Design, construction and field testing of a manually feeding semiautomatic sugarcane dud chipper

Sugarcane is the main sugar crop, and sugar is an important agricultural product in Egypt. There are many problems with the technology used in the current planting method of sugarcane, which has a great impact on the planting quality of sugarcane, which have a series of problems, such as low cutting efficiency and poor quality. Therefore, the aim of the current study was to design, construct, and field testing of a semiautomatic sugarcane bud chipper assisted with pivot knives for cutting sugarcane buds and germinating them in plastic trays inside a greenhouse until they reached an average length of 35 cm, and then planting them in the field. In the field tests five cutting speeds (35, 40, 45, 50, and 56 rpm. (Revolution Per minute), three cutting knives (1.5, 2.0, and 2.5 mm) were used for cutting sugarcane stalks with four different diameters (1.32, 1.82, 2.43, and 2.68 cm). The obtained results showed that the values of the damage index and invisible losses were within acceptable limits (ranging between − 1.0 and 0.0) for all the variables under the test. Still, the lowest damage index and invisible losses were recorded with the buds that were cut with a knife of 1.5 mm thickness and cutting speeds less than 50 rpm. The skipping rate increases with the increase in cutting speed and stalk diameter, ranging between 0.0 to 13%. The maximum machine productivity was 110 Buds per minute at a cutting speed of 35 rpm and stalk diameter of 1.32 cm. The paper's findings have important application values for promoting the designing and development of sugarcane bud chipper and sugarcane planting technology in the future.

"Failed" Matches, Child Removals, and Disrupted Placements: Devastating and Invisible Losses During the Family-Building Journey for LGBTQ Adoptive Parents.

Reproductive loss, which includes miscarriage and nongestational loss, such as adoption loss, is rarely recognized as part of the family-building journey. Such loss tends to be even more invisible among LGBTQ individuals. The current study examines the experiences of 80 LGBTQ individuals who experienced adoption-related losses (i.e., failed adoption matches, child removals, disrupted child placements), with attention to how these losses impacted them and what enabled them to move forward. Participants who pursued private domestic adoption experienced failed matches (i.e., birth parents deciding to parent or choosing another family) both before (n = 21) and/or after (n = 24) a child was born. Participants who pursued public domestic adoption experienced child removals involving reunification with birth parents (n = 14) and other birth relatives (n = 18), as well as disrupted placements initiated by parents (n = 10) and children (n = 7). Failed matches, child removals, and disrupted placements were typically experienced as "crushing" and invisible losses. They were often followed by a period of grieving, and sometimes prompted adjustments to the type of matches or placements participants would consider (e.g., to mitigate the likelihood of future similar losses). Moving forward from adoption losses was facilitated by support from partners and those who experienced similar losses, knowledge or hope regarding the children once in their care, and finally being placed with the child(ren) whom they ultimately legally adopted.

CONTINUOUS AND IMPACT CUTTING SYSTEMS FOR SUGARCANE HARVESTER

The quality of the basal cut of sugarcane during harvest can affect the longevity of the crop, and the cutting tool is one of the main causes of damage during harvesting. The aim of this study was to evaluate the performance of two cutting tools: an impact cutting system (ICS) using knives and a continuous cutting system (CCS) using saws. Laboratory tests were carried out to obtain the stalk damage index at different device travel speeds and to determine the invisible losses caused by each cutting system. The results showed that both cutting systems presented acceptable levels for the stalk damage index; however, the CCS obtained better cut quality, corresponding with decreased general damage. The invisible losses caused by the cutting tools in relation to the total harvested mass were 0.52% and 0.54% for the CCS and ICS, respectively. The highest invisible losses were obtained at speeds of 2, 3, and 4 km h-1 for the ICS, showing a statistical difference in relation to the CCS. No statistical difference was noted for both the systems at 5 and 6 km h-1.

