) + hexamine(0.6 g/kg FM) (NH);亚硝钠(0.9 g/kg FM) + 苯甲酸钠(0.6 g/kg FM) (NB6);亚硝钠(0.9 g/kg FM) + 苯甲酸钠(0.9 g/kg FM) (NB9);亚硝酸钠(0.9 g/kg FM) + 苯甲酸钠(1.2 g/kg FM) (NB12)和亚硝酸钠(0.9 g/kg FM) + 苯甲酸钠(1.5 g/ kg FM) (NB15)。每个处理处理4个桩(重复)。处理后的饲料在7.2 l的试验筒仓中青贮66 d。预期,NH能够抑制梭状芽孢杆菌的发育,因为它减少了发酵过程中的氨、正丁酸、正丁酸、戊酸和正戊酸,并减少了DM的损失。此外,与对照组相比,NH和提供大剂量苯甲酸钠(即NH12和NH15)的处理提高了体外DM消化率和瘤胃不可降解蛋白的比例。然而,在苯甲酸钠替代NH的处理中,青贮表现出典型的梭菌发酵特征,如低浓度的乳酸和高浓度的正丁酸和更高的同源物。各处理青贮好氧稳定性均大于7 d。综上所述,在低干物质含量的豚草青贮饲料中,即使添加高剂量的苯甲酸钠,也不能代替苯甲酸钠有效地防止不良发酵。

The present study conducted to evaluate the effects of guar meal concentrate (Gmc) as substitute of fish meal on growth, digestive enzymes activity, and intestinal histological of seabream (Sparus aurata). Fish fed four experimental diets with a protein level set at 45 % for 12 weeks by replacing the 0 % (Gu0), 10 % (Gu1), 20 % (Gu2), and 30 % (Gu3) of fish meal with Gmc. The results showed that fish fed Gu2 elevated growth and feed utilization indices, respectively. Linear regression analysis revealed a significant negative relationship between Gmc inclusion and specific growth rate, and a positive relationship with feed conversion ratio. The protein body composition content rose when fish fed Gu2 and the lowest body lipid content noticed when seabream fed Gu0, the activity of the digestive enzymes lipase and amylase were reduced when seabream were fed Gmc at all levels. According to this trial, it is advantageous to supplement seabream diets with 10–12 % Gmc in formulated and balanced diets.

Nutritive value of fodder beet for broilers chickens 饲料用甜菜对肉鸡的营养价值
IF 2.7 2区 农林科学 Q1 AGRICULTURE, DAIRY & ANIMAL SCIENCE Pub Date : 2025-12-09 DOI: 10.1016/j.anifeedsci.2025.116604

An experiment was conducted to determine the apparent metabolisable energy (AME), nitrogen-corrected AME (AMEn) and the standardised ileal digestible content of amino acids in fodder beet (FB). Three maize-soybean-based diets were formulated, a basal diet (FB0), the basal diet supplemented with 12.5 % of FB (FB12.5), and the basal diet supplemented with 25 % of FB (FB25). Each diet was randomly allocated to six replicate cages with six birds per cage and fed from days 14–21. Titanium dioxide (4 g/kg) was included in all diets as an indigestible marker for the measurement of marker-based AME and ileal nutrient digestibility. The total collection (TC) method was also used for the measurement of AME. A regression method was used to determine the nutritive value of FB. The AME and AMEn of FB were determined to be 9.63 MJ/kg and 9.36 MJ/kg, respectively, using the TC method, and 7.97 MJ/kg, 7.79 MJ/kg, respectively, using the marker method. The apparent ileal crude protein (CP) and gross energy (GE) content of FB were 56.4 g/kg and 11.2 MJ/kg, respectively. Standardised ileal digestible amino acid content was higher for glutamic acid (21.1 g/kg) while it was lower for sulfur containing amino acids (-0.1 to −0.4 g/kg). In conclusion, nutritive value of FB was determined for 14–21 day old broilers using regression method. Further studies are needed to validate the current findings, and to determine the optimal inclusion level of FB in poultry diets.
本试验旨在测定饲用甜菜的表观代谢能(AME)、氮校正AME (AMEn)和氨基酸的标准回肠可消化含量。配制3种以玉米-大豆为基础的饲粮,分别为基础饲粮(FB0)、基础饲粮中添加12.5 % FB (FB12.5)和基础饲粮中添加25 % FB (FB25)。每种饲粮随机分配到6个重复笼中,每个重复笼6只鸟,从第14-21天开始饲喂。在所有饲粮中添加二氧化钛(4 g/kg)作为不消化标记物,测定基于标记物的AME和回肠营养物质消化率。总收集(TC)法测定AME。采用回归分析的方法确定了FB的营养价值。用TC法测定FB的AME和AMEn分别为9.63 MJ/kg和9.36 MJ/kg,用标记法测定FB的AME和AMEn分别为7.97 MJ/kg和7.79 MJ/kg。FB的表观回肠粗蛋白质(CP)和总能(GE)含量分别为56.4 g/kg和11.2 MJ/kg。标准回肠可消化氨基酸含量以谷氨酸较高(21.1 g/kg),含硫氨基酸较低(-0.1 ~ - 0.4 g/kg)。综上所述,采用回归法确定了FB对14-21日龄肉仔鸡的营养价值。需要进一步的研究来验证目前的发现,并确定家禽日粮中FB的最佳添加水平。

