Here, the specific natural variability of iPBS (Inter Primer Binding Sites Polymorphism) fingerprints in thirteen varieties of Vitis vinifera , L. was performed. All of the analysed biological material was collected in the vineyard of Sabo vinery for describing of the existing genetic polymorphism. Young leaves from a total of thirteen grapevine varieties were obtained in the in the Small Carpathians wine region of Slovakia, Vrbové. Genetic length polymorphism was studied by iPBS markers. A dendrogram of genetic similarity of generated fingerprints was constucted by UPGMA (Unweighted Pair Group Method with Arithmetic mean) and the Jaccard coefficient of genetic similarity was used for the analyse of 13 Vitis vinifera , L varieties. The generated dendrogram is separated into three major clusters at the genetic dissimilarity of 0.58. Cluster 1 is composed of two red varieties – Alibernet and Cabernet Sauvignon. Cluster 2 was further subdivided into two sub-clusters, where the larger one include all white varieties – Pinot Blanc, Müller-Thurgau, Welschriesling, Irsai Oliver, Grüner Veltliner, Pálava, Weisser Riesling, Sauvignon Blanc and Feteasca Regala. The second subcluster is comprised from two red varieties – Blaufränkisch and Dornfelder. The analysis prooved the the iPBS technique is an effective retrotransposon based markers to evaluate the variability of the genome in the germplasm of Vitis vinifera L. cultivated varieties.
本文对13个葡萄品种的iPBS (Inter Primer Binding Sites Polymorphism，引物结合位点多态性)指纹图谱进行了特异性自然变异分析。所有分析的生物材料都是在萨博葡萄园收集的，用于描述现有的遗传多态性。在斯洛伐克的小喀尔巴阡山脉葡萄酒产区vrbov获得了13种葡萄品种的嫩叶。利用iPBS标记分析遗传长度多态性。采用UPGMA (Unweighted Pair Group with Arithmetic mean)方法构建了指纹图谱的遗传相似度树图，并采用Jaccard遗传相似系数对13个葡萄品种进行了遗传相似度分析。生成的树状图在遗传不相似度为0.58时分为三个主要簇。集群1由两个红色品种组成——艾丽伯内和赤霞珠。集群2进一步细分为两个子集群，其中较大的集群包括所有白葡萄酒品种-白皮诺，梅勒-图尔高，Welschriesling, Irsai Oliver, grisser Veltliner, Pálava, Weisser Riesling，长相思和Feteasca Regala。第二个子簇由两个红色品种组成- Blaufränkisch和Dornfelder。结果表明，iPBS技术是一种有效的基于反转录转座子的葡萄栽培品种种质资源基因组变异评价方法。

The present investigation was carried out to study the influence of planting date and field management practices on bulb quality and post-harvest losses of onions in storage at Agriculture Research Farm of Kabul University. Different traits including fresh bulb weight, total soluble solids, firmness, rooting, sprouting, spoilage and marketable bulbs were studied in these trials. The data were statistically analysed with R software. The planting dates had significant effect on fresh bulb weight, sprouting, spoilage and marketable bulbs of onions. After 120 days of storage the greatest fresh bulb weight (111.64 g), marketable bulbs (77.52%) and the lowest sprouting (10.56%) and spoilage (11.92%) were recorded for the first planting date (10 th May). Similarly, the lowest loss in total soluble solids was also observed under the first planting date. Field management practices did not have significant effect on bulb quality and post-harvest losses of onions. While delayed planting can significantly reduce onion bulb quality and increase sprouting and spoilage, early planting dates were more appropriate to reduce post-harvest losses.