Effect of acid based additive treatment of low dry matter grass crops on losses and silage quality in bunker silos

The large surface area of bunker silos imposes challenges with heating caused by plant respiration during initial ensiling. This study aimed to explore if application of a formic- and propionic acid-based additive would improve grass silage quality, reduce losses, and increase aerobic stability in bunker silos. At each of three harvests, every second tractor load was filled with either untreated or acid treated precision chopped crop, and ensiled in each of two identical bunker silos, 6 m × 27 m with three 3.5 m high walls, without roof. Each load in both bunker silos was compacted by two packing machines. Initially, an 8.3 t farm tractor worked for 10 min. followed by a 14.5 t wheel loader for 10 min. Silos were filled to approximately half of their capacity.Due to showers during all three harvests, crop dry matter (DM) concentrations were only 195, 186 and 213 g/kg, respectively. During unloading for feeding, silage DM density and DM concentrations were respectively 7% and 5% higher (P < 0.01) in acid treated (A) than in control (C) silage. This was presumably due to early cell rupture caused by the applied acid, and thereby higher effluent release from A than C silage. Additive treatment did not influence the amount of wasted silage. Invisible losses, that included crop respiration, effluent runoff, anaerobic fermentation, aerobic deterioration from the silo face, and gaseous losses were numerically higher in A than C silos on fresh weight basis, but slightly lower on DM basis. The proportion of harvested crop DM that was offered to animals was 837 and 829 g/kg for A and C silage, respectively (NS).Additive treatment reduced the proportion of non-protein N in total N, restricted silage fermentation to lactic and acetic acid, reduced NH3-N-values, and increased ethanol fermentation (P < 0.01). Silage DM intake index was higher for A than C silage (P < 0.001). Aerobic stability was not significantly influenced by additive treatment. The concentration of spores of Clostridium tyrobutyricum in spot silage samples from bunker silo faces was low or moderate, and did not differ according to additive treatment. Silo shoulder and side samples contained, however, significantly higher spore concentrations than mid and top samples.

Optimization of Conventional Combine Harvester to Reduce Combine Losses for Basmati Rice (&amp;lt;i&amp;gt;Oryza Sativa&amp;lt;/i&amp;gt;)

A study was conducted at PAU Regional Research Station, Gurdaspur (Punjab) to investigate the design and operational parameters of threshing mechanism of conventional combine harvester for basmati crop. This study was aimed to investigate the suitable changes required in the self-propelled conventional combine harvester for harvesting the basmati crop with minimum grain losses. Field evaluation of experiment was carried out to assess the influence of independent design variable i.e., arrangement of spikes (AS) and independent operational parameters such as concave clearance (CC) and cylinder speed (CS). The study was aimed to enumerate various combining losses viz., extent of visible and invisible grain damage and threshing efficiency at different AS, CC and CS levels. The first year data recorded during 2017 were processed for the optimization during 2018. The results of the present study revealed that during 2017, maximum visible and invisible losses was 5.49% ± 0.33% and 28.07% ± 3.21%, respectively whereas after modification, these losses remained only 4.00% ± 0.80% and 24.07% ± 2.86%, respectively. The threshing efficiency remained above 99.31% ± 0.47%, for both years. Thus, optimization of combine harvester was able to save the visible grain damage by 60% to 83% and invisible grain damage by 6% to 16%, respectively during 2018 than the year 2017.

Applying intersectionality to climate hazards: a theoretically informed study of wildfire in northern Saskatchewan

ABSTRACT Impacts and losses as a result of climate hazards are experienced unevenly across communities and can prove devastating to the health and well-being of local residents. Contextual approaches for understanding vulnerability and adaptation have focused on why diverse individuals and groups experience the effects of climate change differently, while values-based approaches place emphasis on identifying the subjective values individuals and communities wish to preserve. Both approaches contribute to locally responsive adaptation, but are rarely applied simultaneously. In this paper, we propose intersectionality as a framework that links and builds upon contextual and values-based approaches and demonstrate its efficacy through an empirical example of a major wildfire event in northern Saskatchewan, Canada. An intersectional framework identified how impacts and losses to locally significant values differed across intersections of location, race, ethnicity, gender and age and how these differences were influenced by broader social structures and power relationships, such as histories of colonization and gendered norms and expectations. Practical implications for the development of inclusive and equitable adaptation policy and planning were also identified, including the need to: (a) expand the range of impacts considered and recognize how outcomes differ across social groups; (b) enhance diverse community members’ participation in planning efforts, and (c) acknowledge and build upon what local residents are already doing in response to hazards in their communities. Key policy insights Failure to consider how impacts and invisible losses are experienced across intersections of identity can lead to adaptation policy and practice that reinforce existing social inequalities. An intersectional analysis revealed a suite of context-specific, locally-relevant values and systems of power that shaped how communities experience, respond to, and plan for climate hazards. The application of an intersectional framework can provide practical direction for adaptation policy that: (1) responds to differing experiences and values across social groups; (2) recognizes agency and builds on what people are already doing; and, (3) addresses root causes of vulnerability.

