Agricultural transformation in Poland and Bulgaria, both characterized by unique farm structures compared to the old EU, has been a policy challenge for the Common Agricultural Policy (CAP) even before integration. Eurostat and Comtrade data over 2000 to 2016/2017 have been used to analyse agricultural restructuring at farm level, relating it to growth trends in agro-processing units and eventually to competitiveness in agricultural exports and trade specialization. CAP payment instruments, especially DPs have influenced farm restructuring, farming practices and income in both Poland and Bulgaria. Distinctive farm structures have evolved that have caused polarization and influenced productivity. Large farms are the main beneficiaries of farm aids and this polarization continues in the agro-industry sector as well. Multinational agro-firms, though insignificant in number are found to monopolise agro-based production in almost all the food processing sub-sectors in both the member countries. In terms of trade competitiveness indices, export specialization of agri-commodities has reduced in both members over 2000-2017, shares of processed commodities in exports with specialization have increased for Poland while Bulgaria has gained in medium-processing capabilities. For policy implications, small farms need to form producer groups and coordinate with small producers to increase both farm and firm level productivity. The subsidiarity principle of new CAP can be utilized by member states to facilitate this.
波兰和保加利亚的农业转型与旧欧盟相比具有独特的农业结构,甚至在一体化之前就已经成为共同农业政策(CAP)的政策挑战。欧盟统计局和Comtrade在2000年至2016/2017年期间的数据被用于分析农场层面的农业结构调整,将其与农业加工单位的增长趋势联系起来,并最终与农业出口和贸易专业化的竞争力联系起来。在波兰和保加利亚,共同农业政策的支付手段,特别是发展补贴对农业结构调整、耕作方式和收入都产生了影响。独特的农场结构已经形成,造成了两极分化,影响了生产力。大农场是农业援助的主要受益者,这种两极分化在农用工业部门也在继续。跨国农业公司虽然数量微不足道,但在两个成员国几乎所有的食品加工分部门都垄断了以农业为基础的生产。在贸易竞争力指数方面,2000年至2017年期间,两个成员国农产品出口专业化程度有所下降,波兰加工商品在专业化出口中所占份额有所增加,而保加利亚的中等加工能力有所提高。就政策影响而言,小农场需要组成生产者团体,并与小生产者协调,以提高农场和公司一级的生产力。成员国可以利用新共同农业政策的辅助原则来促进这一点。

The aim of this study was to determine the correlations between the output parameters of the in sacco method and the CNCPS method (Cornell Net Carbohydrate and Protein System). Both methods were tested on 106 samples from the feeds classified into following categories: extracted meal and cakes, cereals, legumes, maize and alfalfa silage, other silages, DDGS (dried distiller’s grains with solubles), oilseeds and various hays. The effective degradability of crude protein (EDg CP) by the in sacco method varied depending on the type of feed from 44.97% (hays) to 82.59% (alfalfa silage). The lowest degradation parameter of rapidly degraded fraction (a=24.3%) and the highest potentially degraded fraction (b=70.52%) were found in oilseeds. Five nitrogen fractions (A, B 1 , B 2 , B 3 , C) were determined according to the CNCPS method. Fraction A (NPN – non-protein nitrogen) was different in examined feed with the highest in silages (44.95% of the total CP). Fraction B 2 represented in tested feeds the highest part of the total CP, (except for silages, legumes, and oilseeds). Fraction B 3 ranged from 1.96% (legumes) to 19.25% (hays) of the total CP. The correlation between EDg CP and soluble fractions was low (r=0.5464) in concentrate feeds, the correlation between EDg and soluble fractions was (r=0.6323) also low in forages.
本研究的目的是确定甘蔗法和CNCPS法(康奈尔净碳水化合物和蛋白质系统)输出参数之间的相关性。这两种方法在106种饲料样品上进行了测试,这些饲料分为以下几类:提取粕和蛋糕、谷物、豆类、玉米和苜蓿青贮饲料、其他青贮饲料、DDGS(干酒糟和可溶物)、油籽和各种干草。不同饲料类型的青贮法对粗蛋白质(EDg CP)的有效降解率为44.97%(干草)~ 82.59%(苜蓿青贮)。油籽中快速降解组分的降解参数最低(a=24.3%),潜在降解组分的降解参数最高(b=70.52%)。采用CNCPS法测定了5个氮组分(A、b1、b2、b3、C)。A组分(NPN -非蛋白氮)不同,青贮饲料中最高,占总CP的44.95%。在试验饲料中,b2是总CP的最高部分(青贮饲料、豆类和油籽除外)。在精料中,EDg CP与可溶性组分的相关性较低(r=0.5464),在牧草中,EDg CP与可溶性组分的相关性也较低(r=0.6323)。

