The demand for energy, water and food will continuously increase, as the prediction states that 2.5 billion people will be added to the world population by 2050, representing not only an increase in the consumption but also more waste production, greenhouse gas (GHG) emissions and depletion of natural resources. Taking into account that renewable sources of energy can help to overcome these challenges and diversify the energy matrix in the countries, this paper aims at analyzing the biogas potential in Brazil and the United States, especially in the livestock sector, and its benefits in the environmental, social and economic aspects. Both countries are among the top five countries globally in terms of water availability, energy consumption and food production. Until 2050, the world consumption of meat will have a significant increase: 206% of poultry meat, 56% of pork meat and 47% of beef meat, augmenting the need for sustainable management of waste and manure. This scenario can become a sustainable opportunity for biogas implementation, which provides multiple economic, environmental and social benefits for farmers, businesses and communities, including production of electrical, thermal and vehicular energy, production of high-quality biofertilizer, reduction of ground and surface water pollution and reduction of GHG emissions, and foments new income for the farmers, among others. A new concept is presented in this article to make biogas systems feasible, i.e., biogas condominiums, as small and medium-scale farms by themselves usually would not be able to afford the investments. This arrangement can bring benefits for the whole biogas supply chain that includes farmers, agroindustry, providers and local community.
对能源、水和食物的需求将不断增加,据预测,到2050年世界人口将增加25亿,这不仅意味着消费的增加,也意味着更多的废物产生、温室气体排放和自然资源的枯竭。考虑到可再生能源可以帮助克服这些挑战并使各国的能源矩阵多样化,本文旨在分析巴西和美国的沼气潜力,特别是在畜牧业中的潜力,及其在环境、社会和经济方面的效益。两国在水资源供应、能源消耗和粮食生产方面均位居全球前五。到2050年,世界肉类消费量将显著增加:禽肉消费量为206%,猪肉消费量为56%,牛肉消费量为47%,增加了对废物和粪便可持续管理的需求。这种情况可以成为实施沼气的可持续机会,为农民、企业和社区提供多种经济、环境和社会效益,包括生产电力、热能和汽车能源,生产高质量的生物肥料,减少地面和地表水污染,减少温室气体排放,并为农民创造新的收入,等等。本文提出了一个使沼气系统可行的新概念,即沼气公寓,因为中小型农场本身通常无法承担投资。这种安排可以为包括农民、农业工业、供应商和当地社区在内的整个沼气供应链带来好处。

Sericea lespedeza (Lespedeza cuneata (Dum. Cours.) G. Don.) has historically been called “poor man’s alfalfa”, because of its ability to grow on marginal soil with the minimal inputs of lime or fertilizer. With recent research detailing the potential health benefits of this forage to animals, it may be time for a new nickname. Although sericea lespedeza has been used for soil conservation and as an inexpensive (low-input) source of pasture or hay crop for nearly 100 years, research over the last 10-15 years has demonstrated the excellent bioactivity of this plant against infection with gastrointestinal nematodes (Haemonchus contortus) and protozoan parasites (Eimeria spp.) in livestock. This bioactivity, which has been attributed to a unique type of condensed tannins (CT), has been confirmed in both fresh (grazed) and dried (hay, meal, pellets) forms of sericea lespedeza in a number of studies with sheep, goats, and cattle. There is on-going research with this forage to determine the effect of ensiling on its bioactive properties and to validate its anti-parasitic effects on-farm. Future research will focus on determining the mode of action of sericea lespedeza tannins against internal parasites and the interplay between the nutritional value and the health benefits of this plant.
胡枝子(lespedeza cuneata)课程)。)历来被称为“穷人的紫花苜蓿”,因为它能够在边际土壤上以最少的石灰或肥料投入生长。最近的研究详细说明了这种草料对动物的潜在健康益处,也许是时候给它起个新绰号了。尽管近100年来,丝蚕一直被用于土壤保持,并作为一种廉价(低投入)的牧草或干草作物来源,但过去10-15年的研究表明,这种植物具有抗胃肠道线虫(Haemonchus扭曲)和牲畜原生动物寄生虫(艾美耳虫属)感染的良好生物活性。这种生物活性归因于一种独特类型的浓缩单宁(CT),在对绵羊、山羊和牛进行的多项研究中,已在新鲜(放牧)和干燥(干草、饲料、颗粒)形式的蚕丝中得到证实。目前正在对这种饲料进行研究,以确定青贮对其生物活性特性的影响,并验证其在农场上的抗寄生虫作用。未来的研究将集中在确定丝蚕单宁对体内寄生虫的作用模式以及该植物的营养价值和健康益处之间的相互作用。

