HighlightsTime to bind a round bale was longest for twine (56 s) compared to B-Wrap® (28 s) and net wrap (18 s).Alfalfa cultivar had minimal effects on changes in dry matter and forage quality of round bales stored outdoors.Dry matter losses were 7% for twine bales, 5% for net wrap bales, while B-Wrap® bales maintained DM in outdoor storage.Deleterious changes in forage quality were generally observed after =180 days of outdoor storage. Abstract. Large round bales are commonly fed to livestock; however, it has been well documented that outdoor storage can negatively impact dry matter (DM) and forage quality. To reduce storage losses and improve feeding value, new wrap types and alfalfa cultivars have been developed; however, these options have not been extensively investigated. Therefore, the objectives of this research were to evaluate the time required to bind large round bales, determine changes in DM and forage quality, and examine the economics of reduced-lignin and conventional alfalfa hay bound in twine, net wrap, and B-Wrap® while in outdoor storage. Hay was baled into 24 large round bales; 12 bales each of reduced-lignin and conventional alfalfa. Within each cultivar, four replicates were bound with each wrap type. Using stopwatches, the time to bind each bale was recorded. At the time of harvest, and every 90±3 days for 365 days, individual bales were weighed and cored to determine changes in DM and forage quality. Significance was set at P = 0.05. Time to bind a bale was longest for twine, intermediate for B-Wrap®, and shortest for net wrap (P < 0.01). Alfalfa cultivar had minimal effects on the parameters measured; therefore, the interaction between wrap type and storage length was reported. After 365 days in outdoor storage, DM losses were 7% for twine bales, 5% for net wrap bales, while B-Wrap® bales maintained DM. Changes in forage quality were observed at =180 days of storage where nonstructural carbohydrates were decreased and insoluble fiber components were concentrated. B-Wrap® bales had a higher value compared to net wrap and twines bales at 180 and 270 days in storage. These results suggest that B-Wrap® was better able to shed precipitation which preserved forage quality and bale value compared to large round bales bound in net wrap and twine in long term, outdoor storage.

Cereal and pasture hays, cut at the same site, were packaged into medium-sized round bales, large round bales and stacks. Halfthe number of each hay type and of each hay package were stored in the open for up to 15 months in a 500 mm rainfall area and half were transported to and stored for up to 15 months in a 1000 mm rainfall area. Densities of the pasture hay packages were within the manufacturers' specified ranges but those of the cereal hay packages were lower. Medium-sized round bales were less dense than large round bales and weathered more than large round bales and stacks after 10 and 15 months storage. Cereal hay packages deteriorated more than pasture hay packages with long-term storage. Medium-sized round bales lost more dry matter than large round bales after storage over the winter and more digestible dry matter over this period and after long-term storage. They also lost more crude protein than large round bales when stored over the first summer and over the following winter. It was economic to store all packages in the open over the first summer. It was uneconomic to store medium-sized round bales in the open over the following winter, while storage of large round bales and stacks was economic. For long-term storage, it was uneconomic to store any of the hay packages in the open, and storage under cover would have to be considered.

Harvest quality of sugar beet varies according to soil conditions, harvester type and setting, and variety, too. Harvest quality may affect storage losses, in particular when injuries occur. To determine the harvest quality of commercial sugar beet and to quantify resulting storage losses, 92 commercial sugar beet clamps were sampled across Germany and information about harvest conditions were gathered. At IfZ, soil tare, leaf residues, topping diameter, root tip breakage and surface damage of the beets were determined. The beets were stored in 6 replicates in a climate container at 9°C for 10 weeks. The results demonstrate a rather good harvesting quality of sugar beet in Germany. Soil moisture at harvest did not affect harvest quality and storage losses. Very light, but also heavier soils lead to inferior harvest quality (soil tare, root tip breakage, damage) and slightly higher storage losses compared to the typical loam soils. Significant differences occurred between the three harvester types (companies). In general, high root tip breakage and severe surface damage of the beet was related to a high infestation with mould and rots, high invert sugar contents after storage and high sugar losses. Out of the five most planted varieties, in particular one turned out to be very susceptible to damage, resulting in high storage losses. The factor analysis suggests that the effect of harvester / harvester setting and of variety is more important for harvest quality and storage losses of sugar beet than soil conditions at harvest. Therefore, attention should be paid to optimize these conditions.

No significant studies have yet been reported in Central Europe on the yield and quality of winter harvest pastures. The aim of the research was to collect information about the effect of pre-utilisation (June, July and August) and winter harvest date (November, December, January) on the quantity and quality of fodder from Festuca arundinacea stands. The dry matter, energy, ADF, ADL and ergosterol contents of the yield were examined and it was found that: 1. A shorter regeneration period between harvests resulted in lower dry matter levels, but also in a higher energy concentration and lower ergosterol concentration. 2. The yield and energy concentrations decreased, whereas the ADF, ADL and ergosterol concentrations increased as the winter progressed. 3. Fodder harvested in November produced the best results in terms of yield quantity and quality. The highest yield and energy values were thus achieved by harvesting in November, regardless of pre-utilisation. Despite the cold and the long period of snow cover, the energy values of samples harvested in December and January showed no significant decrease. The weather conditions were more important for fodder quantity and quality than the frequency or date of harvesting. Thus, under the continental climatic conditions in Hungary, extensive utilisation, until late November or early December, is recommended.