Losses and grass silage quality in bunker silos compacted by tractor versus wheel loader

The study aimed to explore whether an increase in bunker silage density obtained by turning to a heavier packing machine than a farm size tractor would reduce losses and improve grass silage quality and aerobic stability. At each of three harvests, two bunkers were packed with either a 14.5 t wheel loader (WL) or an 8.3 t tractor (T). For comparison with the bunker silages, silage was produced simultaneously in round bales with high and low chamber pressure and wrapped immediately or after delay, and in laboratory silos.Compaction with WL increased silage dry matter (DM) density by 9 % compared with T, from 204 to 222 kg DM/m3. On average for three harvests, DM recovered as silage, or lost, was almost identical for the two packing treatments, with 870 g/kg of harvested DM recovered as feed offered to animals, 55 g/kg as wasted silage, and 75 g/kg as invisible losses due to respiration, effluent, fermentation and aerobic deterioration. However, in the harvest with lowest crop DM content, 266 g/kg, invisible DM losses with WL exceeded losses with T by 46 g/kg, of which the main portion was assumed to be caused by more effluent squeezed out by the WL. In the harvest with highest crop DM, 332 g/kg, invisible DM losses with T exceeded losses with WL by 43 g/kg, of which the main portion was assumed to be caused by poorer compaction with T, and therefore higher respiration and aerobic deterioration losses. Wasted silage DM was lower in bales than in bunkers (P = 0.004). The proportion of offered silage DM from poorly compacted bales sealed after delay (867 g/kg) was similar to that of bunkers, whereas the proportion of offered silage DM from well compacted and immediately sealed bales (963 g/kg) was similar to that of laboratory silos.Significant increases in protein bound in the neutral detergent and acid detergent fiber fractions were found in bales sealed after delay where temperatures had rised to 47 °C at wrapping. Similar levels of fiber bound protein were found in bunker silage, suggesting that they were also heated during filling. Spot samples from bunker silo shoulders were more infected by yeasts, moulds and Clostridium tyrobutyricum than samples from mid in bunkers and from bales. No differences in losses, silage composition or aerobic stability were observed between bunker silo packing with WL or T on average over three harvests.

Invisible losses. What a catastrophe does to forest owners’ identity and trust in afforestation programmes

AbstractIn Ireland the political consensus to expand forest cover has not been really questioned for the last five decades, neither by policy‐makers nor by forest owners’ representatives. However, in 2014, Irish private forest owners experienced for the first time in their life a catastrophic windstorm. A qualitative survey, conducted among the forest owners affected by the storm, shows that beyond the economic losses this disaster deeply shook their convictions about the real benefits of afforestation programmes. Using the theoretical concept of relational expectations, we show that Storm Darwin deconstructed a significant part of their identity as their status switched from audacious pioneer to forestry loser overnight. The political and socio‐economic structures outweighed the agency of individuals and their initial desire not to reforest. While the reconstitution scheme gave them the direction to follow, it reduced the risk of desertion. However, our study also shows that landowners may be a lot more cautious before signing up for afforestation programmes in the future.

Quality of mechanical peanut sowing and digging using autopilot

ABSTRACT Over the past decade, automatic guidance of agricultural machinery via Global Navigation Satellite System (GNSS) signals has been increasingly adopted by the farming community. Peanut farmers are adopting such technology in order to improve the parallelism of operations to address difficulties that occur in mechanical digging, where losses are a big problem. This study aimed to evaluate mechanized operations of peanut sowing and digging controlled manually and by autopilot, along with their quality. The treatments consisted of two digging operations, with and without autopilot, and two displacement speeds (4.5 and 6.0 km h-1). The experiment was conducted in a medium-textured soil in a completely randomized design arranged in bands, using the analyzed variables as quality indicators. At sowing, parallelism between passes of the tractor-sower set, was evaluated at 120 points of each system (manual and automatic routing). The digging losses were evaluated in the two guidance systems, under two displacement speeds (4.5 to 6.0 km h-1) at 15 points per treatment. It was verified that the parallelism between the passes of the tractor-sower set was better when using the autopilot, which improved the operation quality. Displacement speed did not influence the digging loss. There were no differences in the visible digging loss, but higher quality was obtained when the operation was performed using autopilot. Minor invisible and total digging losses were obtained when the digging was performed with automatic routing, and superior quality was found at a speed of 4.5 km h-1; however, quality was adversely affected under manual operation. Thus, the use of autopilot is effective for improving the accuracy and the quality of the operations.

