Barley ( Hordeum vulgare L.) is the third most important grain crop after wheat and maize in Europe, but the average annual increase in barley yield was 37 kg/ha during period of 1970-2020. The aim of the study was to evaluate the expression of yield potential of eight malt barley genotypes under agro-climatic conditions of the Danubian Hills region in southwestern Slovakia. The effect of season had a decisive share (62.7%) in the total variability of yields. The contrasting nature of the evaluated years is documented by the differences in yields of the set of evaluated varieties in an ascending order: 4.23 t/ha, 6.10 t/ha up to 8.17 t/ha during 2012-2013-2014.The effects of site and genotypes were evident, but with a relatively low contribution of 14.13% and 1.03% of site and genotypes, respectively, to the total variability in grain yield of barley, which indicate the relative consistency of the set of genotypes evaluated. The environmental index (EI) of yields confirmed the different environmental conditions manifested by the expression of yield potential ranging from 5.17 t/ha to 7.31 t/ha. The EI expression of yields for individual years and locations can be considered as an important indicator, indicating a better interpretation of the suitability of the locality for the cultivation of a given crop. The above conclusions reached from the experimental results support the need for more detailed data analysis of varieties to given agro-climatic conditions in order to select suitable genotypes for sustainable farming systems.
大麦(Hordeum vulgare L.)是欧洲继小麦和玉米之后的第三重要粮食作物,但在1970-2020年期间,大麦产量平均每年增加37公斤/公顷。本研究的目的是评价斯洛伐克西南部多瑙河丘陵地区农业气候条件下8种麦芽大麦基因型的产量潜力表达。季节的影响在产量的总变异中占有决定性的份额(62.7%)。评价年份的对比性质体现在各评价品种产量的差异上,产量的差异呈升序排列:2012-2013-2014年,产量为4.23 t/ha, 6.10 t/ha, 8.17 t/ha。位点和基因型对大麦籽粒产量总变异的贡献率相对较低,分别为14.13%和1.03%,表明所评价的基因型组具有相对一致性。产量环境指数(EI)反映了不同的环境条件,产量潜力表达式在5.17 ~ 7.31 t/ha之间。个别年份和地点产量的EI表达式可以被认为是一个重要的指标,表明更好地解释了该地区对种植特定作物的适宜性。从实验结果得出的上述结论支持需要对特定农业气候条件下的品种进行更详细的数据分析,以便为可持续农业系统选择合适的基因型。

Milk and dairy products are an important part of the human diet for numerous reasons. Goat milk is higher in the content of elements such as K and Ca. Nowadays, consumption of goat milk and goat dairy products increases because of better digestion and therapeutic value. However, goat milk can contain heavy metals and trace elements as well which can harm human health. The content of 22 elements in sixty-nine samples of goat milk, whey, three types of cheese, and yogurt from the ecological farm in region Orava and conventional farm in region Stredné Považie in Slovakia was measured in this study. The highest concentration of four elements Ca, K, Mg, and Na in samples of goat products was found. In our study, significant statistical differences ( P < 0.05) were found only in levels of K, Ca, Li and Na when comparing milk samples from organic and conventional farm. Concentrations of K (1260.50 mg/kg), Li (0.02 mg/kg) and Na (293.46 mg/kg) were higher in samples from ecological farm, while concentration of Ca (1344.65 mg/kg) was higher in samples from conventional farm. Toxic elements were present in trace amounts or under the limit of detection. The consumption of goat milk and goat dairy products from monitored farms can be considered as safe and beneficial for human health regardless of the way of farming. According to the highest level of strontium in hard ripening cheese, frequent regular consumption should be considered for children as a preventive measure for development of bone health.
牛奶和奶制品是人类饮食的重要组成部分,原因有很多。羊奶中钾和钙等元素的含量较高。如今,羊奶和山羊乳制品的消费量增加,因为它们具有更好的消化和治疗价值。然而,羊奶中也含有重金属和微量元素,对人体健康有害。本研究测定了斯洛伐克Orava地区生态农场和stredn Považie地区传统农场69份羊奶、乳清、三种奶酪和酸奶样品中22种元素的含量。山羊产品样品中Ca、K、Mg、Na四种元素含量最高。在我们的研究中,有机农场和常规农场的牛奶样品中只有K、Ca、Li和Na的含量有显著的统计学差异(P < 0.05)。生态农场样品中K (1260.50 mg/kg)、Li (0.02 mg/kg)和Na (293.46 mg/kg)浓度较高,常规农场样品中Ca (1344.65 mg/kg)浓度较高。有毒元素以微量或低于检测限度的形式存在。无论采用何种养殖方式,食用来自受监测农场的羊奶和山羊乳制品都可以被认为是安全和有益于人类健康的。根据硬熟奶酪中锶的最高含量,儿童应考虑经常食用,作为骨骼健康发展的预防措施。