Secondary metabolites produced by plants can be used in popular medicine, as well they can interact with plants and other organisms, in which case they are called allelochemicals and influence the neighboring ecosystem. This work aimed to evaluate the allelopathic effects of Schinus molle L. species widely used in reforestation and urban afforestation. Therefore, leaves of S. Molle were collected from different populations located at Alfenas and Nepomuceno in Minas Gerais, Brazil. Cypselae of lettuce (Lactuca sativa L.) were germinated in biochemical oxygen demand (BOD) chamber at 25 °C with a photoperiod of 12 h under different extracts concentrations. The experiment was performed in factorial design (2 × 4) with two kinds of extracts (aqueous and ethanol) and four concentrations (2.5, 5, 10 and 20 mg/mL) in randomized blocks. The variables analyzed were germination (%), germination speed index (GSI), % of normal seedlings, root length, fresh biomass and dry biomass. Changes in the cell cycle in meristematic cells of the used model were also evaluated. Concentration-dependent effect on all parameters was observed, with the exception of dry biomass exposed to ethanol extract. The root elongation parameter was different between the extracts even in lower concentrations, thus indicating that this is the most sensitive parameter of this species. Toxic effect from S. molle extracts was observed in all parameters regardless the kind of pruning management or method of extraction (water or ethanol).
植物产生的次生代谢物可以用于大众医药,也可以与植物和其他生物相互作用,在这种情况下,它们被称为化感化学物质,并影响邻近的生态系统。本文旨在评价在城市绿化和再造林中广泛应用的沙棘的化感作用。因此,在巴西米纳斯吉拉斯州的Alfenas和Nepomuceno的不同种群中收集了S. Molle的叶片。以莴苣(Lactuca sativa L.)为材料,在生化需氧量(BOD)箱中,在25℃条件下,不同提取物浓度下,光周期为12 h。试验采用因子设计(2 × 4),采用两种提取液(水提液和乙醇提液)和四种浓度(2.5、5、10和20 mg/mL)随机分组。分析的变量为发芽率(%)、发芽速度指数(GSI)、正常苗百分比、根长、新鲜生物量和干生物量。我们还对模型中分生组织细胞的细胞周期变化进行了评价。除了暴露于乙醇提取物的干生物量外,所有参数都观察到浓度依赖效应。即使在较低浓度下,根伸长参数在不同提取物之间也存在差异,表明这是该物种最敏感的参数。无论修剪方式或提取方法(水或乙醇)如何,在所有参数下均观察到枸杞提取物的毒性作用。