Perdas na colheita mecanizada da cana-de-açúcar em resposta a diferentes velocidades da colhedora e de rotação do extrator primário

The present study aimed to evaluate the visible and invisible losses in mechanized harvesting of sugarcane by using different speeds of the harvester's displacement and rotation of the primary extractor in first-cut cane fields with 7% slope. The trial was conducted in June 2014, at the time of mechanical harvesting in first-crop cane (cane of year), with a productivity estimate of 75 t ha-1 in the city of Pacaembu, Sao Paulo. The sugarcane was formed by the variety RB96-5902, with 12 months of age, in spacing of 1.4 meters between rows. Harvesting was performed using a John Deere harvester, model 3520 accompanied by a tractor, coupled to the transhipment. The treatments evaluated correspond to combinations of two speeds of displacement of the harvester (km h-1) and two speeds of rotation of the primary extractor (rpm), in addition to the speeds usually used by the plant as a control: 3 km h-1 at 700 rpm , 3 km h-1 at 1200 rpm, 5 km h-1 at 950 rpm (control), 6 km h-1 at 700 rpm and 6 km h-1 at 1200 rpm. The analyzed variables were the losses in the forms of stumps, bluffs, toletes, pieces, whole reeds, shards and total losses, in t ha-1 and the total percentage of losses. Significant responses (p ≤ 0.05) were observed for all forms of losses as a function of treatments, except for losses in whole cane and shoot forms. It was concluded that the increase of the rotation of the primary extractor and reduction in the speed of locomotion of the harvester tend to cause an increase in the losses of sugarcane, being, in the conditions of the present study, indicated the speed of 3 km h-1 with rotation of the primary extractor of 1200 rpm.

People, place, and animals: using disemplacement to identify invisible losses of conservation near Limpopo National Park

Conservation has the potential to negatively impact nearby communities through readily measurable losses, like economic livelihoods, and those less tangible, like cultural identity and a sense of place-based heritage. In this paper, I analyze interviews with residents living in the border zone of Mozambique’s Limpopo National Park to identify the invisible losses of conservation. Using disemplacement as a critical lens, I illustrate how conservation disrupts the person–place bond that forms between people and the environment they inhabit. Using disemplacement, this paper shows one method to improve our ability to capture, understand, and respond to the invisible losses of conservation.

Within the context of precision agriculture, the use of automatic guidance is without a doubt one of the most popular tools among farmers, however, are few producers of peanuts using this technology, the benefits from this technology can bring significant gains for culture even more when thinking about reducing the indices of losses in the digging. Thus, it objective was to evaluate the variability of quantitative losses of peanut mechanized digging with use the autopilot, using the Statistical Process Control. The treatments consisted of absence of autopilot use in sowing and digging, pilot&#39;s absence at sowing and presence in the digging, pilot use at sowing and absence in the digging and the pilot use in sowing and digging. In each treatment, 15 points of each variable was collected from distance of 50 m apart. Visible, invisible and total losses in the digging and parallelism were evaluated. The reduction of the plant material on the vibratory mat affected the levels of visible losses. Total losses are strongly correlated with the invisible losses. The use of the autopilot allows the operator to pay more attention to the digging operation improving the quality of the operation. The average error found between passes of the mechanized set using autopilot was 0.35 m. The variability of the losses as well as of parallelism was reduced when using the autopilot in two operations, providing a higher quality process. &nbsp; Key words: RTK (Real Time Kinematic), automatic guidance, precision agriculture, statistical process control.

Considering that mechanized digging is an important stage in the productive chain of peanut, the studies related to the quantification of visible, invisible and total losses are still scarce, making it necessary to investigate these losses in order to obtain the operation control. In this context, the aim of this study was to evaluate the losses mentioned and the operational performance in the mechanized peanut digging related with five rotations in the tractor power take-off (PTO), verified by statistical control of the process (SCP). The experiment was carried out in tracks with eight replications for each treatment, making a total of 40 sampling points. There was no influence of PTO rotations in the visible, invisible and total loss averages during digging. The PTO rotation in 378 rpm (6.3 Hz) presents smaller variability of visible, invisible and total digging losses. The lowest fuel consumption variability and average speed are obtained with 486 rpm (8.1 Hz) and 378 rpm (6.3 Hz) PTO rotation, respectively. Key words: Arachis hypogaea L., harvest losses, vibratory treadmill, control charts.