Two experiments were conducted to evaluate the effects of an inoculant containing Lentilactobacillus hilgardii CNCM-I-4785, Lentilactobacillus buchneri NCIMB 40788, Pediococcus pentosaceus NCIMB 12455, β-glucanase, and xylanase on the fermentation profile, aerobic stability, and nutrient degradability of whole-plant corn silage. In Experiment 1, a brown midrib corn hybrid was harvested at 35.4 % dry matter (DM) and ensiled for 14 and 90 d. In Experiment 2, a conventional corn hybrid was harvested at either a low DM content (26.2 %) or a high DM content (39.7 %) and ensiled for 30, 60, 120, and 180 d. In Experiment 1, inoculation increased acetic acid concentrations at both 14 and 90 d and markedly improved aerobic stability at 90 d (+ 360 h). In Experiment 2, inoculation increased acetic acid concentrations at 60, 120, and 180 d in both DM levels and at 30 d only in low DM. Inoculation improved aerobic stability at 30 (+ 30 h), 120 (+111 h), and 180 d (+ 89 h) across both DM levels. At 60 d, the increase in stability by inoculation was greater in low DM (+ 58 h) than in high DM silage (+ 36 h). Inoculation enhanced starch degradability by 9.8 %age points at 90 d in Experiment 1, and by 4.7 and 2.7 %age points at 120 and 180 d, respectively, in Experiment 2. Overall, the inoculant effectively enhanced aerobic stability and starch degradability across two hybrids and three distinct DM levels.
通过两个试验,研究了含hilgardii慢乳杆菌CNCM-I-4785、布氏慢乳杆菌NCIMB 40788、戊糖Pediococcus NCIMB 12455、β-葡聚糖酶和木聚糖酶的接种剂对玉米全株青贮发酵特性、好氧稳定性和养分降解性的影响。在试验1中,棕色中脉玉米杂交种在干物质含量为35.4% %时收获,青贮14和90 d。在试验2中,常规玉米杂交种在低干物质含量(26.2 %)或高干物质含量(39.7 %)下收获,青贮30、60、120和180 d。在试验1中,接种可提高14和90 d的乙酸浓度,并显著提高90 d(+ 360 h)的好氧稳定性。在试验2中,在DM水平的60、120和180天,以及在低DM水平的30天,接种提高了乙酸浓度。在DM水平的30(+ 30 h)、120(+111 h)和180 d(+ 89 h)时,接种提高了好氧稳定性。60 d时,低DM青贮组(+ 58 h)比高DM青贮组(+ 36 h)增加的稳定性更大。在试验1中,接种可使淀粉在90 d时的降解率提高9.8%,在试验2中,接种可使淀粉在120和180 d时的降解率分别提高4.7%和2.7%。总的来说,接种剂有效地提高了两个杂交种和三个不同DM水平的好氧稳定性和淀粉降解性。