The stable fly, Stomoxys calcitrans , is the most important ectoparasite of livestock throughout the world. Entomopathogenic fungi are natural antagonists of stable flies with the potential to be used as biocontrol agents in integrated management programmes of this pest. The prevalence and species diversity of entomopathogenic fungi in stable fly populations were documented on a dairy cattle farm in south-western Slovakia. The prevalence of fungal infection was low and the maximum percentage of infected flies reached 2.72% during May–October in 2016. Three Beauveria species were identified from infected flies, B. bassiana , B. pseudobassiana and B. brongniartii . Beauveria pseudobassiana and B. brongniartii are reported from S. calcitrans for the first time. In laboratory tests, the pathogenicity of four entomopathogenic fungi B. bassiana , B. pseudobassiana , M. anisopliae and Isaria fumosorosea against adult stable flies was compared. The flies were susceptible to infection by the fungi and the most virulent isolate of B. bassiana (IKEP10) was selected for spore formulation testing and field trials. We tested three types of spore formulations and the aqueous spore suspension was more effective against stable flies than spores formulated in the powder or oil suspension. Repeated treatments of the interior of the stable with B. bassiana spores at fortnightly intervals during June–August resulted in a 10 times higher prevalence of fungal infection in the stable fly population compared with the untreated stable, but the treatments did not effectively reduce the fly population. The selected B. bassiana isolate may represent an interesting tool in the biocontrol of stable fly populations, but further experiments are needed to design an appropriate formulation and enhance its efficacy.

The fungus Cercospora beticola Sacc. belongs to the most important pathogens on sugar beet. The Cercospora leaf spot disease is important problem for growers in all growing areas of sugar beet. This study was focused on the morphological diversity of C. beticola isolates and occurrence of their fungicidal resistance in Slovakia. Isolates involved in this work were collected from sugar beet leaf during 2016–2018. Average growth rate of the tested C. beticola isolates on five different media showed the major role of cultivation temperature. The fastest growth was measured by 30 °C on TE medium, followed by PDA, SBLEA, AWSBL, and V8. The colour of aerial mycelium varied from olive-green to grey with white powdery appearance, per grey colour with wrinkled texture, to black colour. There is no significant correlation among isolates origin, colony morphology parameters and growth rate. The highest sporulation rate was recorded at cultivation temperature 25 °C by using of TE growth medium, the lowest one by V8 medium. The inhibition effect of azoxystrobin + cyproconazole was significantly different among the tested isolates from different localities and years. The results showed reduced sensitivity of C. beticola population in Slovakia strictly depending of the locality. The most reduced sensitivity was measured on localities Hronovce and Nové Zámky, followed by localities Mojmírovce, Senec, and Dolné Saliby with similar values. There is no positive correlation between inhibition effect and mycelial growth rate. The results showed increasing fungicidal resistance of C. beticola to azoxystrobin + cyproconazole in some localities of Slovakia.

Developments in sequencing and SNP chip technologies have enabled scientists to obtain high-density genomic data from different livestock species, including cattle. Moreover, many bioinformatics tools are available to analyse high-density genomic data. Via these tools, several statistical approaches such as Principal Component Analysis and clusterin-based analyses could be conducted to reveal the genetic structure of cattle populations. However, revealing the genetic structure and selection signatures of Turkish cattle breeds is a new area of research, since the previous studies are limited with a few microsatellite data. On the other hand, rearing in different geographical and environmental conditions for a long period could possibly lead to more genetic variation in native Turkish cattle breeds compared to high-yielding culture breeds. These variations obviously cannot be detected by limited number of microsatellite markers, while Next Generation Sequencing is promising for further population structure studies. Hence this review aims to summarise previous studies and give a perspective of Next Generation Sequencing possibilities to reveal the population structure of Turkish cattle for further studies.