Global Plants and Digital Letters: Epistemological Implications of Digitising the Directors' Correspondence at the Royal Botanic Gardens, Kew

Abstract Digitisation is presenting new possibilities and challenges for the use of collections in both the humanities and the sciences. However, digitisation is also another layer in a longer process of selections shaping the collection—something which must be analysed on a case-by-case basis. This paper considers the epistemological implications of the digitisation of the Directors' Correspondence (DC) collection (1841-1928) at the Royal Botanic Gardens, Kew, made available through the Global Plants database. In order to avoid a polarised analysis of the end-products of archive and database, the selection process shaping this collection is traced from the writing of the letters and their reception into the DC at RBG, Kew, to the digitisation with corresponding metadata and the end-user searching the database. Particular attention is given the digitisation process and the knowledge produced by the project digitisers, as they combine close reading and database searches in writing the summaries of the letters for the metadata. This analysis of the DC engages with wider discussions about digitisation by emphasising the importance of taking a longer historical perspective, with particular attention to moments of selection, and highlighting the knowledge generated by those involved in the digitisation process. By doing so, the result is not a clear trajectory but a combination of losses and gains, disconnections and reconnections. Care is therefore needed to avoid replicating the invisible losses of extractive approaches to knowledge production, particularly in the context of collection-based biodiversity conservation.1

Losing images in digital radiology: more than you think.

It is a common belief that the shift to digital imaging some 20 years ago helped medical image exchange and got rid of any potential image loss that was happening with printed image films. Unfortunately, this is not the case: despite the most recent advances in digital imaging, most hospitals still keep losing their imaging data, with these losses going completely unnoticed. As a result, not only does image loss affect the faith in digital imaging but it also affects patient diagnosis and daily quality of clinical work. This paper identifies the origins of invisible image losses, provides methods and procedures to detect image loss, and demonstrates modes of action that can be taken to stop the problem from happening.

LOSSES IN THE PEANUT MECHANICAL DIGGING AS A FUNCTION OF THE DIGGER SHAKER ROTATION

Due to the many factors that affect the peanut crop, especially the care in the digging and equipment configuration are very important as it may affect significantly the losses in this crop. The aim of this work was to evaluate the losses in peanut digging as a function of different rotations of the digger shaker inverter. The experiment was conducted at Teaching, Research and Extension Farm at UNESP - São Paulo State University, Jaboticabal city, SP, Brazil. Was used seeds of peanut (IAC Runner 886 cultivar) and for the peanut digging was used a digger 2x1 (two rows per one windrow), pulled by a tractor with a power of 80.9 kW. The experimental design was a randomized blocks with five replications. Was used the tractor engine rotations at 20.0, 23.3, 26.7 and 30.8 Hz, which resulted in rotations in the shaker conveyer of 1.7, 1.8, 2.1 and 2.4 Hz. For the statistical analysis, was determined the descriptive analysis to permit a visualization of the general behavior of the data, determining measures of central tendency (arithmetic mean and median), dispersion (standard deviation and coefficient of variation), skewness and kurtosis. Was conducted to the Anderson-Darling test to verify the normality of the data, and when necessary, was proceeded to the standardization by the transformation. The visible, invisible and total losses were higher with the increasing of the digger shaker rotation.

Reducing food losses by intelligent food logistics.

The need to feed an ever-increasing world population makes it obligatory to reduce the millions of tons of avoidable perishable waste along the food supply chain. A considerable share of these losses is caused by non-optimal cold chain processes and management. This Theme Issue focuses on technologies, models and applications to monitor changes in the product shelf life, defined as the time remaining until the quality of a food product drops below an acceptance limit, and to plan successive chain processes and logistics accordingly to uncover and prevent invisible or latent losses in product quality, especially following the first-expired-first-out strategy for optimized matching between the remaining shelf life and the expected transport duration. This introductory article summarizes the key findings of this Theme Issue, which brings together research study results from around the world to promote intelligent food logistics. The articles include three case studies on the cold chain for berries, bananas and meat and an overview of different post-harvest treatments. Further contributions focus on the required technical solutions, such as the wireless sensor and communication system for remote quality supervision, gas sensors to detect ethylene as an indicator of unwanted ripening and volatile components to indicate mould infections. The final section of this introduction discusses how improvements in food quality can be targeted by strategic changes in the food chain.