The aim of the first experiment was to verify the effectiveness and profitability of providing supplemental feed to piglets. The milk feed mixture of two producers (MFM-1 vs MFM-2) were evaluated (served ad libitum ). All piglets were suckled and were fed with the pre-starter feed mixture from the 5th day until the weaning stage. The control group without milk supplements has shown a higher piglet mortality and worse body condition of sows. The usage of milk supplements led to the elimination of the sow body condition loss during the suckling period and reduced feed mixture consumption in sows ( P <0.05). The MFM-1 group was found to have a higher consumption of milk supplements, the lowest mortality and the lowest loss of sow body condition ( P <0.05). However, from the economic point of view, i.e. the costs on 1 weaned pig, slightly better results have been proven at the MFM-2 milk supplement. In the second experiment sows were divided into 2 groups. In the first group, the piglets were fed with milk substitute and in the second group, nurse sows (15% of the herd) were used. Nurse sows had a longer suckling period and farrowing interval, a slightly lower number of litters per sow per year and by 0.93 lower number weaning piglets per year. Using the milk substitute, generated a higher business profit per year than for nurse sows. However, the fact that nurse sows block the farrowing pen should be taken into account. In case that fewer sows were kept, business profit would be higher.
第一个试验的目的是验证向仔猪提供补充饲料的有效性和盈利能力。对两个生产者(MFM-1和MFM-2)的乳饲料混合物进行了评价(随意供应)。所有仔猪从第5天开始哺乳,饲喂预发酵剂混合饲料至断奶期。不添加牛奶的对照组仔猪死亡率更高,母猪身体状况更差。添加乳剂消除了哺乳期母猪体况损失,降低了母猪混合料消耗(P <0.05)。MFM-1组饲粮添加量较高,仔猪死亡率最低,母猪体况损失最低(P <0.05)。然而,从经济角度来看,即1头断奶猪的成本,已证明MFM-2补乳效果略好。试验2将母猪分为2组。第一组用代乳喂养,第二组用乳母(占母猪群的15%)喂养。哺乳母猪的哺乳期和产仔间隔较长,每头母猪每年产仔数略低,断奶仔猪数每年减少0.93头。使用牛奶替代品,每年产生的商业利润高于哺乳母猪。然而,应该考虑到护士母猪堵塞产房的事实。母猪存栏量越少,企业利润越高。

Legumes are a rich source of valuable nutrients thus represent important component in human and animal nutrition. The most important and often a limiting factor in legume production is the presence of seed pests, such as the bean weevil Acanthoscelides obtectus (Say, 1831). This work tested the suitability of three different legume species (common bean, faba bean and grass pea), the species with a growing interest in the human diet, for the development of the bean weevil, aiming to provide a reliable forecast of its population growth. After four months, been weevils consumed the highest percentage of the common bean kernels (70.79%), followed by the grass pea (53.13%), and faba bean (0.42%). The progeny production and population growth were significantly affected by the tested legume species. After each month, the total number of adults was the highest on the common bean, indicating its best suitability for the weevil’s development. Based on the number of the emerged specimens after each month of the observation, the bean weevil development was unhampered and continuous also on the grass pea. The lowest number of emerged adults, in all observation periods, was in faba bean, indicating its low preference and suitability for the weevil’s development. The population growth of the bean weevil was the highest on the common bean, followed by grass pea, and it fitted best to the quadratic equation model that enabled the prediction of the population growth of the bean weevil for each legume species in the next generations.
豆类是有价值的营养物质的丰富来源,是人类和动物营养的重要组成部分。豆科植物生产中最重要的、通常也是一个限制因素是种子害虫的存在,例如豆象甲Acanthoscelides obtectus (Say, 1831)。这项工作测试了三种不同的豆类物种(普通豆,蚕豆和草豆)对豆象虫发展的适应性,这些物种对人类的饮食越来越感兴趣,旨在为其人口增长提供可靠的预测。4个月后,象鼻虫对普通豆仁的摄取率最高(70.79%),其次是草豆(53.13%)和蚕豆(0.42%)。受试豆科植物对后代产量和种群增长有显著影响。每个月后,普通豆上的成虫总数最高,表明其最适合象鼻虫的发育。从观察后每个月出现的标本数量来看,豆象甲在豆荚上的发育也不受阻碍,而且是连续的。各观察期成虫羽化最少的是蚕豆,说明蚕豆对象鼻虫发育的偏好和适宜性较低。豆荚象鼻虫在普通豆上的种群增长最高,其次是草豆,并且最适合二次方程模型,该模型可以预测豆科植物各物种后代的豆荚象鼻虫种群增长。