a In industrial complexes, the environment for fattening pigs has limited space and often does not respect natural behaviour of pigs. The implementation of EU legislation in Ukraine requires from farmers to use enrichment materials that improve the welfare of pigs. This article shows possible solution for big industrial challenge – creating of comfortable conditions for pigs, which meet their ethological needs. The experiment was performed on 180 pigs. From 77 days of age, all experimental animals were divided into three groups (on the principle of analogues) of 60 heads in each. As criteria of aggressive social behaviour the fights and biting were chosen. It was found that at the first period of fattening in pigs of the control group (no enrichment materials) 24 cases of biting were registered, in animals with straw blocks (experimental group II) – 6, with plastic bottles filled with grain (experimental group III) – 4 cases. At the second period of fattening, the situation regarding intragroup aggression was identical to the first one, which was reflected by the level of the cortisol in the blood serum. Among pigs that had free access to enrichment materials, a significant increase in their live weight by 2.4–5.8%, and in average daily gain by 1.4–27.6% compared with animals in the control group was registered. This study aims to prove that the use of enrichment materials for fattening pigs helps to identify their natural behaviour in industrial complexes, avoids social aggression, increases productivity and improves their welfare .

Clinical mastitis is an inflammatory disease of the mammary gland that largely impacts dairy farming profitability and welfare. Globally, a massive scientific effort is being made to elucidate the possible link of certain genotypes to the susceptibility to this disease. After data pruning controlling for genotype missingness, minor allele frequency, and population stratification, 51 557 SNPs from 1 042 animals have been analysed using the general linear model (GLM). Two SNPs, BTA-121769-no-rs and BTB-00265951, have demonstrated statistically significant associations (-log 10 ( p ) >6.0134), both located on the chromosome BTA6. The detected SNPs have been annotated within a reference genome. They have been found to lie outside of transcribed regions but within the vicinity of genes essential for the immune response. This finding further supports the case for their significance in the resistance to mastitis. In addition, 14 relatively weaker associations (-log 10 ( p ) >4) have been observed across chromosomes BTA1, 2, 9, 14, 19, 24 and 25.

It was published, that grape pomace has a positive effect on the animal organism and is also a rich source of fatty acids. The inclusion of grape pomace in the geese feed mixture was the main objective of the following experiment. The addition of grape pomace into the feed mixture was used to investigate to what extent will affect the fattening parameters of geese and the profile of fatty acids analysed from the abdominal fat of geese. The experiment was carried out on 20 geese (Czech goose breed). Two groups were formed to obtain the same average weight. The average weight of the experimental group at the beginning was 1857 ±196 g. The average weight of the control group was 1872 ±248 g. For 49 days, both groups were fed a commercial complete feed mixture for geese fattening while in the experimental group 1% of the feed mixture was replaced by dried grape pomace. The average weight of geese of the control group at the end of fattening was 5579 ±770 g and of the experimental group 5752 ±752 g. The addition of dried grape pomace to the feed mixture in the fattening of geese increased the average daily weight gain of geese by 5.2% ( P ˃ 0.05), liver weight by 22.5% ( P <0.05) and increased the content of monounsaturated fatty acids by 2.5% ( P >0.05), especially oleic acid by 3.0% ( P >0.05). A reduced content of polyunsaturated fatty acids by 1.5% ( P >0.05) and decreased saturated fatty acid content by 3.2% ( P >0.05) was detected in the experimental group. It can be concluded that the addition of grape pomace affected the liver weight of fattened gees, while the effect on fatty acids composition was insignificant.

The addition of dried grape pomace to the feed mixture in the fattening of geese increased the average daily weight gain of geese by 5.2% ( P ˃ 0.05), liver weight by 22.5% ( P <0.05) and increased the content of monounsaturated fatty acids by 2.5% ( P >0.05), especially oleic acid by 3.0% ( P >0.05). A reduced content of polyunsaturated fatty acids by 1.5% ( P >0.05) and decreased saturated fatty acid content by 3.2% ( P >0.05) was detected in the experimental group. It can be concluded that the addition of grape pomace affected the liver weight of fattened gees, while the effect on fatty acids composition was insignificant.","PeriodicalId":7312,"journal":{"name":"Acta Fytotechnica et Zootechnica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49530292","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}