Wheat is one of the most important crops in the world, its products, especially fermented baked goods, take a major role in the diet. These products require strong flour. In Syria, about 20 – 25% of improved durum wheat is blended with soft wheat to increase the strength of the flour. Laccase enzyme, is one of the important oxidative enzymes, which is added to increase the strength of the dough. Several devices have been used to evaluate flour and measure the properties of dough, but none of them is able to predict all the properties in a single test one. A new instrument Mixolab dough characterizer has been developed to measure the dough properties and the pasting behavior of flour at the same time. Hence, in the present research Mixolab dough characterizer was used to assess the effect of the addition of laccase enzyme and blending of durum and soft Syrian wheat on the rheological properties of wheat flour (80% extraction). The results showed that the values of C 2 (decrease in dough consistency due to excessive mixing), water absorption, and dough development time increase after the addition of laccase enzyme and blending durum and soft wheat, as well as the dough stability increases too, therefore, it can be concluded that, both the addition of laccase and blending durum and soft wheat increase dough strength, but the addition of laccase treatment has higher values of dough stability and gluten index compared to blend flour. The effect of the two treatments on the properties of the starch differed; the values of C 3 (starch gelatinisation), C 4 (gel stability), and C 5 (starch retrogradation) are increasing with laccase addition, while these values are reducing with the blending of durum and soft wheat.
小麦是世界上最重要的农作物之一,其产品,特别是发酵烘焙食品,在人们的饮食中占有重要地位。这些产品需要高筋面粉。在叙利亚,约20 - 25%的改良硬粒小麦与软粒小麦混合,以增加面粉的强度。漆酶是一种重要的氧化酶,加入它可以增加面团的强度。人们已经使用了几种设备来评估面粉和测量面团的性质,但没有一种设备能够在一次测试中预测所有的性质。研制了一种新型的混合式面团表征仪,可以同时测量面团的性质和面粉的成糊化行为。因此,本研究采用Mixolab面团表征剂来评价漆酶的添加以及硬粒小麦和软叙利亚小麦的混合对小麦粉(80%提取)流变学特性的影响。结果表明:加入漆酶及掺硬膜与软麦后,面团的c2值(因过度搅拌导致面团稠度下降)、吸水率、面团发育时间均有所增加,面团稳定性也有所提高,因此可以认为,掺漆酶及掺硬膜与软麦均能提高面团强度;但加入漆酶处理后的面团稳定性和面筋指数均高于混合面粉。两种处理对淀粉性质的影响不同;c3(淀粉糊化)、c4(凝胶稳定性)和c5(淀粉降解)的值随着漆酶的添加而增加,而这些值随着硬粒和软粒小麦的混合而降低。

Bedding material has a significant effect on life, health and production of broiler chicken since they are in direct contact with litter. When condition of litter is poor, it increases an occurrence of pododermatitis. Birds living in chronic pain move less and consequently eat and drink less and because of that their production is less efficient. The aim of this review is to compare different bedding materials used in Europe and elsewhere in the world and to evaluate their effects on production parameters, health and animal welfare. During the last years, a lot of research has been done using both traditional and alternative bedding materials. A significant part of materials was evaluated as suitable or improving production parameters. There is an evidence that at least one quarter of broiler chicken live in constant pain due to footpad dermatitis, joint inflammations or other locomotory disorders for more than one third of their live. The health of the locomotory system is the major challenge for improving poultry welfare. Several substrates can be used as bedding material for poultry. In general, we can conclude that, the finer particles are the lower is the occurrence of pododermatitis. However optimal bedding material must be able to absorb excess water but also to be dried properly. Another important aspect of animal welfare is the opportunity to manifest their natural behaviour. Research clearly shows that poultry prefer to perform dustbathing only in dry and dusty substrate.
床上材料与鸡粪直接接触,对肉鸡的生活、健康和生产有重要影响。当产仔条件差时,会增加足皮炎的发生。生活在慢性疼痛中的鸟类活动较少,因此吃得少,喝得少,因此它们的生产效率较低。本综述的目的是比较欧洲和世界其他地方使用的不同床上用品材料,并评估其对生产参数、健康和动物福利的影响。在过去的几年里,人们对传统和替代床上材料进行了大量的研究。相当一部分材料被评价为适合或改善生产参数。有证据表明,至少有四分之一的肉鸡生活在脚垫皮炎、关节炎症或其他运动障碍造成的持续疼痛中,持续时间超过三分之一。运动系统的健康是提高家禽福利的主要挑战。几种基质可用作家禽的床上材料。总的来说,我们可以得出结论,颗粒越细,脚皮炎的发生率越低。然而,最理想的床上材料必须能够吸收多余的水分,但也要适当干燥。动物福利的另一个重要方面是有机会展示它们的自然行为。研究清楚地表明,家禽只喜欢在干燥和多尘的基质上进行除尘。