Studies with beef cattle (Kennedy and Carson, 1991) and dairy cattle (Chamberlain et al, 1990) have shown responses in dry matter intake of silage and animal performance through applying Maxgrass silage additive to unwilted herbage ensiled in clamps. Maxgrass (BP Chemicals Ltd) contains (weight/volume) 68% ammonium hexamethanoate, 11% ammonium hexapropanoate and 2% octanoic acid.Research at Aberdeen has shown the benefits of using both inoculant (Weddell, 1990a) and formic acid based (Weddell, 1990b) additives on big bale silage which now constitutes around 15% of the total silage dry matter ensiled in the UK. The present study compared the effects on silage composition, animal performance and storage losses of Maxgrass treated with untreated big bale silage.Second cut perennial ryegrass herbage was wilted to a mean DM content of 230 g/kg then baled by fixed chamber baler. Mean water soluble carbohydrate was 100 g/kg DM. Alternate groups of six bales were left untreated or treated with Maxgrass silage additive at 7.4 1/tonne wilted grass.

Wilting grass before ensiling has become a firmly established practice, since it provides economic advantages due to the increment of the dry matter content of the forage before ensiling. Most forage crops contain less than 20 per cent of dry matter when they are cut thus reduction of the weight of crop to be transported provides advantages (Gordon et al., 1999). Also, research has shown that such practices yield improved and reduced effluent loss from the silo and higher feeding value of the silage. Wilting of grass prior to ensiling has been widely adopted as a means of reducing effluents produced and improving the fermentation quality of silage. The aim of this research was to assess the effect of differing wilting periods and silage moisture levels of silage quality and microbial growth levels.

Studies on the frozen storage of human blood products have benefited veterinary transfusion medicine in recent years, but the long-term cryopreservation of canine red blood cells (RBCs) has not yet been thoroughly investigated. Further, no studies are available with respect to the frozen storage of leukocyte-depleted canine red blood cells (LD-RBCs). The objective of the current study was to investigate time-dependent effects of long-term frozen storage on leukocyte-depleted canine RBCs. Twelve healthy adult dogs meeting the criteria for blood transfusion were used in the study. Whole blood samples (450 ± 45 ml) collected from each dog were centrifuged for 5 min at 22 °C and 4200 × g in a cryogenic microcentrifuge and concentrated RBC (pRBC) suspensions were obtained. Leukocyte depletion was achieved by filtration (2.6 log<sub>10</sub>). Then, the filtrated samples were prewashed three times in 0.9% NaCl solution and were allocated into three subgroups to be evaluated at three different time points (Day 0, Month 4 and Month 6). The samples for cryopreservation were subjected to glycerolisation and then stored at –80 °C for 4- and 6-month periods. At the end of this period pRBC units were thawed by manual agitation in a water bath maintained at 36–38 °C, centrifuged and then washed in a consecutive series of 12%, 1.6% and 0.9% of NaCl + 0.2 dextrose solutions. 2,3-Diphosphoglycerate (2,3-DPG), adenosine triphosphate (ATP), supernatant haemoglobin (SupHb), sodium (Na<sup>+</sup>) and potassium (K<sup>+</sup>) levels, residual glycerol concentrations and haemograms of thawed and deglycerolised pRBC samples were evaluated together with those of Day 0. Sterility tests were performed on all samples for bacterial contamination. No statistically significant differences were noted except for Hct and SupHb levels. No bacterial contamination was noted in any of the samples on the basis of sterility tests. It was found that the described glycerolisation procedure could be a method of choice in the cryopreservation of leukocyte-depleted pRBCs (LD-pRBCs) since no negative effect was observed on the quality of the products and long-term frozen storage did not cause RBC destruction.

SUMMARYPost-anthesis trends in yield and forage quality of dry matter in components of the maize shoot were studied in experiments with barren and fertile plants grown at 10 plants/m2. In fertile plants, which had a maximum shoot DW 6 or 7% higher than barren ones, the stems (including leaf sheaths) yielded 5 t/ha (42% shoot DW) 30 days after flowering, declining to 3·5 t/ha (26% DW) at final harvest 60 days later. During this period the ear increased by more than 4 t/ha, from 23 to 50% of shoot DW, whereas in barren plants there was little change in DM distribution, with the stem representing about 48% shoot DW, leaf and husk together 40–45% and the ear (rachis only) less than 10%. DM percentage of shoots was similar in barren and fertile plants until maximum DW was attained about 60 days after flowering, after which fertile plants dried more rapidly. In vitro dry matter digestibility was as high in barren as in fertile plants, and the analytical data on forage quality do not suggest that it was positively associated with grain content.

The biobank is a structure established with the goal of long-term responsible storage of biological samples and the associated data for their further use in scientific and clinical research. The objectives of biobanking are the creation of unified recommendations on: the planning of premises and the selection of equipment for storage; development of management methods and staff training; standardization of methods for the collection, shipping, processing and storage of biomaterial of various origins, as well as methods for quality control and validation of the applied methods; creation and use of databases of information accompanying biospecimens. The lack of common standards for conducting the preanalytical phase has been the cause of low accuracy and poor reproducibility of research results. To date, a large number of guidelines and best practices have been published that provide an answer to a wide range of problems in organizing the biobanking process. The article provides an overview of the most famous biobanking guidelines that can be used to solve various research problems. Biobanking in Russia is actively developing. Since 1996 there is a work on the legislative regulation of biobanking activities, as a result of which a number of regulatory documents have been issued. An important stage in the development of biobanking in Russia was the establishment of the “National Association of Biobanks and Biobanking Specialists” (NASBio) in 2018, which included representatives of medical and research institutions, commercial firms, and qualified specialists in the field of biobanking. One of the key tasks of NASBio is the adaptation and implementation of the best biobanking practices in Russian research institutes and centers. The use of modern guidelines and best practices on biobanking will lead to an increase in the quality of research and publications.