A study was conducted on reducing the yield loss of wheat due to leaf rust caused by Puccinia triticina with foliar application of fungicides during the 2014-2015 and 2015-2016 growing seasons at the Wheat Research Institute in Faisalabad, Pakistan. Three fungicides: Folicur (tebuconazole) at 300 mL/ha, Nativo (tebuconazole + trifloxystrobin) at 300 g/ha and Tilt (propiconazole) at 500 mL/ha were applied single or two times to Morocco and Sehar-06 wheat varieties used in the trial. The trial plots were first sprayed at the Zadok’s scale (ZS) 3 stage and second sprayed between ZS 4.3 and 5.4 stages. The greenness of the trial crop was measured using GreenSeeker. Foliar application of fungicides significantly reduced the loss of grain yield and 1,000-grain weight (TGW) of wheat due to leaf rust in comparison to the control without fungicides application. Of the three fungicides, two times spray of Nativo reduced the grain yield loss of leaf rust susceptible mega wheat variety Sehar-06 by 45%-56% and the loss of TGW by 42%, also giving the highest marginal return in the trial. Single application of Nativo was equally effective as two times spray of Folicur in reducing the loss of wheat grain yield. Two times spray of Folicur was found to be the second choice of fungicide for reducing the yield loss of wheat. The research identified suitable fungicides for reducing the yield loss of wheat due to leaf rust and also generated important scientific knowledge required to manage a sudden outbreak of leaf rust to ensure food security.
巴基斯坦费萨拉巴德小麦研究所在2014-2015年和2015-2016年两个生长季节对小麦进行了叶面施用杀菌剂以减少小麦因小麦锈病造成的产量损失的研究。3种杀菌剂:Folicur (tebuconazole) 300毫升/公顷、Nativo (tebuconazole + trifloxystrobin) 300克/公顷和Tilt (propiconazole) 500毫升/公顷,分别施用于试验中使用的摩洛哥和Sehar-06小麦品种。试验田在Zadok 's scale (ZS) 3期进行第一次喷施,ZS 4.3 ~ 5.4期进行第二次喷施。试验作物的绿色度是用GreenSeeker测量的。与不施用杀菌剂的对照相比,叶面施用杀菌剂显著降低了小麦因叶锈病造成的产量损失和千粒重损失。在3种杀菌剂中,2次喷施Nativo可使叶锈病易感特级小麦sehar06的产量损失降低45% ~ 56%,TGW损失降低42%,边际收益最高。在减少小麦籽粒产量损失方面,单次喷淋与两次喷淋Folicur效果相同。Folicur二次喷施是减少小麦产量损失的第二选择药剂。这项研究确定了合适的杀菌剂,以减少由于叶锈病造成的小麦产量损失,并产生了管理叶锈病突然爆发以确保粮食安全所需的重要科学知识。

This experiment was carried out to determine feed intake and digestibility of grazing sheep on pasture. A total of 14 animals randomly divided into two groups with seven animals each group were used in the experiment. Digestibility of pastures was determined using two types of markers—alkane (C32-C36) and chromium oxide. Dry matter intake (DMI) was 717.22 g/d based on chromium oxide method in the experiment, while according to alkane method, DMI was 965.93 g/d and 1,051.07 g/d for C32 and C36, respectively. In conclusion, pastures met 74%-81% of crude protein (CP) and 57%-61% of energy requirements of lambs grazing on Yuzuncu Yil University pasture, who are mid-quality and 4-7 month-old with a 275 g/d expected daily gain. It was calculated that when 628-693 g/d of barley is given, both CP and metabolizable energy (ME) requirements of animals can be met.
本试验旨在测定放牧羊在牧场上的采食量和消化率。试验选用14只动物,随机分为两组,每组7只。采用烷烃(C32-C36)和氧化铬两种标记物测定牧草的消化率。本试验采用氧化铬法测定C32和C36干物质采食量为717.22 g/d,采用烷烃法测定C32和C36干物质采食量为965.93 g/d和1051.07 g/d。综上所述,4 ~ 7月龄、预期日增重275 g/d的中等品质羔羊,在郁祖库大学牧场放牧,其粗蛋白质需要量可满足74% ~ 81%,能量需要量可满足57% ~ 61%。计算得出,饲喂628 ~ 693 g/d的大麦,可满足动物对CP和代谢能(ME)的需求。

When comparing more than two groups means, the analysis of means (ANOM) can be used as an alternative to the one-way analysis of variance (ANOVA) F test. The ANOM provides a “confidence interval type of approach” that allows it to determine which, if any, of the x groups has a significantly different mean from the overall average of all the group means combined. The aim of this study was to show the application of a statistical technique (ANOM), mostly used by agriculture, to determine differences between red meat production by period in Turkey. The production quantities of goat meat, mutton, buffalo meat and beef between the years 2010 and 2016 according to the period were taken from Turkish Statistical Institute (TSI). As a result, the difference between meat productions was found to be significant.
当比较两组以上的均值时,均值分析(ANOM)可以用作单向方差分析(ANOVA) F检验的替代方法。ANOM提供了一种“置信区间类型的方法”,允许它确定x组中哪一个(如果有的话)的平均值与所有组的平均值组合的总体平均值有显著不同。本研究的目的是展示主要用于农业的统计技术(ANOM)的应用,以确定土耳其不同时期红肉产量之间的差异。2010年至2016年期间,羊肉、羊肉、水牛肉和牛肉的产量取自土耳其统计研究所(TSI)。结果发现,肉制品之间的差异是显著的。