A comparative phenological evaluation of a group of 32 vine varieties for white wines has been carried out. It has been found through the application of cluster analysis, PCA and factor analysis that, depending on the duration of the separate phenophases and periods in days, the studied varieties are grouped into four clusters. The phenological indicators are transformed into three factors, with a different degree of influence on the grouping of varieties, which explain 74% of the total variation. The most important for the grouping of varieties are the phenophase berry growth, and the periods flowering – berry softening and berry softening – technological maturity. In order to increase the efficiency of selection, it is advisable to cross varieties for white wines characterized by optimal phenological parameters, and belonging to clusters most remote from each other

In some European countries, the Western corn rootworm, Diabrotica virgifera virgifera , and the cereal leaf beetle, Oulema melanopus , are present in maize stands in high population density, occasionally causing damage of the crops. Susceptibility of adults of these species and larvae of the cereal leaf beetle to the commercially available product Naturalis® based on Beauveria bassiana strain ATCC 74040 was explored in laboratory conditions. The results of the bioassays showed that the fungal strain caused the highest corrected mortality on O. melanopus larvae with average values above 95% for all conidia concentrations (from 2.3 × 10 2 to 2.3 × 10 7 conidia/ml) tested. For the adults of the two pests, the average mortality increased positively with concentration of conidia and the values ranges from 9.5% to 94.2% for O. melanopus (concentrations from 2.3 × 10 2 to 2.3 × 10 7 conidia/ml) and from 19.3% to 92.4% for D. v. virgifera (concentrations from 2.3 × 10 3 to 2.3 × 10 7 conidia/ml). Accordingly, the LC 50 values for O. melanopus larvae and adults and D. v. virgifera adults were determined as 4.6, 8.3 × 10 4 and 4.3 × 10 5 conidia/ml, respectively. Further studies to confirm the susceptibility of the larvae of the cereal leaf beetle to Naturalis® under field conditions should be conducted.
在一些欧洲国家,西部玉米根虫(Diabrotica virgifera virgifera)和谷物叶甲虫(Oulema melanopus)在玉米林内的种群密度很高,偶尔会对作物造成损害。在实验室条件下,研究了这些品种的成虫和谷物叶甲虫幼虫对基于白僵菌ATCC 74040菌株的市售产品Naturalis®的敏感性。生物测定结果表明,该真菌菌株对黑纹天蛾幼虫的校正死亡率最高,在所有分生孢子浓度(2.3 × 10 2 ~ 2.3 × 10 7孢子/ml)范围内,校正死亡率均在95%以上。两种害虫成虫的平均死亡率均随分生孢子浓度的增加而增加,黑纹姬蚊的平均死亡率为9.5% ~ 94.2%(浓度为2.3 × 10 2 ~ 2.3 × 10 7分生孢子/ml),绿纹姬蚊的平均死亡率为19.3% ~ 92.4%(浓度为2.3 × 10 3 ~ 2.3 × 10 7分生孢子/ml)。据此测定黑纹姬蚊幼虫和成虫的lc50分别为4.6、8.3 × 10.4和4.3 × 10.5分生孢子/ml。在田间条件下,应进一步研究禾叶甲虫幼虫对Naturalis®的敏感性。