Invisible Losses and the Logics of Resettlement Compensation

The necessity of compensating people negatively affected by conservation and other development projects has been widely acknowledged. It is less widely acknowledged that because conventional compensation assessments focus on material resources and their economic equivalents, many important losses incurred by resettlers are invisible to project authorities. Through ethnographic observations and interviews, we documented losses identified by people facing resettlement from Mozambique's Limpopo National Park. We also examined resettlement planning documents to determine why decision makers' assessments of natural resource use and value neglect losses residents identified as critical. Identifying, preventing, and mitigating invisible losses in resettlement planning necessitates a better understanding of intangible benefits residents derive from resources, which are often as or more important than their readily apparent material properties. These benefits include but are not limited to decision-making authority linked to owning land versus having the use of fields; ancestral identity and social belonging linked to gravesites; the importance of tree roots that provide a powerful sense of security because they suppress hunger in periods of scarcity; and the importance of people's location within social networks and hierarchies as they determine the benefits versus risks that will be incurred through resettlement.

VARIABILIDADE ESPACIAL DAS PERDAS E DA RESISTÊNCIA MECÂNICA DO SOLO À PENETRAÇÃO NO ARRANQUIO MECANIZADO DE AMENDOIM

A colheita mecanizada de amendoim é de fundamental importância no processo de produção da cultura, porém acarreta perdas consideráveis, principalmente na operação de arranquio. Assim, objetivou-se com este trabalho mensurar a variabilidade espacial das perdas e da resistência mecânica do solo à penetração (RP) na operação de arranquio mecanizado de amendoim em duas velocidades de arranquio. O trabalho foi realizado na região norte do estado de São Paulo. Os tratamentos avaliados foram constituídos por duas velocidades de deslocamento (V1= 3,5 km h-1 e V2= 4,7 km h-1) com dez repetições, com delineamento inteiramente casualizado (DIC). Após o arranquio, foram realizadas medições de RP utilizando-se um penetrômetro eletrônico, posicionado transversalmente às linhas de amendoim, a cada 0,01 m de profundidade, até a profundidade de 0,30 m, e a cada 0,15 m de largura, até o total de 1,80 m. Nos mesmos pontos, foram determinadas as perdas no arranquio, classificadas como visíveis (PVA), invisíveis (PIA) e totais (PTA). A velocidade de deslocamento do conjunto trator-arrancador-invertedor não influenciou as perdas avaliadas e a RP. A mobilização de solo ocorreu até 0,13 m de profundidade, havendo desnivelamento transversal dos órgãos ativos do arrancador-invertedor. Houve correlação entre PVA e PIA, e entre PTA e RP, porém os coeficientes de determinação (R²) situaram-se abaixo de 25%.

Occurrences and financial significance of bovine cystic echinococcosis in Southern Wollo, Northeastern Ethiopia

The study was carried out in Kombolcha ELFORA Industrial Abattoir to assess the current status and economic importance of bovine hydatidosis. Hyatid cyst count, characterization and economic loss assessment were conducted out of a total of 535 cattles slaughtered in Kombolcha ELFORA Industrial Abattoir. 93 (17.4%) animals were found harboring hydatid cysts. Thorough meat inspection in the abattoir revealed that 101 visceral organs were found harboring one or more hydatid cyst. The infection of the lung, liver, spleen, heart and kidney were found to be 50.5, 40.6, 1.98, 4.95 and 1.98%, respectively. From the total of 276 hydatid cysts counted, 135 (49.6%), 47 (17%), 20 (7.24%) and 72 (26%) were found to be small, medium, large and calcified cysts, respectively and 178 (67.9%), 12 (4.3%) and 72 (26%) were sterile, fertile and calcified, respectively. The rate of cyst calcification was higher in the liver than in the lung while fertility rate was higher among the cysts of the lung. The annual financial losses from organ condemnation and carcass weight loss due to bovine hydatidosis at Kombolcha ELFORA Industrial Abattoir were estimated to be 288,473.60 Ethiopian Birr (ETB) ($1 = 17.00 ETB). Thus, echinococcosis/hydatidosis is considerably a prevalent disease in cattle, with serious public health concern reflections and causes substantial visible and invisible losses in cattle in the study area. Key words: Bovine hydatidosis, economic loss, Kombolcha ELFORA, meat inspection, prevalence.