The aim of this study was to determine the effect of organic leaf fertilization on the chemical composition, nutritive value, yield of crude protein (CP) and feed units of natural Agropyron repens grassland in the region of South-Central Bulgaria (305 m altitude). The experiment was carried out with leaf organic fertilizer Naturamin Plus, during the period 2018-2019. The trial was designed by the block method in 4 repetitions and 3 doses of fertilizer were tested: 1500; 2500 and 3500 ml/ha. The obtained results were statistically processed by ANOVA. The applied leaf organic fertilizer Naturamin Plus promoted a positive effect on the productive parameters of natural Agropyron repens grassland but had no significant effect on the chemical composition and nutritive value of the harvested biomass. The results demonstrated that yield of CP, feed units for milk (FUM) and feed units for growth (FUG) increased significantly by fertilization with a dose of 2500 ml/ha – respectively 22.2%, 29.7% and 29.4% more compared to the control.

The fortification of cassava leaves by adding nutrition is a recent technique in the ericulture study. Glycine is one of the amino acids necessary for the growth of silkworms. This study aimed to analyse the effect of glycine fortification of cassava leaves on the growth and development of eri silkworms. The parameters of this study were cocoon parameters, the wingspan of imago, development time and mortality, and egg parameters of Samia cynthia ricini D. This study had four treatments: control group, P1 group (adding glycine 0.5% on cassava leaves), P2 group (adding glycine 1% on cassava leaves), and P3 (adding glycine 1.5% on cassava leaves). The early instar of Eri silkworm larvae was fed on castor leaves, and glycine fortification was fed on the late instar of Eri silkworm larvae (fourth and fifth instars). Based on the results, all parameters showed significant differences from the control group. Glycine fortification increased cocoon weight (2.03 ± 0.62 g), extended the wingspan of the imago (12.15 ± 1.12 cm), shortened the development time (44.03 ± 0.84 days), had no mortality, and increased the fecundity of eggs (134.80 ± 28.78 eggs). The most effective concentration of glycine fortification on cassava leaves was 1.5%. Conclusively, cassava leaves with glycine fortification affect the growth and development of eri silkworm.
通过添加营养来强化木薯叶是农业研究中的一项新技术。甘氨酸是蚕生长所必需的氨基酸之一。本研究旨在分析木薯叶中添加甘氨酸对黑蚕生长发育的影响。本研究的实验参数为麻豆Samia ricini D.的茧参数、象翼展、发育时间、死亡率和卵参数。本研究设4个处理:对照组、P1组(在木薯叶上添加0.5%甘氨酸)、P2组(在木薯叶上添加1%甘氨酸)和P3组(在木薯叶上添加1.5%甘氨酸)。早期黑蚕幼虫饲喂蓖麻叶,后期黑蚕幼虫(4、5龄)饲喂甘氨酸强化饲料。结果显示,各参数均与对照组有显著差异。强化甘氨酸使茧重增加(2.03±0.62 g),翅展延长(12.15±1.12 cm),发育时间缩短(44.03±0.84 d),无死亡,卵繁殖力增加(134.80±28.78个)。木薯叶片上强化甘氨酸的最有效浓度为1.5%。综上所述,添加了甘氨酸的木薯叶片影响了家蚕的生长发育。

Glycine is one of the amino acids necessary for the growth of silkworms. This study aimed to analyse the effect of glycine fortification of cassava leaves on the growth and development of eri silkworms. The parameters of this study were cocoon parameters, the wingspan of imago, development time and mortality, and egg parameters of Samia cynthia ricini D. This study had four treatments: control group, P1 group (adding glycine 0.5% on cassava leaves), P2 group (adding glycine 1% on cassava leaves), and P3 (adding glycine 1.5% on cassava leaves). The early instar of Eri silkworm larvae was fed on castor leaves, and glycine fortification was fed on the late instar of Eri silkworm larvae (fourth and fifth instars). Based on the results, all parameters showed significant differences from the control group. Glycine fortification increased cocoon weight (2.03 ± 0.62 g), extended the wingspan of the imago (12.15 ± 1.12 cm), shortened the development time (44.03 ± 0.84 days), had no mortality, and increased the fecundity of eggs (134.80 ± 28.78 eggs).