Further studies to confirm the susceptibility of the larvae of the cereal leaf beetle to Naturalis® under field conditions should be conducted.","PeriodicalId":51685,"journal":{"name":"Journal of Central European Agriculture","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70974168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A survey in olive orchards in Istria (Croatia) was carried out from 2016 to 2018 to investigate pathogens potentially associated with olive decline and dieback. In nine orchards, canker-like symptoms were recorded on olive trunks and branches. Six fungal species were isolated from cankers: Geosmithia sp., Diaporthe sp., Diatrype stigma , Diplodia seriata , Neofusicoccum parvum , and Pseudophaeomoniella oleae . Pathogenicity tests were conducted in a greenhouse, on branches of 4-year-old local cultivar ‘Buza’. Eight months after branch inoculation, D. seriata showed to be the most aggressive, causing an average of 67 mm long lesion. N. parvum caused 31 mm long lesion, while Diaporthe sp. showed only weak aggressiveness, causing 3 mm long lesion. Diatrype stigma , P. oleae and Geosmithia sp. did not cause any symptoms on inoculated plants. This is the first report of Neofusicoccum parvum and Diaporthe sp. as pathogens on olive in Istria (Croatia).
2016年至2018年在伊斯特拉(克罗地亚)的橄榄果园进行了一项调查,以调查可能与橄榄衰退和枯死有关的病原体。在9个果园中,在橄榄树干和树枝上记录了类似溃疡病的症状。从溃疡病中分离到6种真菌,分别为:土霉属(Geosmithia sp.)、土霉属(Diaporthe sp.)、柱头型(diatype stigma)、seriata型(Diplodia seriata)、Neofusicoccum parvum和Pseudophaeomoniella oleae。在温室中对当地4年栽培品种‘Buza’的枝条进行了致病性试验。分枝接种8个月后,灰散球菌表现出最强的侵袭性,造成平均67毫米长的损伤。N. parvum引起31 mm长的病变,而Diaporthe sp.侵袭性较弱,引起3 mm长的病变。病柱头型、油橄榄和土藓属在接种植株上未引起任何症状。这是克罗地亚伊斯特里亚地区首次报道橄榄上的小新褐虫和Diaporthe sp.作为病原菌。

Calf behaviour in rearing systems is an important indicator of calf welfare and influences efficient dairy production. In this study, the behavioural patterns of dairy calves in outdoor individual pen-and-shelter units were investigated. The study was done over 12 months with 683 Simmental-Fleckvieh calves, kept for two months (pre-weaning) in outdoor individual pen-and-shelter units, and observed at monthly intervals. During the study the calves' lying and moving behaviour in the shelters were separately observed and evaluated. The ambient temperature outdoors was also recorded. Statistically significant relationships between the calf’s season of birth, as well as the age of the calf and the evaluated forms of behaviour, were found. Outdoor ambient temperature was found to have a statistically significant effect on calf preference for standing or lying down. More standing calves than lying calves were recorded outdoors at higher outdoor ambient temperatures. Calves showed a clear preference for lying down, especially in the sheltered parts of the units (64.86%). Only 4.98% of the calves lay outside; 19.18% were standing outside, while 10.98% preferred standing inside the shelter. The calves lying down outside were significantly younger while older calves were lying inside the shelter.
在饲养系统中,犊牛行为是犊牛福利的重要指标,影响着奶牛的高效生产。在这项研究中,奶牛犊牛的行为模式在室外单独围栏和围栏单位进行了调查。该研究对683头西门塔尔-弗莱克维小牛进行了为期12个月的研究,在室外单独的围栏和围栏单元中饲养了两个月(断奶前),并按月间隔进行观察。在研究过程中,分别观察和评估了小牛犊在避难所的躺卧和移动行为。室外环境温度也被记录下来。研究发现,小牛的出生季节、年龄和被评估的行为形式之间存在统计学上显著的关系。室外环境温度对小牛站立或躺着的偏好有统计学上显著的影响。在室外较高的环境温度下,站着的小牛比躺着的小牛多。小鹿明显倾向于躺下,尤其是在有遮蔽的地方(64.86%)。只有4.98%的小牛躺在外面;19.18%的人选择站在户外,10.98%的人选择站在庇护所内。躺在外面的小牛明显更年轻,而年长的小牛则躺在棚子里。
